Human research was the prime area of study today aboard the International Space Station. Results are helping NASA and its international partners keeps astronauts safe and healthy on long term space missions.

Flight Engineers Michael Hopkins and Victor Glover took turns today exploring how weightlessness impacts their hand-eye coordination. The GRASP study, sponsored by the European Space Agency (ESA), explores how microgravity affects a crew member’s central nervous system. That experiment has been under way at the orbiting lab since 2016, providing researchers critical data and insights on how astronauts adapt to living and working in space.

Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov, the two Expedition 64 cosmonauts, participated in a Russian exercise study today. The duo worked out on a treadmill in the Zvezda service module while attached to a variety of sensors. Observations could lead to improved crew training techniques and more effective work outs on the way to the Moon, Mars, and beyond.

NASA Flight Engineer Kate Rubins readied an external exposure experiment this morning that will be placed outside Japan’s Kibo laboratory module. Afterward, she resumed her work exploring the behavior of water droplets that may lead to more advanced fuel and life support systems.

Japanese astronaut Soichi Noguchi, on his third space mission, set up hardware for a fiber optics study then organized stowage space in the Kibo lab. Flight Engineer Shannon Walker of NASA spent most of Tuesday on maintenance servicing spacesuit batteries and working on stowage tasks in the Tranquility module.

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...
