Blackstar (spacecraft)

Blackstar is the reported code-name of a secret United States orbital spaceplane system. The possible existence of the Blackstar program was reported in March 2006 by Aviation Week & Space Technology (Aviation Week, AWST) magazine; the magazine reported that the program had been underway since at least the early 1990s, and that the impetus for Blackstar was to allow the United States government to retain orbital reconnaissance capabilities jeopardized following the 1986 Challenger disaster. The article also said that the United States Air Force's Space Command was unaware of Blackstar, suggesting it was operated by an intelligence agency such as the National Reconnaissance Office.

Aviation Week speculated that such a spacecraft could also have offensive military capabilities, a concept colloquially known as "The Space Bomber". The magazine also stated that it was likely that Blackstar would be mothballed, although it is unclear whether this is due to cost or failure of the program.

The Aviation Week report was dismissed a few days later as "almost certainly bogus" and the project termed a "technical absurdity" by Jeffrey F. Bell in an article in Space Daily.
