Eye scans and station maintenance continue for the Expedition 69 crew aboard the International Space Station today.

NASA astronaut Woody Hoburg started his day observing and taking photos of satellites that were recently deployed from a Small Satellite Orbital Deployer in the Japanese Experiment Module. He then moved into the station’s Tranquility module to troubleshoot and inspect the Air Revitalization System rack, which removes Carbon Dioxide from the air and monitors the cabin atmosphere.

Near the end of the day, Hoburg joined United Arab Emirates (UAE) Flight Engineer Sultan Alneyadi for an eye ultrasound exam following Alneyadi’s earlier set up of the equipment. Frequent exams of the sort are necessary for the crew to mitigate any noticeable effects or changes to the eyes.

NASA astronaut Stephen Bowen began his morning collecting saliva samples for ongoing research. In the afternoon, he performed six-month maintenance on the Advanced Resistive Exercise Device (ARED) and ended his day with an eye ultrasound scan as well.

NASA Flight Engineer Frank Rubio stayed busy with an abundance of tasks throughout the day. Rubio inspected tools and hardware used during Extravehicular Activities (EVAs) to ensure they’re ready for future use. Afterward, he set up the drain and replaced the exhaust filter in the station’s wastewater processor system. To wrap up his day, Rubio separated Hicari-2 samples from their cartridges in preparation for their return and future inspection. Hicari, an experiment led by the Japanese Aerospace Exploration Agency (JAXA), investigates high-quality crystal growth of semiconductors.

Flight Engineers Dmitri Petelin and Andrey Fedyaev of Roscosmos joined their crew members for end-of-day eye scans. Petelin also resumed his experimental work that studies behavior of liquid diffusion in microgravity, while cosmonaut Commander Sergey Prokopyev worked on inventory and cargo plans for the upcoming ISS Progress 85 mission.

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...
