Hello everybody Mina is here
[ Mina/Ames - 4
- 10:01:42 ]
RE: [Susan/Ames]
Mina what are you working on now?
I am currently working on a wind tunnel test at NASA Langley. Langley
is in Virginia. We have a model of a high speed airplane in the tunnel.
[ scott/bakerhighschool - 6 - 10:02:27 ]
What was your favorite craft to work on? Eric.
[ Mina/Ames - 10
- 10:04:10 ]
Eric, My favorite craft to work on is my car. I like to do my own maintenance.

RE: [kayad/kchs] This is kchs entering the
chat with Mina. Hello. Do you know how to fly?
I do not have my pilot license. I have gone up with friends and they have
let me take over the wheel. I would like to get my license some day.
[ Kris/WaukeshaSchools - 8 - 10:03:53 ]
Hi from Wisconsin!
[ Susan/Ames -
9 - 10:03:53 ]
Hi Kris, welcome! Do you have a question for Mina
[ Mina/Ames - 13
- 10:06:00 ]
RE: [Ivy/MontanaPolytechnicInstitute] How is
the turbulance visualized?
Hi Ivy, As a matter of fact, in the test I am currently on we had to visualize
if the flow was turbulent or laminar. The way we did it is a technique
called sublimation.
[ Mina/Ames - 16
- 10:07:35 ]
RE: [Kris/WaukeshaSchools] What type of metal
is best for reducing drag for flight in airplanes? (Thor)
Hi Kris, All commercial airplanes are made out of aluminum because it
is cheap and it is light. There are some high speed military airplanes
that go so fast that the material has to be made of titanium to withstand
the heat.
[ Susan/Ames -
19 - 10:09:14 ]
Mina is getting some great questions but she can only answer one at a
time so hold on and she'll get to you
[ Mina/Ames - 22
- 10:10:31 ]
RE: [Kris/WaukeshaSchools] Why are the engines
on an F-15 on the inside while commerical planes have the engines on the
outside? (from Angelo)
Kris, It is better if an engine is mounted in the inside of an airplane
to make it mnore streamlined. This cannot be done on a commercial airplane
for safety reasons. If the engine fails on a military airplkane the pilot
can eject. There are some military airplanes that have engines mounted
outside.
[ Mina/Ames - 23
- 10:11:27 ]
RE: [scott/bakerhighschool] What recent breakthroughs
or improvements have been made in your work? Daniel.
Daniel, Computers have been the biggest help in the aeronautics field.
We can take data faster and analyse it quicker.
[ Susan/Ames -
25 - 10:11:56 ]
Welcome Franco
[ Mina/Ames - 26
- 10:13:03 ]
RE: [KJMassey/TheWhiteLakeSchool] How fast
will the new plane fly? I am in second grade.
The new plane will fly a little over twice the speed of sound. It would
be similar to an F-15 in speed.
[ KJMassey/TheWhiteLakeSchool - 28 - 10:13:11
]
Hi, from The White Lake School in Fort Worth, Texas. We are studying space.
Thank you for answering our questions.
[ Mina/Ames - 34
- 10:14:31 ]
RE: [Whipple/GreenMiddleSchool] Is it harder
being a girl aerospace engineer than a male?
It can be harder to be a female aerospace engineer sometimes. It is all
up to you. If you are a strong individual, you will not feel like you
are treated differently.
[ Mina/Ames - 35
- 10:16:00 ]
RE: [Steve/AlamedaElementary] Mina, Where do
you get all the money for the building of the planes?
NASA does not get money to build airplanes unless it is a research plane.
The plane I am working on will probably be built by Boeing. Boeing would
use their own money.
[ Mina/Ames - 38
- 10:17:04 ]
RE: [Steve/AlamedaElementary] Mina, What different
planes have you designed in the past?
I have worked on the V-22 Osprey, a secret military airplane that never
got built, and this high speed civil transport.
