Today's "Live From Mars" Web chat with Greg Wilson from NASA's Ames
Research Center will begin in about 45 minutes-- 10:30 a.m., PDT... See
you soon!
[ Shellie 10:14:50 ]
Hello out there!
[ Sandy/NASAChatHost 10:15:56 ]
Good
Morning Shellie! We'll begin in about 15 minutes. Where are you from?
[ Cindy 10:21:32 ]
I am seeing if we are logged on at the time.
We have our questions ready.
[ Sandy/NASAChatHost 10:24:25 ]
Hi
Cindy: I see you! Glad you have questions ready. The chat will begin in
the next 5-10 mins. Greg is running a few minutes late...
[ MrSmith 10:31:19 ]
Mr.Smith's class is from Corry
Pennsylvania and is in 8th grade.
[ Sandy/NASAChatHost 10:34:10

RE: [CorryMiddleSchool] We are ready to
go!
Welcome Corry Middle School! We will begin momentarily!
[ Hockaday6thperiodMrsP - 30 - 10:34:37 ]
I am in Dallas and
want to welcome Dr. Wilson to our classroom. I am Emily. My question to
you is - we have read about wind sensors on Mars measuring the wind speed,
do you also use these for major storms on mars?
[ Sandy/NASAChatHost 10:35:14
]
RE: [Lucy] We are here in Sioux Center
Middle School ready to meet Greg Wilson.
Hi Lucy and the Sioux
Center Middle School! We'll begin shortly!
[ MrSmith 10:36:49 ]
Is there sedimentary rock on Mars?
[ Hockaday6thperiodMrsP 10:37:24 ]
Hi Dr. Wilson my name is
Mallory Owen. What are some of the similarities and differences of the
particles on earth and on Mars that are blown by the wind?
[ GregWilson/Geologist 11:39:07
]
Mallory -- Particles on Mars are formed only by abrasion. On Earth,
sand comes form chemical weathering of granite.
[ CorryMiddleSchool 10:37:36 ]
What was going through your mind
Doctor Wilson when you recieved the first data from the pathfinder?
[ Lealac/DanburyHS 10:38:07 ]
Almost time? We have interesting
questions to get answered.
[ Hockaday6thperiodMrsP 10:38:54 ]
HI! I'm Megha Agrawal. What
do you like best about your job and why?
[ GregWilson/Geologist 11:40:22
]
Megha - I like working with people... the challenge of landing on
Mars and the friendships you make with the people you work with are the
BEST!!!!!!
[ Rebecca 10:39:55 ]
Hi, Encinal School is logging on.
[ Hockaday7thgradeSarah 10:40:04 ]
What do you think is the
best geological breakthrough on Mars, in your area of expertise?
[ GregWilson/Geologist 11:41:03
]
Sarah -- One that has been made...or needs to be made??? Great
question! :-)
[ Lucy 10:41:13 ]
We'd also like to know what is used for
determining wind at the Sagan Memorial Station and how it works and what
has been the average speed and direction of the wind? Would the wind ever
get so strong it could blow the Sojourner over?
[ Lealac/DanburyHS 10:41:23 ]
Will this mission lead in any way
to a manned exploration of Mars?
[ GregWilson/Geologist
11:41:03]
Lealac -- We think so. I know more about the conditions in
the tunnel then I do about mars...that is way we go there. But I can't
simulate the low temperatures....I am working on that!
[ KeystonesOaksHS 10:43:01 ]
We are honored to have this
oppertunity to have the question- answer period with you. Our school has
questions and will be joining in momentarily.
[ Sandy/NASAChatHost 10:45:09 ]
Greg
Wilson is a planetary geologist working at NASA's Ames Research Center in
Mountain View, California. Greg is primarily responsible for conducting
geologic research in the Mars and Venus wind tunnels and has also done a
lot of work in support of the Mars Pathfinder mission. Today he will give
us an update on the Mars Pathfinder meteorology experiment.
[ GregWilson/Geologist 10:45:46 ]
Hi
everyone... Sorry I am late... :-)
[ Hockaday7thgradeTiffany 10:42:25 ]
What data and information
have you collected from performing tests with the wind tunnels?
[ GregWilson/Geologist 10:47:17
]
Tiffany - we do a lot of wind erosion research...like what wind
speeds are needed to move dust on mars. Plus we do testing of
intruments like the windsocks on Mars Pathfinder.
