Dragon Crew Ship Changing Ports, Cosmonauts Cleanup After Spacewalk

Four Expedition 69 crew members are reviewing the procedures they will use when they move the SpaceX Crew Dragon spacecraft to a new port on Saturday morning. The rest of the crew aboard the International Space Station is cleaning up after completing a spacewalk earlier this week.

NASA Flight Engineers Stephen Bowen and Woody Hoburg will respectively command and pilot the Crew Dragon Endeavour spacecraft when it undocks from the Harmony module’s space-facing port at 7:10 a.m. EDT on Saturday. The pair will be flanked by UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev during the planned 43-minute relocation maneuver. Endeavour, with the four crewmates inside, will automatically redock to Harmony’s forward port at 7:53 a.m. NASA TV begins it live relocation coverage at 7 a.m. on the agency’s app and website.

The quartet began Friday morning simulating their spacecraft maneuvers in coordination with mission controllers on the ground. Afterward, the foursome held a space-to-ground conference with the controllers discussing training, procedures, and mission readiness.

Endeavour’s relocation will open up Harmony’s top port for the upcoming SpaceX CRS-28 cargo mission. This enables the Canadarm2 robotic arm to reach out and access the cargo inside the SpaceX Dragon resupply ship’s trunk. Inside Dragon’s trunk will be a new set of roll-out solar arrays that the Canadarm2 will grapple and temporarily stow on the station’s starboard-side truss structure. Two astronauts on a future spacewalk will permanently install the roll-out solar arrays on the starboard truss augmenting the orbital outpost’s power generation system.

Three cosmonauts reconfigured the Roscosmos segment of the space station following Wednesday’s spacewalk to move an experiment airlock. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin deactivated and cleaned their spacesuits then stowed the tools they used during their seven-hour, 11-minute spacewalk. Fedyaev, who controlled the European robotic arm (ERA) during the spacewalk, spent Friday inside the Nauka science module removing cameras and powering down the ERA.

Prokopyev and Petelin have one more spacewalk to conduct this month when they exit the Poisk airlock on May 12 to deploy a radiator that was attached to Nauka during a previous spacewalk on April 19. Fedyaev will be inside the station monitoring the spacewalkers who will also fill the radiator with coolant and perform maintenance on the ERA.

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

The five-ton Prichal docking module and its modified, uncrewed Russian Progress delivery spacecraft are safely in orbit headed for the International Space Station following launch at 8:06 a.m. (6:06 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan. Prichal, named for the Russian word for port or berth, has five available docking ports to accommodate multiple Russian spacecraft and provide fuel transfer capability to the Nauka module. Progress will transport Prichal for an automated docking with the space station’s Nauka multipurpose laboratory module Friday, Nov. 26., at 10:26 a.m. Live coverage on NASA TV of rendezvous and docking will begin at 9:30 a.m. To make room for Prichal, the recently relocated, uncrewed Progress 78 cargo craft will undock from Nauka at 6:21 a.m. Thursday, Nov. 25, and follow a path to burn up upon reentry in the Earth
