(CNN) -- The space shuttle Atlantis will be in space for one more day than originally planned, NASA announced Monday.
The shuttle, which was scheduled to land July 20, will now make what NASA called a night landing at Kennedy Space Center at 5:56 a.m. July 21.
Atlantis lifted off Friday on NASA's final space shuttle mission.
On board is a four-person team: mission commander Christopher Ferguson, pilot Doug Hurley and mission specialists Sandy Magnus and Rex Walheim. The crew of veteran astronauts docked Sunday at the International Space Station to deliver a load of supplies.
