Working on the project Wiki is the only specific task listed. That's a red-flag in regard to gaining professional Computer science/engineering/programming experience. It's secretarial work [not that there's anything intrinsically wrong with that] not an extension of the CS classroom.
NASA in the headline is also a bit misleading outside the jobs thread, since this is just another contractor [not that there's anything intrinsically wrong with that], but in that industry there are companies that will take interns and give them work that extends the classroom.
I am not saying that this isn't an opportunity for work experience or an entry into the world of government contracting or that there's anything wrong with that industry. But it isn't a job at NASA and working on the Wiki is not the kind of experience that leads to the skill sets NASA seeks for software developers. They need hard computer science ~ they want people who can work with the Peter Norvigs and Margret Hamiltons of the world.
