. [56 ] Hello Everyone! Welcome to the second Mars Team Online WebChat.
Our guest today is Bob Haberle from NASA's Ames Research Center in Mt.View
California. Bob is the atmosphere interdisciplinary scientist-- which
means he studies the atmosphere of Mars so he can better understand the
weather and climate of Mars and why it is so different from Earth. Bob
is a team member on the Mars Global Surveyor mission, which will be launched
the day after tomorrow.
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:01AM PDT (-0700 GMT). .
. [57 ] A NOTE: There are 15 school signed on this morning, so that means
a lot of questions for Bob. You may not see the answer immediately, but
be patient. Bob will be typing his answers as fast as he can.

. [63 ] First question anyone?
aura/CJHS: . . . . Tue, Nov 5, 9:03AM PDT (-0700 GMT). . . [64 ] What
ideas did you contribute to the Mars Global Surveyor?
Joey/CJHS: . . . . Tue, Nov 5, 9:03AM PDT (-0700 GMT). . . [65 ] Do
you believe water could still exist under the surface of mars?
Joey/CJHS: . . . . Tue, Nov 5, 9:03AM PDT (-0700 GMT). . . [66 ] Do
you believe water could still exist under the surface of mars?
chris/cjhs: . . . . Tue, Nov 5, 9:03AM PDT (-0700 GMT). . . [67 ] does
it rain on mars?

Mark Stokes: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [69 ] Bob
- how does the makeup of the Mars atmosphere affect planet luminosity,
as in sunlight hitting particles in the atmosphere?
Matt/CJHS: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [70 ] Being
a surfer and a motorcycle rider doesn't fall under the usual scientist
stereotype. What compels you to pursue these hobbies?
Shaun/CJHS: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [71 ] Could
there be any chance of gradually inproving the surface and atmosphere
of mars so it may be inhabitable by humans?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [72
] Laura, I helped design the orbit. We really wanted to be able to see
the whole planet. That means a polar orbit with a short period.
kristy/cjhs: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [73 ] What
are your personal opinions on the life on Mars theory?
Jaime/CJHS: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [74 ] Bob
Haberle: Are you interacting with the student pet project That is taking
place from Oct.18 to Dec.10 ?
Lee: . . . . Tue, Nov 5, 9:04AM PDT (-0700 GMT). . . [75 ] Thought I
would say hello, all the way from England.
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). .
. [76 ] Joey/CJHS: Your question came through twice. Only hit the "Chat"
button when you respond, not "return."
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [77
] Matt, I grew up in Southern California during the 60's. Surfing and
Motorcycling were part of the culture.
REBEKAH/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [78 ]

makes this mission different from the ones 20 yrs ago with the U.S. and
the former Soviet Union?
Tom\CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [80 ] Are
there any specific discoveries about Mars that you are hoping the Mars
Global Surveyer will make?
Bethany/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [81 ]
Could the soil on Mars somehow be fertile enough to grow simple plants?
brian/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [82 ] Are
the weather patterns on Mars similiar to that of earth?
Jeff/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [83 ] What
if one of Mars moons gets in the Mars Global Sureyor flight path
Jenna/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [84 ] If
the Global Surveyor discovered something really exciting about Mars how
would you hadle the results?
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). .
. [85 ] Hello Lee in England! Thanks for joining us :-)
cyp: . . . . Tue, Nov 5, 9:06AM PDT (-0700 GMT). . . [86 ] St. Cyprian's
School in Lufkin, Texas, is also ready
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:06AM PDT (-0700 GMT). . . [87
] Kristy, on the issue of life on Mars. I'm skeptical. I've always felt
that if life got started there, it would still be there. But, I'd like
to see more data.
Bethany/CJHS: . . . . Tue, Nov 5, 9:06AM PDT (-0700 GMT). . . [88 ]
Could the soil on Mars somehow be fertile enough to grow simple plants?

Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:07AM PDT (-0700 GMT). .
. [91 ] STEPHANIE/CJHS: TURN OFF THE "CAPS LOCK." YOU ARE YELLING! Thanks
:-)
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:07AM PDT (-0700 GMT). . . [92
] Bethany. The soil would need quite a bit of fertilizer to grow anything.
And it would need to be protected from the uv radiation.
David/CJHS: . . . . Tue, Nov 5, 9:08AM PDT (-0700 GMT). . . [93 ] What
is your side on the theroy of, life came from Mars on a meteor in single
celled life form,in a sense made a spark of life on earth and then evolved
into the current of life on Earth
jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:08AM PDT (-0700 GMT).
. . [94 ] About how much data do you collect an hour from the shuttle
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:08AM PDT (-0700 GMT). . . [95
] Stephanie. Take all the math and science you can get.
Lee: . . . . Tue, Nov 5, 9:08AM PDT (-0700 GMT). . . [96 ] Good moning
( over there ) Sandy, what do you do?
Joey/CJHS: . . . . Tue, Nov 5, 9:10AM PDT (-0700 GMT). . . [97 ] do
you believe water could still exist under the surface of mars?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:10AM PDT (-0700 GMT). . . [98
] David on life. I'm not really an expert in this area, but my understanding
is that anything is possible. Its just that it is so hard to determine
what went on 4.5 billion years ago.
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:10AM PDT (-0700 GMT). .
. [99 ] jeri/Serrano Intermediate: Sorry, we can't answer your question
on the shuttle today. Bob Haberle is a Mars scientist. Do you have any
Mars-related questions for him?
?????: . . . . Tue, Nov 5, 9:10AM PDT (-0700 GMT). . . [100 ] Jamie/CJHS
thinks you hate her! Please tell her your not! :-)
Matt & Lydia: . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT). . . [101 ]
Hi, we are doing a project in school that involves landing a ship and
staying on mars for an extended period of time. Our question is does NASA
have any type of portable habitats that could be used to stay on the planet?
jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT).
. . [102 ] About how much data do you collect an hour from the shuttle
cyp: . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT). . . [103 ] Does the
Global Surveyor have navigational systems on board?
Lee: . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT). . . [104 ] if water
did still exist under the surface what else would it contain?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT). . . [105
] Joey on water. Absolutely! I'm convinces there is water on Mars buried
beneath the surface. Its just a matter of how deep it is. At the poles
it could be very close to the surface. Indeed at the north pole it is
at the surface.
Shumate Middle School: . . . . Tue, Nov 5, 9:11AM PDT (-0700 GMT). .
. [106 ] How long do you think the current dust storm on Mars will last?
Do you think it will affect our mission plans? (Amanda Duncan)
Charlie/Gates Intermediate: . . . . Tue, Nov 5, 9:12AM PDT (-0700 GMT).
. . [107 ] I'm back!!
KrissclassCMS: . . . . Tue, Nov 5, 9:12AM PDT (-0700 GMT). . . [108
] Hi Bob we are joining the Chat now. We are five sixth grade students
from Columbine Middle School in Montrose Colorado.
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:13AM PDT (-0700 GMT). . . [109
] Matt and Lydia. I'm not sure NASA has built any portable habitats for
extended stays on Mars, but they have looked at various designs.
