Crewmembers Finish Science Experiments

The Expedition 65 crew capped off this week’s research activities aboard the International Space Station by making headway with various science experiments related to human health and materials performance.

Russian flight controllers continued systems testing Friday on the new Nauka Multipurpose Laboratory Module as it heads toward the International Space Station for a scheduled docking next week.

ESA (European Space Agency) astronaut Thomas Pesquet finished the third part of three GRIP tasks. For the experiment, Pesquet performed a set of movements in the supine position. The GRIP experiment studies the long-duration spaceflight effects on the abilities of human subjects to regulate grip force and upper-limbs trajectories when manipulating objects during different kinds of movements.

Commander Akihiko Hoshide, a Japan Aerospace Exploration Agency astronaut, reconfigured the Cell Biology Experiment Facility – Left (CBEF-L), which is used to conduct space plant research. CBEF-L is an upgraded version of an original facility aboard the space station and provides new capabilities and resources, such as a full high-definition video interface, ethernet, 24 power supply, and a larger-diameter centrifugal test environment.

Hoshide, Pesquet, and NASA Flight Engineers Mark Vande Hei, Shane Kimbrough, and Megan McArthur also took turns undergoing eye exams using a remote ultrasound device. Some astronauts have reported experiencing vision changes during and after spaceflight, and the exams provide insight into how spaceflight affects the eye health of crews throughout the mission.

Kimbrough and McArthur continued conducting runs for the Investigating the Structure of Paramagnetic Aggregates from Colloidal Ellipsoids, or InSPACE-4. For the investigation, the pair took turns distributing particles within the sample vial and activated research equipment. InSpace-4 studies the assembly of tiny structures from colloids using magnetic fields and could shed light on how to harness nanoparticles to fabricate and manufacture new materials.

Additionally, McArthur had a chance to complete a Robotic On-Board Trainer for Research (ROBoT-r) session as part of the Behavioral Core Measures experiment. The purpose of the study is to reliably assess the risk of adverse cognitive or behavioral conditions during extended spaceflight missions. Sessions are completed monthly, starting within two weeks of an astronaut’s arrival on station.

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...
