[ Sandy/NASAChatHost 09:57:32 ]
Hello Sandy! Good to talk to you again!
Good Morning Mrs. Dabbs and 1st graders! So glad you could make it again
this week :-) We'll start chatting in about 35 minutes!
[ MrsDabbs/1stGrade/WestView/Elementary 10:02:31 ]
Hello! Great, we will be back. Thanks!
[ DavidMittman/MPF 10:19:46 ]
RE: [Sandy/NASAChatHost] Good
Morning Mrs. Dabbs and 1st graders! So glad you could make it again this
week :-) We'll start chatting in about 35 minutes!
[ Sandy/NASAChatHost 10:25:51 ]
RE: [Tammie/Tikigaq] We were not able to RSVP
24 hours in advance due to an incorrect address in the initial message.
I didn't figure it out until this morning. I appologize for that. I'm
hoping there is still space available for us at this late notice because
my students have read the biography and written 5 questions. They are
Tammie: YES! There absolutely is room for you and your kids. We will begin
in about 10 minutes. Chat with you soon!
[ Sandy/NASAChatHost 10:31:55 ]
HELLO EVERYONE! Thanks for joining us for another Mars Team Online chat!
Our Mars expert today is David Mittman. David has worn three hats during
the Pathfinder mission: flight engineer, mission planner and flight controller.
Today he will bring us up to date on the Pathfinder and will tell us about
he and the PF team are moving on to new jobs.
[ Sandy/NASAChatHost 10:32:16 ]
[ Linda/Ames 10:32:43 ]
Tammy, Glad to see you found your way here!
[ Sandy/NASAChatHost 10:33:32 ]
We are back. Is Mr. Mittman here yet?
Welcome back to Mrs. Dabbs and 1st graders and also to Tammy and her 4th
[ DavidMittman/MPF 10:36:23 ]
RE: [MrsGinnyDexter] Dear David, My students are getting
ready to chat with you. They have been studying about Mars for a year.
They are 6/7 graders. They are in the process of doing the on-line Weather
Worlds Project. Learning about how to gather weather data on Mars. Last
year they went to Ames Research Center and met scientists that were involved
in the Mars Project. They have been following the new information/discoveries
on Mars. We are very pleased to get a chance to chat with you
Even though I'm not directly involved, I've been watching the Weather
Worlds mail just about daily. I'm glad to see it becoming such a "dynamic"
[ DavidMittman/MPF 10:37:43 ]
RE: [MrsDabbs/1stGrade/WestView/Elementary] Welcome Mr. Mittman!
My students have a question for you: How long did it take for the Pathfinder
to get to Mars?
Hello MrsDabbs/1stGrade/WestView/Elementary! The Mars Pathfinder spacecraft
launched from Florida on December 4th, 1996 and landed on Mars on July
4th 1997. That's seven months of interplanetary travel!
[ Sandy/NASAChatHost10:37:44 ]
RE: [Amanda6/7class] Hi Mrs Dexter's 6/7 class is here to
ask some guestions!
Ask away Amanda :-)
[ DavidMittman/MPF 10:39:34 ]
RE: [Amanda6/7class] Do you enjoy being a Flight Engineer
Amanda6/7class: Being a Mars Pathfinder flight engineer is without a doubt
the most exciting thing that I've ever done here at the Jet Propulsion
Laboratory. When I saw my name on the list of "Flight Engineers" way back
when, I kept asking mission manager Richard Cook if he really meant to
include me! I couldn't believe it!
[ DavidMittman/MPF 10:41:05 ]
RE: [Megan/DenverCO] As a flight controller on Pathfinder,
how many times/week are you talking to the Deep Space Network now? And
how often do they/you send a message to PF?
Megan: I'm no longer on "active duty" when it comes to being a Flight
Controller. Since we're only attempting to communicate with Pathfinder
about once a month, two other flight controllers get most of the flight
control shifts. :-( At the peak of my duties as Flight Controller, I'd
be working about 4 out of 10 days.
