The US Air Force’s mystery space plane is back on Earth, following a record-breaking two-year mission.
The X-37B landed at Nasa’s Kennedy Space Centre in Florida early on Sunday.
The US Air Force is keeping quiet about what the plane did in orbit after launching aboard a SpaceX rocket in 2017.
The 780-day mission sets a new endurance record for the reusable test vehicle.
It looks like a space shuttle but is one-fourth the size at 29 feet.

Officials say this latest mission successfully completed its objectives.
Experiments from the Air Force Research Laboratory were aboard.
This was the fifth spaceflight by a vehicle of this sort.
Number six is planned next year with another launch from Cape Canaveral.
According to US Air Force Secretary Barbara Barrett: “Each successive mission advances our nation’s space capabilities.”
