Watch a replay of the landing of Oleg Novitskiy and Thomas Pesquet inside the Soyuz MS-03 crew capsule on the Kazakh stepped Friday, ending their six-and-a-half month expedition on the International Space Station.

Confident in technical and procedural fixes implemented since a launch in August left two Galileo satellites in the wrong orbit, officials with Europe’s navigation program say Friday’s liftoff of two identical craft on a Soyuz rocket will try to fill the same slots in the fleet as targeted by last year’s failed mission.

SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base, California, with 51 small satellites, hosted payloads, and orbital transfer vehicles heading into polar orbit on the Transporter 7 mission. Liftoff occurred at 11:48 p.m. PDT Friday (2:48 a.m. EDT; 0648 UTC Saturday).
