NASA astronaut Shane Kimbrough and ESA (European Space Agency) astronaut Thomas Pesquet are scheduled to exit the International Space Station’s Quest airlock Friday for a spacewalk to install and deploy the second of six new solar arrays to help power the orbiting laboratory.

Live coverage of the spacewalk will air on NASA Television, the agency’s website, and the NASA app beginning June 25 at 6:30 a.m. EDT, with the crew members scheduled to set their spacesuits to battery power about 8 a.m., signifying the start of their spacewalk.

During the planned six-and-a-half-hour spacewalk, Kimbrough and Pesquet will work on the far end of the left (port) side of the station’s backbone truss structure (P6) to upgrade the 4B power channel with the installation and deployment of an ISS Roll-Out Solar Array (iROSA).

Two of the new solar arrays arrived at the station in the SpaceX Dragon cargo spacecraft as part of the company’s 22nd commercial resupply services mission to the station. The spacewalk follows two other recent spacewalks. On June 16, Kimbrough and Pesquet moved the first iROSA to a mounting bracket on the 2B power channel on the port 6 truss, where it was secured in its folded configuration. On June 20, the duo returned to the 2B power channel to complete installation and deployment.

The new solar arrays will augment the existing arrays, which are functioning well but have begun to show signs of expected degradation as they have operated beyond their designed 15-year service life. The first pair of solar arrays were deployed in December 2000 and have been powering the station for more than 20 years.

This will be the 241st spacewalk in support of space station assembly. Pesquet will be extravehicular crew member 1 (EV 1), with red stripes on his spacesuit, while Kimbrough will be extravehicular crew member 2 (EV 2), with an unmarked suit. Operating from inside the station, NASA astronaut Megan McArthur, with NASA astronaut Mark Vande Hei serving as backup, will command the robotic arm to maneuver Pesquet and the array as close as possible to the installation location.

The spacewalk will be the ninth for Kimbrough, and the fifth for Pesquet. The pair arrived for a six-month science mission at the space station April 24 with NASA’s SpaceX Crew-2 mission aboard the Crew Dragon Endeavour.

A glacier, pictured from the International Space Station, in the Laguna San Rafael National Park ends at the Rio Nevado in Aysén, Chile. The Expedition 63 crew started the workweek checking out hardware supporting life science, combustion research and ongoing Earth observations. A Russian cargo craft docked to the International Space Station is also being packed with old gear for disposal toward the end of the year. The multitude of microgravity research that takes place every day on the orbiting lab, requires regular maintenance and monitoring by the crew or scientists on the ground. The ongoing research supports innovative applications and insights benefitting Earth and space industries. Today, Commander Chris Cassidy serviced an advanced space microscope and swapped components supporting safe combustion investigations. Cassidy first configured the Light Microscopy Module , part of the Fluids Integrated Rack , which supports basic physics and biology research. Next, the veteran N

Credit: NASA TV At 4:38 a.m. EST, Expedition 64  Flight Engineer Soichi Noguchi of the Japanese Aerospace Exploration Agency used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Flight Engineer Michael Hopkins of NASA monitored Cygnus systems during its approach. Next, ground controllers will command the station’s arm to rotate and install Cygnus, dubbed the S.S.  Katherine Johnson , on the Earth-facing port of the station’s Unity module . NASA Television coverage of installation will begin at 6 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning. Cygnus will remain at the orbiting laboratory for a three-month stay. Watch live on the agency’s website or on the NASA app. Learn more about space station activi

Three spaceships are pictured attached to the space station as the orbital complex flew 261 miles above the Bay of Bengal. Two NASA astronauts are getting their tools and spacesuits ready for Sunday’s spacewalk to ready the International Space Station for new solar arrays. Meanwhile, the rest of the Expedition 64 crew focused on a variety of space research on Thursday. NASA Flight Engineers Kate Rubins and Victor Glover are finalizing their preparations for a planned six-and-a-half hour spacewalk set to begin Sunday at 6 a.m. EST. NASA TV will begin its live spacewalk beginning at 4:30 a.m. Rubins and Glover configured spacewalk tools and checked U.S. spacesuits today before calling down to experts in Mission Control to report on their readiness. The duo today also continued reviewing the spacewalk procedures they will use to upgrade power channels that will soon support new solar arrays. Those solar arrays will be shipped on upcoming Space Dragon cargo missions for installation th
