Crew Has Health Checks, Studies Construction on Planets

Spine scans and eye checks filled a portion of the Expedition 66 crew’s day while also preparing for CubeSat deployments and studying space construction techniques. The astronauts and cosmonauts also worked on U.S. spacesuits and inspected Russian modules aboard the International Space Station.

Medical checkups are a regular occurrence on the orbiting lab as scientists observe how microgravity affects the human body. Data from a variety of in-depth examinations of astronauts’ bodies helps doctors develop methods and treatments to keep crews healthy during long-term space missions.

NASA astronaut Kayla Barron swapped roles as the station’s crew medical officer with ESA (European Space Agency) astronaut Matthias Maurer during Tuesday afternoon. The duo took turns scanning their lumbar spinal section using the Ultrasound 2 device with remote guidance from a doctor on the ground. Barron then wrapped up her day with NASA Flight Engineer Raja Chari for eye imaging tasks once again using the Ultrasound 2 scanner.

Space scientists are also studying how to build structures using resources on other planetary surfaces. One experiment being worked on today by Maurer is looking at how concrete hardens with the lack of gravity. The German astronaut worked in the Harmony module with a variety of cement mixtures observing how pores, bubbles and crystals develop as the samples harden.

NASA Flight Engineer Mark Vande Hei spent his day on life support maintenance tasks. The astronaut, who is nearing 300 continuous days in space, partnered with Chari servicing components that control the thermal environment and the transfer of fluids throughout the space station.

Three-time space station visitor Thomas Marshburn of NASA worked on Tuesday morning readying a small satellite orbital deployer for deployment outside the Kibo laboratory module. The veteran astronaut also worked on U.S. spacesuit gear, including batteries and high-definition cameras, during the afternoon.

In the orbiting lab’s Russian segment, Commander Anton Shkaplerov photographed the interior of the Zvezda service module for inspection by engineers on the ground. Flight Engineer Pyotr Dubrov checked communication hardware then serviced the ventilation system inside the Nauka multipurpose laboratory module.

Week Begins on Station with Science Hardware Work

The seven-member Expedition 66 crew started the last day of January working on a wide variety of research gear supporting biology, physics, and Earth science. Spacewalk tool work and vision tests were also on Monday’s schedule aboard the International Space Station.

NASA astronauts Kayla Barron and Thomas Marshburn kicked off Monday servicing science components, flight hardware and life support gear. Barron started the morning inside the Kibo laboratory module installing a small satellite orbital deployer onto an experiment platform that will soon be placed into the vacuum of space. Marshburn also worked inside Kibo installing ice bricks to condition science freezers. Barron later replaced a robotic hand controller while Marshburn worked on water transfer tasks.

ESA (European Space Agency) Flight Engineer Matthias Maurer once again wore the Metabolic Space medical monitoring device measuring his heart rate and breathing function while riding the station’s exercise bike. The astronaut from Germany also worked on the Mochii electron-scanning microscope then reloaded firmware supporting an array of wireless instrumentation.

NASA Flight Engineer Raja Chari worked on pistol grip tools that spacewalkers use when removing or attaching bolts on the outside of the space station. He also joined Barron and Marshburn participating in vision tests checking for visual acuity using a standard eye chart. NASA astronaut Mark Vande Hei took Monday morning off before spending the afternoon checking cable connections and assisting the cosmonauts with Russian hardware.

Commander Anton Shkaplerov of Roscosmos started the day studying ways to pilot future spacecraft and robots on planetary missions. He then joined Flight Engineer Pyotr Dubrov for a technology study exploring advanced methods to locate landmarks for Earth photography. Dubrov also swapped fuel bottles inside the Combustion Integrated Rack that supports safe research into flames and fuels in microgravity.
