Gamma ray observatory parts recycled for bomb detection

Nature News: The 9-year mission of NASA’s Compton Gamma Ray Observatory ended in 2000 with a plunge into the Pacific Ocean. But its spare parts are living on — as a detector of dirty bombs.

James Ryan, an astrophysicist at the University of New Hampshire in Durham, has recycled parts from one of the space telescope’s old instruments, realizing that they can work just as well pointing horizontally as they did vertically up into the heavens.
