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 Cygnus’ automated approach and rendezvous.

Both astronauts including JAXA (Japan Aerospace Exploration Agency) Flight Engineer Satoshi Furukawa relaxed on Friday following the weeklong Cygnus preparations and Ax-3 orientation activities. Station Commander Andreas Mogensen of ESA (European Space Agency) had a light duty day at the end of the week spending a couple of hours aiding the Ax-3 foursome during its science and maintenance-filled itinerary.

Ax-3 Commander and former NASA astronaut Michael López-Alegría joined his crewmates Walter Villadei and Alper Gezeravcı at the start of their shift with blood draws for stowage in a science freezer and later analysis. Afterward, the five-time station visitor partnered with Italian astronaut Villadei configuring hardware that monitors space radiation and how it affects astronauts. At the end of the day, López-Alegría tested a digital voice assistant for its potential to assist with crew operations.

Gezeravcı, Turkey’s first astronaut, tended to algae samples growing in petri dishes for an antibacterial investigation then photographed his Ax-3 crewmates as they worked throughout the day. Mission Specialist Marcus Wandt representing ESA spent Friday juggling a variety of science experiments. The Swedish astronaut powered on plasma physics hardware, collected station air samples for chemical analysis, and taped high frame rate video of thunderstorm conditions in Earth’s stratosphere.

In the Roscosmos segment of the orbiting lab, veteran cosmonaut Oleg Kononenko spent his morning updating laptop computer software before inventorying cargo in the Prichal docking module. First time space flyers Nikolai Chub and Konstantin Borisov split their day studying fluid physics, servicing life support components, and maintaining communications and computer systems.

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

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...
