Dragon Returning to Earth Today; Crew Studies Agriculture, Physics

The SpaceX Cargo Dragon resupply ship is pictured departing the station in September of 2021 during the previous SpaceX CRS-23 mission.

A U.S. space freighter is due to return to Earth today after undocking from the International Space Station on Sunday morning. Back on the orbiting lab, the seven-member Expedition 66 crew researched space agriculture and physics.

The SpaceX Cargo Dragon resupply ship is due to end its mission today returning to Earth over 4,900 pounds of science experiments and station hardware for analysis and inspection. Dragon had undocked from the station on Sunday at 10:40 a.m. EST.

Dragon will fire its braking engines Monday afternoon dropping the cargo craft out of orbit and back into Earth’s atmosphere. The U.S. spacecraft will parachute to a splashdown off the coast Florida at 4:05 p.m. EST. NASA TV will not broadcast the cargo craft’s return to Earth and splashdown activities.

Meanwhile, space science continued on the orbital lab as the crew explored a wide variety of microgravity phenomena today. A pair of botany studies kept NASA Flight Engineers Raja Chari and Kayla Barron busy with the duo investigating how to grow crops in space and how microgravity affects cotton genetics. ESA (European Space Agency) astronaut Matthias Maurer installed hardware for the Fluidics experiment to study how to optimize fuel systems for spacecraft.

Maintenance is always ongoing aboard the station ensuring the crew stays healthy and lab systems operate successfully. NASA Flight Engineer Mark Vande Hei started the day tearing down and stowing unused life support gear then photographed payload racks to document their current configurations. NASA Flight Engineer Thomas Marshburn worked throughout the day on U.S. spacesuit batteries and chargers.

Cosmonauts Anton Shkaplerov and Pyotr Dubrov spent the day conducting their complement of science and maintenance in the orbiting lab’s Russian segment. Shkaplerov used a myograph to measure his muscle strength in microgravity before routing air ducts inside the ISS Progress 79 cargo craft. Dubrov had some minor post-spacewalk cleanup work to do prior to swapping fuel bottles inside the Combustion Integrated Rack.

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...