[ GregWilson/Geologist 10:48:28
]
RE: [Lealac/DanburyHS] Greg, do the
simulations in wind tunnels accurately predict the conditions on
Mars?
It does everything except the temperature.
[ GregWilson/Geologist 10:49:16
]
RE: [KeystonesOaksHS] If the core of mars
is ice, when their was volcanos what was
erupting?
Keystone: But the core is not made of ice....it may
still be lava or solid!
[ GregWilson/Geologist 10:50:35
]
RE: [Lealac/DanburyHS] Also, to restate my
first question, do you think this mission will lead to a manned mission to
Mars? And what kind of data would lead to these
conclusions?
Lealac: Yes...someday we will need to go to
Mars...but that may take a while.
[ Rebecca 10:51:33 ]
What are you presently doing for geology
research on Mars and Venus?
[ GregWilson/Geologist 10:51:33
]
RE: [Hockaday6thperiodMrsP] Hi my name is
Jamie, and I have a question...Mars the god of war, married Venus, the
goddess of beauty, they had two children: Deimos and Phebos. These two
children were sent to the astroid belt where they stayed for a long time.
So their mother thought of sending her son from Mercury to the astroid
belt also to be with them. As sdoon as her son arrived Deimos and Phebos
were for some reason, heading towards Mars to take orbit around him, so
the lonely son was left in the astroid belt till now waiting for another
miracle to happen in order to go and join his brothers. So who is that
son?
Jamie: You are really testing me...I don't know! I
should have stayed awake in history!
[ Lealac/DanburyHS 10:51:38 ]
How do the applications of
mathematical formulas on earth have to be manipulated to deal with data on
Mars? (i.e. velocity, time,and distance)
[ Hockaday7thgradeMrA 10:52:33 ]
How do you know accurately
what the martian surface is like? Do you simulate Martian surface
conditions in your wind tunnels?
[ Hockaday6thperiodMrsP 10:41:21 ]
Hi, I'm Katy Rogers!! Have
you gotten any results from your wind experiments yet??
[ GregWilson/Geologist 10:52:40
]
Katy: ...Wind sensors....Yes we do...We are hoping to get Pathfinder
back because now is the dust storm season! Yes! I want to understand dust
storms!
[ Hockaday6thperiodMrsP 10:53:16 ]
Hello my name is Marguerite.
Do you support the theory of "the Big Bang" showing how the universe got
started? And my class and I thank you very much for coming to talk to us!
[ Lucy 10:35:55 ]
Is NASA going to try to get the Pathfinder to
respond so we can get more weather information?
[ GregWilson/Geologist 10:53:55
]
Lucy-- we are working really hard at getting pathfinder back...we
will not give up for at least another month, if ever...We really want the
weather data, we have most of the data from the imager and rover, but the
weather is always new!
[ Lucy 10:53:58 ]
We were wondering if you got our question.
What instruments are being used on the Pathfinder to find wind
information. Will we be able to get the info since Pathfinder is no
longer communicating. Is the wind ever strong enough to knock over the
Pathfinder or Sojourner?
[ GregWilson/Geologist 10:58:31
]
Lucy- We have wind sensor and temperature sensors...We measure wind
by looking at heat tranfer from heated wires... When we are not talking to
pathfinder, we don't get any science data... :-( The winds are not very
strong dynamically becasue of the thin atmosphere...no problem for the
rover or lander
[ CorryMiddleSchool 10:54:40 ]
Does Mars have sedimentary
rocks?
[ GregWilson/Geologist 11:38:07
]
Corry -- We think so...still a very debated topic... What do you
think??? What is the evidence?
[ GregWilson/Geologist 10:59:38
]
Corry: MS good question...We hope so...it would show geologic
processes are important...We have found none so far...but some may debate
that.
[ CorryMiddleSchool 10:54:58 ]
What projects are you working on
right now?
[ GregWilson/Geologist 10:55:13
]
RE: [Lealac/DanburyHS] How do the
applications of mathematical formulas on earth have to be manipulated to
deal with data on Mars? (i.e. velocity, time,and
distance)
Lealac: Time, distance are the same. The only real
problem is gravity... which is 1/3 that of earth... But we know a lot
about Mars' gravity so it is not that difficult...did i answer your
question???
[ Hockaday6thperiodMrsP 10:55:40 ]
Hi!!! My name is Christen L.
