Military spaceplane launched
A prototype spaceplane developed for the US military has been launched into orbit from Florida.
The X-37B, which has been likened to a scaled-down space shuttle, blasted off from Cape Canaveral Air Force Station at 1952 EDT (2352 GMT) on Thursday.
The military vehicle is unpiloted and will carry out the first autonomous re-entry and landing in the history of the US space programme.
The spacecraft can return experiments to Earth for inspection and analysis.
