Aging Process, CubeSat Preps, and Space Physics Fill Station Research Schedule

Human research, nanosatellites, and space physics topped the research operations aboard the International Space Station on Wednesday. The Expedition 67 crew also continued packing a U.S. cargo craft while servicing Russian spacesuits.

NASA Flight Engineer Jessica Watkins peered at tissue stem cells through a microscope in the U.S. Destiny laboratory module today to understand how the human immune system ages in space. Observations may provide insights into the biological aging process and tissue regeneration possibly informing new ways to keeps astronauts healthy in space and treat medical conditions on Earth. Watkins then spent the afternoon readying cargo packed inside the SpaceX Dragon resupply ship for return to Earth in mid-August.

A small satellite deployer loaded with CubeSats has been installed on an external science platform and placed inside the Kibo laboratory module’s airlock by NASA astronaut Kjell Lindgren today. The deployer will soon be moved into the vacuum of space where the CubeSats will be released into low-Earth orbit for a variety of research programs. Lindgren later set up an AstroBee robotic free-flyer to rehearse pre-programmed maneuvers for the upcoming student-based Kibo Robotic Programming Challenge 3.

Flight Engineer Samantha Cristoforetti of ESA (European Space Agency) explored the dynamics of foams, droplets, and granular materials with implications for future planetary travel and industries on Earth. She swapped the samples inside the Fluid Science Laboratory’s Soft Matter Dynamics experiment container.

NASA Flight Engineer Bob Hines started his day transferring U.S. spacewalking gear into the orbiting lab’s Russian segment. During the afternoon, he serviced hardware supporting the Ring Sheared Drop fluid physics study that could lead to a better understanding of Alzheimer’s disease and the development of advanced materials.

Roscosmos cosmonauts Oleg Artemyev and Denis Matveev took the U.S. spacewalk components, including tools and video cameras, Hines delivered today and installed them on a pair of Russian Orlan spacesuits. The duo will conduct a spacewalk on Aug. 17 to continue outfitting the European robotic arm. Flight Engineer Sergey Korsakov focused on network cable connections inside the Nauka and Zvezda modules.

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...
