Animated video of Exploration Rover Mission to Mars
Stephanie speaking on screen
Stephanie: Good afternoon, and welcome to the Women
Working on Mars Web cast. Im Stephanie [Leevens] and for the next
hour Im going to be your host as we talk to women scientists and
engineers and find out what they do to make this mission successful.
This Web cast is being offered through the joint efforts
of the Mars Exploration Program, NASA Quest and the National Robotics
Education program. First Id like to extend a special welcome to
some of our participants. NASA headquarters, the regional NASA centers,
[Michelle Viotti] the Manager of the Mars Public Engagement Program, Marc
Leon of the Learning Technologies and Robotics Project, and the Department
of Housing and Urban Development, in particular Delores [Pruden], [Shelly
McCunes], [Vina Leeman] and [Steve McLaine], also Raytheon [ITSS].
Before we get started, lets talk a little bit
about what the Mars Exploration Rover Mission is. In 2004, twin rovers
are going to land on Mars where they will be studying the geology and
the climate of the planet. And if you were tuned in earlier, you saw some
of that animation.
Right now were going to show you a little bit
more of some animation like that, that sort of simulates what this mission
might look like.
Animated video of exploration of Mars
Stephanie: Now it takes lots of people to make a mission
like this successful. And luckily today were going to meet many
of the people that work to do that. We want to remind you that we can
answer your questions live here during this Web cast if you just send
them in, in the chat room. So we look forward to hearing from you.
Stephanie, Deborah, and Diana shown on screen
Now joining me today are two scientists that were
going to talk to first. We have Deborah [Bass] and Diana Blaney. Thank
you so much for being here. And theyre going to talk just a little
bit about the science of the mission. So Deborah, would you start us off?
Tell us about the science.
Deborah: Hi, Im Deborah Bass and I want to tell
you about the Mars Exploration Rovers. We call these rovers M-E-R, or
MER, and youll here us referring to M-E-R or MER sometimes during
this Web cast.
What were going to do is send two identical
rovers to two different locations on Mars to discover some things about
whether water existed in the past. We can do that, as you saw on the video,
by looking at things like layers.
Deborah speaking on screen
Layers that must have been deposited in water or layers
that also must be chemically bound up to water.
So there are things, there are chemical signatures
that we can also identify as evidence of past water. What I do on MER
is to -- Im a science operations system engineer -- and what Im
trying to do is facilitate the science. I talk to the engineers who are
developing the software as well as the hardware, and I work with them
as well as working with the science team. And try to make sure that the
most science possible we can get out of this mission.
Stephanie, Deborah, Diana on screen
Stephanie: Thats great. Thank you so much, Deborah.
How about you, Diana? I know youre also a scientist, but you do
something a little bit different.
Diana speaking on screen
Diana: Yeah, rather-, I worry about one instrument
on the rover. Its called Mini-Test. And what it does is it tells
you what the rocks are made out of. And I basically go and make sure that
everything from Mini-Test works. I worry about the thermal environment,
the calibration of the instrument.
At the end of all this, Im going to be one of
the people who get to operate the instrument. And having been there through
the beginning, through the end, through the calibration, Ill have
a really good understanding of whats going on.
The other thing I do is I answer questions about whats
going on with Mini-Test for the engineering team. Its a big project
and a lot of things interact and are very complex. And so Im kind
of a point of contact for some of the engineers. If theyve got a
question about how does Mini-Test work, what its going to do, things
like that.
And in my free time I do real grounded, real science.
Looking at Mars through telescopes.
Stephanie, Deborah, Diana on screen
Stephanie: Thats so great. Thats really
interesting. Now I think we have some questions from our online chat room
and Cathy [Bowmans] from the Robotics Education Project is fielding those
for us. Thank you, Cathy. Youll hear her voice. Why dont you
give us one. Are you guys ready? Okay.
Cathy: Sure. Im glad everyones participating
today. We have a question here from Cindy in [Hayworth] who says, what
would you do if youre sending a robot to an unfamiliar place? What
kind of tests would you perform?
Diana speaking on screen
Diana: Well you try to learn as much about the place
before you send it and then make some predictions about what youre
going to find. You test for what you expect and then you put error bars
on it. So for instance, we know a lot about how geology works, and like
so if were sending it to a place where theres volcanoes, well
go to volcanoes on Earth and understand whats going on.
Wed send them to lake beds. We look at those
kinds of analogs to figure out where the environment we need to test.
But since its unknown, were not going to really know everything.
Stephani, Deborah, Diana on screen
Cathy?: Okay, weve got another question coming
from Rachel whos in Mrs. Petersons fourth grade. She asks
what, so how do you get the idea of making two Mars land rovers, and I
would say more specifically, whats the benefit of having two rovers?
Deborah speaking on screen
Deborah?: Thats a great question. One thing,
by sending two rovers, we can go to two distinctly different places. Were
trying to find all about the history of Mars. And by going to different
places, we get more information, rather than just going to one place,
then we could only find out about one particular set of questions. This
way we can, we sort of double up and we get more information.
Stephanie, Deborah, Diana on screen
Stephanie: Great, thank you Deborah and Diana, so
much for being with us today and teaching us a little bit about the science
of the mission. It was really excellent.
