Hi Sandy, I am working with a group of educators at CASM. May they all log
on with our ID and password?
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:01AM PDT (-0700 GMT)
Central Michigan Math. & Sci. Center: NO!!! I only have room for 25
usernames/passwords in the chat room! Pick one or two folks to type in the
questions. Otherwise the chatroom will be flooded. Thanks very much :-)
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:04AM PDT

OK. Thanks.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:03AM PDT (-0700 GMT)
Central Michigan Math. & Sci. Center: There are already 25 folks
registered for this chat. That's the reason why I can't let everyone in
your group participate.
Catherin/Victoria, BC: . . . . Mon, Aug 18, 10:00AM PDT (-0700 GMT)
Hi All... I'm glad to be here!
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:02AM PDT (-0700 GMT)
Hello Catherin. Glad you made it to our chat today!
Scott/Moore: . . . . Mon, Aug 18, 10:04AM PDT (-0700 GMT)
Hello Mike and Sandy.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:05AM PDT (-0700 GMT)
Welcome Scott: We'll be starting momentarily...
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:06AM PDT (-0700 GMT)
EVERYONE: WELCOME to today's chat with Mike Mellon! Mike is a planetary
geologist. His work focuses primarily on studying martian geology and
climate, including, as a central link between these two, water. In his
work, Mike investigates where water on Mars could be located and what
geologic evidence can tell us about the planetwide distribution of water.
Mike also studies how water is related to the martian climate and how the
climate changes over time.
Mike, UC Boulder: . . . . Mon, Aug 18, 10:07AM PDT (-0700 GMT)
Hi everyone! I'm here now and ready to answer questions.
Catherin/Victoria,: . . . . Mon, Aug 18, 10:02AM PDT (-0700 GMT)
If I was to arrive on Mars with a container of H2O, and pour the contents
to the ground, what would happen? Would the water vapourize, pool on the
ground, freeze? sink into the sand?
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:03AM PDT
(-0700 GMT)
Is there erosion on mars now. How often does it turn the regoligth over?
Does it sculpt rocks?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:10AM PDT (-0700 GMT)
Central Michigan: There is going to be some erosion on Mars caused by wind
blown sand and frost, but the rate is unknown at this time. It is probably
much lower than on Earth.
Mike, UC Boulder: . . . . Mon, Aug 18, 10:11AM PDT (-0700 GMT)
Central Michigan: As for turning over the regolith, meteorite impacts are
probably much more efficient. This process is called impact gardening.
Mike, UC Boulder: . . . . Mon, Aug 18, 10:13AM PDT (-0700 GMT)
Central Michigan: Sculpting rocks is possible, particularly from the
windblown sand. Some scientists have suggested that the small holes and
rocks we see on surface rocks could have been caused by this process.
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:06AM PDT
(-0700 GMT)
Are there visible micometerorite impacts being found on the rocks
examined. Are glass spheres being found in the soil?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:26AM PDT (-0700 GMT)
Central Michigan: The image resolution of cameras on the mars surface is
not good enough to find micrometeorite impacts. However, the atmosphere,
as thin as it is, is thick enough to slow very small meteors so they would
not cause much damage to the surface.
Catherin/Victoria,: . . . . Mon, Aug 18, 10:06AM PDT (-0700 GMT)
I've heard that comets disperse H2O into Earth's atmosphere. Is this
enough to change the apparent constant volume of water on the Earth over
time?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:16AM PDT (-0700 GMT)
Catherin: The addition of water to the Earth (or any planet) by comets is
a new topic of debate among scientists. Previously we thought that the
water on the surface of the Earth came from its interior. Now it may be
that some of much of the water has come from comets. How much exactly it
still being studied.
Ehor, Edmonton: . . . . Mon, Aug 18, 10:06AM PDT (-0700 GMT)
Does Mars have a magnetic pole like earth?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:18AM PDT (-0700 GMT)
Ehor: The magnetic field of Mars is extremely weak at best, unlike Earth's
which is relatively strong. It may be that the small magnetic field we do
measure at Mars is do to the surface rocks, instead of originating at the
core like Earth. We need to send more sensitive instruments to Mars to
better understand this.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:22AM PDT (-0700
GMT)
Ehor, I'm from Edmonton too!!!
