Astronauts Begin Spacewalk for Solar Array Modifications

NASA astronaut Kate Rubins and Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi have begun their spacewalk outside the International Space Station to complete the installation of modification kits in preparation for upcoming solar array upgrades.

The spacewalkers switched their spacesuits to battery power at 6:37 a.m. EST to begin the spacewalk, which is expected to last about six and a half hours.

Watch the spacewalk on NASA TV, the NASA app, and on the agency’s website.

Rubins is extravehicular crew member 1 (EV 1), wearing a spacesuit bearing red stripes and using helmet camera #22. Noguchi is extravehicular crew member 2 (EV 2), wearing the spacesuit without stripes and helmet camera #20.

Rubins and Noguchi will traverse out the station’s backbone truss structure to the far left (port) side set of solar arrays, the first pair of solar arrays deployed in December 2000. The spacewalkers will work together to complete the installation and configuration of modification kits on solar arrays 4B and 2B, which will enable new solar arrays to be installed to augment the space station’s power supply. Rubins and fellow NASA astronaut Victor Glover began installing the modification kits during the Feb. 28 spacewalk.

Following solar array modification kit configuration, the Rubins will conduct cable routing for the Bartolomeo platform Parking Position Interface (PAPOS) on the Columbus module, Noguchi will replace a Wireless Video System External Transceivers Assembly (WETA), and the pair will perform other get-ahead work as time permits.

This is the 236th spacewalk in support of space station assembly.

  1. How fast is the ISS flying across the sky. My wife and I watched it this morning at 5:43am CST . Awesome view and appreciate all that you folks are doing for Space Technology.

    1. The space station orbits Earth 16 times a day at a speed of approximately 17,500 miles per hour/ 28,500 kilometers per hour. Thanks for going out to #SpotTheStation!
