Welcome to the University of Bristol my
name's Tim Gallager I'm the Dean of the
faculty of Science at the University and
it's a pleasure for me to welcome you
all here this evening to the second
annual Colin Pillinger Memorial Talk.
Now this evening there'll be two talks so we're
getting extra value there. I will be
handing over to Nic, Colin's son, to do
the introductions but let me just say
what a pleasure it is to be here, this is
the second of these lectures, the
first was also a well-attended great
lecture. I heard Colin give a talk here
some years ago about meteorites, probably
we're trying to work it out maybe eight odd
years ago, but I'm of a certain age and I
grew up with Michael Buerk during the
Apollo missions and watched deep into
the night
many of those and have been fascinated
by this ever since. My area of science
is organic chemistry, so it's a little bit
different, but I think that doesn't
diminish the thrill that one gets
around exploration whatever area of
science it involves. So, again, welcome.
We have an
opportunity to ask questions of our two
speakers at the end of this evening's talks
and I shall look forward
to that as well but I'd now like to hand
over to Nic Pillinger to carry out the
formal introductions.
Good evening ladies and gentlemen and
webcast viewers as well. So as you've
just heard my name is Nic Pillinger and on
behalf of the Pillinger family I would
like to also extend our welcome to you
this evening to this lecture.
After last year's interesting look at
the Moon and the lunar samples on
which dad started his career
we thought it was only logical to move
on to Mars and in particular Beagle 2,
the project for which he is most
well-known. Of course we didn't know at
the time of planning this meeting that
the mission would once again be so
topical. Colin always reminded us that
Beagle 2 was not a failure, just deferred
success. Tonight we'll be hearing more
about that success.
Firstly from Professor Mark Sims the
Beagle 2 mission manager who will tell
us about the project and in particular
the recent developments, and then secondly
from Dr Taff Morgan, who will be talking
about the expanding list of spin-off
applications from the Beagle project. So
I'd like to again thank you all for
coming and hopefully we'll see some of
you again next year and but now please
let me introduce Professor Mark Sims to
start the evening.
Good evening everybody.
Right so I'm going to talk about
Beagle 2, both as a mission and some of
the latest results we've got on imaging
Beagle 2 on the surface of Mars
Taff will follow-on with a talk about some
of the applications of the Beagle 2
technology. So how did I get into this?
Back in 1969 I was a
teenager
my father brought me to the University
of Bristol to see the moon rocks
somewhere in that queue I was stood
along with several hundred other people,
perhaps thousands in the end to queue up
to walk past a small exhibit of the
lunar rocks. So introduction to me, I'm
from the University of Leicester, I'm
Director of the Space Research Centre
there and Professor of Astrobiology and
Space Instrumentation. As I just said I
saw the moon rocks back in 1969 and I
can't remember whether it was Colin or
one of his colleagues was kind enough to
show me around the laboratory in 1969
and I thought this is fascinating, looking
at rocks from another world in this
case our Moon and I always vowed to
if I could be involved in space research.
This was reinforced in 1976-77 with the
landing of the Vikings on Mars. I should
say I'm local, I lived in Keynsham til
I was 18 and then went to University and
I've been back on occasions ever since.
Back in 1997 Colin started to float
the idea of Beagle 2 as a mission on
ESA's Mars Express mission and called a
meeting in the Royal Society in May of that
year. A group of us went along to listen
to what we thought was a completely
crazy idea.
It was crazy, it was great fun and
as we know nowadays it came excruciatingly
close to fully succeeding. So I
became in August of that year Project
Manager for Beagle 2, I took that
role through to 1999 when industry took
over the project management and I became
the Mission Manager for Beagle 2, which
meant I was responsible for the flight
operations, flying the spacecraft to Mars
operated on the surface with
the science being directed by scientists
organised by Colin at the Open
University. And also getting the
instruments there to the spacecraft. After
we lost Beagle 2 we decided to conduct
our own port post-mortem. There was a
full ESA inquiry which I'll come back
to later in the context of what we've
learnt at Beagle 2 since but we did our
own inquiry. That was the closure at
the time for the team because we had no
information on what happened to Beagle 2.
So, why Beagle 2? Why then? It was a unique
opportunity in 1997: ESA was proposing
Mars Express to fly in 2003, the Allan
Hills meteorite 84001 had hit the
headlines the previous year with
putative evidence of life, though
nowadays that's disputed, and there
was a restarting and accelerating Mars
exploration programme, including
Pathfinder and all the NASA missions
since. Why bother with Mars? I should
explain that the picture behind me, if I can
focus this, is actually the best view
you'll get of Mars from Earth.
It's a bit of a cheat because it's
taken with the Hubble Space Telescope. You
see this red world of thin atmosphere,
ice caps, etc, very cold very
inhospitable to life as we know it today
but four
billion years ago, 3 to 4 billion years
ago, it was probably warm and
wet
we have definitive evidence of that, lots
of evidence of water on the surface and
a good location for life to start so
that's why people want to go and explore
Mars. At the time Colin's group and other
people within the UK were world-leading
geochemists - they still are today - and so
it was natural that Colin would propose
a lander and try and answer the question
"Is there, or was there, life on Mars?" using
the instrumentation and techniques he
had developed. Also within the UK we're very well
known for our innovative engineering, our
innovative instrument design and so that
folded into the mix of Beagle 2. And it was
unique opportunity back in 1997, it was
the only European mission going to Mars.
We must take that opportunity or not do it.
Colin saw this as an ideal mission to
integrate both the academic interest in
going to the planet and the industrial
capability within the UK. And of course the
high publicity and education value of
doing such a mission as Beagle 2.
Beagle 2 science was unique - objectives at the
time:
detection of past life - extinct life - or
extant life - present-day life - by looking
for organic compounds in the soil,
or regolith as it's technically termed,
the analysis of subsurface material in the
regime, its geochemistry etc, and the first
attempt at crude radiometric dating by
using the decay of potassium to argon in
rocks. All of those have only just
started to be achieved by Curiosity, a
long time after Beagle 2. So the science
programme was looking at the geochemistry, looking
at the minerals, how those minerals are
put together in terms of what's called a
protology, looking at chemical and physical
analysis of the atmosphere,
looking at how the landscape has changed
the so-called geomorphology and
measuring dynamic environmental
processes on the planet today. And doing
some astronomy on the planet as well
looking at the Sun, the bright stars in
Phobos and Demos, particularly the latter
in actual fact because that would enable
us if we got a picture of them to locate
our landing site with high accuracy.