[ Mina/Ames - 43
- 10:18:21 ]
RE: [Kris/WaukeshaSchools] If you enjoy your
work now, why are you still interested in becoming an astronaut?
I am the type of person who wants to try new things. Being an astronaut
is a way to get to space. I probably will never be able to become one,
but I want to try.
[ Mina/Ames - 50
- 10:19:54 ]
RE: [Steve/AlamedaElementary] I am a girl in
the 4th grade.I get frustrated and don't know what to do.What do you when
you get frustrated?
When I get frustrated, I sit back and try to re-evaluate the situation.
Try not to respond quickly. You might regret it in the future.
[ Mina/Ames - 51
- 10:20:27 ]
RE: [Steve/AlamedaElementary] Mina, Do you
get to ride in the planes that you design?
I haven't riden on a plane I have designed. I hope to on this one.
[ Mina/Ames - 52
- 10:22:08 ]
RE: [Kris/WaukeshaSchools] What is the fastest
speed that a plane has ever flown?
The fastest airplane is the space shuttle at Mach 25. The next fastest
is the X-15 at Mach 6.
[ Francisco/URBE - 24 - 10:11:56 ]
Hi, Mina. I'm speaking from Maracaibo city, Venezuela in South America.
I want to make two questions: What did NASA do with the few technology
developed during the NASP X-30 proyect ? and What the difference between
the NASP X-30 and the Venture Star X-33 ?
[ Mina/Ames - 58
- 10:24:53 ]
Francisco, The technology NASA developed on NASP, X-30, and X-33 have
all gone into future X projects. All these airplanes would fly to space
instead of the shuttle.
[ Susan/Ames -
59 - 10:26:11 ]
Mina is typing as fast as she can hold your questions for a minute so
she can catch up
[ Mina/Ames - 60
- 10:26:16 ]
RE: [scott/bakerhighschool] What would you
say is the hardest part of your job? Brian.
Brian, The hardest part of my job is having to say no. I always take on
more projects than I can handle.
[ Mina/Ames - 61
- 10:27:41 ]
RE: [Ivy/MontanaPolytechnicInstitute] Is the
word sublimation used in the physics sense, is it a solid turning to a
gas that helps you visualize the air flow?
Ivy, Sublimation is the process of going from a solid to gas. The materials
we use is a mixture of flourene and genesolv. Genesolv is the medium to
spray the flourene on the model.
[ Mina/Ames - 69
- 10:30:23 ]
RE: [Kevin/ButlerHighschool] When I graduate
High School this year, I want to go into Aerospace Eng. How hard is it
to get a job in that field after you graduate
Right now there are jobs in aerospace engineering. But it can be the opposite.
You should study aero eng if that is what you want to do, and not if there
are jobs out there.
[ Mina/Ames - 72
- 10:31:15 ]
RE: [scott/bakerhighschool] What kind of training
did you go through to get to such an important position? Kimberly.
I got a bachelors and masters in mechanical engineering, and I worked
on many projects to gain experience.
[ Mina/Ames - 73
- 10:32:16 ]
RE: [Whipple/GreenMiddleSchool] Hi from Green
Hills School in N.J. How long would it take to travel from NYC to Australia
in the HSCT?
It would probably take 5 to 6 hours to travel from NYC to Australia on
an HSCT. Currently I think it takes 18 hours.
[ Mina/Ames - 74
- 10:33:21 ]
RE: [scott/bakerhighschool] What was the first
engine you worked on? Eric.
The first engine I worked on was for the V-22 Osprey. The V-22 is an airplane
that takes off like a helicopter. Then the wing rotates to fly like an
airplane.
[ Mina/Ames - 78
- 10:34:07 ]
RE: [Steve/AlamedaElementary] Mina, Did you
play with paper airplanes when you were a kid?
Oh, yes!! I always made paper airplanes and got in trouble for hitting
people with them.
[ Mina/Ames - 81
- 10:34:58 ]
RE: [Steve/AlamedaElementary] Mina, did you
ever have a hobby?