F: Thank you.
Stephanie: Now were going to go to some taped
footage of some more women who work on the Mars Exploration Rover Project.
And theyre going to tell you a little bit about what they do. So
lets see that.
Running taped video
Jennifer Harris speaking on screen
Video: My name is Jennifer Harris, and I am the Project
System Engineer for MER. What that means is Im the big picture person.
Im the person who works with NASA headquarters on things like how
far the rover has to drive, how many different spacecraft we need to talk
to when were on the surface. And things like that, to kind of make
the big picture mission work.
Stephanie: Is this the life size?
Jennifer demonstrating rover
Jennifer: Yeah, this is the actual size. And youd
be amazed at how big the rover is. It sit in there on that middle pedal.
Its actually bigger than the pedal when it unfolds its front wheels.
And thats what we do here. We practice driving off the lander. You
can see the [egress legs] that we build that actually unfold with the
pedal. So that helps cover up some of the airbags and some of the other
mechanisms and helps keep the wheels from getting caught as we drive off
the lander.
Underneath here, you can see the airbags. And these,
when we landed, were inflated, and the airbags deflate. And then there
are motors and cords all through the airbags that retract. And so the
airbags all get pulled up underneath the pedals, or towards the pedals
because the lander looks like that when were doing it over there.
And once the airbags get all rolled up, then the lander pedals open up.
And then you can see the rover in there.
And so we landed Mars Pathfinder several years ago.
Now we need to do more science. We need to do a longer mission. We need
to send a bigger rover with more instruments on it.
Jennifer speaking on screen
And our development time is much less than what we
had on Pathfinder. So everythings kind of compressed. And we have
to think about and design a lot of things and get things built and make
sure they work and then get it launched in time to get to Mars.
And so its much more challenging than anything
Ive ever worked on, both from a technical point of view and a people
point of view. There are so many people and communications is something
that we really need to work on, in order to make something like this work.
Joy speaking on screen
Joy: Hi, Im Joy Crisp. Im the Mars
Exploration Rover Project scientist. In my job I lead a science support
team and I advise the project manager as to things that we can do or change,
that will maximize the science return of the mission within the constraints
of the project.
One of the best parts of the project for me is helping
the spacecraft engineering team understand what we know about the atmosphere
and surface of Mars so that they can design a spacecraft that will safely
land on the surface.
Joy demonstrating map
This is a map showing the [Guthan] Crater landing
site, one of our candidate sites. It shows you in color the elevation.
So the blue here is showing you the low area in the crater, and the gray
strips through here, is showing where we have high-resolution images.
The ellipse here is showing where we have a 99% chance of landing if we
target the center of the ellipse, here.
Animated video of rover
The Mars Exploration Rovers carry a lot of instruments
in them and Im watching out for the science of all of these. So
theres a wide range of science thats going on and Im
watching out for all of that.
Helen speaking on screen
Helen: Hi, my name is Helen Mortensen. I work for
MER. Im the Cognizant Engineer for MER and MMIPL. MMIPL is Multi-Mission
Image Processing Laboratory. What I do as a cognizant engineer is I manage
a group of software developers who will be producing products that will
be used in rover operations.
There are six cameras on the MER rover and four of
them have stereo views. That means they have a left camera and a right
camera associated with it. They have put those images on display here.
These are from Mars Pathfinder, but these are examples of what the Multi-Mission
Image Processing Laboratory had collected during Mars Pathfinder.
Images from pan-cam camera on the MER mission
So this view here is the left view from a pan-cam
camera that will also be flying on the MER mission. This is from the left
camera, and this is from the right camera.
Helen speaking on camera
I think my favorite part of my job is being able to
see the images, being one of the first people to see the images. The data
comes down in numbers and we reconstruct it, and were one of the
first facilities to be able to see that data.
And I think the second part is to be able to create
a global view of the data that we receive. Theyre called mosaics,
but this is where we stitch the individual images together and produce
a larger image.
Example of a mosaic
This is an example of one mosaics made of hundreds
of images that have been stitched together. This is a picture of the Twin
Peaks on Mars. Again this is a Mars Pathfinder image. But this is represented
as what well be doing on MER.
Helen speaking on screen
Digital imaging is important to the MER mission because
it gives a representation of what is on Mars. It also allows us to understand
the unknown, to understand what is out there that we havent seen
yet.
Julie speaking on screen
Julie: My names Julie Townsend. Im an
Avionics Systems Engineer on the Mars Exploration Rover Project. Avionics
is-, it delivers the electronics and the software that are used to control
the spacecraft. So what you usually see is all of the hardware and all
of the moving parts. And thats what the mechanical engineers do.
And what my job is, is to work on the electronics and the software that
control all those [moving].
And then I also work on fault protection, which is
probably the most interesting part of my job. It entails thinking about
all the possible things that could go wrong on the spacecraft and how
we can prepare for them. Sometimes to prevent them, and other times to
have the spacecraft react to those problems and keep itself safe.
One of the systems that I work on fault protection
for is the robotic arm on the spacecraft.