In terms of the engineering you've seen the
model of Beagle 2 outside it's roughly
1.8 x 1.6 metres, not that big, mass of 69
kilos of which about 8.7 were for the
instrumentation plus some hardware on
Mars Express in order to spin it off the
platform. Power is very very low for
Beagle 2, it typically was about 10 to 20
watts, I like to think of it in terms of a
modern light bulb that's the total power
that Beagle 2 consumed and it had
lithium-ion batteries you're all
familiar with those in your smartphones
tablets etc and
state-of-the-art solar arrays back in 2003
built of gallium arsenide to get the
maximum amount of power. Thermal design
on Mars is tricky because the average
surface temperature on Mars is minus
40 degrees C and at night it goes down
to well over minus hundred. so you've got to
have a good thermal design. A lot of the
missions use radio isotopes to
generate heat, Beagle 2 didn't, it had a
very clever design using the solar
collector and it was designed to operate
for a nominal hundred and eighty days on
Mars, or 180 sols as they are called, talking to
both NASA missions Odyssey and Mars
Express. So Beagle 2 as you can see
outside is this pocket watch-type
design, it had to fold up in order to get
all the things we wanted in the
volume we were allowed for Beagle 2.
It was highly integrated, no redundancy and it
deployed some of its
instruments on a small robotic arm and
we'll come back to that we come to the
questions.
I'm not going to go too much through the
details of Beagle 2, some of that's for the
people who are interested in the
technical detail, but that's a
cross-section of Beagle 2 in terms of
its base unit, the gas analysis package you
will hear about a bit later,
the electronics etc and the
transmitter and the arm and the
so-called PAW assembly which was a
combination of instruments which we'll
talk about in a second. So getting a
Beagle 2 the surface of Mars - the so-called
six to seven minutes of terror - it's the same
for every mission. You have to slow the
thing down, the first way you do that is use
friction in the atmosphere which heats
the heat shield to very high
temperatures. You then want to stabilise
the probe at supersonic speeds as it
goes to subsonic speeds, it has a small
pilot chute and a rear cover which were
then detached and then the main
parachute was deployed and Beagle 2, for
people who watch the animation, as you saw
was cushioned on its impact by a set of
airbags which were inflated with
actually ammonia gas. On impact on the
surface the main chute would have cut
loose, Beagle 2 would have bounced across the
surface and then deployed itself. So on landing
it would have looked something like this:
large air bags which were about 1.2 metres
across, Beagle 2 remember at this stage is
still folded up, would have been
pushed away by their internal gas
pressure. Beagle 2 would have fallen to
the surface and then deployed itself. So
a bit of project history, conceived as I
said back in 1997, the first official
meeting was in May that year. We then
wrote a proposal to ESA which I
hand carried on a plane to ESTEC in
Noordwijk in Holland and delivered
it with a few hours to spare to the
deadline. In May that year
the European Space Agency came back to us
and said it's far too heavy
you're going to have to redesign it so I was
actually on holiday in Scotland and had a
plaintiff phone call from Colin saying
we've got a problem
what are we going to do about it so when
I got back off holiday we had a meeting and
redesigned Beagle 2 which originally had a
small rover on board down to a static
lander of 60 kilos and in the end it ended up being
69. 1999 was a busy year in
terms of the funding we got industrially
based project manager in February in
July we got some initial instrument
funds and then later in the year
Lord Sainsbury gave us our initial
government backing, the ESA science
programme committee which has to approve all
missions approved us in November that
year and then in 2000 we
were vetted by NASA, John Casani who was
Chief Engineer at the Jet Propulsion Laboratory
at that time came over and did an
extensive review on Beagle 2, his
conclusion was what we're doing is
nuts but it seems to work so keep going.
Beagle 2 was built as a spacecraft in
summer 2000 to February 2003. In October 2002
which you'll note is very close the
launch which is in 2003 we started the
flight model subsystem integration and
in January 2003 the lid was closed on
the lander for the last time on Earth.
The pictures by the way up to the right
are some very pretty pictures from Mars
Science Laboratory. So we got Beagle 2
the launch site by the skin of our teeth
I think we'll put fully accepted that
and it was launched on a Soyuz Fregat
launcher back on the 2nd of June 2003 and
19th December we said goodbye to it. It
was spun off the main spacecraft, I'll
show you a picture of that in a minute,
and landing was due in the early morning
of Christmas Day 2003 and then we never
heard from it. We were
expecting a transmission from a NASA
spacecraft we expected a transmission to
Jodrell Bank, we heard nothing.
March 2004 we essentially
closed the book on Beagle 2 and did our
own post mortem. In November 2014 we
started to see some images of what could
be Beagle 2 on the surface of Mars and
I'm not going to spoil the latter part of my
talk by talking about that now the
picture to the top right by the way was one of
the latest pictures by Opportunity on
the surface of Mars it's starting to
explore this Valley on the side of this
crater and the column in the distance is
actually a dust devil on Mars which is a
few hundred metres across.
So, back to Beagle 2 hardware
this is a picture of the PAW assembly
we have two stereo cameras, microscope,
corer-grinder, x-ray spectrometer which
looked for the elemental composition of the
rocks and a Mosbauer spectrometer which
looked at the iron content and then
bolted along the back of the PAW was
a so-called mole which was this self
burying subsurface drill to go collect a
sample from deep beneath the surface of
Mars. This is the gas analysis package, more
of this later in the second talk.
This is Beagle 2 just before we closed
the lid showing the PAW assembly
mounted down in the base with all the
shiny material is a multi-layer
insulation to keep Beagle 2 warm and
happy when it was on the surface of Mars.
The PAW assembly didn't have any it was
actually designed to work at the ambient
temperatures on Mars and the
electronics worked down to minus
one hundred and ten degrees C.
The lander just before the lid was
closed, solar concentrator over the
battery, the gas analysis package is here
and this is the PAW with the robot arm
folded behind it. So closing up Beagle 2
delicate process and then with its
parachutes and it's airbags everything
had to be stuffed literally into the
heat shield, front shield here, rear
heat shield at the back, so you can see
how small Beagle 2 was. Taken to the
launch site which was Baikonur in
Russia and mounted on Mars Express.