Since we have hail storms on earth, would the hail freeze on Mars?
[ GregWilson/Geologist 11:00:14
]
Christen: Everything freezes on mars...but interesting question.
[ Carl 10:55:45 ]
Is the data being gathered on the MGS's
spectrometer going to be compared with data from pathfinder.
[ GregWilson/Geologist 11:01:02
]
Carl -- Yes! That is way we sent them at the same time... We would
call this "ground truthing!" We want pathfinder back!!!!!
[ Lealac/DanburyHS - 81 - 10:56:29 ]
Yes, please describe the
insrtuments used to measure wind.
[ Natasha 10:56:34 ]
Do you believe that there is life on Mars?
[ GregWilson/Geologist 11:43:18
]
Natasha -- Sure, why not? Bacteria sure... green men, no way!
Life may not be as rare as we might want to believe.
[ Lucy - 83 - 10:56:38 ]
We know you visited Lesotho, Africa.
What did you do there and what is it like there?
[ GregWilson/Geologist 11:02:18
]
Lucy -- Thanks for asking... I helped them develop irrigation
systems for small farms and helped them conserve the soil... I loved it!
They are wonderful friendly people... I miss them alot!
[ GregWilson/Geologist 10:56:40
]
RE: [Hockaday7thgradeMrA] How do you know
accurately what the martian surface is like? Do you simulate Martian
surface conditions in your wind tunnels?
Hockaday: We simulate
what is called surface roughness....It is pretty complicated but it causes
the same amount of wind shear on the wind tunnel and what we think the
wind shear is on Mars.
[ Lealac/DanburyHS - 85 - 10:58:09 ]
How does this mission
compare with the Viking probe of Mars of earlier decades?
[ Lealac/DanburyHS10:59:30 ]
How does the erosion of the
surface become affected by the gravitational difference on Mars?
[ Hockaday7thgradeKelliCaroline10:59:49 ]
Does Mars have large
areas of sand dunes like Earth's deserts?
[ TylerfromEncinalSchool 10:59:53 ]
What will you do when you
have finished studies on Mars and Venus?
[ GregWilson/Geologist 11:03:30
]
Tyler-- I hope that everything I learn in the next couple of years
gives me more questions to answer... We don't know everything about Earth,
so I guess it will be a long time before we learn everything about Mars,
Venus...etc :-)!!!
[ Hockaday6thperiodMrsP - 92 - 11:00:16 ]
Hi, Dr Wilson, I am
Elizabeth. What do you do before the mission to prepare yourself?
[ GregWilson/Geologist 11:04:49
]
Elizabeth-- You practice the mission over and over again in
simulations...tests! We did 7 for Pathfinder, the the mission way
referred to operational readyness test #8! and get a lot of sleep! :-)
[ CorryMiddleSchool 11:01:23 ]
Who got the original idea of the
Mars Pathinder?
[ Hockaday7thgradeTess 11:01:55 ]
If Mars doesn't have linear
sand dunes, what kind of sand dunes does it have, and what makes a linear
dune linear??
[ GregWilson/Geologist 11:06:35
]
Tess -- The wind makes it linear... Mars has simple sand dunes called
barcan dunes...crescent shaped... The wind blows the sand from one side to
the other... Linear dunes require a more complex wind and the simple
dunes.
[ CorryMiddleSchool 11:02:01 ]
Will we ever send a probe to
Venus?
[ GregWilson/Geologist 11:07:14
]
Corry-- We have sent many probes to Venus...the Russians have even
landed...check it out!
[ MrSmith - 97 - 11:02:11 ]
What first interested you in the
wind of other planets?
[ GregWilson/Geologist 11:10:41
]
Mr. Smith -- The wind of our own planet and the fact that the wind
is active on our planet, and Mars, Venus, and possibly Titan...
[ Hockaday6thperiodMrsP 11:02:15 ]
Hello, I'm Susannah. I have
seen some pictures on the internet that show Mars as being blue. Is this
just picture distortion, or is Mars sometimes blue?
[ GregWilson/Geologist 11:11:47
]
Susannah-- Mars is red... Must be distortion.
[ Carl 11:03:01 ]
Can they use the rover's arm to clean off the
solar panel on the top?
[ GregWilson/Geologist 11:12:37
]
Carl -- Good idea, but it would not work... We do not allow the rover
too close to the lander because it has the potential to do more damage
then help it.
