The two ships remained joined for 44 hours, separating once for the Soyuz crew to take its turn to maneuver for docking with the Apollo Command and Service Module.
The Apollo command module from the mission is on display at the California Science Center in Los Angeles. The descent module of Soyuz 19 is on display at the RKK Energiya museum in Korolyov, Moscow Oblast, Russia.
This was the final flight of the Apollo spacecraft.