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:07AM PDT
(-0700 GMT)
Is the water potable on Mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:20AM PDT (-0700 GMT)
Central Michigan: All the water on the surface of Mars right now is
frozen. If you melt it it might be a bit too salty to drink, and is likely
to contain lots of dust. If the salt is not too concentrated, it could be
filtered.
Mike. Haines Middle school: . . . . Mon, Aug 18, 10:08AM PDT (-0700
GMT)
Hi
Scott/Moore: . . . . Mon, Aug 18, 10:08AM PDT (-0700 GMT)
Someone just asked what would happen to a glass of water poured on the
Mars surface. I calculated that at 6-8 miilibars pressure, water would
boil at minus 20 Fahrenheit. Is this close? I have noticed that some days
the temperature does reach above minus 20 F, so then the water would boil
off.
Mike, UC Boulder: . . . . Mon, Aug 18, 10:24AM PDT (-0700 GMT)
Scott: Yes, the glass of water would boil then just evaporate off as it
was freezing. Weird huh. The mars atmosphere is very dry and even at the
warmer temperatures the water would not remain.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:11AM PDT (-0700
GMT)
Does any of the other rocks have quartz like Barnacle Bill?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:29AM PDT (-0700 GMT)
Stephanie: I don't know about quartz in the rocks at the Pathfinder
landing site. The only place I know to find late breaking information like
that is the Pathfinder web page.
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:12AM PDT
(-0700 GMT)
Sandy, May I change the name of our group? It should read Capital Area
Math and Sci. Center.
roger/elgin: . . . . Mon, Aug 18, 10:13AM PDT (-0700 GMT)
What are the temperature extremes on the planet?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:31AM PDT (-0700 GMT).
Roger: The average temperature on Mars is -70 degrees centegrade. The
extremes are about -125 centegrade at the poles at night (cold enough to
start condensing some of the atmospheric carbon dioxide). And at the
equator at noon in the summer it can get up to about 30 centegrade. These
are ground temperatures. The atmosphere can be a little warmer of colder.
Bojan: . . . . Mon, Aug 18, 10:13AM PDT (-0700 GMT)
Good day!
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:14AM PDT
(-0700 GMT)
Mike, How did they know that the "Martian" Meteorite found on earth with
evidence of life on Mars, was from Mars?
Ehor, Edmonton: . . . . Mon, Aug 18, 10:14AM PDT (-0700 GMT)
Previous earth based measurements seemed to indicate that Mars emits more
heat than it receives from the sun, has this been verified? If there is
extra heat, where does it come from?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:33AM PDT (-0700 GMT)
Ehor: I have not heard before that Mars emits more energy than it
receives. If it does it would be very little and it would come from the
deep interior of the planet. Currently I don't think our measurements are
good enough to detect it.
Bojan: . . . . Mon, Aug 18, 10:15AM PDT (-0700 GMT)
What are the biggest differences between Earth rocks and Mars rocks?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:34AM PDT (-0700 GMT)
Bojan: The biggest difference between Earth rocks and Mars rocks are that
Mars rocks are on Mars. So far they seem rather similar.
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:16AM PDT
(-0700 GMT)
Mars, Do the polar "ice caps" show change with the seasons?
Scott/Moore: . . . . Mon, Aug 18, 10:16AM PDT (-0700 GMT)
Regarding the atmospheric pressure on the surface, current readings
indicate a dialy cycle between 6.5 millibars and 6.9 millibars. A 1976
Viking report had indicated 7.7 millibars. Is this a significant change
over 21 years? Is this a gradual change or just temporary?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:36AM PDT (-0700 GMT)
Scott: The Viking pressure measurements are from different altitudes on
Mars, accounting for some of the pressure difference. Also there is a
large seasonal cycle. It's too soon to say if there is a long-term trend.
