The Expedition 70 crew members kept busy Friday as they look ahead to an off-duty weekend. The International Space Station is back to seven residents after one NASA astronaut and two Roscosmos cosmonauts departed early Wednesday morning. The seven members spent time today preparing spacesuits for upcoming spacewalks and closing out maintenance procedures they began earlier this week.

Commander Andreas Mogensen of ESA (European Space Agency) and Flight Engineer Loral O’Hara of NASA both worked on spacesuit preparations ahead of a round of spacewalks that will take place in October. Working separately, O’Hara recharged spacesuit water tanks while Mogensen scrubbed water from cooling loops inside the suits.

Flight Engineer Jasmin Moghbeli of NASA spent the majority of this week removing and replacing components of the Cold Atom Lab (CAL), which chills clouds of atoms to temps near absolute zero, allowing crew members to study their fundamental behavior, a task that is much more difficult to probe at higher temps. Today, she wrapped up maintenance work on CAL, completing the installation of the science module and re-mating power and data connections.

After lunch, Moghbeli worked with Flight Engineer Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) in the Kibo Laboratory. The duo removed sample carriers on MISSE, which analyzes how exposure to space affects the performance and durability of materials and components such as paints, fabrics, seals, and solar cell technologies. The samples were then stowed for future analysis on Earth. Afterward, Furukawa removed and replaced the filter on the station’s Potable Water Dispenser, a system that provides water for crew consumption and food preparation.

Following yesterday’s off-duty day, the three Roscosmos Flight Engineers were back to orbital tasks today. Konstantin Borisov worked in the Nauka module conducting maintenance, while Nikolai Chub ran the 3D printer in the Zvezda module. He then moved on to work in Nauka with Oleg Kononenko to install and connect cables to a water processing system. Kononenko also spent part of the day preparing for an upcoming experiment that studies transport properties of complex plasmas.

Ahead of the weekend, the space station is orbiting slightly higher after the 85P fired its engines for 6 minutes and 22 seconds Friday morning. The orbital reboost sets up the correct phasing for the ISS Progress 86 resupply mission later this year.

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...
