And now, here are our NASA experts to answer your questions.
[ LisaShore/JSC - 22 - 10:02:51 ]
RE: [Kelly_CrestonMiddleSchool] Lisa
Shore, Have you ever lost a shuttle? If so, what was it like to know that
you couln't find the shuttle? Why did you lose contact? 8th grade
Hi Kelly! We've never lost a shuttle. We have lots of stations and satellites
to track them and the shuttle is pretty big. We have lost a satellite
for a few hours before.
[ BillFoster/JSC - 23 - 10:03:09 ]
RE: [Ellen8_CrestonMiddleSchool] Dear
Mr. Foster, How difficult is it to understand what the astronauts are
saying in space?
Ellen, Depending on what is happening at the time, it can be easy or difficult
to understand them. The quality of the voice is generally excellent, but
there are frequently many other voices from other loops in your headset.
Generally, when the crew is talking, we try to remain silent so we can
pay attention to what they say in case we need to take some action, but
there are times when it gets to be a challenge to choose the right voices
to listen to. Thanks for your question.
[ TimTerry/JSC - 24 - 10:03:15 ]
RE: [AshleyWMS] Mr. Terry, Can you
explain some of the missions?
Hello Ashley. Most of the missions are related to the assembly of the
International Space Station. We're taking various pieces of the Station
to space and putting them together with pieces that are already flying.
There are still a few missions not related to the Station, most of which
are used to collect scientific data about the Earth or our galaxy.
[ MikeMoses/JSC - 25 - 10:03:49 ]
RE: [AshleyWMS] What is a typical
day of work for you?
Ashley, a typical day of work is either an office day, spend studying
and reviewing procedures, preparing for upcoming flights, or a sim day.
During sims, we go to the control center and "practice" a mission.
[ RobertDempsey/ISS - 26 - 10:04:29
]
RE: [AshleyWMS] What is a typical
day of work for you?
For me (Space Station flight controller), typical day usually means lots
of meetings as we plan our missions. Plus we do a lot of training and
testing. Tends to be a pretty busy day.
[ LisaShore/JSC - 27 - 10:04:54 ]
RE: [AshleyWMS] What is a typical
day of work for you?
Hi Ashley! Welcome to the chat. My typical day consists of checking my
e-mail, going to a few meetings, preparing for a sim or flight and occasionally
simming or flying.
[ LisaShore/JSC - 34 - 10:06:31 ]
RE: [MrsHestersClass] How do you
keep track of the shuttle in space?
Hi Mrs. Hesters class. We keep track of the shuttle with a network of
ground tracking stations and with tracking satellites.
[ TimTerry/JSC - 35 - 10:06:32 ]
RE: [AshleyWMS] What is a typical
day of work for you?
A typical day for me would be scheduling and preparing simulations for
the flight control teams or actually conducting those simulations with
the crews and flight controllers. It takes a lot of preparation to challenge
these experts.
[ RobertDempsey/ISS - 36 - 10:06:57
]
RE: [AshleyWMS] What is your predicted
date at which people will get to live in space? (besides the space stations
we currently have)
WEll people already live in space for short periods - but if you mean
the continuous living on the space station - around October or November.
[ BillFoster/JSC - 37 - 10:07:14 ]
RE: [Stephen] What does MMU stand
for
Stephen, MMU stands for Manned Maneuvering Unit, which was used in the
early days of the shuttle program to expand the movement of astronauts
during EVAs. There were some spectacular moments with astronauts out away
from the shuttle, or attempting to grapple a satellite with a special
tool. these are no longer used, but a smaller cousin of them, called the
SAFER, will be used by astronauts that must get further from the shuttle
or station during assembly operations than a tether will allow. These
will be for safety only and not a primary means of moving about. Thanks.
[ LisaShore/JSC - 40 - 10:07:56 ]
RE: [NateJared] How long does it
take to lauch a shuttle?
Hi Nate and Jared. The part of the launch where the main engines are on
takes about 8 and a half minutes. We perform another maneuver about 45
minutes later to keep us in orbit.
[ MikeMoses/JSC - 42 - 10:08:00 ]
RE: [Stephen] What does MMU stand
for
Stephen, the acronym MMU actually can mean a few things. It commonly refers
to the Manned Maneuvering Unit. That was a big "backpack" that astronauts
used when outside the shuttle on spacewalks. It allowed them to fly outside
the shuttle payload bay to retrieve satellites. MMU can also mean the
Mass Memory Unit, which is essentially a computer hard drive that holds
the shuttle software.
[ TimTerry/JSC - 48 - 10:08:46 ]
RE: [TERRA] DO YOU LIKE WHAT YOU
DO?
Most of us will probably jump at the chance to answer this one. I personally
love what I do and feel very fortunate to contribute to our presence in
space. The variety of the jobs and the compliment of talented people makes
the work more enjoyable. I wouldn't know what else to do if I didn't work
here.