Animated video of rover
So thats when were on the surface and
the rover is moving around, and we want to examine some rocks, we have
a sizeable arm that can fold out and theres a bunch of instruments
on the end of it. And I do some fault protection for these instruments
in this arm.
And so things that could go wrong are say, say the
arm bumped into something that its not supposed to hit on its way
to the target that its trying to get to.
Julie speaking on screen
So what our fault protection would do is it would
detect that its hit something it wasnt supposed to hit and
tell it to stop. And in that case, it would just stop and it would wait
for the ground to come in and talk to the spacecraft, so that it could
figure out what went wrong and carefully try to get out of the situation
without doing any damage to the spacecraft.
So I have interest in this, in being an aerospace
engineer when I was in the eighth grade, and at this summer program. And
then that was kind of always my goal. And then when I was in college,
I did another summer program and that was at Marshall Space Flight Center,
and that was the summer that the Mars Pathfinder lander landed. And I
thought that was the coolest thing I had ever seen.
I was-, at the time I was a junior in college and
I was trying to decide what it was that I was really interested in doing,
now that I was really going to be an aerospace engineer. Theres
so many different things that we can do. And I thought that working on
a Mars rover had to be just about the coolest job in the world, and I
could have-, thought that those people who worked on that Mars Pathfinder
rover had absolutely the best job there could be.
And you know what? Now that I worked on one, I think
that I was right. That this is just about the coolest job I could have.
Stephanie, Shante, Jennifer on screen
Stephanie: That was really some great footage. Its
so interesting, they have such interesting jobs. Diane and Deborah talked
to us about some of the science of the mission and now Im joined
by two engineers, Shante Wright and Jennifer [Mindoc] who are going to
tell us a little bit about the engineering of the mission.
And as you can see, Im like hidden by this rover
here. But Shante youre going to talk a little bit about yourself
and then a little about this rover.
Shante speaking on screen
Shante: Hi, my name is Shante Wright and Im
a [inaudible] Systems Engineer on the Mars Exploration Rover Project.
My primary responsibilities will include tracking, service stats, heaters
and temperature sensors throughout the spacecraft. Also I keep track of
the thermal mass so we dont get too heavy and we dont have
any launch vehicle issues.
Another thing that I do a lot of is heater design.
Heater design is really important because we have to make sure that the
actuators and other things on the spacecraft that require heat are able
to stay warm enough to complete their individual tasks.
Now with regards to this item here in front of me,
we were just talking about that, and thats the rover. This is actually
a life-sized picture of-, well actually a life-sized model of the MPF
rover, the joiner.
Shante demonstrating rover
Now, when we talk about a spacecraft, and in this
instance a rover, there are several subsystems that are involved with
making this a reality. Now, one such subsystem is power. Now what you
see here is the solar array. Now this solar array is responsible for providing
power for the rover to function.
Now within this box that we generally refer to as
the warm electronics box, we have the rover battery. Now the battery is
also responsible for providing enough power for the rover to complete
its daily tasks.
Now one item that you saw in the video was the Rock
Abrasion Tool. Now thats not actually shown here on [inaudible]
rover. But thats something thats very important, and thats
part of the payload subsystem. Now, when we talk about cameras, cameras
are so very important and they work in line with the mechanical aspect
of this rover.
Now if you look here, we have a [rocker bogie] system.
And this allows the rover to either go over rocks that are about 10.5
cm in height, or it can actually go around the rock. And thats something
thats determined by the hazard cameras that are generally located
in this area. And so thats a really interesting way in which the
cameras work with the mechanical aspects.
Now, not shown here on the rover electronics deck,
but you did see them in the video, was a large mass. Its a large
mass, its a camera. And its a panoramic camera that gave views
of the planet.
Now we generally refer to that camera as a pan-cam
for short, we use a lot of acronyms, as Im sure youll notice
on our Web site. But its really great, and that the camera gives
us all the different views of Mars and were able to get that information
and look at it here on Earth.
Now one thing that we didnt talk about telecom
wise were the high-gain and low-gain antennas. Those are also things that
you saw on the rover equipment deck. Now with regards to the actual subsystems
here, theres one that I think is particularly important and that
I love the absolute most. And thats thermal.
Thermal is responsible for making certain that everything
within this warm electronics box stays at the operating temperature that
is indeed required.
Stephanie and Shante shown on screen
Stephanie: I had a question for you Shante. Why is
temperature so difficult on Mars? Why is that such a major consideration?
Shante: Thats a really good question. At night
on Mars, it can get as low as minus 105 degrees C. And it is imperative
that everything on the spacecraft is able to survive. Now there are some
things that dont actually have to work during that time, but they
do actually have to survive during that time period so that theyre
able to function for their daily operations the following day.
Now with regards to the subsystems that we discussed,
theres one subsystem that isnt represented here, and that
is propulsion. Now propulsion is really important in the mission, as we
saw in the video, and actually getting it to where its going. We
have what we call TCMs, which are Trajectory Correction Maneuvers, and
this can be a mouthful, so thats why we call them TCMs.
But theyre very important to getting the spacecraft
in the right orientation so that it can continue on the entry descent
landing and finally the landed phase operation of the mission. So thats
a very important subsystem. But its just not shown here. However,
you should indeed stay tuned, because we will have a return sample mission
later on. Im not certain if that will be a 2007 or somewhere around
the like. But it will be around the time frame when you guys are graduating
from college and youre actively involved in that effort.