[ DavidMittman/MPF 10:41:50 ]
RE: [Megan/DenverCO] As a flight controller on Pathfinder,
how many times/week are you talking to the Deep Space Network now? And
how often do they/you send a message to PF?
Megan: I should also note that even though four out of ten days may not
seem like a lot, I also had my "regular" job as mission planner to do!
[ Sabrina6/7class 10:42:56 ]
Hi my name is Sabrina. I am at Hydesville school.Mrs.Dewxter whants to
know.What is you'r job know. The kids think that the pathfinder is not
giving any new info.
[ DavidMittman/MPF 10:52:49 ]
Sabrina: Thanks for asking about my job! I'm still working a couple of
hours a week on the Mars Pathfinder project while we write our "end of
mission" reports. (Just like you guys write book reports!) I spend most
of my time on a project known as the Space Infrared Telescope Facility
(SIRTF) which will launch in December 2001 and will take pictures of the
stars and galaxies for 2.5 years.
[ Megan/DenverCO 10:43:22 ]
How about your duties as Mission Planner--are they over also? Or are you
still the one sending the command to PF once a month? And you do decided
what to tell PF to do, for example PATHFINDER, PLEASE CALL HOME!!!
[ DavidMittman/MPF 10:54:28 ]
Megan: I'm still technically a Mars Pathfinder mission planner and flight
controller because there is still a Mars Pathfinder project. However,
my workload is very small since we aren't currently able to communicate
with the spacecraft. I may still get to send commands to the spacecraft
as a Flight Controller...it depends on when the Flight Controller's work
shift is during the day.
[ DavidMittman/MPF 10:43:30 ]
RE: [Amanda6/7class] when you were at the occidental college
did you ever think that you would work with Sojourner?
Answer: When I was in my last year at Occidental, I knew that I would
be going to work at the Jet Propulsion Laboratory, and I knew that JPL
did lots of interesting space exploration (my brother had also worked
at JPL many years ago). I had no idea that I'd be involved in something
as exciting or as important as the Mars Pathfinder project and Sojourner
[ AMY 10:44:32 ]
HOW LONG WERE YOU TRANING FOR THIS JOB?
[ DavidMittman/MPF 10:56:22 ]
Amy: My training for being a Flight Engineer started as soon as I started
working on Mars Pathfinder. The Flight Engineers use all their knowledge
of how the spacecraft works to do their jobs. My training to be a Flight
Controller took about three months, and started in early 1996.
[ Amanda6/7class 10:44:41 ]
did you wont to be a scientist when you were a kid?
[ Sandy/NASAChatHost 10:45:24 ]
RE: [unknown] Thank you for letting us chat
with you today. The kids say hello and we are very excited to talk with
David today. Our first question is: What is a Pathfinder and how do you
guide the Pathfinder? That question was written by Maggie Lane.
UNKNOWN: Please fill in your name so that David knows who to send his
response back to. Thanks :-)
[ DavidMittman/MPF 10:45:55 ]
RE: [MrsDabbs/1stGrade/WestView/Elementary] Mr. Mittman:
We have heard that the launcher is not responding. Is it fixed yet? If
not do you think it can be fixed? What are the chances of the pathfinder
returning to Earth?
MrsDabbs/1stGrade/WestView/Elementary: We're having trouble communicating
with the "lander" or Sagan Memorial Station that now sits on the surface
of Mars. We believe that it got too cold and that part of its radio no
longer works properly. We're going to continue to try to talk to it over
the coming months, but it is not very likely that we'll be successful.
The lander and rover Sojourner will remain on Mars until one of you young
people becomes an astronaut and goes up there and brings it back! It can't
come back on its own.
[ Sandy/NASAChatHost 10:46:52 ]
RE: [Kathy] Hi can I Join this chat? My network
was down and I was unable to register earlier.
Kathy: Just jump in and start asking questions! There is no advance registration
required for today's chat.
