Space Biology Research Wraps Up Crew’s Work Week

The sun's first rays begin illuminating Earth's atmosphere as the space station as orbited 260 miles above the central United States.

Bacteria, brain aging, and gravity-sensing cells were the main research subjects aboard the International Space Station on Friday. The seven Expedition 70 crew members also worked on computers, communications gear, and life support maintenance to wrap up the work week.

NASA Flight Engineer Loral O’Hara explored how microorganisms grow in microgravity, the potential damage they cause to spacecraft, and ways to disinfect the harmful bacteria. She inoculated microbe samples inside the Life Science Glovebox that will be compared to uninoculated samples. The NASA-sponsored Bacteria Adhesion and Corrosion study takes place in the Kibo laboratory module and aims to keep space crews and humans on Earth healthy.

Commander Andreas Mogensen from ESA (European Space Agency) viewed cell samples under a microscope for the Cerebral Ageing experiment. The study looks at brain cell-like samples to understand accelerated aging symptoms seen in patients on Earth and observed in astronauts on long-term space missions.

Astronaut Satoshi Furukawa from JAXA (Japan Aerospace Exploration Agency) prepared different cell samples for observation inside the Confocal Microscope then closed out the Cell Gravisensing biology Investigation. Earlier in the day, he swapped hard drives on a laptop computer then assisted O’Hara continuing to unpack the SpaceX Dragon cargo spacecraft.

NASA Flight Engineer Jasmin Moghbeli spent her day in the Harmony module configuring a variety of NASA and Roscosmos hardware. She first calibrated an ultrasonic inspection device that uses high-frequency sound waves to analyze materials, Afterward, Moghbeli checked space-to-ground, VHF, and inter-module communication systems.

Roscosmos cosmonaut Oleg Kononenko researched 3D printing techniques to learn how to manufacture tools and supplies in space and reduce dependence on cargo missions from Earth. Cosmonaut Nikolai Chub spent his day on life support and electronics maintenance. Cosmonaut Konstantin Borisov configured Soyuz crew ship and Progress resupply ship laptop computers then continued his photographic analysis of the station’s Roscosmos 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...