[ Hockaday7thgradeBlake 11:03:46 ]
Hi. I am Blake. I was
wondering, do you know what the fastest wind speed you have recorded from
Mars is?
[ GregWilson/Geologist 11:13:32
]
Blake-- I am just guessing now, because we have not reduce the data
completely... but the dust devil winds are around 25-30 m/s or 40-55
miles per hour.
[ Lucy - 104 - 11:04:37 ]
What kind of wind tunnel experiments
have you done in relation to Saturn's moon, Titan.
[ GregWilson/Geologist 11:14:41
]
Lucy -- None at the moment, but I want too! As we get closer to
Saturn in the next couple of years I will get more motivated to look at
it... The simulations will be closer to what Venus is like than Mars.
[ Hockaday6thperiodMrsP 11:04:51 ]
Hello, my name is Elizabeth
B. Dr. Wilson, I know you specialize in aeolian processes, but what are
some other examples of what you do with wind studies?
[ GregWilson/Geologist 11:16:03
]
Elizebeth B. -- We build and test sensors that will work on Mars...
Dust is also an air-quality issue in this country, so I work on that was
well. Did I answer your question???
[ MrSmith - 107 - 11:05:11 ]
How long until you send humans to
Mars?
[ Hockaday7thgradeHILARY 11:05:59 ]
Is the wind on Mars created
by the same forces as on Earth?
[ GregWilson/Geologist 11:16:45
]
Hilary -- In general yes.... pressure difference and revolving motion
of the Earth...
[ Hockaday6thperiodMrsP 11:10:18 ]
It's 2540 you and your
family live at Valles Marineris Colony you love astronomy and you keep
watching Mars' two beautiful moons. In the summer you left with your
soccer team for an expidition to the South Pole. One night after you
fineshed your work you looked up in the sky, but you could see only one
moon! Where did *____ go?
What is the name of *____. *is the name of a moon
----Jamie
[ GregWilson/Geologist 11:18:07
]
hockaday/Mrs. P/Jamie -- Hmmmm....I will have to think about it... I
know
the moons move really quick... I want to know the answer so I can bug my
Mars friends!!!! :-)
[ Carl 11:10:26 ]
Because there is almost no standing water on
Mars is the dynamic generation of wind diffrent? i.e. no evaporation.
[ GregWilson/Geologist 11:19:37
]
Carl -- Good question.... Winds come mostly from pressure differences
and the corealis forces... Water gives the Earth more complex patterns,
but not that much different.
[ CorryMiddleSchool 11:10:40 ]
Did the pathfinder interfere
with your personal life?
[ GregWilson/Geologist 11:20:32
]
Corry -- Yes! I got 6 hrs sleep a day, worked some 40 days with out
a day off. Forgot my girlfriend's bithday! But it was worth every
minute!
[ Hockaday6thperiodMrsP 11:11:16 ]
Hi!! It's Megha and Katy
again. We're wondering, what is the instrument that you use to measure
Mars' pressure, and how does that instrument do this? Thanks!
[ Lucy11:12:03 ]
As we were discussing what causes wind and
decided our rotation movement is part of the cause we were wondering what
causes a planet to rotate?
[ GregWilson/Geologist 11:21:33
]
Lucy -- Good question... I think it is just the left over angular
momentum from the orginal formation of the solar system... I am not
sure....great question. Let me know if you find out soon! :-)
[ MrSmith 11:12:21 ]
1. How soon do you think we can live on
Mars? 2. How did you feel when all your work payed off?
3. What resources are on Mars? 4. Are there going to be more probes sent
to Mars? 5. Why didn't you make the pathfinder round so it could roll back
over easier?
[ GregWilson/Geologist 11:22:39
]
Mr. smith-- 30 years... that's just me! Lots... Every 2 years we
are sending 2 probes..lander and orbitor, plus other countries like Japan
are sending probes in the next couple of years!
[ Hockaday6thperiodMrsP 11:14:07 ]
Hi, this is Katy again. I
was wondering if you got any results to your experiments yet and what they
were?
[ GregWilson/Geologist 11:44:10
]
Katy -- Yes, we will be publishing them in "Science" next month and
presentations at the meeting in San Franscico in December...stay tuned in!
[ Lealac/DanburyHS 11:15:11 ]
Thank you for giving us your time
to hold this chat session. We, here at Danbury High School, are involved
in an ongoing project following the Mar's mission. Is there an online
source of physical data that we can access. Specifics, such as data
measurement of use in kinetic or dynamics computations?
