The intriguingly long mission of the unmanned X-37B has come to a conclusion at last. But the mystery of the mission lingers on.
The US Air Force space plane, one of just two X-37B vehicles in the Pentagon’s inventory, landed Friday morning under the auspices of the 30th Space Wing at Vandenberg Air Force Base in California after 674 days in space — that is, 22 months.
And that’s about all that the space plane’s handlers would say about the mission, aside from the terse statement that it “conducted on-orbit experiments.”
“The mission is our longest to date and we’re pleased with the incremental progress we’ve seen in our testing of the reusable space plane,” the Air Force said in a statement.
