<\/a>NASA astronaut Kate Rubins<\/a> and Japan Aerospace Exploration Agency (JAXA) astronaut\u00a0Soichi Noguchi<\/a> are scheduled to exit the International Space Station<\/a>\u2019s Quest airlock Friday for a spacewalk to complete the installation of solar array modification kits, which were started during the Feb. 28 spacewalk<\/a> in preparation for solar array upgrades<\/a>.<\/p>\n The pair will set their spacesuits to battery power about 7 a.m. EST tomorrow, signifying the start of their spacewalk, which is expected to last about six and a half hours. NASA will begin its live coverage on NASA Television, the NASA app<\/a>, and the agency\u2019s website<\/a> at 5:30 a.m.<\/p>\n Rubins and fellow NASA astronaut Victor Glover<\/a> began work to install modification kits on the farthest set of solar rays on the station\u2019s\u00a0Port-6 truss structure<\/a> during the recent spacewalk. Noguchi will join Rubins in tomorrow\u2019s spacewalk to complete the installation and configuration of the kits in preparation for new solar arrays. The new solar arrays, which will be delivered to the space station on upcoming SpaceX Dragon cargo missions, are a larger version of the Roll-Out Solar Array (ROSA)<\/a> technology and will ultimately increasing the station\u2019s total available power from 160 kilowatts to up to 215 kilowatts.<\/p>\n This will be the 236th spacewalk<\/a> in support of space station assembly. Rubins will be designated extravehicular crew member 1 (EV 1) and wear a spacesuit bearing red stripes. Noguchi will be extravehicular crew member 2 (EV 2), wearing a suit with no stripes.<\/p>\n Rubins arrived<\/a> at the space station Oct. 14, 2020, aboard a Russian Soyuz spacecraft, and Noguchi arrived at the space station in November as part of NASA\u2019s SpaceX Crew-1<\/a> mission. This will be the fourth career spacewalk for each astronaut.<\/p>\n Roscosmos Cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov continued work this week to seal a crack\u00a0<\/a>\u00a0in the service module of the Zvezda compartment aboard the International Space Station.\u00a0This was part of ongoing work to isolate and fix the source of a slight increase above the standard cabin air leak rate aboard the station teams have been investigating over the last year. The crew is in no danger, and the space station has ample consumables aboard to manage and maintain the nominal environment.<\/p>\n To seal the crack, the crew will drill holes in the tips of the cracks to prevent any potential future growth. The cracks will then be sealed right away with two types of sealing paste. Several more layers of paste will be applied with a reinforcement patch, which will be covered with another layer of sealing paste.<\/p>\n After completing the crack repair work, a series of leak checks will be performed.<\/p>\n The metal pieces, instrument data and photos collected will all be sent back to Earth for further analysis.<\/p>\n Learn more about station activities by following @space_station<\/a> and @ISS_Research<\/a> on Twitter as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get The Details…<\/a><\/p>\n Mark Garcia <\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n","protected":false},"excerpt":{"rendered":" NASA astronaut Kate Rubins and Japan Aerospace Exploration Agency (JAXA) astronaut\u00a0Soichi Noguchi are scheduled to exit the International Space Station\u2019s Quest airlock Friday for a spacewalk to complete the installation of solar array modification kits, which were started during the Feb. 28 spacewalk in preparation for solar array upgrades.