[ DavidMittman/MPF 10:47:01 ]
RE: [AMY] HOW LONG HAVE YOU BEEN A FLIGHT ENGNEER ON THE
MARS PATHFINDER PROJECT?
Amy: I've been working on Mars Pathfinder for about four years or so,
and was named as a Flight Engineer about two years ago.
[ MrsDabbs/1stGrade/WestView/Elementary10:47:08 ]
Mr. Mittman: Could people travel to Mars in the same time (7mons.) or
would it take longer?
[ DavidMittman/MPF 10:58:21 ]
MrsDabbs/1stGrade/WestView/Elementary: I imagine that people will eventually
be able to travel to Mars in about seven months. The difficulty is figuring
out how to survive for those seven months, plus the time it takes to return
[ Tammie/Tikigaq 10:47:15 ]
Oooops! That question that was previously asked was from me. I failed
to put my name on it. Let me repeat the question for my student Maggie.
She would like to know: What is a Pathfinder and how do you guide the
Pathfinder? Oh, by the way....this is a 4th grade class in Point Hope
Alaska. We are located above the Arctic Circle so during the winter we
can do a lot of star gazing with all the darkness we have.
[ EmilyStoller 10:47:18 ]
did you ever want to be something else than a space engineer?
[ DavidMittman/MPF 10:59:37 ]
Emily Stoller: My father is a physician and for the longest time I wanted
to be a doctor just like him. When I became interested in computers I
quickly changed my mind. I could still be a doctor, though, if I wanted
to...you should see my handwriting!
[ DavidMittman/MPF 10:48:28 ]
RE: [EmilyStoller] hello, my name is Emily. I would like
to know if you enjoy working with N.A.S.A.
Hello, Emily! Working with NASA means working for the best space exploration
and technology company in the world! Working at JPL means being associated
with *the* leading organization involved in exploring our solar system
with robotic spacecraft. It's a very good association!
[ WilliamRoberson 10:48:45 ]
Hello,what was the best pitcer pathfinder ever gave?
[ DavidMittman/MPF 11:01:44 ]
William Roberson: That's a fantastic question! Before landing I talked
about exciting pictures with my fellow Flight Engineers. We couldn't decide
if a picture of the Rover taken from the Lander would be more exciting
than a picture of the Lander from the Rover. It turns out that both were
very exciting! Seeing the Rover out on its own, and seeing the "mother
ship" the Lander from the rover are both exciting pictures. The color
image of the Rover still on its petal with "Twin Peaks" in the background
was also very exciting!
[ MrsDabbs/1stGrade/WestView/Elementary10:48:45 ]
Mr. Mittman: Do you believe in a 10th planet?
[ DavidMittman/MPF 11:02:27 ]
MrsDabbs/1stGrade/WestView/Elementary: I certainly am not about to say
that there is no 10th planet! I don't have enough information at this
point to really know.
[ Amanda6/7class 10:49:11 ]
Yesterday me and my friend Keeshia read your biography and we enjoyed
[ DavidMittman/MPF 11:02:55 ]
Amanda6/7class: Thanks for enjoying my biography! I've really enjoyed
[ Sandy/NASAChatHost 10:50:19 ]
RE: [Tammie/Tikigaq] Oooops! That question
that was previously asked was from me. I failed to put my name on it.
Let me repeat the question for my student Maggie. She would like to know:
What is a Pathfinder and how do you guide the Pathfinder? Oh, by the way....this
is a 4th grade class in Point Hope Alaska. We are located above the Arctic
Circle so during the winter we can do a lot of star gazing with all the
darkness we have.
Tammie: No problem! I can honestly say that you and your kids are the
very first people that we've had join us from ABOVE THE ARCTIC CIRCLE.
[ DavidMittman/MPF 10:50:26 ]
RE: [unknown] Thank you for letting us chat with you today.
The kids say hello and we are very excited to talk with David today. Our
first question is: What is a Pathfinder and how do you guide the Pathfinder?