[ GregWilson/Geologist 11:23:56
]
Lealac -- Hmmmm good question... All our data will be officially
release through the Planetary Data System (PDS) starting in January...As
for dynamic data, I don't know...call the Jet Propulsion Laboratory!
[ Hockaday7thgrade 11:15:41 ]
We have to leave right now.
Thank you so much!! We appreciated your answers and time!! Bye!
-Hockaday 7th grade-6th period of Dallas Tx.
[ KeystonesOaksHS 11:17:08 ]
Hi my name is Erin O'Toole and I
am from Keystone Oaks High School and I have a Question for you. What is
the difference between the Viking camera satellite and MGS?
[ Lucy 11:18:24 ]
What made you want to go into studying wind
and aeolian processes? And what was your reaction when asked to help with
the Pathfinder mission?
[ GregWilson/Geologist 11:25:20
]
Lucy -- In grad school a professor had some good but different
ideas... I am kind of a rebel, so I worked with him on modeling aeolian
process.... I was thrilled when I was selected!!! It was also a reason
for taking this job after grad school.
[ Hockaday6thperiodMrsP 11:18:30 ]
Hi. This is Mrs. P. of the
Dallas school. My students had to go on to another class but I will stay
on until the end. Will you have time to answer any of the back questions
that haven't been answered after time is up? My students love to have me
print up your responses to their questions to have in their notebooks.
Thanks so much for being on line with us today.
[ Hockaday6thperiodMrsP 11:21:20 ]
Well my student who asked
you about the moons left the room. I don't think she knew the answer but
I will ask her tomorrow. She is the one who had the question about the
myth and who the son was.
[ MrSmith 11:21:23 ]
How many years does it take to do what you
do?
[ GregWilson/Geologist 11:26:19
]
Mr. Smith -- 10 years of school, Mars Pathfinder took 3 years...
Our experiments take several years to get all the data needed to write a
publication and solve a problem... Aeolian problem.
[ CorryMiddleSchool 11:22:30 ]
Why did we name Mars, Mars?
[ GregWilson/Geologist 11:26:57
]
Corry -- Mars is the god of war... Other than that, I think we should
call it "red" :-)
[ mike 11:24:12 ]
What are the major geological differences and
composition between Earth and Mars rocks? How do they know when they found
a rock meterorite from Mars in Antarctica?
[ GregWilson/Geologist 11:29:20
]
Mike -- Mars and Earth formed from the same stuff...so most major
compounds are the same... What is different is the ratio of some
isotopes... That ratio is a signature as to were stuff comes from... Mar
m. have to exact isotope ratios as what we measured during the viking
mission in the 70's and that ratio is different from the Earth's! Great
question... Do some more study of this! :-0
[ CorryMiddleSchool 11:24:39 ]
How was your camping trip Doctor
Wilson?
[ GregWilson/Geologist 11:29:59
]
Corry -- It was great... I wish I had time to do it again this year!
I am going to Death Valley tomorrow!
[ Hockaday6thperiodMrsP 11:25:28 ]
I like the way you have
addressed those questions from students who have not worked with the
material before attending a session like this. Looking up the information
before hand saves a lot of time.
[ Lucy 11:25:32 ]
How many sand dunes have you discovered on
Mars? And could the Sojourner ever get stuck in one of them? Have you
named any of the sand dunes? We realize time is almost up. We want to
thank you for givng us your time. We appreciated it.
[ GregWilson/Geologist 11:30:55
]
Lucy -- None... The rover did get slowed down by one during the
mission, so it is a concern...
[ Lealac/DanburyHS11:27:07 ]
Has there been any seismic
activity detected on Mars by your instruments?
[ GregWilson/Geologist 11:32:17
]
Lealac -- Great question... No, but I think that our accelerometers
are sensitive enough to pick up a tremor if it were to occur and we had
them on... We don't turn them on because they use a lot of power. :-)
[ mikefromcranbrook 11:27:31 ]
How much has the wind eroded the
surface of Mars?
[ GregWilson/Geologist 11:33:09
]
Mike -- Good question... We see dunes and things, but very little
abrasion of rocks... It is a mystery I hope to solve!
[ KeystonesOaksHS 11:27:55 ]
Hi I'm sorry but I must of missed
your reply-- I asked what was the difference between the Viking satallite
camera and the MGS?