So make sure that you stay tuned and get information
about that. And propulsion will be key there in returning our sample back
to Earth.
Stephanie: Now Shante, this is obviously not one of
the Mars Exploration Rovers. This is Sojourner. Can you give us any idea
of whats the same and whats different and how do they differ
in size?
Shante: Wow, thats a very good question. When
we look at the subsystems, all the subsystems are indeed represented here.
However, there are a lot more instruments on Mars Exploration Rover. Now
whats really interesting is, this rover is really tiny in comparison
to what were actually going to send to Mars this time.
The rover that were sending to Mars is somewhere
along the lines of just under 2000 kg in weight. And this one was way,
way below that. Now with regards to the size, this rover is really small.
The one were sending is going to be absolutely huge. As you saw
in the video, it has various deployment mechanisms that will allow it
to reach its actual size. But when it actually starts, its going
to be small enough that it can fit on the base pedal of the lander.
Now whats really neat here,
Stephanie: And then its legs kind of like spawn out
like that, right?
Shante: Yeah its really cool.
Stephanie: Because I know Jennifer talked about that
being quite interesting, that such a large piece of machinery can compact
itself into such a small lander.
Shante: Yes. And thats where mechanical is really
important. Because all those deployment mechanisms, all those actuators
or motors are really important in allowing this spacecraft to fit into
that very small space. Now you notice here there arent a lot of
instruments on this particular rover. For MER its filled with instruments.
A lot of the cameras were actually on the lander for
NTF. And theyre actually on the rover in this instance. So thats
one of the primary differences, aside from just the tremendous difference
in size.
Stephanie: Thank you so much, Shante. That was so
great. Now were going to take a minute and talk with Jennifer Mindoc,
whos also an engineer. She does something a little bit different
though. You do a lot of testing. Can you tell us about that a little bit?
Jennifer speaking on screen
Jennifer M: Sure. My name is Jennifer Mindoc and Im
an Avionics Systems Engineer, as you saw Julie in her video earlier talked
a little bit about that. I have a couple pictures if you could show the
first slide, please.
Slide: MER Avionics
MER Avionics are basically the electronics on the
spacecraft and the software that controls the spacecrafts function.
So as you see, theres a figure there, and that represents the electronics
that are inside the spacecraft controlling what is going on. So I refer
to it as the brains of the spacecraft.
Slide: MER Rover
Next slide, please. And here is a picture of the,
our rover the MER rover. And that little arrow is pointing actually underneath
that, its pointing to the solar arrays, but underneath the solar
arrays, are where the warm electronics box actually is. And thats
the location that you dont usually pay a lot of attention to, but
its really kind of the mastermind behind whats going on on
the spacecraft.
Slide: TESTING IS IMPORTANT!
And then next slide, please. Here is a picture about
a lot of what I spend my time doing, which is testing. And in the bottom
corner is the integration and test Test Team, and the lab that we work
in where we do so much of the important testing for the mission. And then
in the upper corner is a picture of some practice tests where the rover
is practicing actually crawling off the rover.
Jennifer M speaking on screen
But one thing thats really important about the
testing is that in the lab that I work in, is that this is the first place
that the flight software and the hardware actually come together. So we
see how they perform for the first time.
Before this, the design has taken place and the hardware
has been built, the software team is working on coming up with their code
and then we actually put them together for the first time in this lab.
So its really exciting to see as we build, starting from zero where
we have one, maybe one electronics card and build that up into a box of
electronics cards and then make sure that they all work together. And
then were using [a byte] software to test what were actually
going to use on the mission.
So we just build it up piece by piece in order to
make sure that little by little, everything works together and does everything
as it should. And as the testing continues, we build up so that we have
the system and we can test the different parts of the mission, the cruise
phase while were getting to Mars, then the EDL phase while were
actually going through the atmosphere, and then we can test things while
were landed on the surface, and practice that.
So the important thing is that were practicing
as much as possible to make sure that weve rehearsed enough and
we know how the system performs.
Stephanie, Shante, Jennifer on screen
Stephanie: Thats great, Jennifer, Shante, thank
you. I know we have a lot of questions from out chat room. Cathys
giving me looks so lets take some of those.
Cathy: We definitely have a lot of wonderful questions.
One question is coming from Allison whos in San Jose who wants to
know a little bit about the education you did and whether its possible
to get involved with research without having a Ph.D. So maybe Shante you
could talk about that a little bit.
Shante speaking on screen
Shante: Yes it is indeed possible to get actively
involved in research without a Ph.D. In fact, as a student can become
very actively involved. We have lots of student programs throughout NASA
that really encourage students to really get their hands in to the Mars
dirt, and get a lot of research work done. Because were going to
an environment that were not especially familiar with. And its
really important that we do a lot of research and that research is performed
by people at all types of education levels, even our students that come
in for the summer.
Stephanie, Shante, Jennifer on screen
Cathy: Great. Ive got a question for Jennifer.
It comes from Angelica in Miss Petersons Fourth Grade. She wants
to know that when you launch the Mars rovers, will you launch them at
the same time?