I have to agree. There is a great deal of challenges and variety in our
jobs. It is also great to figure out how to do the things we do for the
first time.
[ LisaShore/JSC - 57 - 10:10:38 ]
RE: [Samantha] lisa what is exactly
MCC
Hi Samantha. The MCC is the Mission Control Center. It's the building
here in Houston that we control the Shuttle and International Space Station
from. Most people think of the MCC as the front control room they see
on TV.

RE: [TERRA] MR.MOSES-HOW MANY WORDS
A MINUTE DO YOU HAVE TO BE ABLE TO TYPE TO HAVE YOUR JOB?
Fortunately, not too many. It helps if you can type fast since we spend
a lot of our time on the computer, but no speed is required.
[ MikeMoses/JSC - 60 - 10:11:22 ]
RE: [Dee] Mr. Moses. Did you have
any career choices, other than the ones you listed in your profile? (Vet
and astronaut) What other career could you have gone into with your education?
Dee, I went to school with plans on becoming an astronomer. I spent a
lot of time looking through telescopes. But one day, instead of going
to the observatory, I went to help a friend test fire a rocket engine.
From that point on I knew I wanted to work with rocket propulsion.
[ TimTerry/JSC - 64 - 10:12:18 ]
RE: [Kelly_CrestonMiddleSchool] Tim
Terry, What was the most interesting mission that you had to train a crew
for? Who was in the most interesting crew that you ever had to train?
8th grade
Hi Kelly_CrestonMiddleSchool! Probably the most interesting mission was
STS-88/2A, the first International Space Station assembly mission. The
mission was flown in December, 1998. To answer your other question, all
crews are interesting in many ways. It's fun and challenging to bring
folks with many backgrounds and expertise together and help them perform
as a team. The STS-88/2A crew was as interesting as any I've trained.
[ MikeMoses/JSC - 65 - 10:13:04 ]
RE: [TERRA] MR.MOSES-HOW MANY WORDS
A MINUTE DO YOU HAVE TO BE ABLE TO TYPE TO HAVE YOUR JOB?
I can't type very fast - it's not really a requirement. You have to be
able to type well enough to get your job done but the actual stuff we
do in mission control doesn't specifically require fast typing skills.
[ LisaShore/JSC - 66 - 10:14:51 ]
RE: [MrsHestersClass] What is a typical
shift like?
A typical shift on console starts with what we call a handover from the
previous team. We talk to them for about a half hour and find out what
has been going on since we left. Then the Flight Director holds a conference
on the voice loops and everybody tells what's going on in their area.
After that you spend the time planning for the upcoming activities like
a maneuver.
[ BillFoster/JSC - 67 - 10:15:18 ]
RE: [Kelly_CrestonMiddleSchool] William
Foster, Have you ever lost contact with a shuttle? Were you worried when
it happened? What was the reason for losing contact? 8th grade
Kelly, We do lose communications with a shuttle sometimes for a variety
of reasons. Sometimes the shuttle maneuvers off the best antenna to talk
to the TDRS or ground station, sometimes we have radio interference from
a transmitter on the ground. We simulate this a lot, including equipment
problems on board or on the ground causing the problem. We have detailed
procedures to follow to recover comm. This has never been a major problem,
and most times it happens we know in advance it is a possibility.
[ MikeMoses/JSC - 71 - 10:16:29 ]
RE: [AshleyWMS] What is the hardest
thing you have done so far for Nasa?
The most challenging part of my career at NASA happened for me during
the last shuttle mission, STS-99. The payload was making a radar map of
the Earth and had a failure that caused us to use more propellant than
we planned on. Since I'm a PROP flight controller, that means it's my
job to track this usage and try and find a way to let the payload customer
continue mapping the Earth to get full coverage. The entire PROP team
worked hard and managed to get a full mission.
[ RobertDempsey/ISS - 73 - 10:17:16
]
RE: [StephenGagne] Why is NASA tryingto
make cheaper robots?
Stephen, well, it is very expensive to operate in space. If NASA makes
cheaper robots, they can use the left over money for other projects. NASA
is trying to make all aspects of space flight cheaper so that more can
be done and more people can benefit from it.
[ LisaShore/JSC - 74 - 10:17:23 ]
RE: [AshleyWMS] What is the hardest
thing you have done so far for Nasa?
The hardest thing I've done at NASA so far was to get certified as an
Ascent FDO. It's a really tough training flow. The sim guys, like Mr.
Terry make sure that we see all kinds of failure scenarios that we hope
never happens. It can be extremely stressful at times.
[ TimTerry/JSC - 76 - 10:20:04 ]
RE: [Ellen8_CrestonMiddleSchool] Dear
Mr. Tim Terry, How complicated is it to train crews? What is the average
percentage of people who do not cooperate?
Hello, Ellen8_CrestonMiddleSchool. Fortunately, we put much thought into
the skills and knowledge that an astronaut must possess to fly successfully.
We have developed training plans (much like your teacher develops for
you) that specify the types and duration of training events. The percentage
of students who do not "cooperate" is very small. We're very lucky here
to have students that are extremely interested in learning.
[ LisaShore/JSC - 77 - 10:20:41 ]
RE: [David] Has there ever been a
problem guiding a shuttle back home?
Hi David. We've never had any serious problems guiding the Shuttle back
home. The Entry FDO spends a lot of time planning the deorbit maneuver
burn to make sure that the Shuttle enters the atmosphere at the right
place. After that, the MCC doesn't take control unless something breaks
onboard the Shuttle. That has never happened and we always made the landing
site as planned.
[ RobertDempsey/ISS - 78 - 10:21:04

