After circling Earth for an unprecedented 718 days, the X-37B touched down Sunday May 7 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida — the first landing at the SLF since the final space shuttle mission came back to Earth in July 2011
The fourth mission, known as OTV-4, was launched from Florida's Cape Canaveral Air Force Station, and the first three landed at Vandenberg Air Force Base in California. But Air Force officials have said they want to consolidate X-37B launch and touchdown operations on Florida's Space Coast, so Sunday's landing might be the first of many at the SLF (Shuttle Landing Facility).