That question was written by Maggie Lane.
Maggie: Pathfinder is acually two spacecraft in one. A lander which sits
still on the surface of Mars, and a rover which drives around the surface
and explores the area surrounding the lander. The Mars Pathfinder project
is the organization which designed, built, and operates the two spacecraft.
We tell the two spacecraft what to do by sending them "commands" by radio.
These commands cover a full day's activity and take about 16 minutes to
travel from Earth to Mars.
[ Amanda6/7class10:51:08 ]
Why did you decide to be a scientist?
[ DavidMittman/MPF 11:04:54 ]
Amanda6/7class: Actually, I'm not a 'scientist'. I've had some formal
training in science, but on Mars Pathfinder the scientists are "geologists",
etc. I'm technically considered an engineer. My earliest scientific/engineering
interests were as an elementary student.
[ MrsDabbs/1stGrade/WestView/Elementary 10:51:42 ]
Mr. Mittman: How big is the Pathfinder (length and weight)?
[ DavidMittman/MPF11:05:48 ]
MrsDabbs/1stGrade/WestView/Elementary: The lander weighs about 800 pounds
and is about seven feet across when fully open. The rover stands about
one foot high and two feet long and weighs about 25 pounds.
[ Sabrina6/7class 10:52:35 ]
Was it really fun when you got the first signal from the pathfinder.
[ DavidMittman/MPF 11:07:13 ]
Sabrina6/7class: Did you see the video footage of Jennifer Harris jumping
up and down when we received the signal which indicated that Pathfinder
had successfully landed on Mars? That's how we all felt. We had thought
that we wouldn't be able to get that signal and that we'd have to wait
three hours before learning of the lander's fate. We were lucky to have
gotten confirmation of landing as early as we did.
[ Amanda6/7class 10:53:06 ]
Hey David Whats the best part about working at JPL?
[ DavidMittman/MPF 11:08:13 ]
Amanda6/7class - 67: The best part of working at JPL is the teamwork.
Mars Pathfinder required a delicate ballet of parts and people, and we
really pulled it off!
[ MrsGinnyDexter 10:53:40 ]
did you like when you were training for your job
[ DavidMittman/MPF11:09:26 ]
MrsGinnyDexter: While being trained for being a Flight Controller and
Flight Engineer, I kept asking "Are you really going to allow me to do
this?" (This is the "grown-up" version of "pinching myself.)
[ Kathy 10:54:09 ]
The kids in Mrs. Mead's 3rd grade class at Westhampton Beach Elementary
School have been watching the Sojourner since the summer they are all
fascinated and are now comparing Earth to Mars. Do you expect to see future
research on Mars? Kathy Haack
[ DavidMittman/MPF11:10:46 ]
Kathy: Comparing Earth to Mars geology is a fantastic set of lesson plans!
NASA will be sending a mission to Mars about every 26 months, so you'll
be getting much more material for your lesson plans.
[ Tammie/Tikigaq 10:54:13 ]
Mr. Mittman, First of all, What is the Pathfinder? What does it feel like
to guide the Mars Pathfinder Spacecraft to Mars? from Vanessa in Point
[ Sandy/NASAChatHost 10:54:27 ]
RE: [EmilyStoller] Hey people is this cool
or what? we are talking to one of N.A.S.A's smartest reserchers!!!!!!!!!!!!!!!!!!
Emily: I agree with you 100 percent. I've done about 100 chats this past
year and each and every time I still get excited when I read questions
from kids and teachers and then see Mars experts' responses! Totally awesome
I say :-)
[ WilliamRoberson 10:54:29 ]
Hello agian,what didyou do with the pathfinder?
[ DavidMittman/MPF11:12:39 ]
William Roberson: Hello William! I wrote the software which was used to
help plan the lander's and rover's activities on the surface of Mars.
I also got to actually send commands to the spacecraft during its cruise
to Mars and during its surface mission (this is like being a DJ who gets
to play the hits on a radio station). I was also involved in the day-to-day
operation of the spacecraft.