Jennifer speaking on screen
JenniferM: No, actually were going to be launching
one in May of next year and then launching the following one in June of
next year. And that way we can get to different spots on Mars as the scientists
have talked about earlier, we like to go to different locations. So that
really allows us to get to the different places on Mars.
Stephanie, Shante, Jennifer shown on screen
Cathy: Great. Ive got another question. Chris
from Hayworth wants to know how the rovers engine will be powered.
Shante, could you talk about that?
Shante speaking on screen
Shante: Yes, thats really cool. I especially
like that type of thing. Thats actually propulsion. Now with regards
to the engines, we have a main engine and we have, actually we have, we
actually just have [fluster clusters] on this mission since Im thinking
about something else.
We have two large propeller tanks and we have [fluster
clusters]. Now when we talk about a main engine, its not actually
on the spacecraft per se, its actually on the launch vehicle. The
launch vehicle will actually get us into our initial approach and then
well have flusters that help us with the orbit trajectory changes,
so that we can get on target to where we actually want to go.
Back to Stephanie, Shante, Jennifer
Cathy: Great. And Ive got another question from
Elizabeth whos a sixth grader in Apple Valley, California. She wants
to know a little more about the kind of information that NASA will be
collecting from MARS. Jennifer?
Jennifer speaking on screen
JenniferM: Oh gosh, all kinds of information. Well
be taking science data from all of the science instruments that well
be using and so the scientists will be able to analyze the geology and
the climate of Mars. Well also be, at the same time, gathering engineering
data. So well be able to learn about how well the science instruments
are performing and also how well our rover is performing itself.
So well be measuring how our motors are performing,
how our wheels are working and so basically science and engineering will
both be gathering a lot of data, so we can actually figure out as much
about Mars and our own system that we can.
Stephanie, Shante, Jennifer on screen
Cathy: Thats great. Ive got another great
question from Ellen in Westover who wants to know if like working at NASA
as a woman, she wonders what barriers there are to becoming an engineer
or what the good parts are and what its like to get a job at NASA.
How does being a woman help you or hold you back? Shante:
Shante speaking on screen
Shante: Well that is indeed a great question. Actually
I dont see it at all as a hindrance. I really dont see it
at all as a problem. You just really have to be very motivated at anything
you do, whether its being an engineer or being a business person.
You really have to be motivated, and you cant let gender stand in
your way, even if someone chooses to make it an issue. You make it a non-issue
and you move towards achieving your goals.
I absolutely love working at NASA. I decided I wanted
to work for JPL NASA when I was in fifth grade, and I just put myself
on the path to make that happen. And I really dont see any barriers
because I see a lot of women, like the women that were presented in the
beginning of the video, and throughout the video, that have attained just
incredible things. And I know that I can do that, because I see women
ahead of me that have already done it.
Stephanie, Shante, Jennifer on screen
Stephanie: Just like you guys may be to some of our
young women in schools who are interested in science and engineering.
Jennifer, why dont you answer that too? How do you feel about
Jennifer speaking on screen
JenniferM: Sure. Ive never felt like there was
really every been an issue with me being a woman working at NASA. Its
always just been you showing that you can do the things that youre
asked to do, and you work as hard as you can, and you show your abilities.
And thats really the most important thing that matters, as long
as youre just showing that youre dedicated to what youre
doing and you try as hard as you can. And it doesnt matter if youre
a woman or a man.
And Ive never felt like there was any difference
in assignments that Ive received or any tasks, just because Im
a female. Its always just proving your abilities, basically and
just working as hard as you can. And its an absolutely fabulous
place to work and its amazing the things that go on within NASA
and at JPL.
Stephanie, Shante, Jennifer shown on screen
Stephanie: Now as far as science and engineering go,
were going to, in a minute, talk to a-, or see some tape of some
women who are not scientists or engineers. But before we get into that,
I know you guys have some very clear advice for young women or men who
are interested in pursuing careers in science, engineering, technology,
things like that. Could you just tell us what that is right now?
Shante speaking on screen
Shante: Well, I think it is really, really important
to get actively involved in math and science in the classroom and outside
the classroom. Its really important to get yourself in a position
to take the high-level math courses when you get into high school and
you get into college.
Now when youre in junior high, you may think
its not important to take the algebra class or the geometry class
if its offered, when in fact it is very important. Because when
you are in junior high, you are taking the initial steps that are going
to lead you to the career of your choice. If you choose not to take the
challenging math classes, then youre choosing to put yourself in
a position to not have the career that you want, especially if its
in math and science.
I know most of the women and men that are in engineering,
took these classes very early on and it really helped them when they got
to the higher level math in college. And so it is really important to
take as many math and science classes as you can at a very early age.
Stephanie speaking on screen
Stephanie: Thanks, Shante. Okay, well this has been
so interesting. I really appreciate you teaching us a little bit more
about the engineering of the mission. But now, were going to take
a minute to hear about some women who perform jobs that arent related
to science or engineering, but theyre still very important to making
the mission with the Mars Exploration Rover mission successful. So lets
hear about them.
Taped video of women who work on Mars Exploration
Rover
Cathy speaking on screen
Cathy B: My name is Cathy Born. Im a machinist here at JPL.