RE: [NATEandJARED] Do all of you
from Johnson Space Center know each other?
Nate and Jared, Well I know some of the people here (hi Tim!) but this
is a big place so I don't know many of the others.
[ MikeMoses/JSC - 79 - 10:21:23 ]
RE: [NATEandJARED] Do all of you
from Johnson Space Center know each other?
I get to work with Lisa in the MCC a lot. She is an Ascent FDO and I'm
working to become an Ascent PROP. I haven't met Tim face-to-face but have
suffered at the hands of his scripts. He's a SIM SUP, in charge of running
the simulations that train the flight control team.
[ BillFoster/JSC - 83 - 10:22:01 ]
RE: [MrsHestersClass] What is a typical
shift like?
Mrs. Hester's Class - A typical shift begins with a thorough briefing
from the controller you are relieving. Following that briefing, the oncoming
Flight Director polls each position for their latest status. While this
is happening, the outgoing controller continues to work with his/her flight
director on the mission. After the change of shift briefing with the new
flight director is complete, and he/she is comfortable with assuming command,
the outgoing shift is released. What happens next depends on which shift
you are on, what is going on with the flight plans, and what position
you support. As a ground controller, we work constantly with the MCC facility
and with the space tracking and data network people at Goddard and White
Sands. There are really no typical shifts, but all are interesting and
great to be working with the mission and crew.
[ TimTerry/JSC - 84 - 10:22:20 ]
RE: [NATEandJARED] Do all of you
from Johnson Space Center know each other?
I know Bill, Lisa, Bob, and Mike. Bob works with my wife and the other
three have been on the receiving end of training that I and my training
teams provide during simulations.

