In the past few years a number of small companies have been started to
develop low cost space vehicles, mostly to put small satellites into orbit.
One company has a concept where the vehicle has helicopter blades and
uses them to help it land. There was also a vehicle called the DC-X that
landed vertically like a helicopter.

RE: [Matthias-Matthias/Germany] this question
is not a fake, not for fun!!!
Matthias: Don't worry, it's a good question! Grant is working on an answer
now...
[ Matthias-Matthias/Germany - 23 - 09:10:02

from outside it would look like the fly with "antigravity"
[ GrantPalmer/ARC
- 24 - 09:10:26 ]
RE: [Matthias-Matthias/Germany] since 15 years
i have an idea with me in my head, that can help to build a space-ship-"motor"
for the price of a good car-motor.
The idea these days is to do everything more cheaply. Getting things into
to space is very expensive, so keep thinking.

RE: [IsaiasRamirez-Mrs.Rosales/MilesMagnet]
How do you enjoy time with your family?
I have two sons. They like to go to the zoo, and there is a park by our
house. In a few weeks, my oldest son, who is 4 years old, and I are going
to Las Vegas
[ GrantPalmer/ARC

RE: [Matthias-Matthias/Germany] and please
excuse me for my bad english, i am german with very small contact to enlish-speaking
people. :-(
Your English is a lot better than my German. Don't worry about it.
[ Matthias-Matthias/Germany - 32 - 09:12:37

thank you.
[ GrantPalmer/ARC
- 34 - 09:13:29 ]
RE: [Juan-Mrs.Rosales/MilesMagnet] Do you enjoy
working at NASA what do you like best.
At NASA you get a chance to be creative, to do things that have never
been done before. That is what I like best.
[ GrantPalmer/ARC
- 35 - 09:13:52 ]
RE: [Kevin-Mrs.Rosales/MilesMagnet] How many
languages do you speak.
I speak a very small amount of German and Italian.
[ GrantPalmer/ARC
- 37 - 09:14:46 ]
RE: [DON-Mrs.Rosales/MilesMagnet] What can
you do if you have a degree in mechanical engineering?
Mechanical Engineering is a nice general degree. You study a little bit
of everything, so you can do almost anything with it. I am now a fluid
dynamicist/computer programmer.
[ Sandy/NASAChatHost

Hey, does anyone know what a "fluid dynamacist" is? What do you think
Grnat really does on his job?!
[ GrantPalmer/ARC
- 50 - 09:19:18 ]
RE: [osmin-Mrs.Rosales/MilesMagnet] what is
your favorite sport
I'm a swimmer. My favorite sport to watch is football.
[ Matthias-Matthias/Germany - 51 - 09:20:15

ok, thank you. if it brings "a lot of money", i give you a piece of it
;-))))
[ GrantPalmer/ARC
- 52 - 09:20:49 ]
RE: [Sandy/NASAChatHost] Hey, does anyone know what a "fluid
dynamacist" is? What do you think Grnat really does on his job?!
What a fluid dynamicist does is to figure out how air flows over the outside
of a spacecraft. When a spacecraft, like the space shuttle, re-enters
the atmosphere, the air bouncing off of it causes the surface of it to
heat up. My job is to figure out how hot the surface will get to make
sure it doesn't burn up.
[ Matthias-Matthias/Germany - 53 - 09:21:04
]
oh, the "money-question" is very intersting!
[ GrantPalmer/ARC
- 55 - 09:21:42 ]
RE: [Paola-Mrs.Rosales/MilesMagnet] How much
momey do you make.
Well, you make a pretty good salary at NASA
[ GrantPalmer/ARC
- 58 - 09:22:51 ]
RE: [Matthias-Matthias/Germany] but i think,
it is not allowed to give this information outside ;-)))
Federal Employees, like people who work at NASA, make anywhere from $30,000
to $120,000 depending on how long you've been there and what job you have.
[ GrantPalmer/ARC
- 59 - 09:23:21 ]
RE: [Erik-Mrs.Rosales/MilesMagnet] Where are
you from?
I was born in Southern California. I have lived in the San Francisco Bay
Area for about 30 years.
[ GrantPalmer/ARC