Mars Express isn't that big as you can
see by the scale of people and Beagle 2 is
now covered in rather nifty black MLI as
that is a higher performance than the
shiny stuff. And 2nd June 2003
it was successfully launched and on its way to
Mars and we checked it out a number of
times on the way to Mars including
updating the software, as far as we were
concerned Beagle 2 was healthy and ready
to land on Mars. At 08.31 on
the 19th December 2003 Beagle 2
was spun up and it was spun up in order
to give it some stability before it hit
the atmosphere, think of a gyroscope, if you
try and topple it, it
will tend to stay upright so that's why
Beagle 2 was spun up and this was a
picture from a camera that ESA put on the
top of Mars Express showing Beagle 2
disappearing off into the darkness and
off towards Mars, ejected at the correct
spin rate and at the correct velocity. So
where was Beagle 2 aimed at? It was
aimed at a place called Isidis Planitia
it's a big old impact site on
Mars, an asteroid hit four to four and a
half billion years ago it was then
backfilled with what we think were
sedimentary fluvial
rocks and also igneous rocks and this is
a close-up of the Isidis basin that
little area there which actually isn't that small
it's over 60 kilometres long is where
Beagle 2 was targeted
So what are you looking for if you lose
a lander on Mars? You're looking for
something extremely small, 1.8 x 1.9
metres if it's fully deployed and the
list there which I'm not going to go
through so I'll leave you to read
while I talk shows you all the different
characteristics of the various
components of Beagle 2 all of which
with the exception of the parachute very
very small. The air bags would have
deflated and unfortunately the airbags
we should have made them bright green
but they were orange and that's the same
colour as Mars so they
would have disappeared unfortunately
I'd love to see the airbags in some of
the images we've got today.
So how do you look for a lost lander? Well
we look for a lost lander with Mars
Express and the cameras going around
Mars at the time but they're relatively
poor resolution. They are good resolution
in that they're metres or tens of metres but
you're looking for something which is a
couple of metres across at most. In 2006
Mars Reconnaissance Orbiter got
into orbit with its HiRISE imager
which it has in orbit about 250 to 300
kilometres above the surface of Mars and
it can resolve its smallest pixel size
is about 25 to 30 centimetres and we
gradually got a series of images across
the landing ellipse for Beagle 2 which
was recalculated in 2006
shown as the blue ellipse type shape
on the left and the stripes are the
images
so you've got 30-centimetre pixels, you've
got red-green-blue colours, you've got
stereo
capabilities with HiRISE but each of
those strips is 6 x 15 kilometres and
contains a billion pixels. Beagle 2 at its
largest extent is 8 to 10 pixels
across so it really is
needle-in-a-haystack time. Various of
people including myself started looking
through the HiRISE images and you
start imagining things, you start to see
Beagle 2 on the surface everywhere
the reason by the way there are some
images off to the right is when
Beagle 2 landed the atmosphere was
pretty thin, we wondered whether it had
overflown its landing ellipse, in
actual fact we found it where the green
cross is very close to the centre only
five kilometres away. And so after a while
you get fed up of looking at rocks which
might have been Beagle 2 and gradually people
dropped off looking at the images, a few
hardy souls kept going, one of which was
Michael Croon who worked for the European
Space Agency during the Mars Express mission
and actually was part of the operations team
which delivered Beagle 2, and he noticed by
chance that there was an object in 2
overlapping images. You look at those
images on the left hand side you'll see
there's very few which overlap and he
cycled back and forth between two images
and he saw an object which stayed there
meaning it wasn't noise in the camera, meaning
it was a real object and it was bright
and he alerted the HiRISE team in
Jet Propulsion Laboratory they alerted
us and as they say the rest is history.
This is a picture of the Beagle 2
landing ellipse, it's 60 kilometres by 10
kilometres and this is the little area in which we
found Beagle 2. This is some work done
by the University of Aberystwyth which
looked at the heights across that area
where Beagle 2 landed you can see the
scale it's only a few metres and the
slopes are a few degrees basically so it was
a great place to land and this is if you
like the discovery image which we put
out a press release back in January 2015
Beagle 2 came in on this trajectory
here and we see an object here which is
Beagle 2, object here which is a
parachute, object here which is a rear
cover. If you can remember the sequence
that we saw in the entry descent and
landing.
Currently we have 8 images including some
in colour but we're looking for ideally
all the components of Beagle 2. This is
some image processing done by Tim Parker
at the Jet Propulsion Laboratory, on the
colour image it is slightly
different resolution where the camera
works you still see the main parachute,
you see some peculiar impact here which
we think is a rear cover, you see Beagle 2
up here but you also see a bright spot
just north of Beagle 2, I'll come back to
that in a second.
This is a close-up of the impact point,
we think it's the back cover and the
drogue chute.
Why is it black? The soil's been turned to
black because Mars has a very oxidized
surface, if you like Mars is a rusty planet and
then the impact disturbs that surface
and exposes soil which has not yet
been oxidized, which tends to be darker
in colour. So Tim Parker did the very best
he could, combined all the images together
and we got what we call the Mickey Mouse
shape, it's the right size for Beagle 2
about two meters across, it doesn't cast
a shadow by the look of it, it's bright
it's flat shiny surfaces, more about that
in a second. As you can see the scale bar
is 10 metres.
Jan-Peter Muller, University College London, who's one of the UK's
top image processing specialists, has a
lot of computer techniques for
producing so-called super resolution
images. He released this data back in
April this year and you see close-ups of
the various targets, parachute actually
might look like a parachute
now, the pilot chute and the rear cover and
the lander and what we now know is the
front shield this bright object we saw
and we'll come back to that in a second
So why do we think it's Beagle 2? Is it
not just a shiny rock on the surface of
Mars? We have a number of discrete
elements, they're expected sizes and shapes
and the height, they're not very tall objects
Beagle 2, if you look at our model out
there, it's about 80 millimetres deep
some of the sections of it. They're
in the right sequence in terms of the
relative positions you would expect the
parachute to be first
you would then expect the lander the
heat shield could land by the lander or
even longer
that's what we see and the pilot chute
and the rear cover would be off to one
side. There are expected separations they're
the right kind of separations we do
computer modeling with. They're the
expected colour. They're in the expected place and
what led to the recent press release
there is a glint. The image changes
drastically with the Sun angle it's taken
at. So before we get on to that what
should we see? We see a lander, we have
very good evidence of that being a lander,
we see a rear cover and a pilot chute, we have
evidence of that, we see the parachute,
we don't see the airbags for the reason I have
said though I keep looking at the images
and wondering is that an airbag? Front shield
we see, combination separation, so it's
definitely Beagle 2. It's even more
definitive after recent work.
Unfortunately ExoMars Schiaparelli lander
crashed on Mars a few weeks ago
these are the latest images from
HiRISE showing unfortunately the point
at which it crashed, the explosion point
with unfortunately bits of the lander
around but you see the parachute and the
parachute does look like the Beagle 2
parachute. As far as I'm concerned it's the
last piece of the puzzle, in terms
definitively knowing whether it's Beagle 2. So
what did the data tell us? Remember you're
looking at a blobby shape,
pixel size of 25 centimetres even
with aligning a hundred eighty rocks on
the surface which is what Tim Parker did and
matching the images this is as good as
you get.
And you can put Beagle 2 on it, and as
you see it's the right size. So you've
got the base section, the lid section and in
this case 2 solar panels. In the
announcement we made in January 2015 we
said it was at least two panels deployed.