[ LisaShore/JSC - 86 - 10:22:43 ]
RE: [NATEandJARED] Do all of you
from Johnson Space Center know each other?
I know the rest of the JSC guys. It's a pretty close knit family here
at JSC within Shuttle Operations and we see a lot of each other in sims
and meetings.
[ MikeMoses/JSC - 87 - 10:23:23 ]
RE: [AshleyWMS] If the technology
wasn't as great as it is today, how much harder would it make your jobs?
The technology we use in the MCC is really great. Bill Foster (one of
today's experts) is a GC or Ground Controller. They do a wonderful job
of keeping the MCC running smoothly. The job would be very difficult without
all the technology and support staff.
[ TimTerry/JSC - 88 - 10:24:07 ]

Since Mike mentioned me so nicely, I won't be as tough on him the next
simulation (yeah, right). :)
[ BillFoster/JSC - 91 - 10:25:48 ]
RE: [NATEandJARED] Do all of you
from Johnson Space Center know each other?
Nate and Jared. JSC is a very big facility, and even in the more limited
confines of the flight control community, it is very difficult to know
everyone. Over the course of preparing for a mission, we will sim many
times with the same group of people, giving us a chance to work with them
and get to know them a little better. As a community, however, there is
a tremendous amount of respect and trust among the flight controllers,
so even if you do not know everyone else, there is never a problem working
together.
[ Samantha - 82 - 10:21:32 ]
Lisa as any body died in space in or out
[ LisaShore/JSC - 92 - 10:25:59 ]
Samantha, fortunately nobody has died in space yet. Our number 1 job is
to make sure that doesn't happen. Of course the Challenger crew died on
their way there but hopefully that will never happen again.
[ TimTerry/JSC - 93 - 10:26:14 ]
RE: [AshleyWMS] Can you take pets
in space? Do you use animals for any part of the work at Nasa?
Ashley, I'm sure some astronauts would like to take their pets or family
into space, but it's not possible. Several types of creatures have accompanied
astronauts into space, including rats and bees.
[ RobertDempsey/ISS - 94 - 10:26:51

RE: [JD] Do people that go on tours
of the MCC ever get to meet any of the astronauts or MCC people?
JD, generally no. There are a LOT of people who come through here and
it can be quite distracting to constantly be meeting them.
[ MikeMoses/JSC - 95 - 10:28:49 ]
RE: [Evan] Is their any bugs that
get hit by a spaceshuttle?
The space shuttle has never had a collision in space with anything of
any significant size. What's important to remember is that in orbit everything
is moving extremely fast, so even small things like paint chips can cause
a lot of damage to the shuttle.
[ BillFoster/JSC - 101 - 10:29:29
]
RE: [JD] Do people that go on tours
of the MCC ever get to meet any of the astronauts or MCC people?
JD, The people coming through on the Space Center Houston tours do not
typically get to meet people working in the MCC. They enter through a
visitor's entrance and remain in a viewing room behind glass dividers.
One of the fun parts of working in the White FCR (main shuttle control
room) is watching the tours come through and waving at the visitors when
possible. I have occasionally gone into the viewing room when visitors
are there, but as a rule, there is no interaction. Space Center Houston
does schedule regular sessions where an astronaut is available there for
meeting people and signing autographs. I hope you can come out and visit
us soon. Thanks.
[ LisaShore/JSC - 102 - 10:30:53 ]
RE: [Evan] How fast do space shuttles
travel?
Hi Evan. Once we're in orbit the space shuttle travels at about Mach 25
which is 25 times the speed of sound.
[ RobertDempsey/ISS - 103 - 10:31:04

RE: [Stephen] Which robot "died"first
on the Mars Pathfinder mission
Stephen, on that mission the Sojourner (the mobile robot) died first.
Its battery was only designed for a short life and it actually lived beyond
that.

RE: [LisaShore/JSC] Hi Evan. Once we're in orbit the

That's about 17,500 miles per hour.