Ive been making parts for the rover for about six months now.
Video of rover landing on Mars
The most interesting thing and the most simplest probably
was, this is a sheer pin its called. The rover, as it comes down
into Mars and breaks through the atmosphere, it will be traveling at a
pretty good rate of speed. And depending on the angle that it lands, this
pin, if it lands to where this is the supporting thing between the ground
and the rover, this can have up to 5000 pounds of pressure put on it.
Its a good feeling knowing that what I made
could be what saves it. But weve got one in 360 chances of it landing
on this particular pin. So, its pretty incredible though. I sometimes
I get a blueprint and therell be a dimension missing, and I cant
just pull one out of the side and assume. Thats not our way here.
Weve got to know.
Laura speaking on screen
Laura: My name is Laura Berwin, Im a graphic
artist, and I work for JPL, and I create art that supports the Mars missions.
I think the graphic art aspect of these missions is important because
the Web is the medium that most people are finding out about these missions
on, and theyre going to these sites to get information. And when
they go onto these sites, the Web-, the sites need to look pretty and
they need to look exciting, so that people know how exciting these missions
are and how much information that we can get from these missions.
One thing that Im working on right now is Imagine
Mars. Imagine Mars is a Web site that will be like a portal or a resource
for kids and teachers to put in their artwork or music or projects to
give people a better idea of what they think that Mars will be like in
the future, and what a habitat would be like.
Video showing Web site and Laura working with it
And I just came up with a design for one of the Martian
habitats, and this one we decided to put in a couple of crazy blimps and
so houses that were going to live in may, in the mountains in Mars
and some VW-type cars that would drive around the surface there.
Whats challenging about this job is that Im
not a scientist and I think I tend to go towards making things look pretty
and fun and wanted to make things look colorful and kind of outrageous.
I must remember that we have to keep things like scientifically accurate.
We designed these buttons to go into the different
sections here: Extreme Planet, Follow the Water, [inaudible]. Theyre
supposed to be visually appealing but at the same time to give you an
idea of where youre going in the site and something about each section.
Well I find space exploration really interesting and
I like learning about this stuff when I come to work. And I feel like
my job is important and that its meaningful.
Connie speaking on screen
Connie: My name is Connie Gennaro and Im the
Outreach Coordinator for the Mars Exploration Rover mission. I work here
at the Jet Propulsion Laboratory. And an Outreach Coordinator does all
kinds of different things. I set up visits for the public, for schools,
for kids coming. I get to meet a lot of interesting people here.
Connie demonstrating rover
This little guy was used by the Mars Pathfinder mission
to decide whether they needed six or eight wheels to go. So they would
test this one and they found out that if it has eight wheels, that they
were actually able to do the mission with six wheels. So this is a real
prototype for the Sojourner mission.
Well, one of my very favorite things to do is to roll
the rover over children, and having them actually experience a rover real
close up and personal. And they walk away saying that they actually touched
a rover and that it rolled over them and its just a thrill for them
and its more of a thrill for me to be able to reach them in a real
tangible way.
So I think my job is important to the MER mission
because Im the one who brings the knowledge of the mission out to
the public. And so kids in school and just the regular folk out there,
actually get to learn about what were doing.
I am first-generation American. My parents were Mexican
and actually I was the first generation to actually go to school. And
so this was a real big jump, I think, for me. And being from a very, very
traditional Mexican-American home where girls usually maybe finished grade
school, go finish the high school, but theyre expected to get married.
Theyre really not pushed to go to school or university. And so it
was really breaking a mold in my family.
I just really want to tell everybody out there that
you guys need to pursue your dream. Pursue everything. Youre your
own limit. And we are in a great country that if you want to pursue something,
it doesnt matter what your background is, you can do it. You can
do it.
Stephanie speaking on screen
Stephanie: Wow, what powerful words. Thank you so
much for watching that and thanks again to the women who helped to make
these videos happen. Because you in our audience have so many questions
about Mars, weve brought back Diana [Blaney] whos going to
answer some more questions for us. Cathy?
Stephanie and Diana shown on screen
Cathy: We do have some wonderful questions. Annie
from Ellens class in Westover, CT, asks how does a robot deal with
weather conditions on Mars such as sandstorms?
Diana speaking on screen
Diana: Well, the atmosphere on Mars is a lot thinner
than it is on Earth. And how it does it, is it tries to-, Im sorry.
It tries to-, it basically designs to work around the sandstorm. We know
how much that sand is going to be in the atmosphere, its called
dust. It falls out on a daily basis. So the power system that you were
talking about that was designed with the solar panel, has to be designed
big enough that the sand comes in.
Joy mentioned earlier that we try to understand whats
going on Mars. Sandstorms is one of those things we understand, so we
try to send the rover to Mars, places and time when we dont think
theres going to be sandstorms. So thats-, we try to plan and
we try to design to counter, survive whatever we encounter.
Stephanie and Diana shown on screen
Cathy?: Great. Weve got another question from
Tyler whos a kindergartner at Apple Valley, CA. And he wonders how
far away is Mars?
Diana speaking on screen
Diana: Mars is 1.5 astronomical units from the Sun.