I think I have to many hobbies. My favorite hobby is going to hockey games.
Go Boston Bruins!!!
[ Mina/Ames - 82
- 10:35:39 ]
RE: [scott/bakerhighschool] Who or what was
your biggest influence during your training/studies? Sean.
My math teacher.
[ Mina/Ames - 84
- 10:37:05 ]
RE: [KJMassey/TheWhiteLakeSchool] How big are
the engines that you work on, and how much do they weigh? How do you make
the engines? Are they models? First and Sixth graders
The engines are very large. I simulate them in model scale of approximately
6 to 12 inches. The actual engines are built by the engine companies like
GE and Pratt & Whitney. They can be the size of an automobile.
[ Mina/Ames - 85
- 10:38:20 ]
RE: [Gancet/ESIGEC] May we consider the French
"Concorde" as a HSCT ?
Yes, the French Concorde is the preceeding HSCT built in the 60's.
[ Mina/Ames - 86
- 10:38:55 ]
RE: [kayad/kchs] Mina, do you foresee commercial
space travel in the near future?
Yes, I see commercial space travel in the future. Maybe in the year 2020.
[ Mina/Ames - 90
- 10:40:06 ]
RE: [Steve/AlamedaElementary] Mina, How many
days does it take to build an airplane?
Most commercial airplanes can take a year to build from scratch to finish.
If you start at the design phase it can take 5 years.
[ Mina/Ames - 91
- 10:40:51 ]
RE: [Gancet/ESIGEC] What kind of computer is
it used, for the design tests and simulations ?
Some of the computers that are used are Cray Supercomputers and SGI Workstations.
[ Mina/Ames - 96
- 10:41:08 ]
RE: [Steve/AlamedaElementary] Mina, How many
people can ride in your planes?
300 passengers
[ Mina/Ames - 97
- 10:41:33 ]
RE: [Steve/AlamedaElementary] How many of your
planes have crashed?
None that I know of.
[ Mina/Ames - 98
- 10:41:59 ]
RE: [Kris/WaukeshaSchools] Is the F4E Phantom
2 still in existance? (from Mike)
I don't know.
[ Mina/Ames - 104
- 10:43:39 ]
RE: [scott/bakerhighschool] You mentioned in
your bio that your family is from Italy. My family is also from Italy
(2 generations ago). I have found that most of my "millions" of cousins
have entered into the family business. I am one of few that have gone
on to college and received degrees. How does this compare to your family?
Daniel.
I am the first in our family to go to college. I have 3 other cousins
that also went to college. The previous generation never went to college.
They grew up on farms in Italy and did not have the opportunity to go
to high school even.
[ Mina/Ames - 105
- 10:44:40 ]
RE: [KJMassey/TheWhiteLakeSchool] How much
do the new planes cost to build?
Typically airplanes can cost millions to build. A 747 sells for about
5 million.
[ Mina/Ames - 106
- 10:45:18 ]
RE: [Kris/WaukeshaSchools] What materials go
into the jet propulsion system? (from Scott)
Many types of materials are used on a jet engine. From aluminum to composites.
[ Mina/Ames - 108
- 10:46:16 ]
RE: [scott/bakerhighschool] How did you get
your job at NASA? It seems like a lot of people would like to have your
job. Amanda.
I wrote a letter to 3 managers at NASA and sent them my resume. They called
me up for interviews. 3 months later they hired me.
[ Mina/Ames - 109
- 10:47:10 ]
RE: [Whipple/GreenMiddleSchool] What are the
safety concerns you have concerning designing the HSCT?
The three major concerns for the HSCT are noise, making the ozone hole
worse, and sonic boom.
[ Kris/WaukeshaSchools - 112 - 10:47:16 ]
If cost were no object, what materials would you use to build your dream
plane and what features would it include?
[ Mina/Ames - 113
- 10:48:52 ]
My dream plane would be made out of titanium because it is very light
and heat resistant. Some features I would like to have is an automatic
pilot takeoff and landing system. I also would like to be able to watch
TV from this plane.
