Yeah, I worked there for 6 years, mostly at Goddard on the HST project. It was very relaxed - to the point of boredom at times (that's why I left, despite the insanely cool work). The guys in Virginia (where I worked about a year or so, but still on NASA stuff) told a different story about the Orbcomm and other commercial rocket businesses. I have no idea what it's like today though.