That glint effect kept nagging at the
back of my mind
everybody is familiar with it if you
look down your road on a sunny day the
glint of the Sun off the windows down
the road, they drastically change
brightness and your noticability depending
on what the angle is to the Sun. So as
of 2016, the image data is consistent with
only partial deployment, base and lid
are open and one or more panels, perhaps
maximum three were deployed but the
kicker in all this if the fourth panel
didn't deploy the radio antenna was
under that fourth panel and that was not
a design error it was the only place we
could put that radio antenna given the
constraints that we had in terms of mass
and volume of the spacecraft. So as I say
this glint effect kept digging away at
the back of my mind, and because of a chat with
a friend over coffee one night I got
introduced to a team at De Montfort
University, named there and the team
that worked with me at Leicester is also
named there, and Jim Clemmet who was the
Chief Engineer of Beagle 2 up until
the beginning of 2004. The
idea we had was to build a virtual
reality model of Beagle 2 - younger
people in the audience will be familiar
with that - a simulation of Beagle 2 on the
surface of Mars and model its optical
appearance and its reflections as the
Sun angle changed and could we reproduce
what we're seeing with the HiRISE
imager and we've done that by
using our human brain and eye, which is
very good at pattern matching, it's also
very good at false pattern-matching as
well as we all know but we've done some
mathematical techniques as well we've
done correlation analysis we've done a
difference between the simulated image
and the real images and we ratioed the two
as well and all of this is to try to
avoid the problem of image
processing. Image processing does
potentially add false things to an image
most of the time it doesn't but we're
trying to derive the deployed
configuration of Beagle 2. The result of
all this is shown in this overhead here
this is the original HiRISE image,
very blobby, so there it is as raw
pixels and you don't see much in terms
of the detail of Beagle 2. This is the simulated
3D image of Beagle 2 on the surface. This is
the close-up and as you can see two of
the panels are heavily illuminated at this
Sun angle, one isn't. The base is and the
lid is and you can actually get a
reasonable match between the two and
in actual fact you know from that you can work
out the configuration of Beagle 2 on the
surface in terms of north-south orientation.
It will never be an exact match because
we have no idea where these pixels start
with relation to Beagle 2. We tried a whole
series of different pixelations
moving the edge of those pixels across
this was the best match we've got and
that's actually consistent across three
different Sun angles and is consistent
with either 3 or
4-panel deployment with three panels
matching slightly better. It was a six-month
analysis there's more we can dig out of the
data, we haven't so far. If three panels
deployed then that perhaps
answers what happened to Beagle 2. If
four panels deployed and the simulation
shows it didn't open to 160 degrees like
the other panels it opened to 130 which was
nominal for the mission if it's got
enough power, the question is if
that fourth panel did open
why couldn't we talk to it? Is it a timing
error? A software error? Flat battery?
We'll probably never know. And this is a
simulation of the heat shield, three
different Sun angles, and these are the
reproduced pixelated images> Barely see it
there, quite strong there, hardly see
it at all there and these are the real
images at the bottom which I think is a
good match and it means the heat shield
is laid on its side sat on the surface of
Mars. So what does it mean? To sum up, well Beagle 2
successfully entered the
atmosphere, its entry descent and landing
which is the seven minutes of terror
worked, lander software started, deployment
probably started but maybe didn't finish.
The reason, we have a long list, we've done a lot of
engineering analysis, Jim Clemmet has
and even if the fourth panel deployed there's
at least 21 reasons why it may not have
worked. My personal favourite -
this is a human being talking rather
than a scientist - would be the bad luck
scenario. A hard landing because of the
thin atmosphere perhaps distorted the
structure, that's punctured the
airbags and Beagle 2 didn't fully deploy.
So it's on Mars, it's not lost, it's worked, it's
intact on the surface. So, success or
failure? Depends on your viewpoint.
It depends on your viewpoint in time as
well. In 2004 the team which was over 400 people
that worked on Beagle 2 were
pilloried
at the time in terms of "this was a failure,
what have you done? You've wasted all
this money, you haven't succeeded." As we
know now it got not as Rob Manning, Chief
Engineer at JPL says, you got 99
percent of the way there, you got the
difficult bit done, it's a pity the last
little bit didn't actually work. So I
count it as a success. UK and ESA landed
on Mars in 2003, successfully entered the
atmosphere, first controlled landing
on another planet,
just ahead of Cassini-Huygens, entry
descent and landing system was an
engineering success.
You might count the fact it didn't fully
deploy, if that's the case it's a failure.
It was an innovative project, it bound
together academics, industry and
the general public. People still remember
Beagle 2 today as evidenced by the fact
that you're here tonight, inspired
many people, children, adults, general
public and the scientists. And from the
UK point of view, it trained a whole
generation of engineers and scientists
in terms of planetary science and
engineering which has led indirectly to
the ESA Aurora programme, and the ExoMars
programme, the trace gas orbiter which is
successfully orbiting Mars, the Schiaparelli
lander which unfortunately didn't
succeed and the ExoMars rover in 2020.
The lessons from Beagle 2 are being used in
ExoMars and all sorts of other missions,
again a success. Didn't communicate after
landing, didn't provide science from the
surface. It may have operated for some
time on the surface of Mars. As a scientist and
engineer I would say the probability of
it still operating today is extremely
low. As a human being I'd like to think
it's still there. So credits and

Thank you very much
Well I'm with you Mark I think it was a
success so I'm sure everyone here did
as well and so what I'd like to talk
about is the legacy of Beagle 2
Actually more the legacy of Colin
really and it's to do with the team that
Colin built that worked on Beagle 2
and other space missions and what we've
been doing to try and translate our
know-how and our technical knowledge to
solve some of the problems back here on
Earth and there's a list of them there and I'll
probably go through them now with you but
I'll start with GAP - the gas analysis
package. So this took up about
one-third of the Beagle 2 lander it was
there to look for the signs of life on
Mars. So it was going to sniff the
atmosphere and look for methane which
again is a potential indicator of the
presence of current life
it was also going to take rock samples and
it was going to burn the rock samples and
release carbon dioxide and look at the
stable isotope composition of the carbon
dioxide and that would give us a
fingerprint to indicate whether or not
there had been life present on Mars in
the past. The Gas Analysis Package is a
miniaturisation of three of our
laboratory systems. So these are very old
pictures now, these are from our old
building in fact, and these are all mass
spectrometer base systems, they're all
about the same size as a family car so
we shrunk all that down into the size of
Beagle and I actually joined Colin to
work on the the system on the top left
there, a system called Miranda. It was a
system that my colleague Andy Morse had
developed - at least he developed the mass
spectrometer part - for his PhD. So Colin
was actually doing space
technology transfer in the
1990's. I joined the group in
1993 so even before we had a name for it
Colin was doing it, so that's the kind of
person he was.
