Boeing said that a US military space drone landed at the Kennedy Space Center in Florida on Saturday.
The X-37B shuttle has spent more than 10 years in space and flown more than 1.3 billion miles, according to Boeing.
The Space Force's focus on collaboration in space exploration and expanding low-cost access to space for our partners, within and outside of the Department of the Air Force was highlighted by this mission.
The X-37B was designed for the Air Force by the United Launch Alliance.
It has a wingspan of 15 feet and is powered by solar panels.
The Pentagon conducted a number of scientific experiments before the last shuttle launch.
To test how certain materials react in space, to evaluate how ambient radiation affects a series of seeds, and to transform solar radiation into radio-electric energy were all part of the mission.