And its basically the distance, the Earth is 1 astronomical unit.
So, and then Mars is 1.5 times. So if you kind of thought about it and
took three steps, took two steps for the Earth away from a point, and
one step more, that would be where Mars is.
That makes Mars a lot colder, which is why theres
all this concern about the power, the heat power and the thermal system.
Mars is very, very cold at night and so you dont want the electronics
and things like that to be freezing.
Stephanie and Diana on screen
Stephanie: And also if you think about it, its
going to take about seven months for the rovers to get to Mars traveling
at extremely high speeds.
Diana: Right. So super, super, super far away. An
astronomical unit is 96 million miles.
Stephanie: Its hard to even imagine.
Diana: Yeah.
Stephanie: Yeah. Do we have any more?
Cathy: I think we do have actually one more question.
This ones coming from Gerald Burns, a sixth grader in Apple Valley,
CA. And he is asking whats it like to be a NASA scientist studying
Mars?
Diana speaking on screen
Diana: Its fun. Its fun. You get to do
a lot of different things. This is a real exciting time in Mars science,
because we have so many Mars missions. What we thought about Mars five
years ago, and what we think about Mars is totally different because of
Mars Global Surveyor. Weve got new pictures, weve got new
data, and every two years now, were launching a mission. And its
kind of a real experience of discovery.
These are going to be the first time were going
to land on the surface of Mars with really sophisticated scientific instruments.
And were going to learn so much that we dont know. This is
the time. Its so exciting.
Stephanie and Diana speaking on screen
Stephanie: Yeah, Im so excited to be alive now
and get to find out this stuff. I think we have one more.
Diana: Okay.
Cathy: Weve got a great question from Laurie
in Hayworth who asks about the kinds of pictures that the rovers
going to collect.
Diana speaking on screen
Diana: The rover is going to take color pictures in
different filters, theyre called wavelengths. And we can use that
to help figure out. In addition, its going to take something called
spectra, which are in wavelengths that the eye cant see, that tells
you how things are made up. So eventually were going to be able
to make maps of what the composition of the surface is and compare that.
Helen had mentioned that theres two cameras.
Theres a left eye and right eye. They act like your eyes do so you
can get depth. So well be able to measure how far things are apart
and the stereo separation and the different sizes of rocks. And so because
the rover moves every day, every day its going to see a different
place, and weve got to take really good pictures so we can figure
out how to get from point A to point B through the rocks, over the hills,
everything.
Stephanie and Diana on screen
Stephanie: Thank you so much for coming in here and
answering some more questions for us. And for any of you that asked questions
that were not answered, please know that we will answer them online in
the next few days and you can go back to the Quest site and find your
question and it will have an answer to it. And you might be answering
some of those too, so thatll will be fun.
Diana: Yeah, that would be fun.
Stephanie: Now, all of the women weve seen today
were at some point in their lives students. And were lucky enough
to have a student, Daisy Uribe, who is interested in science and engineering
and actually was part of the [Lapis] program. And shes going to
tell us a little bit about what Lapis is.
Daisy speaking on screen
Daisy: Well basically the Lapis program is for high
school students who are interested in Mars exploration. Its 16 students
out of, well in the United States and what they do is they test the Mars
prototype [Fido]. Right now the program or the name of the program has
been modified and its Athena Student Intern.
So the program basically what we do is what scientists
do, just students do it, instead of it being in Mars, we do it at a different
test site. But we do the same exact thing.
Stephanie: And what was that like? Did you really
feel like a scientist?
Stephanie, Diana, and Daisy shown on screen
Daisy: Actually, yes I did. I felt like such a scientist
because you are actually working with scientists and youre doing
the work that they do.
Daisy speaking on screen
Youre having big meetings and youre having
these breakdown [commutes] to very-, its very difficult but its
a really great experience and it is a lot of fun.
Stephanie, Diana, and Daisy shown on screen
Stephanie: And I remember you mentioned before when
we were chatting that you had problems with temperature as well when you
were doing your mission. But they were different than the problems on
Mars.
Daisy speaking on screen
Daisy: Well you see Mars, as is the Mojave Desert,
which is where our test site was, and it was very, very hot. So the problem
that we had with the Fido was that when if we used a motor too much from
one of the wheels that we needed to dig a trench, they would explode,
or it would just go off, and thats it. Our machine was, it would
have failed.
So what we had to do is we had to take a third of
whatever it was that we were going to do, which was 300 revolutions, and
we were only able to take a third of those, which is 133, to do. And in
order for us to dig that trench. So we only got a third of what, of those
300 revolutions, and it, we still dug a pretty big trench. It wasnt
what we wanted, but if we wouldnt have taken a third of that, then
our mission wouldnt have been successful.
Stephanie, Diana, and Daisy shown on screen
Stephanie: So you solved a real science problem
Daisy: Yes.
Stephanie: ...with your mission and thats excellent.
So are there other ways that students could get involved besides the Athena
Student Intern Program?
Daisy speaking on screen
Daisy: Yes, there are two other ways. You can do the-,
its called the Mars Student Imaging project, which its fifth
graders to 12th graders. And what they do is they, like real scientists,
with scientists they image sites on Mars.
tephanie: Thats with the Odyssey mission cameras?
