Crew Packing Dragon for Undocking on Thursday

The SpaceX Dragon cargo spacecraft approaches the space station for an automated docking loaded with over 7,000 pounds of science experiments, station hardware, and crew supplies on June 9.
The SpaceX Dragon cargo spacecraft approaches the space station for an automated docking loaded with over 7,000 pounds of experiments, hardware, and crew supplies on June 9, 2023.

A U.S. cargo craft is being packed and readied for its undocking from the International Space Station and its retrieval on Earth at the end of the week. The Expedition 69 crew members also focused their Tuesday research activities on space botany, robotics, and human research.

The SpaceX Dragon cargo spacecraft is nearing the end of its stay at the orbital lab and is scheduled to undock at 12:05 p.m. EDT on Thursday. NASA TV will begin its live undocking and departure coverage at 11:45 a.m. on the agency’s app and website.

NASA Flight Engineers Frank Rubio, Woody Hoburg, and Stephen Bowen along with UAE (United Arab Emirates) Flight Engineer Sultan Alneyadi worked throughout Tuesday continuing to load Dragon with some of the 3,600 pounds of cargo that will return to Earth. Dragon is due to splash down off the coast of Florida about 2:30 a.m. on Friday for retrieval by NASA and SpaceX personnel. Dragon arrived at the station on June 6 packed with over 7,000 pounds of new science experiments, crew supplies, and lab hardware.

The astronaut quartet also split its day with a variety of research and maintenance activities. Hoburg added water to the Advanced Plant Habitat for an upcoming space botany study. Alneyadi swapped components on an artificial gravity-generating research incubator then configured the Astrobee robotic free-flyers for a student competition.

While Rubio spent most of Tuesday on Dragon cargo transfers, he also had time for hardware inspections inside the Microgravity Science Glovebox in the afternoon. Bowen swapped out life support components and charged wearable medical monitoring gear. Bowen and Hoburg also spent an hour before lunchtime reviewing Dragon Endeavour crew spacecraft departure procedures.

Flight Engineer Dmitri Petelin collected his saliva and hair samples for a study that will analyze them to understand how the human immune system adapts to microgravity. Commander Sergey Prokopyev and Flight Engineer Andrey Fedyaev primarily focused their activities on maintenance on Tuesday. The two cosmonauts worked in the Zvezda service module as Prokopyev worked on ventilation systems while Fedyaev checked its power supply and oxygen generator.

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...