[ shannoncooper10:55:56 ]
did you ever think this job was not right for you and if you did what
would you like to do instead
[ DavidMittman/MPF 11:14:21 ]
shannoncooper: Shannon, the hardest part of the job was the schedule.
I have a wife and two small children, and the job required a lot of time
away from home. Luckily, my wife is a school teacher, and when I was busiest,
she was on summer vacation. I'm probably not going to have an "operations"
role on a spacecraft anytime soon. I'll wait until my kids are a bit older.
[ Sandy/NASAChatHost 10:55:59 ]
RE: [Amanda6/7class] Talk to me!!!!!!!!
Amanda: As you can see, there are LOTS of people in this chat today! David
is trying very hard and typing very fast, in order to answer EVERYONE'S
questions, including yours!
[ MrsDabbs/1stGrade/WestView/Elementary 10:56:46 ]
Mr. Mittman: How long did your team work on the mission before it was
[ DavidMittman/MPF 11:15:32 ]
MrsDabbs/1stGrade/WestView/Elementary: From the time we got our formal
start until launch was about three-and-a-half years. In that time we had
to design, build, and test the entire spacecraft system (lander and rover),
and the entire ground system for making commands and getting data from
[ MrsDabbs/1stGrade/WestView/Elementary 10:57:40 ]
Mr. Mittman: How many people work on the team with you?
[ DavidMittman/MPF 11:17:02 ]
MrsDabbs/1stGrade/WestView/Elementary: There are about 12 Flight Engineers
about four of whom specialize in Mission Planning. The Flight Control
team had six members at its peak, three of whom were also Flight Engineers.
[ Amanda6/7class 10:58:40 ]
Is Sojourner still sending back new data?
[ DavidMittman/MPF 11:17:55 ]
Amanda6/7class: Sojourner radios all its data to the lander. Since we
can't communicate with the Lander, we don't know what the rover is doing.
Scientists here on the ground are still very busy analyzing the data we
[ GregatCKMS 10:59:50 ]
What programming languages, other than FORTRAN, do you need to know for
[ DavidMittman/MPF11:19:12 ]
GregatCKMS: English! That's the most important language you can know when
you are working as part of a team. Talk about what you're doing and listen
to what everyone else is doing. (Okay, the other answer to your question
is: C, C++, FORTRAN, and LISP.)
[ Kathy 11:00:01 ]
Can you explain to me how the messages go back and forth so quickly between
Earth and Mars? Jen from Westhampton Beach Elem. School - 3rd grade
[ DavidMittman/MPF11:20:35 ]
Kathy/Jen: The radio signals that we use to communicate with the lander
(all radio signals, actually) travel at the speed of light. Given the
distance between Earth and Mars, it now takes about 16 minutes for radio
signals (and light) to travel between the two planets. You'd have to double
that time if you're looking for a "return signal".
[ DavidatCKMS 11:00:31 ]
What got you interested in computer science?
[ DavidMittman/MPF11:20:35 ]
DavidatCKMS: I probably first got interested in computers because of my
older brother's incessant talk about them. Before that I spent all my
extra time with photography. In high school, I got a chance to use my
first personal computer, the Apple IIe.
[ Amanda6/7class 11:00:38 ]
Have you ever wished that you had a different job?
[ DavidMittman/MPF 11:22:35 ]
Amanda6/7class: Sure, I sort of wish I was Bill Gates... Actually, I have
a very strong interest in starting a computer software firm, but space
exploration is much more of a sure thing.
[ AMY11:00:42 ]
How long did it take you to get where you are today?
[ DavidMittman/MPF 11:23:13 ]
AMY - 92: I've worked at JPL for 11 years now! That's one year longer
than I've been married!
[ EmilyStoller11:00:52 ]
sorry, I forgot to say what school I'M FROM. I'M FROM Hydesville School.
are there many people working on the problem of sojourner on Mars?