Catherin/Victoria,: . . . . Mon, Aug 18, 10:16AM PDT (-0700 GMT)
What are those bright white areas at the top of twin peaks. re:
super-res-1.jpg?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:38AM PDT (-0700 GMT)
Catherin: I don't about the specific image. I have heard a suggestion that
the bright areas on the "twin peaks" on Mars are some sort of frost, but I
don't believe that because it is just too warm and dry at the landing
site. It is most likely a bright colored rock or soil.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:17AM PDT (-0700
GMT)
Where is the rover now? About how many degrees angle is the 18 metre hill
that Sojourner will climb?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:40AM PDT (-0700 GMT)
Stephanie: The rover has been operating on the west side of the
spacecraft. I don't have any information about the plans for climbing an
18-meter hill.
mike.: . . . . Mon, Aug 18, 10:18AM PDT (-0700 GMT)
are liquids solids in space
Mike, UC Boulder: . . . . Mon, Aug 18, 10:42AM PDT (-0700 GMT)
Mike: Whether something is liquid or solid mainly depends on the
temperature. Whether it is stable depends also on the pressure. Water in
space could be a liquid but it will rapidly evaporate and freeze.
Catherin/Victoria,: . . . . Mon, Aug 18, 10:19AM PDT (-0700 GMT)
If we sent a robot to a comet would we learn more about water?
Scott/Moore: . . . . Mon, Aug 18, 10:22AM PDT (-0700 GMT)
You say that the water is frozen. At the low pressure, does it sublime
when heated?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:44AM PDT (-0700 GMT)
Scott: Frozen water on Mars will sublime if the air is dry enough. If it
is heated it will sublime faster. Keep in mind that the 6 millibar
pressure on Mars is mostly carbon dioxide. There is very little water
vapor.
Tim M/Elgin: . . . . Mon, Aug 18, 10:22AM PDT (-0700 GMT)
Hi Sandy and Mike - We're a group of teachers from Elgin, IL participating
in a technology workshop. We appreciate the chance to join in this
session.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:42AM PDT (-0700 GMT)
WELCOME Tim M and your group of teachers in Elgin. We're glad you could
make it today :-)
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:22AM PDT
(-0700 GMT)
Mike, When is the most likely year for a human mission to mars? Would you
like to go? What type of expertise would the Astronauts have to have? What
experiments would you like to see done by astronauts on mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:47AM PDT (-0700 GMT)
Central Michigan: Given current NASA funding levels, it will be many years
before we go to Mars. I think we will eventually go, but we need to go
back to the moon and permanently in earth orbit first. Do I want to go? I
don't know. Yes for the eventure, but no for the isolation, I guess.
Mike, UC Boulder: . . . . Mon, Aug 18, 10:49AM PDT (-0700 GMT)
Central Michigan: Since I study permafrost on Mars I would like to see
mars astronauts study the surface geology and ground ice. Maybe measuring
subsurface temperatures would be a good first step.
Catherin/Victoria,: . . . . Mon, Aug 18, 10:22AM PDT (-0700 GMT)
What can the rocks at the landing sight tell us about the salinity of the
floods?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:50AM PDT (-0700 GMT)
Catherin: The floods were a very long time ago on Mars and the condition
of the salts on the rocks and in the soil is porbably a reflection ofmore
recent geologic events, such as recent climate cycles. That's my opinion.
Ehor, Edmonton: . . . . Mon, Aug 18, 10:23AM PDT (-0700 GMT)
Awhile back I read a book by Immanuel Velikovsky "Worlds in Collision" who
tried to connect ancient disaster legends with cosmic events. From his
work, he deduced that Venus was a passing comet that colided with Mars.
This caused Mars to orbit so close to earth, that an exchange of gasses
may have occurred. Velikovsky surmised that if this indeed did happen, a
study of the composition of rare gasses (Ar,Ne,Xe,He,Kr) on both planets
should either confirm or deny that such an exchange did occur. Any
thoughts of looking into this from the current Mars site, or future ones?
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:24AM PDT
(-0700 GMT)
Mike, Wouldn't the salt in water leach out as it freezes?
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:24AM PDT (-0700 GMT)
EVERYONE: PLEASE SLOW DOWN ON SENDING QUESTIONS FOR ABOUT 5 MINUTES SO
THAT MIKE CAN ANSWER YOUR QUESTIONS THOROUGLY... THANKS :-)
Belding Beagles: . . . . Mon, Aug 18, 10:24AM PDT (-0700 GMT)
Has Pathfinder been able to find any bodies of water, even
a puddle?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:52AM PDT (-0700 GMT)
Beagles: There is no liquid water at the surface of Mars at the Pathfinder
landing site. Not even a puddle. There should be no liquyid water at the
martian surface anywhere on the planet. it is just too cold and dry.
