Science Full Speed Ahead as Station Preps for Cargo Mission

A muscle study, a robotics test, and space physics hardware were the main research topics aboard the International Space Station on Tuesday. The Expedition 67 crew will also see a Russian cargo craft depart and a new one launch to replace it this week.

Scientists have been exploring how an astronaut’s muscles adapt to weightlessness in order to ensure crews stay healthy in space and can withstand the return to Earth’s gravity. NASA Flight Engineers Kjell Lindgren and Bob Hines paired up today marking their foot, leg, shoulder, and back muscles for the Myotones study. The duo then took turns scanning the marked areas using the Myotones device and the Ultrasound device to measure the muscle’s biochemical properties. Results may improve health monitoring during spaceflight and treatments for muscle conditions on Earth.

Hines then joined NASA Flight Engineer Jessica Watkins for orbital plumbing work in the Tranquility module’s bathroom. The pair also had a robotics test on their schedule today for the Behavioral Core Measures investigation looking at how working on the surface of Mars might affect a crew member’s performance.

ESA (European Space Agency) astronaut Samantha Cristoforetti serviced sample cartridges from inside the Electrostatic Levitation Furnace (ELF) located in the Kibo laboratory module. The ELF can safely measure the thermophysical properties of materials at temperatures of over 2,000 degrees Celsius in microgravity.

Roscosmos Commander Oleg Artemyev and Flight Engineer Denis Matveev trained on a computer today for the automated arrival of the ISS Progress 81 (81P) resupply ship set for 9:03 a.m. EDT on Friday. The 81P is due to blast off three-and-a-half hours earlier from the Baikonur Cosmodrome in Kazakhstan. It will replace the trash-filled ISS Progress 79 cargo craft after it undocks from the rear port of the Zvezda service module early Wednesday morning.

Flight Engineer Sergey Korsakov deactivated Earth observation gear before conducting a physical evaluation on the advanced resistive device that mimics a workout in Earth’s gravity. The first time space-flyer later studied future planetary piloting and robotic control techniques then explored ways to improve communications between international crews and mission controllers from around the world.

End of Week Sees Crew Explore How Space Affects Eyes, Brain and Heart

The Expedition 67 crew continued its ongoing human research today with ultrasound eye exams and blood flow measurements in the brain. The orbital residents also explored robotics and space navigation techniques.

The four astronauts aboard the International Space Station took turns Friday morning scanning each other’s eyes using the Ultrasound 2 device. Flight Engineers Kjell Lindgren, Bob Hines, Samantha Cristoforetti, and Jessica Watkins gathered in the Columbus laboratory module for the eye scans with real time support from personnel on the ground. Results will help doctors understand how living in weightlessness impacts the eye, the retina, and vision.

Earlier, Hines completed a session that required him to wear electrodes and sensors that measured blood flow in his head and chest. The Cerebral Autoregulation investigation is exploring how the human brain regulates its blood flow in microgravity. Results may benefit astronauts who experience lightheadedness and a change in blood pressure after returning to Earth’s gravity.

Watkins turned on an Astrobee robotic free-flyer inside the Kibo laboratory module testing its autonomous maneuvers ahead of the Kibo Robot Programming Challenge 3 for students. Lindgren worked in the cupola setting up a camera to photograph Moon imagery for a study that may help future Artemis astronauts navigate their way to the lunar surface.

Cristoforetti transferred the AstroPi computer from the Harmony module to the Columbus module during the morning. She then spent the afternoon checking out a robotics control system before terminating lithium-ion battery charging operations on pistol grip tools.

Commander Oleg Artemyev joined Flight Engineer Denis Matveev and spent Friday replacing components on the Zvezda service module’s treadmill vibration isolation system. Flight Engineer Sergey Korsakov worked on two different Russian experiments on Friday, one exploring the cardiovascular system’s adaptation to microgravity and the other researching advanced Earth photography techniques.
