Eileen Collins Answers Your Questions on Orbit
In December we were invited to interview Commander Collins in a Shuttle
cockpit simulator at the Johnson Space Center in Houston, Texas. The video
and text versions of the interview are linked from Eileen's profile. During
our discussions, she offered to attempt to answer some questions from our
student constituents during her time on orbit as time permits.

We invited participants in the Female Frontiers project to pose
questions from which your Student Ambassadors selected the best.
These were then be passed on to Eileen.
The following is a text version of that transmission:
Commander Collins from the Columbia Orbiter:
Houston - Columbia
Mission Control at Johnson Space Center:
Go ahead
Commander Collins from the Columbia Orbiter:
I'm back and ready to answer some
Internet questions for the Ames site. If you have a few minutes
here, I'll come.
Mission Control at Johnson Space Center:
Please, the floor is yours.

Commander Collins from the Columbia Orbiter:
Okay, the first question was about building Chandra and what the most
difficult obstacle for it to overcome is; and how you can overcome the harsh
elements of space.
The short answer to that is: Chandra has heaters, radiators, sun shades
and thermal blankets. There is also a small vent valve that was opened
while CHANDRA was in the Columbia payload bay, and there's a larger vent
valve that will be opened here over the next few days during the sequence
of getting Chandra into its higher orbit. Those vent valves are designed
to keep contamination away from the sensitive instruments.
The next question is: What is it that Chandra hopes to accomplish,
and how it will benefit us here on Earth?
A good way to start that answer is to look at the spectrum of light: there's
infra-red, there's visible, ultraviolet, X-rays and Gamma rays, and there's
also radio. Chandra is focusing on the X-ray part of the spectrum, and
we have other observatories that look at other parts of the spectrum.
Chandra is the third of four great observatories. By studying X-rays we
hope to learn more about the world that we live in by unlocking some of
the secrets of the universe. For example, Chandra will study black holes,
neutron stars, quasars, and other high-energy objects. Also, it may help
us to search for the missing map of the universe.
The next question is: What was the view like outside during the
ascent?
Well, since we launched around midnight to one in the morning east coast
time, it was quite dark, although while the boosters are firing and the
main engines are firing, you see flashes of light in the windows. That
was actually my third launch and my third night launch, so I don't have
any way to compare it to a day launch, but maybe some day I will.
The next question is: How many hours of work do you do, culminating
in a launch?
Wow! The answer to that for this crew is that we've been training for
16 months. Although occasionally crews are assigned to missions as late
as 9 to 10 months before a launch. So it really does vary on how much
work it takes to set up to prepare for a launch. The long answer to that
question is: astronauts are selected many years before they get assigned
to a flight. From the time you begin your astronaut training you can fly
anywhere from two years to as long as five to eight years before your
first flight.
What else on orbit besides your training and preparation for maneuvers
do you do?
In this flight, obviously after the Chandra deployed, we've had many secondary
experiments. They've all been very interesting. Some of the ones we spent
the most time on are the SWUIS telescope which is a Southwest Ultraviolet
Imaging System. We also have some experiments where we're growing spores
and plants and studying how they change in microgravity. We have a ham
radio on board, and we have a high-definition T.V. Camera. We have a hinge
experiment which is studying the future of solar array designs. We're
also taking many pictures of the Earth and specific, certain targets that
were asked for by scientists.
What kind of things do you do in your free time?
We haven't had very much free time on this mission. I would have to say,
we take pictures of the Earth or look out the window. It's tough to have
much free time on a five-day flight because there is so much to do. We've
been working pretty hard, but we enjoyed that too.
The second-to-last question I'll answer: What was your favorite
part of preparing for the mission?
My personal favorite part of preparing for the flight was training in
the Shuttle Training aircraft and the T-38 airplanes that we use for space-flight
readiness training.
What are some of the things that you will bring up to space?
There were many things that we brought up. I'll just mention a few. The
Chandra operations control center which is controlling the telescope is
flying a banner on this flight. The Sunnyvale Air Force Squadron that
controls the Chandra's upper speed booster, which is also an integral
part of this mission, is flying a banner on this flight. We also have
flags from several countries.
There are several other questions here: some short ones I can finish
up with.
One question: You've studied and taught math. Do you still use
math as a space shuttle pilot and commander.
The answer to that is yes, very much so! We use math all the time in our
every day life as shuttle astronauts. When you're in school it's important
that you study algebra, trigonometry, geometry and calculus. After you
use it enough, you'll be able to do math quickly and in applications to
the parts of spaceflight.
Here will be the last question: When you are in space what do you
miss most about being on Earth?
Mission Control at Johnson Space Center:
Eileen, thanks for those answers. They were very illuminating and it's a
good way to close, and patch our thanks over to Steve for answering those
(another set of questions).
Commander Collins from the Columbia Orbiter:
Okay, we'll do that