[ DavidMittman/MPF11:24:33 ]
EmilyStoller: The flight team has shrunk over the past several weeks.
We've still got about a dozen people who are actively involved on the
project writing "end of mission" documentation. All the commands we're
sending to the spacecraft have already been developed...we're just waiting
to see of we get any kind of reaction from the spacecraft.
[ Amanda6/7class 11:02:33 ]
How many years were you in college?
[ DavidMittman/MPF11:25:12 ]
Amanda6/7class - 96: I've spent about four years in College, and came
to JPL right afterwards.
[ ScottatCKMS 11:02:45 ]
How often do you need to tell a scientist or team of scientists that they
can't do what they want to because the Pathfinder is not able to perform
[ DavidMittman/MPF 11:26:12 ]
ScottatCKMS: We had a couple of problems where the scientists wanted to
do something that the engineers didn't want to do. It wasn't a big problem.
Most of the "education" took place before landing while we worked out
our plans for the surface mission.
[ Kathy11:03:23 ]
Will you be building more Sojourners in the future? Katarina - Westhampton
Beach Elem. School, Mrs Mead's 3rd grade class
[ DavidMittman/MPF11:27:11 ]
Kathy: Yes, we'll be building more mars rovers. They'll have different
names and be going to different places on Mars, but they'll be just as
exciting. The next mars rover is scheduled for 2001 and it will travel
over greater distances.
[ Sabrina6/7class - 101 - 11:03:31 ]
What about the pathfinder do you like the most. I like the pictures.
[ DavidMittman/MPF 11:28:00 ]
Sabrina6/7class: For most people, the pictures and weather measurements
are the most exciting part. I enjoy imagining what it would have been
like to see this huge bouncy ball coming toward me on the surface of Mars!
[ WilliamRoberson - 102 - 11:03:50 ]
Hey, did you everdo something wrong in your job?
[ DavidMittman/MPF 11:28:50 ]
WilliamRoberson: Yup, I had one commanding error while on Flight Control
duty. I send a command a bit too early, but it didn't cause any difficulties.
[ Sethparker - 103 - 11:04:30 ]
How do you change inches into millibars on the barometor?
[ DavidMittman/MPF 11:29:15 ]
Sethparker - 103: I don't have an inch/millibar conversion handy. Sorry.
[ EmilyStoller 11:05:01 ]
Sandy, is there any proof of MARS PATHFINDER alive on mars?
[ DavidMittman/MPF 11:30:27 ]
EmilyStoller - 106: I think you're asking if we have any proof that Mars
Pathfinder is still working on Mars now. The answer is no, we have no
information which tells us its condition either way. That's what is so
frustrating about trying to fix the problem...no information on what's
[ Amanda6/7class 11:05:03 ]
Why did you decide to be a Flight Engineer?
[ DavidMittman/MPF 11:31:23 ]
Amanda6/7class - 107: The flight engineers were picked from amongst those
people who knew the most about how the spacecraft works. I designed a
bunch of software which behaved like the spacecraft, so I knew alot about
how it actually worked. That's why I was picked as a flight engineer.
[ Kathy 11:05:04 ]
Did you find out what most of the rocks were made of? Brooke from Westhampton
Beach Elem. School, Mrs. Mead's 3rd class
[ DavidMittman/MPF11:34:17 ]
Kathy - 108: The scientists believe that there are two classes or groups
of rocks in our landing area: one set is high in sulphur and the other
is high in silica. They'll continue to analyze their data in the coming
months as they have a chance to calibrate the data to make sure they understand
just what the data is telling them. There also may be evidence for what
is called a "conglomerate" rock which indicate some kind of cementing
via a water process.
[ Sandy/NASAChatHost 11:05:20 ]
RE: [Sethparker]How do you change inches into
millibars on the barometor?
Seth: Hey, that sounds like a homework question to me :-)
[ Sethparker 11:06:31 ]
Not to me. No.
