Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:01AM PDT (-0700 GMT). . . [56 ] Hello Everyone! Welcome to the second LIVE FROM MARS 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.

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 ] Was there any particular person who influenced yo to choose your career? Who are they and what influence did they have on you?

megan/CJHS: . . . . Tue, Nov 5, 9:05AM PDT (-0700 GMT). . . [79 ] What 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!!!!

Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:18AM PDT (-0700 GMT). . . [132 ] To: Anonymous: Please type your name in where it says "Your Handle" and then we'll try and answer your question! Thanks.: . . . . Tue, Nov 5, 9:17AM PDT (-0700 GMT). . . [124 ] What is a Alpha Proton X-ray Spectrometer (Apxs)

chris/cjhs: . . . . Tue, Nov 5, 9:19AM PDT (-0700 GMT). . . [133 ] does it rain on mars?

megan/CJHS: . . . . Tue, Nov 5, 9:19AM PDT (-0700 GMT). . . [134 ] What makes this mission different from the ones 20 yrs ago with the U.S.and the former Soviet Union?

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?

Shaun/CJHS: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [140 ] Could there be any chance og gradually improving the surface and atmosphere of Mars so it may be inhabitable by humans?

Matt: . . . . Tue, Nov 5, 9:20AM PDT (-0700 GMT). . . [141 ] How do scientist test for chemicals and elements on the Red Planet?

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 ] hi dr. bob

STEPHANIE/CJHS: . . . . Tue, Nov 5, 9:27AM PDT (-0700 GMT). . . [175 ]

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 one we will be able to watch it in great detail.

mike/gates: . . . . Tue, Nov 5, 9:28AM PDT (-0700 GMT). . . [185 ] What is a Alpha Proton X-ray Spectrometer (APXS)

Razor-riverdale: . . . . Tue, Nov 5, 9:29AM PDT (-0700 GMT). . . [186 ] Do you think the poler ice caps can be melted.

maddyb @ Riverdale: . . . . Tue, Nov 5, 9:29AM PDT (-0700 GMT). . . [187 ] Hello! I am here!

Mr. N@Riverdale: . . . . Tue, Nov 5, 9:29AM PDT (-0700 GMT). . . [188 ] 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, 9:30AM PDT (-0700 GMT). . . [189 ] Jaime: you asked if Bob would be participating in the PET project. The answer is no. That is a student-to-student debate. We may have some expert interactions with NASA folk, but it is mainly for students to work together to produce a set of instruments

Yoda: . . . . Tue, Nov 5, 9:30AM PDT (-0700 GMT). . . [190 ] Could the human race colonise mars ( after altering the atmosphere ) ?

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:31AM PDT (-0700 GMT). . . [197 ] Chris. It doesn't rain on Mars like it does here on Earth. Mars dust have clouds of water, but it is soooooo coooold there that they are little tiny ice crystals that ever so gently float through the atmosphere. Kind of like a misty fog.

Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:31AM PDT (-0700 GMT). . . [198 ] Yoda: Yes, we are all here. Do you have a question about Mars for Bob Haberle, the atmospheric scientist for Mars Global Surveyor?

Marc (California): . . . . Tue, Nov 5, 9:31AM PDT (-0700 GMT). . . [199 ] Sorry, the .... response about PEt project was me. I work with Sandy to produce the online parts of LFM

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:31AM PDT (-0700 GMT). . . [200 ] Jamie. I'm not even sure what the PET project is. But I'm willing to participate.

Question: Deimos and Phobos orbit around Mars right, and they go the same way right, how could they go the same way and one goes to the West and one goes to the East? Please respond. M.J.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:33AM PDT (-0700 GMT). . . [207 ] Yoda. NO! Keep Mars as it is. We should find other ways to solve our pollution problem.

valc/riverdale: . . . . Tue, Nov 5, 9:34AM PDT (-0700 GMT). . . [219 ] If some one planted plants on mars would people be able to breathe?

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:34AM PDT (-0700 GMT). . . [220 ] Regarding phobos and diemos. One appears to go in the opposite di direction from the other because the move at different speeds. One is very close in the other is far out (wow, far out!).

Marc (California): . . . . Tue, Nov 5, 9:36AM PDT (-0700 GMT). . . [234 ] MJ It is cheating to ask Bob Haberle to answer the question about the moons. That is this week's LFM Challenge Question. You should try to figure it out on your own, not by getting a real Mars expert to do "your homework for you"

maddyb @ Riverdale: . . . . Tue, Nov 5, 9:36AM PDT (-0700 GMT). . . [235 ] Oh. Dr. Haberle, do you think a plant could grow on Mars?