RE: [LisaShore/JSC] Hi Evan. Once we're in orbit the
space shuttle travels at about Mach 25 which is 25 times the speed of
sound.
Evan, we generally talk in terms of "feet per second", which for an Orbiter
is about 26,000 feet per second. That's about 17,500 miles per hour.

RE: [Jennnfer/wms] HOW MANY PEOPLE
WORK AT JSC IN THE MISSION CONTROL CENTER?
Jennifer, There are about 50 people involved in supporting the flight
controllers, including about 18 in the front room and the rest in the
support rooms. In addition to these, there are another 20 to 30 controllers
supporting the ground controllers, and another 20 to 30 maintenance technicians
in the building at any one time. Then you have the hardware and software
engineering support people available on call throughout the missions,
including the management support for all areas. Altogether, you may have
over 200 people directly or indirectly involved in support of mission
operations depending on what is happening with the flight. Thanks.

RE: [Samantha] lisa what do you do
in your spare time.
I like to do a variety of things in my spare time. I like sports a lot
and I play golf, softball, Rollerblade, and run. I also play in a billiards
league. When I'm not doing any of that I stay at home and play with my
animals or watch TV or a movie. I have lots of animals (2 dogs, 2 cats,
1 rabbit and 1 turtle) so that takes some time.
[ MikeMoses/JSC - 119 - 10:35:21 ]
RE: [AshleyWMS] How many hours a
day do you work?
When not flying a shuttle mission, we typically work the standard 8 hours
a day. During the mission, a shift is about 9 hours long.
[ TimTerry/JSC - 120 - 10:36:13 ]
RE: [JD] Mr. Terry-What kind of education
does a person have to have in order to be a "student" at NASA? You said
that you had students that are there to learn. How old does someone have
to be to be a student there?
Good question, JD. Our students (flight controllers and astronauts) are
anywhere from their 20s to the 60s in years. Education varies widely,
but most share some type of engineering degree. Aerospace, Mechanical,
Electrical, Chemical, and Computer [engineering] are several types represented
by the JSC workforce. Of course, the Space Shuttle pilots are all military
pilots before they become astronauts at JSC.
[ MikeMoses/JSC - 121 - 10:37:42 ]
RE: [AshleyWMS] How real are the
movies we have seen compared to the actual happenings of in-flight operations
and the space station? (example: Armegedon)
Armageddon was not too realistic. Hollywood was taking a lot of liberties
to make the movie look spectacular.
[ BillFoster/JSC - 124 - 10:39:09
]
RE: [AshleyWMS] How many hours a
day do you work?
Ashley, The number of hours worked a day varies with what is happening.
A typical mission shift will be 9 hours, a typical day in the office is
8 hours (but these generally last 9 to 10 hours, particularly as we get
closer to a flight). Launch and landing sims last 4 to 5 hours of run
time plus 1 to 2 hours of prep time. On orbit sims can last 8 to 9 hours
with an additional hour of debrief time and 1 to 2 hours prep time. Some
of the GCs supporting missions work 12 hour shifts. The fact that this
job is rarely routine is another reason it is fun. Thanks.

RE: [AshleyWMS] How real are the
movies we have seen compared to the actual happenings of in-flight operations
and the space station? (example: Armegedon)
It depends which movie it is. Apollo 13 was very realistic. Movies like
Armageddon take a little more artistic license. The Shuttle can't just
fly around wherever it wants the way it did in that movie. It takes a
lot of planning to rendezvous with a satellite or object and it's usually
a fairly slow process. We can't carry enough propellant onboard to do
all the things they do in the movies but Mike knows that better than any
of us.

RE: [AshleyWMS] How real are the
movies we have seen compared to the actual happenings of in-flight operations
and the space station? (example: Armegedon)
Ashley, Well it depends on the movie. Apollo 13 was very accurate and
gave you a good idea what the life of a flight controller is like. Armageddon
has some accuracies, but they were quickly over shadowed by "creative
license". For example, the Shuttle could not dodge and weave through a
comet cloud like the Millennium Falcon as shown.