[ calebb/dms 11:06:02 ]
how come there are two polar caps on mars when they say there is no moister
[ DavidMittman/MPF11:35:17 ]
calebb/dms: The polar caps are made from frozen carbon dioxide (dry ice),
not water. Instead of melting the frozen carbon dioxide goes directly
from its frozen state to a gas.
[ SebastianatCKMS 11:06:31 ]
Do you still use FORTRAN to program the Pathfinder's computer?
[ DavidMittman/MPF 11:36:06 ]
SebastianatCKMS: The Pathfinder computer was programmed in C, C++. We
use a special language when we build command sequences for the lander
[ Kathy - 114 - 11:07:12 ]
Do you think Sojourner shut down because of something on the surface of
Mars besides extreme cold? Joe from Westhampton Beach Elem. School, Mrs.
Mead's 3rd grade class
[ DavidMittman/MPF 11:36:41 ]
Kathy - 114: I think that when we finally lost the battery on the lander,
things got very cold and something in the lander's radio broke.
[ Tammie/Tikigaq 11:08:19 ]
This is another question from Point Hope. However, before we ask this
question you should know that our whole classroom cheered when we found
out we were the first school from the Arctic to chat with you. How exciting!!!
Point Hope is an Inupiaq Eskimo Village with about 750 people living here.
My students can't wait for us to learn more about the moon and all the
other planets out their. We just purchase a new telescope last year and
are looking forward to taking a peek. Now back to our next question. This
one is from Adam Tooyak: What is it like to be a Scientist for Nasa? Wow,
what a job!!!
[ DavidMittman/MPF 11:38:25 ]
Tammie/Tikigaq: I've been interested in astonomy for a while, but haven't
been able to find the time to actually go out and stargaze. Now that I'm
working on SIRTF, I've been able to learn a lot about the stars. I've
even started reading astronomy magazines. Working for NASA is one of those
"wow, what a job" jobs. Where else can you get paid for learning a bunch
of new and interesting stuff!
[ TylerCKMS 11:08:24 ]
Do the pictures from Mars come back in black and white or color? Are you
able to change them from BW to color?
[ DavidMittman/MPF 11:39:58 ]
TylerCKMS: Good question! The pictures come back in what is called "grey
scale". Each dot or pixel in the picture is given a gray scale measure
from 0 to 255 representing its darkness. When we want color pictures,
we take three of these pictures, each through a different color filter,
and combine them on the ground into one color picture.
[ EmilyStoller 11:08:32 ]
do you have fun at N.A.S.A.?
[ phillipdms - 121 - 11:08:53 ]
Are there really mountains on mars?
[ DavidMittman/MPF 11:40:53 ]
phillipdms: There really are mountains on Mars! Just take a look at the
horizon in some of our Mars Pathfinder photos! There are also huge canyons,
and the largest volcano in the solar system is on Mars.
[ Sandy/NASAChatHost 11:09:04 ]
RE: [EmilyStoller] Sandy, is there any proof
of MARS PATHFINDER alive on mars?
Emily: I'm going to let David answer that one. All is I know is that the
team has not heard from Pathfinder. I don't believe they're ready to say
it's dead because they're still sending messages once/month.
[ Morgan 11:09:30 ]
Will people ever beable to live on Mars.
[ DavidMittman/MPF11:41:51 ]
Morgan: I think that eventually, people will be able to live on Mars while
conducting scientific research. I don't think that ordinary people (non-scientists)
will want to live on Mars any time soon.
[ JennaRenfroDMS:10:34 ]
How often do people go up into space?
[ DavidMittman/MPF11:42:29 ]
JennaRenfroDMS: Jenna (I like that name!): People get into space now only
on the Space Shuttle or on the Russian Space Station Mir.
[ WilliamRoberson:10:57 ]
You do not need to answer my last question.
[ Sabrina6/7class 11:11:03 ]
How many questions have you got about the pathfinder.