These systems, the one on the bottom is
is for doing carbon dioxide again as you
can see the systems are pretty huge. The
team that Colin built to
miniaturise it is shown
here. There are eight of us as well as
Colin, what's amazing is that seven of
us are still at the Open University. Jenny is
working now in senior
management but six of us are actually
still working in space instrumentation
and in technology transfer and again
you'll see a lot of these faces as I
go through the talk. Daz, who's the guy on
the right hand side, he's now left us but
he's a CAD engineer and he now works in
in the space industry and has been
working in satellite manufacture. At the
back left is Simeon Barber and
anybody who came to the talk last year
would have heard about the the idea of
going to the Moon and looking for
volatiles on the Moon and Colin
kicked off that project with L-VRAP
and it is now Simeon who has picked up
that mission and we hope in 2021 to
part of the European Space Agency and
Russian Space Agency mission to the Moon
to the poles to actually look for the
presence of water and volatiles with the
idea being if you got water on the Moon
you can start to use that
as a resource
Daz was a CAD
designer. On his computer he had a zoom
button.
Unfortunately my finger stays the same
size so this is us actually trying to put
together the Gas Analysis Package in a
clean room
I'm the one
impersonating a teapot on the left-hand
side there, the guy doing the work is the
engineer who is doing the
the wiring, but you can see those are
the kind of conditions we built Beagle under
and this is actually before it went into
the sterile facility - the AAF - so this is
actually the clean room before the
really really clean room which Judith
of course was very prominent in actually
getting built and it was the
cleanest place in
Europe at the time. This is now an
animation of how GAP would have worked
on Mars.
So you might have seen the video at the
very beginning, you're seeing the arm
bringing the sample, so in a minute
you'll see the arm come down and the
idea was we would collect rocks from
beneath the surface of the Martian surface
to then give us samples of rock that
were not oxidised. It would then drop
down into a funnel and then into a
carousel system with a series of ovens.
Each of these ovens was about the size
of my little fingernail, made from
platinum and capable of getting to
over a thousand degrees centigrade. As
you'll see the carousel turns around
then goes to a tapping station and a
ball was driven down into the tapping
station, deforms the platinum bucket,
you get the electrical connections and
you can heat your sample up. You can do
that in a stepwise manner and that allows
you to fingerprint what's present in the
actual sample. So you turned the rock
into a gas, mainly carbon dioxide, and that
then goes into a chemistry set and the
actual sample is then processed to clean
it up and then it goes into the mass
spectrometer for analysis.
So these are the kind of analyses that
Colin and Ian Wright and the rest of the
group do with meteorite samples back in
the laboratory. So we shrunk the big lab
systems and we do the chemistry on Mars. So
once the gas goes into the reactors it
gets cleaned up and then it goes into
the mass spectrometer.
So when it enters the mass spectrometer
it's ionised - in a minute you'll
see some flashing - and that basically
turns the gas from neutral to ions. You
can accelerate that using voltages and
then it goes through as you can see
there through the slits so that allows
you to focus the beam and the beam gets
fired around the actual magnet which is
in the shape of a right angle, it's a
six centimeter radius and that allows
you to separate the different masses
present. So in the case of carbon dioxide
we look at mass 44, 45 and 46 and we're
looking at the ratio of those compounds,
you'll see they'll hit a bucket in a
minute and you can actually count those
ions. And by counting those ions you get a
ratio and by looking at that ratio and
comparing it to standards you can then
relate that back to things on Earth and
whether or not things are biological or
or inorganic in origin. And again, that
mass spectrometer you'll see a bit later
on, we're applying it some samples
here on Earth but it
works in pretty much identical to the
way that the GAP would have worked.
Beagle 2 was not the first space mission that Colin
worked on. Despite what you might have
seen on the TV,
these are the people behind the Ptolemy
instruments on Rosetta. Colin, Ian Wright
with his long hair there, he had short hair
in the previous picture, and two
colleagues from RAL Space - Ray
Turner and Eric Sawyer, and they proposed
Ptolemy as an instrument to go to the
comet on board the Rosetta mission, I think it was
in 1994-95 it was funded and in 2001 we
developed the Ptolemy instrument, or by 2001
rather, and this is the Ptolemy instrument so we
shrunk something the size of a car down
to something literally the size of a
shoebox. It was a gas chromatograph
isotope ratio mass spectrometer but
basically it was designed to do similar
measurements to Beagle but
different
so it was going to measure different
chemical species and those would have
answered questions like did water on
Earth come
from a comet and are the building
blocks of life, the organic compounds we are
all made from, our they present on the
comet. On the right hand side you can
see Ptolemy onboard the actual Philae
lander, so we were the very very first
thing that went on the lander. We
delivered that in September 2001, we launched
in 2004, we chased the comet for 10
years and four billion miles until of
course we landed in 2014
Unfortunately Colin didn't get to see
this picture, this is an image taken a
month before we landed. So this is
probably the world's most expensive
selfie - 1.4 billion - but it is beautiful
it is an absolutely fantastic image
taken by a camera on the lander looking
out over the orbiter looking at the
solar panels and also the comet in the
background. Again you can see the jets
coming out the neck and this picture
also has one of the oldest and one of the
youngest things in our solar system in
the same picture, it's a beautiful image.
Before we got to the comet , until about
August 2014, we were all working on the
assumption that the comet would be the
shape of a potato,
so it's kind of elongated. Once we had
the images back we then realised we had
more like the shape of a rubber duck
so we then spent several hundred pounds
getting a 3D printed version of the
comet made so we could decide where
we were going to land.
Having spent all that money on this 3D
printed version we decided not to
mark it and so Andy Morse popped down to
Morrison's, and bought a 69p duck.
Simon's son Matthew then marked up the
landing site and in fact the landing
site is J - Agilkia - that's where we
actually did end up landing. It's not where we
ended up staying but it's where we
first landed andso we
actually took this to the Science
Museum for a kids
event and the Science Museum got really
excited and this duck is now saved for
for history or whatever you want to call it so
just by marking it with a felt
pen we've added quite a bit of value to this
Morrison's duck. So if anybody
wants to have any more signed I'm
sure we can get Matthew to mark them up
for you. Now we actually did
land of course and as you saw we had a very
exciting ride. There isn't time to show you the
video but you know that week of
landing was probably most exciting
tiring frustrating but ultimately
satisfying week and we actually
managed to take data almost immediately
after the first bounce so whilst
everybody was celebrating at Darmstadt
where all the politicians were, those of
us in the lander centre knew there was a
problem immediately. People knew the
harpoons hadn't fired, people knew it was
spinning, we couldn't be on the surface.
But we didn't care because we already had data.
