The Expedition 67 crew is gearing up for the departure of the first private astronaut mission and another spacewalk at the International Space Station. There was still time onboard the orbiting lab on Friday for biomedical science to understand how the human body adapts to microgravity.

NASA’s station Commander Tom Marshburn spent some time on Friday assisting the four outgoing Axiom Mission 1 (Ax-1) crew members. The first private space quartet is getting ready to end a two-week stay at the station this weekend. Ax-1 Commander Michael Lopez-Alegria will board the SpaceX Dragon Endeavour with Pilot Larry Connor and Mission Specialists Mark Pathy and Eytan Stibbe and close the hatch at 4:30 p.m. EDT on Saturday. The four Ax-1 astronauts will then undock at 6:35 p.m. from the Harmony module’s space-facing port for splashdown on Sunday off the coast of Florida.

The next mission event planned at the station is the fifth spacewalk of the year for more maintenance and upgrades at the station. Roscosmos cosmonauts Oleg Artemyev and Denis Matveev will partner up once again on April 28 to continue activating the European robotic arm (ERA) attached to the Nauka multipurpose laboratory module.

The duo joined their fellow cosmonaut Sergey Korsakov on Friday morning and reviewed the tasks planned for the upcoming spacewalk. That excursion will see the ERA’s first motion setting up the manipulator for future robotic activities on the station’s Russian segment. The trio then spent the rest of Friday on a variety of inspection and maintenance tasks.

Flight Engineers Kayla Barron of NASA and Flight Engineer Matthias Maurer of ESA (European Space Agency) processed blood and urine samples during the morning for later analysis. NASA Flight Engineer Raja Chari worked on life support gear then joined Marshburn for pre-departure activities inside the Dragon Endurance crew ship.

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...