RE: [AshleyWMS] How real are the
movies we have seen compared to the actual happenings of in-flight operations
and the space station? (example: Armegedon)
Ashley - Armageddon was a very entertaining movie, but far from realistic
when it comes to space travel. Other movies, such as Apollo 13, come much
closer to reflecting the experiences and talents of astronaut crews and
the experts in Mission Control. As you can imagine, many of us here at
JSC watch these movies and try not to "pick them apart" on their technical
merits. We try to enjoy them.

RE: [NATEandJARED] Mr. Foster Have
you met John Glenn?
Nate and Jared, During all the time that Mr. Glenn was at JSC during preparation
for STS-95, I never did see him, much less meet him. Our schedules just
did not coincide. Following the flight I was invited to the post mission
crew party, and did get a chance to see him there, along with the rest
of the STS-95 crew. Thanks.

RE: [soehlms] Hello, We are just
joining you. Is there anyone here who can discuss how the selection of
payloads are made?
Soehlms, we can probably all help a little - what specific question do
you have? Normally, a team of people will propose an idea to NASA. NASA
will the review it with the aid of experts on whether it can be done,
how expensive, what is the scientific gain and so on. Once selected it
takes many years to actually get the payload to fly.
[ LisaShore/JSC - 136 - 10:43:53 ]
RE: [JD] I've seen funny pictures
where the astronauts faces look funny when they are launching. Why doesn't
this happen after they're in space if they are still going 17,500 miles
per hour? Thank you.
That's a really good question JD. The reason they look funny during a
launch is that they are accelerating to get up to orbital speed. The shuttle
astronauts experience up to three times the force of gravity during a
launch. Once they are in orbit, the engines are turned off and they are
no longer accelerating. Then they are in what we call zero g, which means
if feels like there is no gravity so they just float around.

where the astronauts faces look funny when they are launching. Why doesn't
this happen after they're in space if they are still going 17,500 miles
per hour? Thank you.
JD, the astronauts experience acceleration during liftoff and ascent.
Although these accelerations aren't unusually high, they could cause distortion
of one's face. Once the Shuttle gets to orbit and the main engines shut
down, there is no acceleration (except that toward the Earth, ask your
science teacher) and the astronauts' faces can return to mostly normal.

RE: [davidh/wms] Is it hard to creat
a shuttle?
The Space Shuttle took a very long time to design and build. It has thousands
of systems that have to interact. Each system has redundancy and backup.

RE: [STEPHENGAGNE/MODULEVANIER] Mr
Dempsey,do you know who I could contact for Information on past Nasa robot
missions
Stephen, it depends. For most planetary missions the Jet Propulsion Laboratory
[http://www.jpl.nasa.gov] in Pasadena California is the best
place. They are VERY friendly as I used to write them a lot when I was
your age. For some other missions, Goddard Space Flight Center [http://www.gsfc.nasa.gov] is a good place. Go to the NASA
web page [http://www.nasa.gov] and hunt around for the mission you are
interested in. There is usually a address to contact them if the info
you want is not on the web page.

RE: [JD] How long and when is each
working shift? Is the MCC open 24 hours a day?
JD, The MCC is in operation 24 hours a day, 365 days a year. Since the
launch of the FGB in November of 1998, we have had a limited team of flight
controllers on duty around the clock for space station support. We also
support software development and testing, as well as simulations as needed.
There are times when the building is partially shut down for maintenance
activities, but even then there is a crew of facility management and maintenance
people on duty. Thanks.

RE: [Matthew] Have you ever sent
a camera ship to Pluto?
Matthew, so far NASA has not sent any probes to Pluto. I believe one may
be launched in the next few years, and it will then take many years to
get there but we have not done it yet.

RE: [AshleyWMS] How did you decide
what you wanted to be? (expecially that you wanted to work for Nasa)
I sort of accidentally found out what I wanted to do. After college, I
thought I'd go work for the Air Force doing rocket propulsion testing.
My wife worked for NASA here at the Johnson Space Center, so I moved to
Texas. I ended up getting an interview and started working in mission
control. I was happy to find that I love this job !

