Wednesday was a light duty day for the five Expedition 65 astronauts, two of whom will go on their third spacewalk this month. The two Russian flight engineers aboard the International Space Station stayed focused on cardiac research and plasma crystal physics throughout the day.
Astronauts Shane Kimbrough and Thomas Pesquet joined NASA Flight Engineers Megan McArthur and Mark Vande Hei for robotics training ahead of Friday’s spacewalk. The quartet reviewed and practiced robotics maneuvers on a computer planned to support the installation of the station’s second roll out solar array.
Kimbrough and Pesquet will begin their third spacewalk in nine days on Friday at 8 a.m. EDT when they set their U.S. spacesuits to battery power. The veteran spacewalkers will spend about six-and-a-half hours on the Port-6 truss structure installing the second roll out solar array on the opposite side of where they installed the first solar array. NASA TV, on the agency’s website and the NASA app, will begin its live coverage at 6:30 a.m.
All four astronauts, including Commander Akihiko Hoshide, spent the morning relaxing following a busy period during the first two solar array installation spacewalks. Hoshide had a full day of rest as the other four astronauts spent the afternoon concentrating on Friday’s spacewalk preparations.
In the orbiting lab’s Russian segment, Roscosmos Flight Engineer Oleg Novitskiy continued trapping clouds of particles using both neon and argon gas for a plasma crystal experiment. He also joined cosmonaut Pyotr Dubrov attaching electrodes to themselves and monitoring their cardiac activity before exercise activities. Dubrov also worked on a navigation study to precisely predict the location of the space station during its orbit.

The Expedition 65 crew continued its space research activities today while two astronauts prepared for their third spacewalk in less than two weeks. The International Space Station will also see a U.S. cargo craft depart and a Russian one launch on the same day next week.
NASA Flight Engineer Mark Vande Hei strapped himself to an exercise cycle and attached sensors to himself on Tuesday morning for a workout study measuring aerobic capacity in space. NASA Flight Engineer Megan McArthur explored how bacteria is affected by microgravity and ways to counteract harmful changes.
Eye checks were back on the schedule for four astronauts on Tuesday afternoon. Commander Akihiko Hoshide and Vande Hei took turns operating medical imaging gear and scanned the eyes of astronauts Shane Kimbrough and Thomas Pesquet. A variety of eye exams take place on the station helping researchers understand how weightlessness impacts an astronaut’s vision.
Kimbrough and Pesquet are also getting ready for more solar array installation work on the outside of the orbiting lab. The duo reviewed procedures today for installing a second roll out solar array on the station’s Port-6 truss structure. The veteran spacewalkers will set their spacesuits to battery power at 8 a.m. EDT on Friday signifying the official start of their third excursion in 9 days. Live coverage on NASA TV starts at 6:30 a.m. on the agency’s website and the NASA app.
Hoshide and Vande Hei spent some time Tuesday morning loading Northrop Grumman’s Cygnus space freighter ahead of its departure scheduled for July 29 at 12:25 p.m. Russia’s ISS Progress 78 resupply ship will launch the same day at 7:27 p.m. and dock to the station two days later at 9:02 p.m.
Roscosmos cosmonaut Oleg Novitskiy packed the ISS Progress 77 resupply ship readying the vehicle for its undocking in late July. The veteran cosmonaut also trapped clouds of particles using both neon and argon gas for a plasma crystal experiment. Russian Flight Engineer Pyotr Dubrov had an exercise test on a treadmill today then serviced a variety of communications and life support hardware.
