I've sadly received a rejection letter from NASA. Strangely, it says there's no space on their training program.
NASA Rejection Letter

Explanation
Experiment
The humor is in the wordplay. The user applied to NASA's training program and got rejected. Instead of a standard rejection, NASA said there is no space, making it sound like there is no physical room rather than no more spots in the program. Space is also the main field that NASA deals with.
