With the flight of Crew Dragon Demo-2 being extended to approximately 65 days, NASA astronauts Doug Hurley and Bob Behnken were trained to carry out any EVAs alongside Cassidy if the need arose.

During any excursions, Cassidy and Behnken would perform the EVAs with Hurley supporting the spacewalk robotically from inside the station.

The two NASA astronauts completed half the work to upgrade the batteries that provide power for one channel on one pair of the station's solar arrays.

The two NASA astronauts completed all the work to replace batteries that provide power for the station’s solar arrays on the starboard truss of the complex.

They then completed tasks to prepare the outside of the Tranquility module for the arrival later this year of the Nanoracks commercial airlock on a SpaceX cargo delivery mission.
