I interned in the fall for NGST (Northrup Grumman Space Technology) in the communications electronics division. As a 4th year student (in a 5 year program), I got paid 40% more then the average intern from my school. Not only that, but I got to do some real design work an a device that will eventually go into a satellite.
They put me on temporary leave when I left, and told me I could come back at any time with 2 weeks notice.