Keith, UBC: . . . . Mon, Aug 18, 10:27AM PDT (-0700 GMT)
Do you think the focus of the MGS camera system will be stable enough to
allow the accurate prediction of the point spread functions for image
deconvolution?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:54AM PDT (-0700 GMT)
Keith: I not am image processing expert. I don't even understand all of
your question.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:55AM PDT (-0700 GMT)
Keith/UBC: Why don't you submit this question to the "Live From Mars"
Question & Answer section. Go to http://quest.arc.nasa.gov and click on
the Question Mark icon and follow the directions.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:29AM PDT (-0700
GMT)
I've read that the Pathfinder team has a map of Ares Vallis in the
hallway, and you've put your names by where you think Pathfinder would
land, who won?
Bojan: . . . . Mon, Aug 18, 10:29AM PDT (-0700 GMT)
In what ways is the erosion on Mars different from one on Earth?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:56AM PDT (-0700 GMT)
Bojan: Erosion on Mars differs from Earth mainly in that Mars presently
lacks liquid water. Liquid water on Earth is an extremely powerful
erosional agent and so Martian erosion is much slower due only to wind and
impacts.
Central Michigan Math. & Sci. Center: . . . . Mon, Aug 18, 10:29AM PDT
(-0700 GMT)
Mike, How much longer will Pathfinder be active?
Catherin/Victoria, BC, Canada: . . . . Mon, Aug 18, 10:32AM PDT (-0700
GMT)
In the next 20 years, if we had the will and the $$, could we build an
environment on Mars in which humans could live?
glencliff: . . . . Mon, Aug 18, 10:32AM PDT (-0700 GMT)
Hi, Mike-I lived in NJ once (Medford Lakes). What was your home town?
Mrs. T
Mike, UC Boulder: . . . . Mon, Aug 18, 10:53AM PDT (-0700 GMT)
Glencliff: I grew up in Medford, NJ. Howdy neighbour.
Belding: . . . . Mon, Aug 18, 10:35AM PDT (-0700 GMT)
Hello, Mike...Are there any resources found in the soil on Mars that would
possibly be productive for Earth?
Mike, UC Boulder: . . . . Mon, Aug 18, 10:59AM PDT (-0700 GMT)
Belding: There may be many of the same mineral resources on Mars that we
find on Earth. To know the concentration and distribution we will need to
wait for the Mars GLobal Surveyor spacecraft which is due to arrive in a
month or so. On the other hand water is probably the most important
resource if we go to mars.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:36AM PDT (-0700 GMT)
EVERYONE: MIKE IS STILL TRYING TO PLAY CATCH UP! WE ARE ONLY ONE QUESTION
45 AND YOU ARE UP TO 76...slow down...
Catherin/Victoria, BC, Canada: . . . . Mon, Aug 18, 10:45AM PDT (-0700
GMT)
But I have lists of questions! And each answer adds to it. :-}
What's a planet nut to do??
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:41AM PDT (-0700
GMT)
Sandy, perhaps you should only let 10 to 15 people register.
Mike.: . . . . Mon, Aug 18, 10:40AM PDT (-0700 GMT)
Do you want to go to mars or the moon.
Scott/Moore: . . . . Mon, Aug 18, 10:42AM PDT (-0700 GMT)
Thanks for the responses, Mike. I appreciate the answers.
James/Glencliff: . . . . Mon, Aug 18, 10:44AM PDT (-0700 GMT)
How much was the budget on the Mars Pathfinder?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:00AM PDT (-0700 GMT)
James/Glencliff: I'm not sure exactly howmuch Pathfinder cost, but it was
actually quite low relative to other past missions. NASA is trying to send
smaller cheaper missions.
Irene/Elgin: . . . . Mon, Aug 18, 10:45AM PDT (-0700 GMT)
Is there any evidence that would show that a plant from Earth could live
or grow in the soil from Mars?
glencliff: . . . . Mon, Aug 18, 10:46AM PDT (-0700 GMT)
Sandy- we're having trouble reading our answers. Are we
getting through? Suggested refresh rate? Mrs T
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 10:51AM PDT (-0700 GMT)
glencliff: You're not having trouble reading your answers, because we
haven't yet got to one of your questions. There are so many good ones
today. We'll get to you soon!