[ Mina/Ames - 114
- 10:49:40 ]
RE: [Steve/AlamedaElementary] Mina, What is
your favorit cartoon?
My favorite cartoon at the moment is Ren & Stimpy.
[ Mina/Ames - 115
- 10:50:32 ]
RE: [Gancet/ESIGEC] Did you have a good computer
level, before to work for the NASA ?
Yes, it would be a good idea to know how to use computers before coming
to work for NASA.
[ Mina/Ames - 120
- 10:51:53 ]
RE: [Kris/WaukeshaSchools] Is it the materials
or the shape that make a plane undetectable? What do engineers do to accomplish
this?
It is in both the material and shape that make a plane undetectable. Engineers
use alot of computers and testing in acoustic chambers to check out their
designs.
[ Mina/Ames - 121
- 10:52:15 ]
RE: [scott/bakerhighschool] How much does it
cost to test an engine? Britnie.
It can be a million to test an engine.
[ Mina/Ames - 122
- 10:52:54 ]
RE: [Whipple/GreenMiddleSchool] How long will
it be before civilians can fly in the HSCT?
Boeing thinks it might build one for the year 2015.
[ scott/bakerhighschool - 126 - 10:53:38 ]
Mina, thank you very much for your time with us. You are providing a very
important role in the education process. Lots of luck to you in the future
and don't give up on your dream to go into space. Most of us have the
same dream. Mr. Nelson's 7th grade science class.
[ Mina/Ames - 127
- 10:53:40 ]
RE: [Steve/AlamedaElementary] Mina, Is teamwork
important in your job, or do you do more work on your own?
Teamwork is very important. It takes alot of minds and experience to design
an airplane or any other of project.
[ Mina/Ames - 128
- 10:54:34 ]
RE: [Steve/AlamedaElementary] Mina, Do you
like computers?
Most of the times I like computers. There are times when they don't do
what I want, and that is when I get very frustrated and want to throw
it out the window.
[ Susan/Ames -
129 - 10:54:51 ]
RE: [Whipple/GreenMiddleSchool] Will this conversation
be archived like the one was on Tues.?
This chat will be archived. Thanks every one for your great questions.
And Thanks Mina. We earned a lot.
[ Mina/Ames - 130

RE: [Steve/AlamedaElementary] Mina, whats your
favorite food
My favorite food is lamb chops.
[ Mina/Ames - 131
- 10:55:52 ]
RE: [Steve/AlamedaElementary] You said your
math teacher greatly influenced you. How applicable to your job were the
math classes that you took in high school?
The math classes I took in high school are very applicable to what I do
in work. Without them you can't design an airplane.
[ James/ERC - 132 - 10:56:07 ]
Hi Mina, as there seems to be problems in combusting air at high Mach
velocities, have you considered using air merely as reaction mass and
using something like on-board non-imaging optics to heat the air? I gather
that current non-imaging techniques can produce focussing temperatures
of the order of 6000 degrees - enough to pump a CO2 laser system if that
is more efficient than some form of direct solar heating.
[ Mina/Ames - 135
- 10:57:57 ]
RE: [KJMassey/TheWhiteLakeSchool] How much
do you think it would cost for a civilian to fly in the HSCT?
The estimates are that it would cost 20% more than the standard economy
airfare.
[ Gancet/ESIGEC - 136 - 10:58:40 ]
Thanks for all, Mina .
[ Ivy/MontanaPolytechnicInstitute - 137 -
10:58:40 ]
Thank you, Mina, for sharing your time with us!
[ Mina/Ames - 141

RE: [Kevin/ButlerHighschool] What are your
reactions to JPL's Mars missions(MGS and Pathfinder)
I think it is very exciting that we made it to Mars. The picutres that
came back were beautiful.
[ Francisco/URBE - 146 - 11:19:23 ]
nice to meet you, Mina. Long life and prosper...!
[ Norma/n/a - 147 - 11:19:23 ]
