![Software Worries Delay Pegasus Launch of NuSTAR]()
NASA has postponed the launch of its Nuclear Spectroscopic Telescope Array (NuSTAR) mission for an unspecified number of weeks because of suspected problems with its Pegasus launch vehicle’s flight software, the agency said March 16.
I recently read your editorial “Don’t Shortchange ALASA” [Nov. 21, page 18], with which I generally agree. However, I was dismayed by your description of our Pegasus program as the “one qualified success” of the U.S. Defense Advanced Research Projects Agency (DARPA) in space launch vehicles and by the inattention to the historical facts of its development and operations. Contrary to your interpretation, the Pegasus program, as measured against virtually any common space industry benchmark, has been an “unqualified” success for more than two decades.
