Air Force’s X-37B Spacecraft Sets New Record
AIR FORCE'S MYSTERIOUS X-37B SPACECRAFT SETS NEW RECORD FOR TIME IN SPACE
(CNN) – An Air Force aircraft just finished the longest mission yet for a secretive military test program.
The Air Force says its Air Force X-37B space plane has been in orbit for 718-days.
The military is using the planes to develop reusable space-flight technology.
This is the fifth unmanned plane to be launched into orbit over the past decade.
Each flight has been longer than the one before it.
We do not know why the aircraft is in orbit, how long the Air Force plans to keep it there, or its mission.
The Air Force would only say the space plane will return to earth after its completed all its objectives.
But those objectives remain a closely guarded secret.
