NASA TV is Live as Astronauts Prep for Spacewalk to Continue Power System UpgradesNASA Television coverage of today’s spacewalk with NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata is now underway and is also available on the NASA app and the agency’s website.The two Expedition 68 crew members are preparing to exit the International Space Station‘s Quest airlock for a spacewalk expected to begin at about 8:15 a.m. EST and last up to seven hours.Mann and Wakata will work to complete the construction of a mounting platform on the 1A power channel as part of a planned solar array augmentation on the starboard side of the station’s truss.The duo will complete the installation of the mounting platform that was started during a spacewalk on Jan. 20, relocate and install an articulating portable foot restraint from the P6 truss for future spacewalk tasks, and if time permits, complete cable routing on the 1B power channel.The installation is part of a series of spacewalks to augment the station’s power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four iROSAs have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks following their arrival later this year on SpaceX’s 28th commercial resupply services mission for NASA.Mann will serve as extravehicular crew member 1 and will wear a suit with red stripes. Wakata will serve as extravehicular crew member 2 and will wear an unmarked suit. The spacewalk will be the second for both Mann and Wakata.
Expedition 68 Flight Engineers (middle left to right) Josh Cassada and Frank Rubio, both from NASA, pose with astronauts (far left and right) Nicole Mann from NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) in their Extravehicular Mobility Units (EMUs), or spacesuits, as they prep for a spacewalk on Jan. 20, 2022.
The first task of the day is complete as the lower strut of the solar array modification kit is now fully installed. Mann and Wakata are slightly ahead of schedule about an hour into the spacewalk.📺 Watch live on @NASA TV: nasa.gov/live
Nearly three hours into the spacewalk, Mann and Wakata are working together to drive the collar bolts that will rigidize the mounting structure, preparing it to hold the roll-out solar array that will be installed later this year. 🔩🔧
About five hours into today's spacewalk, astronauts @AstroDuke and @Astro_Wakata continue installing hardware to prepare the space station for its next roll-out solar array. nasa.gov/live
US EVA-85: As of today, 4 of 6 IROSA blankets have been installed and an additional two IROSA mounting brackets have been completed; the final 2 IROSAs are expected to launch in June aboard the CRS-28 cargo flight; they'll be mounted and unfurled in a subsequent EVA
Astronauts @AstroDuke and @Astro_Wakata completed their spacewalk today at 2:26pm ET after installing hardware readying the station for its next roll-out solar array.
Today, spacewalkers @AstroDuke & @Astro_Wakata finished installing a support structure that will house a solar array. As construction proved a little tricky at first, Mission Control brought out a model to help walk them through the installation.
The astronaut work trip so far is 10/10 for scenery and 0/10 for gravity.Tune in as @AstroDuke and @Astro_Wakata make updates to the @Space_Station.
Another successful @Space_Station spacewalk completed today! Great work by Flight Engineers Nicole Mann and Koichi Wakata. And a special thank you to allour flight control teams supporting the mission from the ground @NASA_Johnson.
Today's spacewalk has been completed. Nicole Mann and Koichi Wakata were able to complete the support truss for the final set of iROSAs slated for delivery to the Station aboard SpaceX CRS-28 this summer.Article by Justin Davenport (@Bubbinski):
At the end of their spacewalk, which lasted 6 hours and 41 minutes, @Astro_Wakata takes a photo of @AstroDuke.The astronauts prepared the @Space_Station for new solar arrays that will provide the orbiting laboratory with more power.
We would like to express our gratitude to the many people who have supported us in carrying out spacewalks. We faced many challenges during the on-orbit work, but we were able to overcome them and complete the work safely thanks to the teamwork of the crew and the ground control team. The ISS appeared to shine brightly in the pitch-black space.
