According to a story posted today in Space.com, the United States Air Force X-37B unmanned space plane is due to take off Friday to some unnamed location, presumably outside the 100 km boundary to space, on an unspecified mission for some unnamed entity/entities. As a news story, this is rather lacking, but Space.com’s audience is for the most part far more interested in details about the plane and what it can do than in what it actually is doing at the moment. This story does not disappoint in that area, with a picture and decent description of the vehicle’s size, composition and capabilities.
Apparently we’re not supposed to tell anybody about it, but Space.com isn’t cooperating, so neither will I. ;)
