Last Week on the International Space Station

On Feb. 10, a Cygnus spacecraft carried a fresh supply of 8,300 pounds of scientific investigations and cargo to the orbiting laboratory.

Three NASA astronauts, Mark Vande Hei, Thomas Marshburn, and Kayla Barron, along with ESA (European Space Agency) astronaut Matthias Maurer spent time last week unpacking research samples stowed in science freezers aboard the U.S. Cygnus space freighter. The quartet then loaded the frozen samples into research racks throughout the space station. Some of the new science samples delivered on Monday include skin cells and cancer cells being studied in the microgravity environment to improve human health on Earth and in space.

Two new biology experiments were also delivered by Cygnus. NASA Flight Engineer Thomas Marshburn set up the Microgravity Science Glovebox and began exploring the cellular and molecular alterations taking place in samples of skin cells. NASA Flight Engineer Mark Vande Hei is observing tumor cells in the Life Science Glovebox to better understand the onset and progression of cancer. Both investigations have the potential to inform space research techniques and improve therapies on Earth.

Astronauts Raja Chari of NASA and Matthias Maurer of ESA (European Space Agency) worked throughout Wednesday continuing to offload the 8,300 pounds of cargo delivered Monday inside Cygnus. NASA Flight Engineer Kayla Barron deactivated space botany hardware then photographed cotton cell samples being harvested for the Plant Habitat-05 space agriculture study.

The crew is also revving up for a pair of spacewalks in mid-March to continue modifying the orbiting lab’s power systems. Maurer and NASA Flight Engineer Thomas Marshburn worked on U.S. spacesuit jet packs that an astronaut could use to maneuver to safety in the unlikely event of becoming untethered from the station. Marshburn also reviewed plans to assist spacewalkers from inside the space station including suit up procedures, hardware checks and a communications gear overview.

NASA, SpaceX Provide Update on Crewed Space Station Mission

Crew-3 Launch
A SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched on NASA’s SpaceX Crew-3 mission to the International Space Station with NASA astronauts Raja Chari, Tom Marshburn, Kayla Barron, and ESA (European Space Agency) astronaut Matthias Maurer onboard, Wednesday, Nov. 10, 2021, at NASA’s Kennedy Space Center in Florida. NASA’s SpaceX Crew-3 mission is the third crew rotation mission of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program.

NASA and SpaceX provided an update Feb. 4 on the status of preparations on the agency’s Crew-4 mission to the International Space Station. As part of the news conference, NASA and SpaceX answered media questions on Crew Dragon’s parachutes and work ahead of its next crew launch with NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, as well as with ESA (European Space Agency) astronaut Samantha Cristoforetti.

Listen to a full replay of the news conference, and read the agency’s statement below:

Crew safety remains a top priority for NASA. The agency and SpaceX carefully and methodically monitor the operational parachute performance on all crew and cargo flights to increase safety and reliability.

During the return of the SpaceX CRS-24 mission, teams observed a single main parachute that lagged during inflation like the return of the Crew-2 mission. The vertical descent rate of both flights was within the system design margins at splashdown, and all four main parachutes fully opened prior to splashdown on both missions.

With the commonality between Dragon spacecraft, the mission teams prioritize parachute imagery during return and recovery of the parachutes following splashdown. As partners, NASA and SpaceX jointly review the imagery data and perform physical inspection of the drogue and main parachutes after flight. The inflation model also continues to be updated to better characterize and understand margins and splashdown conditions. This review of flight data and parachute performance models will be completed prior to the launch of the Crew-4 mission and the return of Crew-3 astronauts from the International Space Station.

NASA and SpaceX are completing the parachute analysis as part of the standard postflight reviews conducted at the end of each mission. The results of the data reviews are discussed as part of joint engineering and program control boards and findings presented at the agency’s flight readiness review in advance of the next crew mission. NASA and SpaceX still are targeting launch of the Crew-4 mission Friday, April 15, to the International Space Station.