[ DavidMittman/MPF 11:43:05 ]
Sabrina6/7class - 128: I've easily answered about 1000 questions about
Pathfinder from lots of different people.
[ Russ 11:11:07 ]
Why are the clouds frozen on Mars
[ DavidMittman/MPF 11:44:01 ]
Russ - 129: Clouds of carbon dioxide gas and possible water vapor form
when the temperature and pressure is just right. We've been able to see
early morning clouds of carbon dioxide in our pictures from the surface

Have you ever messed up in your job?
[ Kathy 11:13:50 ]
First of all we would like to thank you for getting on line with us today.
What a thrill, we are really excited. Do you usually get to work with
kids? Do you like working with kids? from all of us at Westhampton Beach
[ DavidMittman/MPF 11:46:30 ]
Kathy: I try to talk to kids groups whenever I get the chance. I love
working with kids and getting them interested in science.
[ DREWGDMS11:14:03 ]
Will there be another pathfinder? and if so will it be better than the
[ DavidMittman/MPF11:47:18 ]
DREWGDMS: There will be more Mars spacecraft, each with their own strengths.
Hopefully, they'll all be successful in doing what they're designed to

RE: [EmilyStoller] Did you eve... got to go
Goodbye Emily. Good questions, thanks!
[ Tammie/Tikigaq 11:17:19 ]
Yes, you answered our question of what the Pathfinder and Rover are. Vanessa
would still like to know what it feels like to have helped with such a
mission as guiding the Pathfinder to Mars. She would also like to know
if any life exists on Mars? Thank you!
[ DavidMittman/MPF 11:48:23 ]
Tammie/Tikigaq: I feel proud to have been part of the Mars Pathfinder
project. I don't believe that life as we know it exists on Mars.
[ Jessica11:18:57 ]
do you think there is a possibilty of life on mars.
[ Tammie/Tikigaq 11:20:58 ]
Our last but not least question from Point Hope is from Irene Gallahorn....How
do you know about your job and your journal said you never studied? What's
[ DavidMittman/MPF 11:49:50 ]
Tammie/Tikigaq: There are alot of things that you'll do in life for which
there are no classes...even at the college level. If you're expected to
do something no one else has done, where do you go to take a class!?!?
[ russ 11:23:00 ]
how come Mars has weather like Earth?
[ DavidMittman/MPF11:50:44 ]
russ: Mars' weather is only slightly like Earth's. Mars is somewhat similar
because Mars has an atmosphere (although it is very thin). Mars also undergoes
heating from the Sun. Those are the basics of weather.
[ Tammie/Tikigaq 11:23:52 ]
A big thank you from the 4th graders in Point Hope!! Keep up the good
work so we can learn more about the Solar System!! Hope we can chat again
[ Sandy/NASAChatHost 11:26:35 ]
RE: [Tammie/Tikigaq] A big thank you from the
4th graders in Point Hope!! Keep up the good work so we can learn more
about the Solar System!! Hope we can chat again soon!!!Thanks Again
Tammie: We hope you and your kids can chat with us again also! Keep watching
the MTO chat page for future chats. I hope to have another Web chat next
week and will advertize it by the end of the week. Stay warm :-)
[ MORGAN 11:27:19 ]
How many jobs do you have?
[ DavidMittman/MPF 11:51:45 ]
MORGAN: Right now, I'm working on Mars Pathfinder and on the Space Infrared
Telescope Facility. Two jobs. I used to do a couple of different things
on Mars Pathfinder (Flight Engineer, Mission Planner, Flight Controller...)
[ Kathy 11:30:26 ]
I am in Mrs. Mead's 3rd grade class at Westhampton Beach Elem. School,
New York. What was your favorite subject when you were in 3rd grade? My
favorite subject is working on our Sojourner project. - Michael
[ DavidMittman/MPF 11:52:24 ]
Kathy/Michael: I always like the math book in elementary schools. You
know, where you learn about sets and set membership and stuff.
