Wednesday was a busy day for the Expedition 69 crew’s astronauts and cosmonauts as they continued preparing for two different spacewalks at the International Space Station. The first spacewalk will see two astronauts install another roll-out solar array on Thursday. The second spacewalk will take place a week later when two cosmonauts replace hardware and conduct photographic inspections.

Mission managers gave the “go” for Thursday’s spacewalk with NASA astronauts Woody Hoburg and Stephen Bowen. The duo will set their spacesuits to battery power at 8:55 a.m. signifying the official start of their second spacewalk together. The duo will spend about six hours installing a roll-out solar array on the opposite side of the starboard truss segment where they installed the previous roll-out solar array on Friday, June 9. NASA TV begins its live broadcast of the spacewalk at 7:30 a.m. on Thursday on the agency’s app and website.

Hoburg and Bowen started Wednesday readying their spacesuits inside the Quest airlock where they will exit the station into the vacuum of space on Thursday. After lunchtime, the duo organized their spacewalking tools and tethers inside Quest with assistance from NASA Flight Engineer Frank Rubio. Finally, the three NASA astronauts joined Flight Engineer Sultan Alneyadi of UAE (United Arab Emirates) for a final review of the spacewalk procedures and robotics activities necessary to support the solar array installation job.

Two cosmonauts are also getting ready for their own spacewalk scheduled for June 22 for maintenance on the outside of the orbital outpost’s Roscosmos segment. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin spent Wednesday gathering spacewalking hardware, testing support equipment, and configuring their spacesuit components. The duo will exit the Poisk airlock next Thursday and spend about seven hours replacing communications and science hardware and photographing the condition of the Zvezda service module.

Roscosmos Flight Engineer Andrey Fedyaev started his morning working on life support maintenance tasks. Next, he activated and handed over radiation sensors to Hoburg and Bowen who will wear them on their spacesuits during Thursday’s spacewalk. Fedyaev later exercised on a treadmill as ground specialists monitored real-time video of his workout and hardware operations.

Station Wraps Busy Week Before Cygnus Cargo Mission Launches

Image
This high exposure photograph from the International Space Station shows Earth’s atmospheric glow and a starry sky as the orbital complex soared above the Pacific Ocean. The Expedition 70 crew is looking ahead to the arrival of a U.S. cargo craft due to arrive at the International Space Station next week. Meanwhile, the Axiom Space 3 (Ax-3) crew finished its first week in orbit with a busy schedule of research, education, and media activities. Northrop Grumman’s Cygnus cargo craft will take its first ride atop a SpaceX Falcon 9 rocket when it lifts off at 12:29 p.m. EST on Monday from Kennedy Space Center in Florida. The private space freighter will be carrying over 8,200 pounds of science experiments, crew supplies, and lab hardware to the orbiting outpost. NASA Flight Engineer Jasmin Moghbeli is due to capture Cygnus with the Canadarm 2 robotic arm at 3:35 a.m. on Wednesday. She will be on duty that morning along with fellow NASA astronaut Loral O’Hara who will monitor Cygn...

NASA and Sierra Space are making progress on the first flight of the company’s Dream Chaser spacecraft to the International Space Station. The uncrewed cargo spaceplane is planned to launch its demonstration mission in 2024 to the orbital complex as part of NASA’s commercial resupply services. Credit: Sierra Space/Shay Saldana NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024. The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vib...

Crew Dragon Suit Checks as Station Begins Orbital Reboosts

Image
This long-exposure photograph from the space station reveals the Milky Way glittering above a bright but exaggerated atmospheric glow blanketing the Earth’s horizon. The Expedition 63 crew checked out SpaceX Crew Dragon suits today and stayed busy with a full slate of space research. The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October. Flight Engineers Doug Hurley and Bob Behnken inspected the suits they will wear when they return to Earth aboard the Crew Dragon spaceship. The duo tried on their suits for a fit check and ensured the components are in good condition. They are scheduled to depart the station on Saturday and splashdown the following day. NASA TV will cover all the departure activities live. The homebound-duo started the day replacing environmental control system (ECS) hardware aboard the orbiting lab. That work required temporarily removing a plant habitat from the Unity module to...
