Crew Studies How Space Affects Skin Before Station Traffic Increases

Four Expedition 65 astronauts are swapping shifts today for a biology study exploring how long-term microgravity affects skin and the healing process. The other three crewmates are gearing up for next week’s relocation of their Soyuz crew ship to the International Space Station’s newest science module.

Rodents launched to the station aboard the most recent SpaceX Cargo Dragon mission are being observed today inside the Kibo laboratory module. Astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of ESA (European Space Agency) kicked off the Rodent Research-1 Demonstration on Tuesday morning studying the mice inside Kibo’s Life Science Glovebox.

NASA Flight Engineers Megan McArthur and Shane Kimbrough continued the rodent research work in the afternoon. The space biology study seeks to identify genes and observe cell functions that are impacted by weightlessness and affect skin processes. The rodents will be returned to Earth late next week on the Cargo Dragon vehicle for further examination.

The pace of traffic at the orbiting lab picks up next week as three crewmates prepare to move their Soyuz crew ship to a new port. Two days later, a U.S. resupply ship will be next when it departs the station to return to Earth loaded with cargo and science experiments.

Three station crew members will enter their Soyuz MS-18 crew ship next Tuesday and take a short ride to another port. The trio, led by cosmonaut Oleg Novitskiy flanked by NASA Flight Engineer Mark Vande Hei and Roscosmos Flight Engineer Pyotr Dubrov, will first back away from the space-facing Poisk module at 8:21 a.m. EDT. They will do a half-circle around the station and dock less than 45 minutes later to Russia’s Nauka multipurpose laboratory module.

Next Thursday, the SpaceX Cargo Dragon will undock from the Harmony module’s international docking adapter at 9:05 a.m. It will splashdown off the coast of Florida about 14 hours later where SpaceX and NASA personnel will retrieve the vehicle and begin unpacking its precious cargo.

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...