RE: [Jennifer-Mrs.Rosales/MilesMagnet] How
old is your dog?
Bailey is about 7 years old. He's in my office right now.
[ GrantPalmer/ARC
- 63 - 09:25:02 ]
RE: [Alexandra-Mrs.Rosales/MilesMagnet] What
have you learned as you work for Nasa?
The thing about NASA is you have a lot of freedom to do what you want
to do. You can goof off if you want to, but you won't go very far. Since
I came to NASA I have learned a lot about computer programming. Just recently,
I learned how to build my own website.
[ GrantPalmer/ARC
- 65 - 09:25:46 ]
RE: [Ruben-Mrs.Rosales/MilesMagnet] Where is
NASA located?
NASA has centers in California, Texas, Virginia, Alabama, Washington DC,
Maryland, and Cleveland.
[ GrantPalmer/ARC
- 67 - 09:26:22 ]
RE: [Jocelyn-Mrs.Rosales/MilesMagnet] Does
your dog ever bother you?
Sometimes he barks at the mailman when he comes in. I bring Bailey in
about once a week because he gets very lonely at home.
[ GrantPalmer/ARC
- 70 - 09:29:08 ]
RE: [Matthias-Matthias/Germany] if you figure
out the surface of the front of the spacecraft, you do this only with
the computer? last week a have thinked about this and if i has to made
this, i would take a model of the face of the vehicle with a material,
what is not to hard, and bring it into a tube like a wind-channel but
not only with air. i think, i could be helpfull to mix fine sand into
the air and then comes the right surface automatically.
What I do is take a drawing or a computer file that defines the outer
surface of the spacecraft. With my computer, I surround the surface with
little boxes. With my computer program, I can figure out how much air
flows into to each little box and what the temperature and pressure are
in each little box. Basically, I break the surface of the vehicle into
little pieces and calculate the air flow into and out of each piece.
[ GrantPalmer/ARC
- 75 - 09:31:01 ]
RE: [Adriana-Mrs.Rosales/MilesMagnet] What
do you do at your jod?
What I do is to write computer programs and run them. I'll be assigned
a project. Just recently I was asked to compute the flow over an airplane
that is going to be sent to Mars. I had to get the geometry of the airplane
into my computer model. I made some changes to the fluid dynamics code
because the atmosphere of Mars is different than Earth's atmosphere. Then
I ran my program and presented my results.
[ GrantPalmer/ARC
- 77 - 09:31:28 ]
RE: [Robert-Mrs.Rosales/MilesMagnet] What s
your favorite computer?
I like the Cray C-90. It is a really big, fast computer so I can get my
computer jobs done quickly.
[ GrantPalmer/ARC
- 78 - 09:31:53 ]
RE: [jennifer-Mrs.Rosales/MilesMagnet] what
kind of books to you like to read?
I like to read books about ancient cultures like Rome and China.
[ GrantPalmer/ARC
- 79 - 09:32:16 ]
RE: [Susej-Mrs.Rosales/MilesMagnet] Do you
have a computer in your house? How do you use it?
I have a Mac at home. I use it to check my email and work from home.
[ Matthias-Matthias/Germany - 80 - 09:32:21

[ GrantPalmer/ARC
- 82 - 09:33:31 ]
RE: [Matthias-Matthias/Germany] i understand,
thanx. dont work with real models?
There are two types of researchers at NASA, computer people like me and
experimentalist. The experimentalist do test actual models of airplanes
and spacecraft in wind tunnels.
[ GrantPalmer/ARC

[ GrantPalmer/ARC
- 112 - 09:55:17 ]
RE: [Matthias-Matthias/Germany] is it thinkable
to work for the nasa from germany?
You probably couldn't work for NASA directly, but NASA has partnerships
with the European Space Agency, the Japanese Space Agency, and the Russian
Space Agency. Your best bet would be to work with NASA through ESA.
[ GrantPalmer/ARC