We got data by sniffing the gas
that was thrown
up and if you want to know what a comet smells like
under your chair there should be a
postcard
Some of you have
probably smelt it already
This was something we did for The One
Show, my colleague Colin Snodgrass did,
and comets do not smell good.
In fact Alex Jones on The One Show
described it as smelling like her
granny's toilet cleaner
I warn you that the smell does linger so
I would put it down otherwise when
you walk into home tonight you'll be
smelling of toilet cleaner. So the problem
with space missions is they're a bit like London
buses, we had three together with Beagle,
Rosetta, Cassini-Huygens. We're still
waiting for the next one. So we had to
look at how we could use the technology
we developed so here you can see the
kind of heritage of the the kind of
stuff I'm about to speak about. So it
started with the kind of systems that Ian
and Colin and Monica and other people
developed at the Open University for
analysing meteorites. We then went
through obviously Rosetta, Beagle 2 of
course and then we had various other
funding sources that allowed us to
look at a whole range of different
applications for mass spectrometry back
here on Earth. And the reason we could do
that is because we developed this world
leading infrastructure - the labs
we have at the OU are fantastic, we're very
well-equipped and again most of that of
course was down to Colin's funding activities
and as important as that, as well as
having the technology is having the
multidisciplinary skillsets so that GAP
team you saw there, we had geologists, we had
engineers, we had CAD people, we had
chemists, physicists and when you put
that disparate skillset
together which is what space missions do
then you have a very very powerful
resource which you can work in
partnership with end-users to develop a
whole range of new capabilities. So
this is just a summary of some of the
people we have worked with and there is over 3
million pounds worth of activities there and
in fact the the most recent one
Leonardo and ESA is the space
mission that's going to go to the Moon
and that itself is a £3 million
pound project. The most applicable
technology that we've developed directly
for a space mission is this valve.
This is a valve that was used to control
the gas on Ptolemy to allow us to
control the flow of gas into the mass
spectrometer. We then redesigned it and
we've managed to patent the actual
design because we made so many changes
from what we originally had
and just last year we have actually
signed a manufacturing license agreement
with Surrey Satellites so Surrey are owned by
Airbus Defense and they're the people
who put up geostationary satellites so
who knows in a few years time the reason
you can watch your Sky TV may be because
it's been controlled by one of these
valves. It's also been evaluated by NASA
and NASA are looking at it for Resolve
which is the next Mars mission or one of
the future Mars missions, and again this
valve technology could actually go
into space again. And again we will be
using it for the Moon mission. The
biggest impact project we've had is
actually developing a system just down
the road in Abbey Wood, the defense
equipment support MOD. They had funding
to look at developing the new Successor
submarine which is the Trident
replacement submarine, which are the
submarines that basically keep us safe.
And we were approached in 2010 to look
at whether or not we could develop a new system
for them based on Ptolemy and we did develop
a system, it took us less than nine months
although we delivered the box to
Glasgow, or Faslane, which is in Scotland.
The submarine was there, the box was
there, unfortunately the paperwork wasn't.
So we had to wait six months before we
could actually put it on trial but this
system has been on sea trial and
basically it has changed the way that
BAE systems designed submarines for the
future. So currently there's an air
monitoring system on board which is an
American system, there's only one of them.
A submarine can't go to sea without
that working, and our system is much
smaller, it's faster, it's better, it's cheaper
and we'll save the the government and
the MOD a lot of
money but more importantly it allows
them to have three systems on board so
it makes the environment much safer for
our submariners and again there's the
project team and again you'll
recognise at least four of those people from
a previous picture. So we've broken a
30-year American monopoly, currently all
UK submarines use US
capabilities, but that technology is really
old now. As I say it's faster, it's better
it's cheaper and it will be a British
company that take this forward. I think
that they've just announced they're going to call
it Dreadnought. It's going to be the first
submarines designed to have women on
board and have facilities for women, it's
the first time they've had an educational
facility on board a submarise. So the OU
already provides online courses for
submariners but now they will actually
have the ability to do training. So
it's very nice to be part of
this and hopefully as I say
this technology will last for the next
fifty or sixty years. We do develop
systems as well for commercial
applications. I like to show this one
because it's the first time I've ever
been called a boffin. So we developed a
robotic system that's been used by
the world's largest fragrance provider
a company called Givaudan, who are based down in
Ashford in Kent, and they produce all the
kind of smelly stuff that goes in to
products like toothpaste and washing
powders, shampoos and all the expensive
stuff that you buy. So I hate to burst
your bubble but when you buy really
expensive perfume it was probably made in
the factory that used to be run by ICI
down in Kent. But we managed to
provide a system that allows them for the
first time to do quantitative
measurements about their perfumes and so
they're very happy and again
it would be a nice REF story for us.
In terms of health then probably
the longest project we've been working on
is this one and the answer to the
question can dogs smell cancer is yes
they can and so can we.
So we've copied what dogs do and we've
used a commercial
system - quarter of a million pounds' worth
of equipment and we've worked in partnership
with clinical partners at Amersham
Hospital but also at Cranfield University
the bioinformatics group to look for
patterns of compounds that could be
indicative of cancer. In fact this work
came about because Judith came to me with a BBC news
website article where original work by
the dogs was published just after this
and that was back in September 2004
so we've actually developed not only
a test for bladder cancer but also
prostate cancer and that's really
important because currently there is no
non-invasive diagnostic test for
prostate cancer we rely on something
called the PSA test which is a blood
test
PSA test, there's over one hundred and twenty
thousand positive PSA tests in the UK per
year, 80,000 of those are wrong so men
have been told they might have cancer
and then going through procedures which
are very invasive to then be told that
they actually didn't have it after all
so we developed a sniffing test, so again
we can sniff comets, Mars,
submarines and now urine, and we're using
a patent profile to actually allow us
to identify whether or not
the patient has old man's prostate, or
benign prostate hyperplasia, or cancer
Our
accuracy is around about 83%. We've done
a sample of round about a hundred
patients so the next stage really is to
take it forward and actually to blind trials
and everything else and we're
looking for partners to do that with.
