The super secret military X-37B space plane will soon launch from Kennedy Space Center on a Falcon Heavy rocket, but just when remains… well, a secret. The Space Force’s super secret vehicle first launched back in April 2010. The vehicle, which resembles a mini-space shuttle, has so far spent more than 3,700 days in space… or more than 10 years in orbit. Officials will only say the launch is scheduled for December 10th, but the exact time remains a secret. The boosters will land after the launch at Cape Canaveral Space Force Station, meaning some loud sonic booms will be felt locally.
