Fifteen years ago today — April 9, 1994 — the Space Shuttle Endeavour launched from Kennedy Space Center on mission STS-59. Astronauts Sidney M. Gutierrez, Kevin P. Chilton,* Linda M. Godwin, Jerome “Jay” Apt, Michael R. Clifford, and Thomas D. Jones operated the Space Radar Laboratory (SRL-1) on this mission.
You would think, 15 years after it was demonstrated on a shuttle flight, that the U.S. would have a more robust space-based radar capability. Alas, no: when I was on active duty, serving on the Air Staff, the Air Force was still advocating for that program. (Here’s a 2005 Space Review article about it.) I doubt there will be any room for it in the Pentagon budget any time soon.
