Rubins and Glover tackled the struts for the primary two photo voltaic panels, set to launch in June.
NASA astronauts Kate Rubins and Victor Glover concluded their spacewalk on February 28 at 1:16 PM EST, after seven hours and 4 minutes. Within the third spacewalk of the yr exterior the Worldwide Area Station, the 2 NASA astronauts started work to put in modification kits required for upcoming photo voltaic array upgrades.
They labored on the station’s portside edge to put in a bracket and assist struts on two-mast canisters on the base of the outpost’s present photo voltaic wings there, however have been solely in a position to set up one of many kits whereas assembling a second and storing it for later.
The duo labored close to the farthest set of present photo voltaic arrays on the station’s left (port) aspect, often known as P6. The brand new arrays shall be smaller than the outdated ones as a consequence of advances in photo voltaic expertise. They are going to be put in to roll out in entrance of the six present arrays, permitting the brand new installations to make use of the infrastructure already in place for the present set, in accordance with NASA. Boeing (the prime contractor for house station operations) will present the arrays, with the assistance of its subsidiary Spectrolab and a significant provider, Deployable Area Techniques.
The spacewalkers’ objective was to put in new array assist constructions to the station’s 4B and 2B utilizing a photo voltaic arrays modification package and a number of other instruments, which got here in an enormous bag about 8 toes (2.5 meters) lengthy, and 1 foot (0.3 m) extensive and deep. Rubins and Glover hauled the package and photo voltaic array struts for his or her work in the direction of the suitable fringe of the station, utilizing a particular slingshot machine to make use of crew security tethers removed from the core of the ISS.
This was the third profession spacewalk for each Rubins and Glover. Rubins has now spent a complete of 19 hours and 50 minutes spacewalking.
Area station crew members have carried out 235 spacewalks in assist of the meeting and upkeep of the orbiting laboratory. Spacewalkers have now spent a complete of 61 days, 14 hours, and 11 minutes working exterior the station.
In the course of the spacewalk on March 5, Rubins and Japan Aerospace Exploration Company (JAXA) astronaut Soichi Noguchi will enterprise exterior the orbiting outpost to finish the set up of the 4B array modification package and are anticipated to deal with extra work, together with the venting of ammonia from the Early Ammonia System.