RE: [AshleyWMS] How did you decide
what you wanted to be? (expecially that you wanted to work for Nasa)
Ashley, I am lucky. When I was a kid around the time of the first landing
on the Moon it just hit me. I have done many things on my way here but
I knew I wanted to do something with space exploration all my life.

RE: [Jennnfer/wms] CAN WE TAKE ANOTHER
TRIP TO THE MOON AND WE WMS JOIN?
I hope that someday we will take another trip to the Moon. It looks like
we are going to go to Mars first though.

RE: [soehlms] We wanted to know whether
there is an opportunity again for kids and their teachers to propose a
payload idea!
Soehlms, Maybe someone else here knows that for sure. I would guess so
but I would check the NASA web site [http://www.nasa.gov]
under the educational section.
[ MikeMoses/JSC - 150 - 10:53:23 ]
RE: [Chris] Mr. Moses, what controls
do you use to launch the space shuttle and what controls do you use to
help the space shuttle to navigate through space?
Almost all of the controls used to launch the space shuttle are run by
computers and computer programs. The space shuttle itself is also run
by a computer. It uses jets on orbit (the Reaction Control System, RCS)
to control where it points. It uses aero-surfaces during entry, just like
an airplane.
[ MikeMoses/JSC - 156 - 10:56:50 ]
RE: [TERRA] MR.MOSES-HOW BIG IS NASA?
TERRA, I really have no idea how large NASA is. It is spread out all over
the country, with centers in Florida, Texas, Ohio, Maryland, Washington
DC, California, and Mississippi (think I got them all).
[ TimTerry/JSC - 157 - 10:57:23 ]
RE: [JD] Dear Panel-Did you get good
grades in school?
JD, I can't speak for the others, but I got fairly good grades. It's just
as important to choose the correct subjects as it is to perform well.
Stick to your likes and talents and work hard.

RE: [Morty] Mr. Foster, What is the
funniest thing that has happened between you and the Space Shuttle crew
duting communications?
Morty, We do not directly communicate with the crew from the GC console.
Only the Capcom talks to the crew on a regular basis. The surgeon does
during medical conferences, the flight director can if needed, and on
some flights, there is a payload position that can talk to the crew. The
GCs are responsible for making sure the air-to-ground comm system is properly
working, and enabling authorized positions for talk capability (this is
done by our support position called "Comm Tech"). There have been many
humorous exchanges between the crew and Capcom, but none involving the
GCs. Thanks.
[ LisaShore/JSC - 166 - 10:58:58 ]
RE: [JD] Dear Panel-Did you get good
grades in school?
JD, I had good grades in high school. They slipped a little my first couple
of years in college but then came back up again when I started taking
aerospace courses. It was all a matter of being focused. There are a lot
of distractions when you first go away to college. It took me a little
while to get refocused but once I did it was all As and Bs.
[ LisaShore/JSC - 167 - 11:00:18 ]
I have to run off to a meeting everybody. I've enjoyed all your questions
and look forward to chatting with you in the future. bye.
[ MikeMoses/JSC - 168 - 11:00:34 ]
RE: [JD] How long would it take to
get to Mars in terms of weeks, months, years.....?
It really depends on how much propellant you can use to get to Mars. the
typical mission would take 3-6 months of travel time.
[ TimTerry/JSC - 169 - 11:00:45 ]
RE: [MrsBrecheisen/ParsonsMiddleSchool]
When you are loading your astronauts into the space shuttle, do you
ever get to meet the astronauts and get to know then?
MrsBrecheisen/ParsonsMiddleSchool: We don't actually perform the crew
strap in at the Kennedy Space Center. Those in this forum who work in
the Mission Control Center are busily monitor their consoles in preparation
for the launch. Those of us who work in training have (hopefully) done
our jobs and we are on hand to monitor the mission activities. Some instructors
and flight controllers get to know the crew during the course of training
for the flight.

RE: [JD] Dear Panel-Did you get good

RE: [MrsBrecheisen/ParsonsMiddleSchool]
When you are loading your astronauts into the space shuttle, do you
ever get to meet the astronauts and get to know then?
Mrs. Brecheisen, We do not get to meet the astronauts while they are loading
onto the shuttle. We do monitor than over the video feeds and work with
them on comm checks as they get strapped into place. Thanks.