KrissclassCMS: . . . . Tue, Nov 5, 9:36AM PDT (-0700 GMT). . . [237 ] Does the Sojourner have steel wheels or rubbber wheels? We would think that it would be hard to climb rocks and hills with steel wheels.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:37AM PDT (-0700 GMT). . . [242 ] Chris. I'm not sure really why Mars doesn't have rings. I'll ask my colleague about that. My guess is because of its size. Its a small planet, (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 do guess!)

Yoda: . . . . Tue, Nov 5, 9:38AM PDT (-0700 GMT). . . [247 ] Ellie @ Riverdale, but would the oxygen react with anything else in thre atmosphere? Could help life on its way!

Mark Stokes: . . . . Tue, Nov 5, 9:39AM PDT (-0700 GMT). . . [248 ] Hi Megan/Pekin (there's another Megan participating).

cheltef : . . . . Tue, Nov 5, 9:39AM PDT (-0700 GMT). . . [249 ] If you were to put an oxygen bomb on Mars what would happen to the atmosphere?

Razor-riverdale: . . . . Tue, Nov 5, 9:39AM PDT (-0700 GMT). . . [250 ] Do you think if mars a long time ago when mars had water and land and a ice on the north or south part of it melted and made water then sucked down to the southern part of it then brong it to the southern part and made the poller ice cap when the oldest ice age happed.

maddyb @ Riverdale: . . . . Tue, Nov 5, 9:39AM PDT (-0700 GMT). . . [251 ] Oh. Dr. Haberle, do you think a plant could grow on Mars?

BRIAN/gate: . . . . Tue, Nov 5, 9:40AM PDT (-0700 GMT). . . [254 ] WHY DO THE PICTURES COME IN STRIPS?

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:40AM PDT (-0700 GMT). . . [255 ] 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?

maddyb @ Riverdale: . . . . Tue, Nov 5, 9:40AM PDT (-0700 GMT). . . [256 ] Oh. Dr. Haberle, do you think a plant could grow on Mars?

BRIAN/gat: . . . . Tue, Nov 5, 9:42AM PDT (-0700 GMT). . . [264 ] IF YOU put water on the surface of mars what would it do?

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.

Sandy/NASA Chat Host: . . . . Tue, Nov 5, 9:42AM PDT (-0700 GMT). . . [266 ] EVERYONE: If you could hold your questions for the next 15 mins. Bob & I will try and answer the backlog of excellent questions.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:43AM PDT (-0700 GMT). . . [272 ] Maddyb. The great red spot has been around for at least 300 years. So I'd guess it will be around for another 300.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:44AM PDT (-0700 GMT). . . [279 ] Krissclass. I'm not sure what Sojourners wheels are made of but it can't be rubber. Rubber would get eatin alive at Mars. So the poor little thing would get four flat tires before it even got out of the garage.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:46AM PDT (-0700 GMT). . . [287 ] AMYV. It will take suveyor 10 months to get to Mars. Then when it gets there it will take another 4 or 5 months to get into its final orbit. So by April of 1998, we will finally start getting the data we've been waiting for for 20 years.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:48AM PDT (-0700 GMT). . . [294 ] Matt & Lydia. It is purely a politcal question regarding how long it will take to get humans to Mars. Such a mission will be very expensive (many billions of $). So its a matter of the public being willing to fund such an effort. My guess is we won't see it happen till 2020 or beyond.

[165 ] Are the weather patterns on Mars similiar to that on earth?

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:50AM PDT (-0700 GMT). . . [301 ] cyp. If a moon was in MGS's orbit, we would need some traffic cops to keep it from hitting our spacecraft. But the chances of a moon or even a rock being in MGS's orbit are very very very slim. So I don't think we need to worry about it.

We would like to know about the atmosphere of Mars. Use the scroll back messages box to see the previous text. We've been chatting for an hour now and many questions have been answered about the atmosphere on Mars.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 9:55AM PDT (-0700 GMT). . . [331 ] The atmosphere of Mars is mostly carbon dioxide. And its very thin. 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.

Mark Stokes: . . . . Tue, Nov 5, 9:55AM PDT (-0700 GMT). . . [332 ] Bob, Sandy, Marc, Andrea and staff - thanks for a great chat and for devoting your time to this. Good questions and answers!

Marvin : . . . . Tue, Nov 5, 9:59AM PDT (-0700 GMT). . . [347 ] Is the atmosphere different on the north pole.

Bob/Haberle/NASA: . . . . Tue, Nov 5, 10:04AM PDT (-0700 GMT). . . [375 ] Mary-Julia. Without protect about 2 seconds. They would explode because of the low surface pressures. Not a pretty site.

Yoda: . . . . Tue, Nov 5, 10:04AM PDT (-0700 GMT). . . [376 ] Good Luck and thankyou!
