Spacewalk preparations continue onboard the International Space Station as the Expedition 68 crew begins it weekend. The orbital residents also worked on space botany and robotics while maintaining orbital lab operations on Friday.

Astronauts Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) worked throughout Friday familiarizing themselves with an upcoming spacewalk. The pair was joined by NASA Flight Engineers Josh Cassada and Frank Rubio for computerized spacewalk training and a conference with specialists on the ground. Two astronauts are scheduled exit the station and mount hardware on the truss structure readying the orbital lab for its next roll-out solar array.

Cassada also continued tending to tomato plants growing for the Veg-05 space botany study and worked on cargo transfers inside the Cygnus space freighter from Northrop Grumman. Rubio inspected emergency hardware than took a computerized robotics test to remain proficient when operating the Canadarm2 robotic arm.

Wakata repaired components on a multipurpose small payload rack in the Kibo laboratory module that supports a wide variety of research and educational activities in space. Mann spent some time tightening screws on the advanced resistive exercise device located in the Tranquility module.

Commander Sergey Prokopyev of Roscosmos worked on a variety of maintenance tasks inside the Zvezda service module on Friday. Flight Engineer Dmitri Petelin transferred cargo from inside the ISS Progress 82 cargo craft and updated the station’s inventory management system. Flight Engineer Anna Kikina set up video equipment to record an exercise session then tested laptop computers inside the Nauka multipurpose laboratory module.

On Thursday, Jan. 12, the International Space Station mission management team polled “go” to move NASA astronaut Frank Rubio’s Soyuz seat liner from the Soyuz MS-22 spacecraft to Dragon Endurance to provide lifeboat capabilities in the event Rubio would need to return to Earth because of an emergency evacuation from the space station. The seat liner move is scheduled to begin Tuesday, Jan. 17, with installation and configuration continuing through most of the day Wednesday, Jan. 18. The change allows for increased crew protection by reducing the heat load inside the MS-22 spacecraft for cosmonauts Prokopyev and Petelin in the event of an emergency return to Earth.

Once the replacement Soyuz MS-23 arrives at the space station on Feb. 22, Rubio’s seat liner will be transferred to the new Soyuz and the seat liners for Prokopyev and Petelin will be moved from MS-22 to MS-23 ahead of their return in the Soyuz.

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...