A few years ago I
crossed from academia into the dark side
of commercial work and I blame the two
older gentleman on the
left-hand side there, Ejaz and Phil
there were two guys from RAL Space, two
professors, and in fact Ejaz had
developed the ionisation source on
Ptolemy which I never knew until I
met him, and they approached me about
taking the technology and using
effectively... Well they had an idea for a
STFC patent to look at the gases that
cause helicobacter pylori. So both these
companies have been sponsored by the
European Space Agency, the business
incubation Centre at Harwell, so funding from
ESA to technology transfer and also
from Innovate UK through the
Harwell Space Launchpad. The second
company, I took a phone call at RAL
Space from my business partner Jason, who's
the guy on the right, he's a pest controller
from Manchester, he said I think I can
smell bedbugs,
can you build me a machine that'll do it
because my knees are going and I'm getting
old, I need to build a machine. So we
formed the company and we're currently
in negotiations with the world's largest
pest control company on how we take this
technology forward. So in terms of
helicobacter pylori why is it important
well actually I realised when I was preparing
the slides that when I joined the OU
Colin had a PhD student who'd just
finished working on this so that was
back in 1993. It's only
taken me 23 years to catch up. The
idea is helicobacter pylori is a bacteria
that about one-third of the world's
population and up to forty percent of the
UK population have had it, H pylori. And in
the developing world there'll be up to
eighty percent of the world's population
infected usually because of poor
sanitation and transfer of faeces or
bacteria. And most people get it
when they're kids and the problem
with it is is the bacteria gets
beneath the mucus layer in your stomach and
it causes ulcers. So it's not stress that
causes ulcers, it's now been proven that
its bacteria and up to ninety-five
percent of duodenal ulcers and up to
seventy-five percent of gastric ulcers
are caused by this bacteria. It's quite
easy to treat with antibiotics and
protein pump inhibitors but the actual
difficulties getting the people to the
to the treatment or actually to the
diagnosis. Up to 3 percent of
those infected with
helicobacter pylori can go on and get
cancer. So it's an important thing to
treat and just to give you an idea of the
numbers, if you just look at India and
China alone, and in fact I was at a
presentation a couple of weeks ago where
they said that the Chinese government
might actually start testing all of
their population because the
cost of not treating it
early on are so huge. So you could be
looking at over 22 million tests. What
are going to do, well we're going to look
at carbon isotopes, exactly what we did
on Mars, but this time instead of it coming from rock
samples it comes from breath. If you give
somebody an isotopically-labeled urea
tablet the bacteria break down and
metabolise the carbon dioxide, and it comes
out in the breath and you can measure
that shift. Now the difficulty is in most
systems
are, like the lab systems you've seen before,
they're very expensive and they're not
portable or deployable. So what we've
done is take the concept of the Gas
Analysis Package on Beagle 2 and we
built our own 6 centimeter radius mass
spec but one that's affordable and that
can be then taken out to places like
India and China and used to
diagnose people and get them treated
Bedbugs are a massive problem, huge in
places like New York although apparently
New York's only the 18th most popular
spot for bedbugs, I think Boston's the biggest
one
London has a huge problem, hotels in
particular. The one piece of advice I can
give you, if you ever put your suitcase in a
hotel never put it on your bed, put
it on the stand with the
metal straps, that's where you put your suitcase
because they can't climb up the metal
that's why they're there. So we
basically are looking for the
chemicals, so bedbugs communicate
through the signature, you can also find
bedbugs if you see little spotting of blood around
the place and so we look for that as
well. So put into context there are
nearly 600,000 hotel rooms in the
UK, a quarter of them are actually in
London, and nearly 5 million in the US.
But what I didn't realise is that most
hotels are just a brand, a bit like McDonald's or
KFC, they're franchised so actually you
have facility management companies
actually do most of that work
one of which we talked to said well we
let the customers find them for us so
I won't tell you which brand that was
but most of the really big hotels
obviously are taking this very seriously
especially now there is some indication
that bed bugs might be zoonotic vectors
so in other words bed bugs might
transmit disease
up until now has never been thought he
did there's been a study in penn
medicine which suggests that it can
transmit something called Chagas
disease which is a very nasty parasite
which can affect your heart so
increasingly people are becoming more
and more proactive about this
So what I've hopefully shown you today is
that you know space missions mean you've
got to make things small, light, low
power, got to be rugged, shock vibration
proof,
and be able to survive environmental
extremes like on a comet or Mars. If you're
going to build those kind of systems you've got to
build multidisciplinerary teams, you've go to build
partnerships and once you do
that you can then start building new
solutions and new technologies and
eventually develop systems that give you
new opportunities. So Colin is the person who
started me and most of us on that
journey, our journey around the solar
system will continue. As I say the Moon in
2021 but also we're looking for
challenges back here on Earth so if
you've got any ideas about what I can
sniff next then feel free to tell me and
I'll just leave you with one message
which I think it sums up Colin
basically which was, he had a
dream, he put together the team, he had the
belief in us and as Mark has just shown we
probably succeeded.
That's it, thank you.
Thank both very much. That was fantastic and I think
what we've seen is the challenge
around science and technology and to
think of the mission itself as the
end of the story, I think Taff has shown us
that it's very much just the beginning
of the story and where the spin-offs
from what we do from the challenges we
face and the way that we go about
solving those challenges, the spin-offs
from this I think that's where the
imagination really does extend. So we
have a few minutes for some questions, we
have a roving microphone because if you
don't use the microphone we won't
capture it on the streaming
and I'll also ask Mark and Taff to come
up here again to use the microphone to
answer any questions. So would anybody
care to raise a question and Thom has the
microphone down here. Let's do it nice and
close.
I saw that there was the logo of Rothamsted Research on one of the
partnerships
and I was just
wondering what the the project
on that one is?
Well that particular project was to look at
something called the bluetongue
virus which is a zoonotic vector that
affects sheep and
starting to affect sheep in the UK
because global warming is meaning that the
UK is getting warmer, insects
that didn't bite in the UK are now
moving further and further north so
Rothamsted and Pirbright Institute and
also London School of
Hygiene and Tropical Medicine so
James Logan who was in the video was
also part of the project and the idea
was could we smell the
sheep to then try and work out that they've
been infected so were they
producing different volatile
compounds.
Any other questions?
A question for Professor Sims
In regard to
the Schiaparelli probe I happened to see a
picture of it it seemed quite similar to
the Beagle in terms of that watch case
design, is that
something that Beagle 2
has brought to space science, in that
approach to lander design?
In some aspects yes, in most landers you want a compact shape
they tend to be round in
some cases, Schiaparelli was a bit bigger
had more mass, different landing technique, it used
retro rockets and then would have
crashed down on the surface, so yes to
some extent Beagle 2 has influenced
things but those influences were there I
think before Beagle 2 started. Schiaparelli
wouldn't have unfolded, it would
rely on his batteries, it would have worked for
a few days, I feel very sad for the team
they put a lot of effort in, like the Beagle 2
team so tragedy for them and a tragedy
that they didn't get any data.
I guess this is one for Professor Sims
In passing you mentioned the need
to provide biosecurity on probes going
to Mars, could you enlarge on that a bit
because I know it makes the
whole thing much more difficult.