Irene/Elgin: . . . . Mon, Aug 18, 10:46AM PDT (-0700 GMT)
Is there any evidence that would show that a plant from Earth could live
or grow in the soil from Mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:02AM PDT (-0700 GMT)
Irene/Elgin: The soil at the surface of Mars lacks many of the organic
nutrients that is in Earths soil. Only a few types of plants can make
their own nutrients under these conditions.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 10:48AM PDT (-0700
GMT)
When the rover was doing it's wheel test, why was the soil white under?
Any idea of what's it's made of?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:05AM PDT (-0700 GMT)
Stephanie: The white soil under the rover wheels is a mystery to us. I
have had many discussions with colleagues about it. Some possibilities are
that soil has a higher salt content or is finer particles.
Bojan: . . . . Mon, Aug 18, 10:50AM PDT (-0700 GMT)
How big are the underground reservoirs and is there any possibility of
underground rivers on Mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:10AM PDT (-0700 GMT)
Bojan: Yes there is a possibility of underground rivers on Mars. It is
warm enough deep down in the subsurface, but it is not known if there is
enough water to fill these possible reserviors, nor have they been
measured in any way.
Irene/Elgin: . . . . Mon, Aug 18, 10:50AM PDT (-0700 GMT)
Is there any evidence that would show that a plant from Earth could live
or grow in the soil from Mars?
Brian/homeschool: . . . . Mon, Aug 18, 10:51AM PDT (-0700 GMT)
Is there anything productive to Earth that has been found on Mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:07AM PDT (-0700 GMT)
Brian/Homeschool: The most productive thing on Mars so far is learning
about its climate, which helps us tremendously with learning about Earth's
climate. We have a long water to go to find mineral or other resources,
but that's a matter of time.
Mike.Haines Middle school: . . . . Mon, Aug 18, 10:54AM PDT (-0700
GMT)
Do you have any pets?
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 11:00AM PDT (-0700 GMT)
EVERYONE: MIKE HAS GRACIOUSLY OFFERED TO STAY ON FOR AN EXTRA 15-20
MINUTES TO ANSWER ALL OF YOUR FANTASTIC QUESTIONS. BUT PLEASE slow down...
thanks :-)
Steven/homeschool: . . . . Mon, Aug 18, 11:02AM PDT (-0700 GMT)
Is there any evidence of fossils on Mars?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:09AM PDT (-0700 GMT)
Steven/Homeshool: We have not found evidence of fossils on Mars, but we
have not yet looked. The recent interest in looking for fossils is only
now influencing the long term mission planning for Mars and space craft to
look for fossils will come a few years down the road.
Stephanie/wongtong@connect.ab.ca: . . . . Mon, Aug 18, 11:07AM PDT (-0700
GMT)
Sandy, too bad I can't stay any longer. I'll read the rest
of the answers later. Goodbye Sandy and Mike!
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 11:10AM PDT (-0700 GMT)
Goodbye Stephanie: Your questions were great! Thanks for joining us today!

Brian/homeschool: . . . . Mon, Aug 18, 11:11AM PDT (-0700 GMT)
Are there clouds in the Mars atmosphere?
Mike, UC Boulder: . . . . Mon, Aug 18, 11:13AM PDT (-0700 GMT)
Brian/homeschool: Yes there are clouds in the mars atmosphere. Some of
them are water ice clouds and sometimes there are also carbon dioxide ice
clouds.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 11:11AM PDT (-0700 GMT)
EVERYONE: It looks like we've caught and answered most everyone's
questions. So I suppose we should let Mike get back to what he does the
best! Thanks for joining us today and putting up with the time delay in
answering your questions. There were far more than we had anticipated.
This chat will be archived later this week.
Mike, UC Boulder: . . . . Mon, Aug 18, 11:11AM PDT (-0700 GMT)
Thanks everyone. Those were a lot of good and thoughtful (and some
difficult) questions. Hope to chat with you all again sometime.
Sandy/NASA Chat Host: . . . . Mon, Aug 18, 11:12AM PDT (-0700 GMT)
Mike: Thanks so much for all the time you spent with us today! You
answered some pretty tough questions :-) We look forward to chatting with
you again in the future!
Brian/homeschool: . . . . Mon, Aug 18, 11:13AM PDT (-0700 GMT)
Thanks for your time, Mike! We had fun! Thanks Sandy, for the
organizational skills you afforded for us! =o)