Lee: . . . . Tue, Nov 5, 9:13AM PDT (-0700 GMT). . . [110 ] Matt and
Lydia, would the astonauts not suffer from calcium defiency due to so
long in zero gravity and so be too itll to live on mars.
jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:13AM PDT (-0700 GMT).
. . [111 ] what is Mars mainly made of?
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:14AM PDT (-0700 GMT). .
. [112 ] Welcome sixth grade students from Columbine Middle School in
Montrose Colorado!
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:14AM PDT (-0700 GMT). . . [113
] One of the biggest problems we need to solve if we are going to send
humans to Mars is the prolonged weightlessness that they must endure.
Shaun/CJHS: . . . . Tue, Nov 5, 9:15AM PDT (-0700 GMT). . . [114 ] Bob:
Did you get Jamie's question and my question? Most of us allready have
answers! PLEASE!!!! :-)
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:15AM PDT (-0700 GMT). .
. [115 ] As I'm sure you can all see, there are TONS of questions for
Bob to answer. Slow down a bit please! He's beginning to get cramps in
his fingers from typing soooooo fast :-)
KrissclassCMS: . . . . Tue, Nov 5, 9:15AM PDT (-0700 GMT). . . [116
] Bob when did you realize that you wanted to be a scientist for NASA?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:15AM PDT (-0700 GMT). . . [117
] Jeri. Mars is made of rocks containing silicon, iron, and various minerals.
It also has an atmosphere of Carbon Dioxide.
Joey/CJHS: . . . . Tue, Nov 5, 9:15AM PDT (-0700 GMT). . . [118 ] based
on what you know,could life survive on mars,if not could we change it's
environment so it could?
Matt: . . . . Tue, Nov 5, 9:16AM PDT (-0700 GMT). . . [119 ] No, our
ship is making artificial gravivity by rotating. That means that they
will not have any type of deficiancy.
jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:16AM PDT (-0700 GMT).
. . [120 ] Are you still there ?
Lee: . . . . Tue, Nov 5, 9:16AM PDT (-0700 GMT). . . [121 ] Hello 6th
grade students!
David/CJHS: . . . . Tue, Nov 5, 9:16AM PDT (-0700 GMT). . . [122 ] Is
there a chance that a layer of permafrost could be blocking oter minerals
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:16AM PDT (-0700 GMT). . . [123
] Shaun/Jamie. I didn't get your question.
: . . . . Tue, Nov 5, 9:17AM PDT (-0700 GMT). . . [124 ] What is a Alpha
Proton X-ray Spectrometer (Apxs)
Lee: . . . . Tue, Nov 5, 9:17AM PDT (-0700 GMT). . . [125 ] What do
youunderstand about the evidence for Life on Mars, theory?
cyp: . . . . Tue, Nov 5, 9:17AM PDT (-0700 GMT). . . [126 ] Does the
Global Surveyor have navigational systems on board?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:17AM PDT (-0700 GMT). . . [127
] David. There is a good chance that permafrost exists on Mars. And it
could certainly be blocking other minerals.
Lee: . . . . Tue, Nov 5, 9:18AM PDT (-0700 GMT). . . [128 ] With living
on Mars, how much food would you need and whee would you store it?
KrissclassCMS: . . . . Tue, Nov 5, 9:18AM PDT (-0700 GMT). . . [129
] When the sojourner is on a hill and the sun goes down will it roll down
the hill or does it have a parking brake?
Bethany/CJHS: . . . . Tue, Nov 5, 9:18AM PDT (-0700 GMT). . . [130 ]
Do you know of any natural resources on Mars?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:18AM PDT (-0700 GMT). . . [131
] Cyp. Yes, MGS does have onboad navigational systems to help it get to
Mars. By the way it launches tommorrow. Let all keep our fingers crossed!!!!

jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:19AM PDT (-0700 GMT).
. . [135 ] Does Mars have different seasons ?
Laura/CJHS: . . . . Tue, Nov 5, 9:19AM PDT (-0700 GMT). . . [136 ] What
ideas did you contribute to the Mars Global Surveyor?
brian/CJHS: . . . . Tue, Nov 5, 9:19AM PDT (-0700 GMT). . . [137 ] Are
the weather patterns on Mars similiar to that of earth?
Jaime/CJHS: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [138 ] Bob
Haberle: Are you interacting with the student PET project, taking place
from Oct.18 to Dec.10 ?
Tom\CJHS: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [139 ] Are
there any dicoveries about Mars that you are hoping that the Mars global
Surveyer will make?

Jenna/CJHS: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [142 ] If
the Global Surveyor discoverd something really exciting out about Mars
how would you handle the results?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [143
] Krissclass. Sojouner doesn't have a parking brake in the sense you think
of. But it can stop its wheels from turning. Also, the camera on Pathfiner
will tell us if it is on a hill or not.
Joey/CJHS: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [144 ] based
on what you know,could life still exist on mars,if not could we change
it's environment so it could.
Lee: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [145 ] Difference
is that the USA is the leader in the race to Mars.
Mike/Gates intermediate: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT).
. . [146 ] sorry about that
STEPHANIE/CJHS: . . . . Tue, Nov 5, 9:21AM PDT (-0700 GMT). . . [147
] What advise do you have for someone someone that would be interested
in what you do?
Lee: . . . . Tue, Nov 5, 9:21AM PDT (-0700 GMT). . . [148 ] Joey, is
that not like playing God!
jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:21AM PDT (-0700 GMT).
. . [149 ] If mars does have seasons how long is each season ?
Jeff/CJHS: . . . . Tue, Nov 5, 9:21AM PDT (-0700 GMT). . . [150 ] What
if one of Mars moons gets in the Mars Global Surveyor flight path
KrissclassCMS: . . . . Tue, Nov 5, 9:22AM PDT (-0700 GMT). . . [151
] Does the Sojourner have steel wheels or rubber wheels? We wouldn't think
that it would be able to climb rocks if it had steel wheels.
Mark Stokes: . . . . Tue, Nov 5, 9:22AM PDT (-0700 GMT). . . [152 ]
Bob - how does the density of Mars' atmosphere affect the entry of a spacecraft
(speed, heat shield, etc.) as opposed to earths' atmosphere?
kristy/cjhs: . . . . Tue, Nov 5, 9:22AM PDT (-0700 GMT). . . [153 ]
What are your personal opinions on the life on Mars theory?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:22AM PDT (-0700 GMT). . . [154
] Megan. MGS differs from the Viking Mission of 20 years ago in that it
is intended to map the entire surface of Mars for one Mars year. Also,
MGS does not have any landers. It is an orbiter. We want to really be
able to characterize the global nature of Mars both its surface and atmosphere.
Matt: . . . . Tue, Nov 5, 9:22AM PDT (-0700 GMT). . . [155 ] is it possible
for humans to terra form Mars? If yes how would they start to go about
it?
KrissclassCMS: . . . . Tue, Nov 5, 9:23AM PDT (-0700 GMT). . . [156
] How long have you worked for NASA?
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:23AM PDT (-0700 GMT). .
. [157 ] Stephanie: I believe someone asked that same question earlier
and Bob said to take as many math and science courses as you can!
megan/CJHS: . . . . Tue, Nov 5, 9:24AM PDT (-0700 GMT). . . [158 ] What
instruments will be used to study the atmosphere?
chris/cjhs: . . . . Tue, Nov 5, 9:24AM PDT (-0700 GMT). . . [159 ] does
it rain on mars?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:24AM PDT (-0700 GMT). . . [160
] Jeff/CJHS. Mars has seasons quite like our own, but they last about
twice as long. Also Mars is in a very elliptical orbit compared to Earth
so its winters in the north are much warmer than its winter in the south.
So if you want to live there, I'd recommend going north!
Rebekah/CJHS: . . . . Tue, Nov 5, 9:24AM PDT (-0700 GMT). . . [161 ]
Was there any particular person who influenced you to choose your career?
Who are they and what influence did they have on you?
Matt/Cjhs: . . . . Tue, Nov 5, 9:24AM PDT (-0700 GMT). . . [162 ] Hey
Bob. Come back
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:25AM PDT (-0700 GMT). .
. [163 ] These are some of THE best questions we've ever had during our
WebChats. There are about 30 questions that still need to be answered.
In 15 mins. (9:45 PST) we'll stop taking questions so that Bob can answer
the ones you've already sent in.
Tom\CJHS: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [164 ] Are
you hoping that the Mars Global Surveyer will make any particular dicoveries
about Mars?
brian/CJHS: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [165 ] Are
the weather patterns on Mars similiar to that on earth?
cyp: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [166 ] Does the
Global Surveyor have navigational systems on board?
megan/CJHS: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [167 ] matt
don't be so mean.
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [168
] Megan/CJHS. There are a number of instruments on MGS that can study
the atmosphere. First there is a camera that can take pictures so we can
see clouds and dust storms. Then, there is a "Thermal Emission Spectrometer"
which can tell us what the temperature of the atmosphere is. And there
is a radio experiment that will do the same thing, but at much higher
resolution.
Bethany/CJHS: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [169 ]
Do you know of any natural resources on Mars?
Joey/CJHS: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [170 ] Do
you think there is any chance for life to still exist on mars today?
Hunters Woods: . . . . Tue, Nov 5, 9:26AM PDT (-0700 GMT). . . [171
] We have seen the JPL CD- Rom, Mars Navigator. It shows an experiment
where a signal is sent to the MGS & gathers data on the atmosphere. Are
you part of this experiment?
mike/gates: . . . . Tue, Nov 5, 9:27AM PDT (-0700 GMT). . . [172 ] I
keep getting thrown out
Jaime/CJHS: . . . . Tue, Nov 5, 9:27AM PDT (-0700 GMT). . . [173 ] Bob
Haberle: Please try to get my question this time, here it is: Are you
going to be interacting with the student PET project taking place from
Oct.18 through Dec.10 ?
jason/riverdale: . . . . Tue, Nov 5, 9:27AM PDT (-0700 GMT). . . [174

