Friday’s Station Research Looks at Skin Cells, Plant Genetics and Exercise
Friday’s Station Research Looks at Skin Cells, Plant Genetics and Exercise
Friday’s research schedule aboard the International Space Station included exploring how microgravity affects skin cells and cotton genetics. The Expedition 66 crew is also learning how to exercise more effectively in weightlessness.
Living in space has been shown to accelerate the rate of skin aging and a new study delivered aboard the Cygnus space freighter seeks to understand why and protect astronaut’s health. NASA astronaut Tom Marshburn started the experiment on Tuesday and has been servicing skin tissue samples that will grow inside the Life Science Glovebox. The samples will be stowed later in a science freezer and analyzed back on Earth to evaluate the cellular and molecular changes that take place in microgravity.
Weightlessness also affects how plants grow and Flight Engineers Kayla Barron of NASA and Matthias Maurer of ESA (European Space Agency) spent Friday morning exploring genetic expression in cotton cultures. The duo worked on cotton cell samples being grown in the Plant Habitat to learn more about the process of plant regeneration possibly improving crop production on Earth.
Exercise is very important in space as the microgravity environment can lead to muscle and bone loss. Two exercise studies on the orbiting lab are investigating different ways to maximize the effectiveness of working out in microgravity. Maurer began his day pedaling on an exercise cycle wearing the EasyMotion body suit that stimulates muscles. The specialized suit may improve and lessen the duration of exercise sessions in space. Roscosmos Flight Engineer Pyotr Dubrov attached sensors to himself and worked out on the Zvezda service module’s treadmill for a Russian exercise study. That investigation looks at how an exercising crew member expends energy and other physiological factors to help keep crews fit and healthy on a long duration spaceflight.
NASA Flight Engineer Raja Chari worked throughout Friday troubleshooting components on the COLBERT treadmill located in the Tranquility module. NASA astronaut Mark Vande Hei performed orbital plumbing duties and took photos for the ongoing SQuARE archaeological project.
At the end of the day, all six flight engineers joined Commander Anton Shkaplerov and practiced an emergency drill. The seven-member crew located station safety gear, translated along escape paths, and coordinated communications with mission controllers for unlikely events such as an ammonia leak, depressurization, or a fire.

This striking image from the NASA/ESA Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298 – which comprises the two galaxies NGC 7469 and IC 5283 – lies roughly 200 million light-years from Earth in the constellation Pegasus.

Station Gears Up for Spacewalks While Conducting Cancer Research
Station Gears Up for Spacewalks While Conducting Cancer Research
Spacewalk preparations and cancer research were among the activities scheduled aboard the International Space Station on Thursday. The Expedition 66 crew also unpacked a U.S. cargo craft and explored using virtual reality while exercising.
NASA astronauts Raja Chari and Kayla Barron began readying the U.S. Quest airlock and collecting tools ahead of a pair of spacewalks planned for mid-March. The duo also reviewed step-by-step spacewalk procedures on a computer using 3D graphics. NASA is continuing to set up the space station’s truss structure for a third set of roll out solar arrays augmenting the orbiting lab’s power system.
Chari earlier partnered with ESA (European Space Agency) Flight Engineer Matthias Maurer investigating how living in space affects visual function. NASA Flight Engineer Thomas Marshburn assisted the duo with the research in the morning before spending the afternoon troubleshooting components on the COLBERT treadmill. Maurer ended his day wearing virtual reality goggles while pedaling on an exercise cycle to learn how to improve the work out experience in space.
A new cancer study started this week after arriving aboard the Cygnus space freighter on Monday. NASA Flight Engineer Mark Vande Hei set up the Life Science Glovebox on Wednesday and began observing tumor cells shipped inside a Cygnus science freezer. On Thursday, Vande Hei continued servicing those samples to better understand the onset and progression of cancer and potentially improve treatments on Earth.
Commander Anton Shkaplerov of Roscosmos was back on plasma physics research Thursday and also transferred cargo from Russia’s ISS Progress 80 cargo craft. Flight Engineer Pyotr Dubrov inspected Russian station modules before exploring ways to maximize space exercise. The duo rounded out the day with eye scans using the Ultrasound 2 device with remote guidance from doctors on the ground.
