I am very hesitant to post some proof since they come with warnings on them. For example, my badge says on the back, "This credential is the property of the United States Government. Counterfeiting, altering or misusing violates Section 499, Title 18 of the U.S Code."
I can post my acceptance letter here:
Edit: Some people noticed that the date on the letter is odd. Since I opened it up on word it updated itself. Here is more proof below.
I would also like to point out that I am one of MANY interns at NASA and this is a welcome to anyone who has interesting projects to share (unless its hush hush then I understand).
So, here is what I do. I work as an intern doing combustion in microgravity experiments. To start, microgravity is simply a state where the force of gravity measure below 10-6, or basically zero gravity. What we basically do is burn a small candle like flame with different fuels and drop them down a huge shaft with a rig to block air drag and record the flame.
This website has a lot more specific projects: http://issresearchproject.grc.nasa.gov/Investigations/ACME/
I am working on the Electric-Field Effects on Laminar Diffusion Flames (E-FIELD Flames). Basically, when a flame burns it produces ions within the reaction that can be manipulated with an electric field that then effects the flame. With this we can improve combustion efficiency and cleanliness. Other projects I know of work with fire safety in space and how a flame reacts in different conditions.
You'll notice that a flame in microgravity resembles a bubble. That is because there is no gravity to induce the buoyancy effect which would cause the hot, burned, gases to rise and allow oxidizer (oxygen in air for most fuels) to recycle itself in the reaction. So the burned gases just bubbles up and expands as fresh oxidizer struggles to push in and continue the reaction.
Let me know if you guys have any other questions about other projects or internship stuff.
EDIT: Going to bed but keep up the great questions and science talk.