RE: [Ryan] Do you ever get nervous?
Ryan, We train many hours for a flight to be able to handle just about
any contingency, but anyone who does not get nervous when the solids light
off does not understand what is happening. The trick is to not let it
affect your performance. Thanks.

RE: [Sajjad] Is your job dangerous?
Sajjad, The job of a flight controller is not dangerous, other than the
same industrial hazards facing anyone in a computer environment. We have
major safety initiatives underway on a continual basis to prevent even
minor safety hazards. thanks.

RE: [MrsBrecheisen/ParsonsMiddleSchool]
Did you know that you wanted to do this when you were a child?
Mrs. Brecheisen, I have always been infatuated with the space program.
I remember watching the first steps on the moon and the unfolding drama
of Apollo 13. I remember Gene Kranz from those days, and remember the
first time I saw him after coming to work out here. All that said, I started
to college in Journalism, changed to Engineering later, and did not really
think about a job out here until a month or so before I graduated. By
the way - Gene Kranz' book on the Mission Control Center, called Failure
Is Not An Option, is due out next month.

RE: [TERRA] MR.FOSTER-HOW OLD DO
YOU THINK THE SPACE STATION IS?
Terra, It depends on which space station you are referring to. The ISS
is a little over a year old on orbit. MIR has been up since 1986. The
Salyout (I may have this name wrong) was up a few years before that, and
Skylab went up in the early '70s. For MIR and the ISS, these dates are
the first element dates. MIR evolved a lot in the 14 years since it was
launched, and the ISS is still an infant. Thanks.

RE: [JD] Where is the center in Ohio?
JD, the NASA center in Ohio is the Glenn Research Center (formerly called

RE: [Anthony] How do you build a
space shuttle?
Anthony, The space shuttle was built by Rockwell (now part of Boeing)
after several years of design work. It takes hundreds of companies and
thousands of people, including engineers, draftsmen, technicians, welders,
truck drivers, managers, secretaries and just about anything else you
can thing of, to plan, assemble and test a space shuttle. Thanks.
[ BillFoster/JSC - 193 - 11:20:29

RE: [MrsBrecheisen/ParsonsMiddleSchool]
Whats the biggest problem you've had to solve?
Mrs. Brecheisen, About a week prior to the last flight we had a problem
with our command system that resulted in near continuos work for some
of our software people. After determining we could not fix it prior to
flight, we developed procedures to minimize the risk. This may not have
been the most difficult problem in my 20 years out here, but it certainly
spun up a lot of activity in the MCC trying to fix it. It has been fixed
now and will not be a concern for the next flight. Thanks.

RE: [JD] Do you have any more pets,
Mr. Foster? (other than the ones on your profile) (or you did have)

changed. Two poodles and four fish. Thanks.

RE: [Michael] Do you ever miss your
wife?
Michael, In general, my job is similar to any office job. I do not travel
often and am home most evenings. There are times when I spend long hours
at work with brief visits home to rest, or during missions I may have
the midnight shift and sleep when the family is awake. Those times are
a little hard on the family and I do miss my wife and children then. Fortunately,
this does not happen every mission for any individual and I get to be
with my family most of the time, including constantly working with my
9th grade daughter on Algebra II. Thanks.

RE: [JD] I know that the movie, "Rocketman"
is not very realistic. But I was wondering if the part that Jeff Bridges
played has any similarities to your job?
JD, My family really enjoyed the movie "Rocketman". No one in the movie,
however, bore any resemblance to how we do business here, including the
part played by Jeff Bridges. "Rocketman" was intentionally not trying
to portray NASA in a serious light, so it was easy to sit back and ignore
the technical problems with it. "Armageddon", on the other hand, tried
to play it straight, and I did not like the movie (even though I saw some
of it being filmed here). There is a new movie with Clint Eastwood, called
"Space Cowboys" due out in the summer that filmed here last August. I
worked with some of the technical people on it trying to get some of the
technical faults straight, but only time will tell how it will be. Thanks.