Right.
Daisy: Yes. And the other program is the Imagine Mars,
which is for younger students who want to also do Mars exploration, and
what they do is they kind of go out in their community and they get involved
with Mars and they kind of use art and technologies to explore Mars.
Stephanie, Diana, and Daisy on screen
Stephanie: Yeah, and I can talk just a little bit
more about the Imagine Mars project. Its more for younger children,
and also I just want to point out that were talking about three
ways you can get involved in Mars exploration or any kinds of NASA programs.
Stephanie speaking on screen
But theres lots more than just three ways. And
you can find some of them on the Web site, on the Quest Web site, are
links to the projects were talking about today and also you can
go onto any of the NASA sites to find out more about education programs.
But just for a minute, about the Imagine Mars program,
thats something for K through probably sixth grade and its
a way for them to work with their own community, see what things are good,
what things are bad and then decide what kind of a community theyd
like to build on Mars. And they think a lot about the humanities, what
kind of art would we have if we lived on Mars? What kind of music would
we have? What kind of buildings would we have? Its a really creative
way to integrate science into a classroom or a Boy Scout troop or a Girl
Scout troop. So thats a pretty neat program too.
And I think we have some questions for Daisy. Theres
a lot of students who are interested in what youve been doing, and
I think well take one of them now. Cathy?
Stephanie, Diana, and Daisy on screen
Cathy: Yeah, well weve got a question about
Daisy, what do you plan to do when you finish high school, because this
is your last year, youre a senior, right?
Daisy speaking on screen
Daisy: Yes, Im a senior in high school. What
I plan to do is to go to college and go into the science field. I want
to become a scientist, possibly an engineer. Im still not sure.
Im still undecided, but all I can tell you is to take a lot of math
and a lot of science. That is what you should do. Its really fun,
its great. And youre going to have such a great time.
Stephanie: And I think that Daisy we might have some
slides that show pictures of you really getting into the act, doing, on
Mars. Is it possible to queue those?
Great I think we have some slides. Maybe you can tell
us a little bit about those.
Slide: Core operations team at JPL
Daisy: Okay. This is where all the students were,
its the core operations team at JPL. This is where we did our commands
there, and we had our, there was a room and we had our big meetings and
thats, that is what oh, that is where our work space was for two
days. And that is where we talk, the scientists are there. You can see
scientists and students and all these big screens, these big plasma screens,
which showed all the information and all the commands [that we sent out]
and information and the pictures that we got back.
Slide: In the field at trench
Next slide. The next slide is when we were out in
the field, when we were looking at the trench we had dug, which was our
mission to dig a trench. And that is where all the students are and this
is in the Mojave Desert, this is, was our test site. This is after the
field test. We wanted to see what we had accomplished and wanted to see
what work we did.
Slide: Picture of Fido
Next slide. Oh, this is a picture of our buddy, the
Fido. This is well our prototype that we worked with. This is what we
commanded and hes the one that goes into Mars and he explores and
he does all of that.
Daisy speaking on screen
Stephanie: Great, thank you. Here is another question
for you Daisy. We wonder what was your favorite part about working with
the rover?
Daisy: My favorite part? I think my favorite part
was getting to know all the people that you basically had teleconferences
with. And meeting, actually meeting them, because you have a voice but
you dont have-, you dont see anybody. And what we did is we
all got together and it was really fun. There were all these teenagers
and then all these scientists. And it was a really great experience because
a lot of the scientists-, you assume that because theyre big shots,
theyre going to be kind of mean to you or theyre going to
be like "oh Im better than you." But no, they were really
nice, and they were really great people and they helped us out a lot.
And thank you to all of them because it was a great experience.
Stephanie, Diana, Daisy shown on screen
Cathy: And I have one more question. If you could
tell us a little more about ways to get involved with just robotics. If
there are any robotics competitions that students can do?
Daisy speaking on screen
Daisy: Yes, there are two robotics competitions. One
of them is [dot bow] I believe, and the other is called First. And these
are all robotics competitions. If you dont want to go into Mars
exploration.
Stephanie, Diana, Daisy on screen
Stephanie: And theres lots more information
on those education programs on the Web site as well. So, thats great.
Okay, well, Im sorry, but were just about out of time. This
has been so much fun and were so grateful. Thank you to our panelists
visiting here. Theyre all off over there. And thank you Daisy, so
much for sharing all your experiences with us. That was really special.
Stephanie speaking on screen
We also want to thank the JPL video crew for their
time in putting some of this video, these pieces together. We want to
thank the JIT studio because they made this happen and were happy
to be introducing everyone in our audience to so many great women.
Finally, thanks for being here for all of you who
tuned in. Youre why we did this today. And we really hope that youre
able to pursue your dreams, whether they be in science or engineering
or art. I think it was said best, that you can do it. I think Connie Gennaro
said that. And we all support you.
So thank you so much. Dont forget to fill out
the survey. Theres a survey on this, the Quest site that wed
love to get some feedback so when we do another one of these, we can incorporate
what you thought was good and better.
Okay. Thank you so much. And we will talk to you again
soon.
Diana: Bye.
