Hey, congrats! I'm hoping to finish mine up this summer (crosses fingers).
And yeah, I do: nothing. ;) This is a test engine, NASA has a bunch of these
Russian-built Hall thrusters (because the Russians are the only ones who
ever produced them in bulk), and they loan them to places like us. Actually,
we're only going to be using the NASA thruster to test out all our
equipment, because we're not allowed to alter it in any way. We'll build our
own thrusters to play around with. My buddy Alex, the grad student who got
me interested in all this stuff, is working on one. They're remarkably
simple things, really.
As of right now the only thing I can think of that's been flown on an ion
engine is NASA's Deep Space One probe, which was flown on an older style
thruster - and is now currently the fastest man-made object in the universe.
;) They have very low thrust (right now), but very high specific impulse
(acceleration/fuel ratio), which means you can run the engine for a LONG
time and continually accellerate. I think the DS1 probe ran its thruster for
~2 years. Fun stuff :) I'm hoping to get a new digital camera soon and get
some pics of the lab. My old one died after I opened it up... go figure.
Good thing it was cheap.

Cool! Coincidentally, I got my private pilot's license today, must be a day
for personal milestones. :)
Any details on what they're gonna fly with that ion thruster? :)