jeri/Serrano Intermediate : . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT).
. . [176 ] Are you still here?
dole,bob: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [177 ] Who
are you voting for?
Mr. N@Riverdale: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [178
] Hi Dr. Haberle, Our class wants to know how to say your last name. I
want to know how we might increase the density of atmoshere on Mars. Possible?
: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [179 ] How is the
MGS powered, and how is it going to stay aligned with Mars's orbit
Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). .
. [180 ] cyp: Use your Scroll Back messages box to find the answer to
your question re: nav systems onboard Surveyor. Bob answered that earlier
in the chat.
chris/CJHS: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [181 ] Does
it rain on Mars?
David/CJHS: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [182 ] Is
there a chance that there are undiscoverd minerals on Mars
Yoda: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [183 ] Anybody
out there?
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [184
] Tom/CJHS. I'm hoping that MGS will see a global dust storm develop.
These are specatular events. The winds get so strong (over 100 miles per
hour near the surface) that dust gets lifted almost everywhere. Eventually
the entire planet gets covered with dust up to 50 km high. I just can't
imagine what it would be like to be there when it occurs. If MGS sees

(about half as big as earth) so it doesn't have a very strong gravity
field to keep things around. But this is just a guess. (Yes, scientists

] Shaun/cjhs. In principle it would be possible to change the surface
and atmosphere of Mars if it has the basic ingredients to do so. You need
lots of CO2 and water to make a greenhouse, and you need lots of nitrogen
to make it like the earth. My feeling is that the required amounts are
not there. Even if they were it would take hundreds of thousands of years
to make it like Earth because of the energy needed. But its fun to think
about isn't it?

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:42AM PDT (-0700 GMT). . . [265
] Maddyp. Plants cannot grow on Mars without help. Lots of help. The soil
has toxic gases in it, and ultrviolet radiation gets all the way to the
surface and it would sterilize any plants you tried to grow. But if you
sheltered them, and f ertilized them, it migth be possible.

on Mars.
Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:55AM PDT (-0700 GMT). . . [331

Surface pressure is only about 7 mb compared to Earth's 1013 mb. The most
interesting thing about it is that it has huge dust storms. they cover
the entire planet.
