New human research is underway aboard the International Space Station using the microgravity environment to gain unique insights into aging skin cells and cancer tumors. The Expedition 66 crew also continues to unpack cargo from a U.S. cargo craft while keeping up with eye checks to ensure the crew stays healthy in space.

Weightlessness provides scientists a unique opportunity to observe phenomena not possible in Earth’s gravity. Biology including microbes, plants, and humans, changes in response to microgravity and observations are helping NASA plan longer missions farther into space. Doctors on Earth also use the information to improve numerous treatments and conditions on the ground.

Two new biology experiments delivered on Monday aboard the Cygnus space freighter are already being activated on the orbital lab. NASA Flight Engineer Thomas Marshburn set up the Microgravity Science Glovebox and began exploring the cellular and molecular alterations taking place in samples of skin cells. NASA Flight Engineer Mark Vande Hei is observing tumor cells in the Life Science Glovebox to better understand the onset and progression of cancer. Both investigations have the potential to inform space research techniques and improve therapies on Earth.

Astronauts Raja Chari of NASA and Matthias Maurer of ESA (European Space Agency) worked throughout Wednesday continuing to offload the 8,300 pounds of cargo delivered Monday inside Cygnus. NASA Flight Engineer Kayla Barron Barron deactivated space botany hardware then photographed cotton cell samples being harvested for the Plant Habitat-05 space agriculture study.

Working in the orbiting lab’s Russian segment, Commander Anton Shkaplerov studied plasma physics while Flight Engineer Pyotr Dubrov recorded his heart activity wearing a portable electrocardiogram. The duo from Roscosmos then wrapped up the day with more eye and retina checks using medical imaging gear.

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...
