Spacewalk Preps Rev Up as Space Science Continues
Spacewalk Preps Rev Up as Space Science Continues
The Expedition 64 crew members are revving up their spacewalk preparations as they juggle an array of advanced space science aboard the International Space Station today.
NASA Flight Engineer Kate Rubins spent Wednesday morning readying a pair of U.S. spacesuits that she and fellow NASA astronaut Victor Glover will wear on Sunday. Rubins was joined by astronauts Michael Hopkins of NASA and Soichi Noguchi of JAXA (Japan Aerospace Exploration Agency) helping with the spacesuit fit checks today which consists of attaching the correctly sized leg, arm, glove and helmet components. All four astronauts called down to Mission Control in the afternoon to review Sunday’s spacewalk procedures.
Glover and Rubins will exit the station on Sunday about 6 a.m. EST to begin readying the station for upcoming solar array upgrades. Rubins will go out again on Friday, March 5, with Noguchi to work on coolant gear and communication systems. NASA TV will broadcast both spacewalks live.
Glover also had time for research work today as he serviced parts inside the Combustion Integrated Rack to support flame and fuel studies safely. NASA Flight Engineer Shannon Walker replaced communications gear inside the Human Research Facility that enables biological and psychological observations of astronauts.
Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov continued inspecting and photographing the hull of the Zvezda service module. Ryzhikov also worked on batteries and cameras before incubating and photographing microbe samples. Kud-Sverchkov checked out Russian life support systems and ventilation gear Wednesday afternoon.

Astronauts Get Ready for Spacewalks After U.S. Cargo Ship Arrives
Astronauts Get Ready for Spacewalks After U.S. Cargo Ship Arrives
Spacewalks are the focus now aboard the International Space Station as the Expedition 64 crew begins unloading four tons of cargo delivered Monday aboard a U.S. space freighter.
NASA astronauts Kate Rubins and Victor Glover are gearing up for a spacewalk on Sunday, Feb. 28, to ready the station for upcoming solar array upgrades. They will set their U.S. spacesuits to battery power at approximately 6 a.m. EST signifying the start of their spacewalk planned to last six-and-a-half hours. NASA TV will begin its live coverage of the spacewalk activities at 4:30 a.m.
NASA managers will discuss that spacewalk, including a March 5 spacewalk with Rubins and JAXA (Japan Aerospace Exploration Agency) astronaut Soichi Noguchi, on Wednesday during a live briefing on NASA TV set for 2 p.m. The second spacewalk will see Rubins and Noguchi work on upgrading coolant gear and communication systems.
The duo spent Tuesday servicing their spacesuits and practicing safety procedures inside the Quest airlock. Glover cleaned the spacesuit cooling water loops and tested the quality of the water samples collected from the loops. Rubins reviewed the spacesuit caution and warning system then checked glove heaters, helmet cameras and batteries.
In the midst of the spacewalk preparations, the orbital residents have begun unpacking the Northrop Grumman Cygnus resupply ship. NASA Flight Engineers Michael Hopkins and Shannon Walker have been offloading the new science hardware, crew supplies and station hardware stowed inside Cygnus. Noguchi transferred Cygnus’ science freezers containing biological samples into the station and installed them into specialized science racks. Rubins and Glover also assisted with the cargo transfers.
Commander Sergey Ryzhikov of Roscosmos started the day sampling the station’s air and surfaces for microbial analysis. He then inspected and photographed the hull of the Zvezda service module. Flight Engineer Sergey Kud-Sverchkov worked on Russian life support systems and station cameras while also assisting the commander with the Zvezda inspection duties.