It certainly does, your not wantonly allowed
to contaminate another planet
it goes under the name of planetary
protection, it's an old UN treaty which has
been there since the late 1950's
in actual fact and you need to
sterilise your spacecraft for two
reasons: one, not to contaminate your target
but also not to get false positives from
life you may have taken to Mars in the
first place. In the Viking days, back in
the 1960-70s, when vulves were
used in good technology like that which
unfortunately i'm old enough to remember
you could put your whole spacecraft in
another and cook it for 5 days and
sterilise any life-forms on it, nowadays
with modern technology you can't do that
so you tend to sterilise the components
and then put the spacecraft together in an
aseptic or sterile facility. And for
Beagle 2 a special facility was built at
the Open University for putting Beagle 2
together and you have to actually do
microbial monitoring of your staff as
well. Unfortunately some of us
actually have larger microbial loads
than others and some people have to
shave their beards off to stop
generating microbes which potentially
would contaminate Beagle 2. So lots of
complications there in terms of
sterilising spacecraft, getting it to launch
pad, keeping its sterile and
operating it on Mars.
I remember seeing Daz's fingerprints and
Judith collecting a plate and it was disgusting.
If you take a typical coin out of your pocket there'll
be tens of bacteria spores on it before
sterilisation and you have to clean your
spacecraft to an alarming degree, essentially
you have to do a million-fold reduction in the
number of bacteria typically or more.
Hi my name is Des, I used to be a
physics teacher and I'm old enough to
remember the Viking landings, I was
very young at the time, and I'm
curious really about all these different
Mars landings that have happened over the
decades and from the
outsider's perspective all seems a bit
random but is there a progression
or are they all
competing with one another, how does it all work?
They all seem to be doing similar
things and yet different things, educate us
I think you've hit it on the head, they are
doing similar things but different
things, certainly NASA
has a programme of Mars landers now, it
lost interest in Mars after Viking and
didn't go back until 1997
in Pathfinder and that's progressed through
everything to Curiosity we see today.
Beagle 2 was at the time was a once-off
opportunity for Europe to get to Mars to
do its own science use its own
instruments and that's now morphed into
the Aurora programme and the rover that will
go hopefully in 2020 assuming it's
funded, there's a meeting going on next week
which will decide its funding, It's a bit
of competition and lots of
collaboration as well, science is
international, people don't necessarily
do the same thing they would do slightly
different things, they will go to
different landing sites there's lots of
places on Mars we'd like to go to
unfortunately some of the more
interesting ones of the very difficult
ones to get to. The
surface area of Mars is the about equivalent
land area of the Earth, so pick a site on
Earth where do you
go? Lots of places on Mars to go,
lots of places to explore and all that
constant question was their life there
or even did life start there and was
transferred to Earth and so we might be
the remnants, as some wag said, Martian
pond ***.
So this would be a question for
Professor Sims, was there a
specific ESA bid for a lander to go
on Mars Express or did your team
just spontaneously come up with
a crazy idea and ran to ESA and say
please put this on Mars because you've made
it sound quite improbable so I'm
guessing there was a proposal there already
There wasn't a proposal in the
beginning of 1997 there was Colin's idea
to put a lander on it I think it's fair
to say ESA thought a lander was a
complication too much. Despite some
attempted discouragement we put together
a bid which went to ESA in 1998 and
Beagle 2 got selected, everybody
realised that putting a lander on Mars was
important, it would do unique science, it
would complement the observations from
Mars Express from orbit and as they
say the rest is history. We got it there,
we launched it but certainly back in
1996 ESA
started dreaming of Mars Express, they
didn't consider a lander, they thought it was a
complication too much.
I have a question for Professor
Sims, so since there are so many Mars
landers already working on Mars,
is it possible that other rovers
can rescue Beagle 2 and bring it back
to life?
I wish, unfortunately they're thousands
of kilometres away so even at top speed
they would take a while to get there, it is
probably a great understatement.
It would be nice to think you could
drive over and push the panel open and
Beagle 2 would work, unfortunately
that won't happen, I suspect
maybe one day, in 20-30 years time, perhaps even
longer in the future maybe somebody will
walk up to the side of Beagle 2, and examine
Beagle 2 but unfortunately not. It would
be great to rescue it but practicalities
of Mars missions means that's impossible.
Thank you, probably just to have a nice
conversation with NASA.
We'll take one more, down here
Hello this is a question for Professor
Sims, were there any specific advancements
in the electronics for Beagle 2?
Yes, you're taxing my memory now. Certainly it was a
very low powered microprocessor,
it was a state-of-the-art microprocessor
the type has eluded
me at the moment but may come back. It
was a very low power system, it was designed
to operate on 10 to 20 watts typically
with peak power on some of the instruments
going up to 30 watts. At the time it was
state-of-the-art solar arrays, gallium
arsenide arrays, three-layer arrays I
think to get the maximum power. You find
a lot of this in the Beagle 2 books
that Colin published. Software was
quite novel and it was two different
software systems, one for entry and descent
and then a multitasking system for the
surface operations.
What we do know from the images of
Beagle 2 is that that switchover happened
because the deployment started. We
actually reloaded all the software on
the way to Mars, something that is
not recommended but we did because we were
pushing the time limit for preparing
Beagle 2, as we operated Beagle 2 we
found all sorts of software patches they
got to a ridiculous stage where we
decided we'd bite the bullet and reload
all the software on the way to Mars
something which is not recommended but
it did work and we did
succeed, we know from the commands and
telemetry that software was uploaded and
we now know from the images it did work
because the deployment did start.
Thank you
Good, thank you everybody
It falls to me just to bring things to a
close this evening and I wanted to
firstly acknowledge Mark and Taff for the
the talks that they have given us this
evening and I'm sure you'll join me in
doing that.
Taff, dogs can smell cancer they can also
smell truffles
so if you ever developed something that
will detect truffles I'll happily help
you test that.
I'd also like to thank Judith and Colin's family for
creating this opportunity for us all, for
supporting this, and we will be looking
forward to the third Colin Pillinger
memorial lecture next year so I'd also
like to acknowledge all of the support
that we've had from the family in
allowing us to do this
And finally I think looking
back on this as I said this was an area
that has always interested me and
clearly interested a lot of other people
and we heard from Mark how the
challenges that the Beagle mission
faced and we talked about success and
failure and I think I do wonder if
success and failure are the right words here
at all, I think really success is
the right word here and I think going
forward in terms of looking at what
other people have done one of the things
I am reminded of here is I think a quote
from Isaac Newton which is that if
I have seen further it is by standing on
the shoulders of giants
if we don't take challenges and meet
challenges head-on we never progress and
progress inevitably comes with
challenges and the overcoming of those
challenges I think we've seen that whole
story exemplified here this evening so
again I think this goes back to one of
the Giants and I think that's who we
should acknowledge finally this evening,
Colin Pillinger.
Good so thank you everybody for coming
have a safe journey home, until next year.