[ GregWilson/Geologist 11:34:28
]
Keystoneoaks -- MGS has two cameras...wide field and high
resolution... MGS camera is 100 times better... mostly because of the
technology developments in the last 20 years.
[ Sandy/NASAChatHost 11:28:23
]
EVERYONE: GREG CAN STAY ON AN EXTRA 10 MINUTES SO HE WILL TRY AND
ANSWER ALL OF YOUR QUESTIONS FROM THE BEGINNING OF THE CHAT (THE ONES YOU
SENT BEFORE HE ARRIVED IN THE CHAT ROOM...
[ joe/coquille11:28:54 ]
What wind speed on earth is equivalent
to 300 on Mars?
[ CorryMiddleSchool 11:29:17 ]
How old do you think Mars is?
[ CorryMiddleSchool 11:29:24 ]
What new discoveries has
pathfinder come up with?
[ Lealac/DanburyHS 11:30:14 ]
That is great, Sandy. This is
Charlie now, my class has left for the day. Great fun! Keep up the good
work. Will be looking forward to more "chats". :-)
[ joe/coquille 11:30:39 ]
Scientific American has plans this
month for making your own wind tunnel. Are there experiments we could do
to simulate your work in studying sand transport that you could suggest?
[ GregWilson/Geologist 11:35:54
]
Joe -- Yes. Visit: http://cmex

Valley.
[ CorryMiddleSchool 11:32:18 ]
We want to thank you for this
chat and we really enjoyed it. We have to go now.
[ MrSmith - 165 - 11:32:31 ]
Dr.Wilson, thankyou for your time,
this webchat was great.

RE: [KeystonesOaksHS] Mr. Wilson, Keystone
Oaks High school would like to know why you feel that you do not have to
answer our questions. Stephanie Sommer head of outreach 108.
STEPHANIE: GREG IS ANSWERING QUESTIONS AS FAST AS HE CAN! THERE
ARE OVER
162 QUESTIONS IN THE LOG. HANG IN THERE AND WE'LL TRY TO GET TO YOURS. YOU
ARE not BEING IGNORED :-) SORRY FOR THE DELAY!
[ Hockaday6thperiodMrsP:36:42 ]
Politeness should be a matter
of protocol on these chats. You must not realize how many questions have
been asked. Patience is required and a big thank you to someone who is
taking their time to interact with you.
[ Lucy 11:35:56 ]
On the personal side we were wondering what
kind of car you drive, and what is your favorite music group? And since
you like basketball what is your favorite team? We are typical middle
school students who want to know more about YOU.
[ GregWilson/Geologist 11:45:38
]
Lucy -- 4x4 for desert trips... I like lots...Hansen! I am a big
Laker fan... but the Magic days, not now much anymore.. Glad you are
interested... I am not a nerd!
[ lee 11:40:44 ]
How does the sensor on Sojourner detect the
type of rock?
[ GregWilson/Geologist 11:47:01
]
Lee -- Good question! It sends out x-rays, alpha particles, etc...
and it measures what gets absorded and flexed. Each compound/element is
differend in how it obsorbs and reflexs these particles.
[ Sandy/NASAChatHost 11:48:30
]
EVERYONE: IT LOOKS LIKE EVERYONE HAS GONE BACK TO CLASS NOW AS THERE
ARE NO MORE QUESTIONS, AND GREG NEEDS TO GET BACK TO HIS WIND TUNNEL!
THANK YOU SO MUCH FOR ALL OF YOUR FANTASTIC QUESTIONS. And a special thank
you to Greg for spending time with us today!
[ GregWilson/Geologist 11:48:34

RE: [Carl] Sandy - you must have an
interesting job! What was your major?
I have a FANTASTIC job!
When I was in college I majored in Photojournalism. My degree was the
major reason that I got hired to do some really cool jobs: a "mosaicist"
for the Viking Orbiter Imaging Camera that went to Mars in the 1970s. As
the photos came back from the two onboard cameras they were processed and
then handed to me in very large 100-foot long rolls. It was my job to cut
out each image and tape it to an ajoining image as all the photos fit
together like a giant jigsaw puzzle. From there I took a job editing an
employee publication for NASA's Jet Propulsion Laboratory, and then a
40-page quarterly magazine for NASA Headquarters. Then I got my job here
at NASA Ames Research Center, managing the Live From Mars project!
