Two NASA astronauts are relaxing for the next couple of days as a U.S. space delivery nears its launch to the International Space Station. The Expedition 62 Commander is staying busy with the research and the upkeep of Russian orbital lab systems.

Flight Engineers Jessica Meir and Andrew Morgan are taking it easy Thursday and Friday as they look ahead to the arrival of the Cygnus cargo craft from Northrop Grumman. Cygnus launches Friday at 3:43 p.m. EST and will reach the station less than two days later. Morgan will command the Canadarm2 robotic arm to reach out and grapple Cygnus on Sunday at about 4 a.m. Meir will assist and monitor the space freighter’s approach and rendezvous.

Mission controllers will take over and remotely guide the Cygnus in the grips of Canadarm2 and install it to the Unity module. The two NASA astronauts will open Cygnus’ hatch Sunday afternoon and begin unloading about 7,500 pounds of new science, crew supplies and station hardware. NASA TV will cover all the launch, capture and installation activities live.

Roscosmos Commander Oleg Skripochka started his day jogging on a treadmill for an exercise study. Afterward, the veteran cosmonaut worked on orbital plumbing tasks and housecleaning tasks in the station’s Russian segment.
