A mysterious robotic ‘space
plane’ has now been in orbit for a record 677 days – and America is
remaining silent about what it’s doing up there.
The robotic Boeing X-37B craft – also known as Orbital Test Vehicle 4 – conducts long missions in orbit, carrying a classified payload.
Observers have
speculated that the Space Shuttle-esque vehicle might be designed to
destroy satellites – or work as a ‘movable’ satellite itself.
When it landed from a previous
mission, it was greeted by ground crew in biohazard suits – sparking
gossip that there was something radioactive on board.
The aircraft has a wingspan of less than 15ft – and
is taken into space on a rocket, but glides back to Earth like a space
shuttle.
