Expedition 71 focused on preparing for a cargo resupply mission with Cygnus, performing spacesuit maintenance, and conducting various scientific tasks. Crew members also practiced for the robotic capture of Cygnus and engaged in regular maintenance and research activities.

Robotic Maneuvers and Arrival Preparations
NASA Flight Engineers Matthew Dominick and Jeanette Epps spent Monday preparing for Cygnus’ arrival reviewing its mission profile and practicing robotic capture maneuvers on a computer. Dominick will command the Canadarm2 to capture Cygnus at 5 a.m. on August 5 while Epps backs him up and monitors the approach and rendezvous activities. Afterward, robotics controllers on the ground will remotely take over Canadarm2 and guide Cygnus toward the Unity module’s Earth-facing port where it will be mated for five-and-a-half months.
Spacesuit Maintenance and Lab Troubleshooting
NASA Flight Engineer Mike Barratt kicked off his day checking on plumbing hardware stowed in the Zarya module before swapping components and configuring a U.S. spacesuit in the Quest airlock. NASA astronaut Tracy C. Dyson spent her morning in the Columbus laboratory module troubleshooting the MARES rack, or Muscle Atrophy Research and Exercise System, then spent the afternoon installing drawer handle brackets on a pair of Human Research Facility racks.

Starliner Crew Checks and Operations
Starliner Commander Butch Wilmore and Pilot Suni Williams entered their spacecraft Monday afternoon and checked its water systems, called down to Boeing mission personnel for a conference, then wore their flight suits momentarily for a pressure test. Wilmore started his morning in the station’s Harmony module assembling the BioServe centrifuge as Williams reviewed procedures for operating the Astrobee free-flying robotic assistants.
Cosmonauts Focus on Space Research and Maintenance
The orbiting lab’s three cosmonauts refocused their activities on Monday to standard space research and lab maintenance duties following a week of inspection tasks in the orbital outpost’s
