(NASA) – Two NASA astronauts are scheduled to venture outside the International Space Station Wednesday, Jan. 27, and Monday, Feb. 1, for a pair of spacewalks to finish installing a European science platform and complete long-term battery upgrade work.
The spacewalks will begin about 7 a.m. and will last about six and a half hours.
NASA Flight Engineers Michael Hopkins and Victor Glover, who flew to the space station aboard the SpaceX Crew Dragon Resilience spacecraft, will conduct both spacewalks, which will be the 233rd and 234th in support of space station assembly, maintenance, and upgrades.
The Jan. 27 spacewalk will focus on completing cable and antenna rigging for the “Bartolomeo” science payloads platform outside the ESA (European Space Agency) Columbus module.
The duo also will configure a Ka-band terminal that will enable an independent, high-bandwidth communication link to European ground stations.
After completing the upgrades on the Columbus module, Hopkins and Glover will remove a grapple fixture bracket on the far port (left) truss in preparation for future power system upgrades.
The Feb. 1 spacewalk will address a variety of tasks, including installation of a final lithium-ion battery adapter plate on the port 4 (P4) truss that will wrap up battery replacement work begun in January 2017.
Hopkins and Glover will remove another grapple fixture bracket on the same truss segment, replace an external camera on the starboard truss, install a new high-definition camera on the Destiny laboratory, and replace components for the Japanese robotic arm’s camera system outside the Kibo module.
Hopkins will be extravehicular crew member 1 (EV 1) for both spacewalks, wearing a spacesuit with red stripes, and Glover will be extravehicular crew member 2 (EV 2), wearing a spacesuit with no stripes.
These will be the third and fourth spacewalks in Hopkins’ career and the first and second for Glover.
These two spacewalks are scheduled to be followed by two additional spacewalks in the near future.
During the third spacewalk, Glover and NASA astronaut Kate Rubins will work outside the station to prepare its power system for the installation of new solar arrays to augment the station’s existing power supply.
For the fourth spacewalk, Rubins and Japan Aerospace Exploration Agency (JAXA) astronaut, Soichi Noguchi will continue upgrading station components. Another briefing will be scheduled to preview the next two spacewalks after the dates are set.
