Dragon Checks, Biology and Spacewalk Preps Fill Crew Day

Crew Dragon proficiency checks were on the schedule for a pair of NASA astronauts aboard the International Space Station on Tuesday. Eye checks, space biology research, and spacewalk preparations also kept the Expedition 66 crew busy throughout the day.

The SpaceX Crew Dragon Endeavour, which delivered four astronauts to the orbiting lab, has been docked to the Harmony module’s forward port since Nov. 11, 2021. The Crew Dragon’s commander and pilot, Raja Chari and Thomas Marshburn, both station flight engineers, practiced and familiarized themselves with deorbit and landing procedures in Endeavour today. The duo will return to Earth, along with Kayla Barron of NASA and Matthias Maurer of ESA (European Space Agency), aboard the Crew Dragon in the spring.

Chari and Barron earlier joined each other Tuesday morning for vein scans. Chari took charge as crew medical officer and scanned the veins in Barron’s neck, shoulder and legs with the Ultrasound 2 device. Chari later partnered with Marshburn for eye checks and retina scans using medical imaging gear. Doctors on the ground monitored the vein and eye scans in real time. The regularly scheduled health checks provide researchers insight into how microgravity affects the human body long term.

NASA Flight Engineer Mark Vande Hei documented his meals today to understand how nutrition affects space health. The veteran astronaut, who will be on the station for nearly a year, also serviced a variety of science hardware to ensure ongoing research operations. Maurer continued setting up the Cytoskeleton space biology study that will explore how the human cell’s internal machinery adapts to weightlessness. The ESA astronaut later assisted Chari and Barron with retinal scans then stowing the eye imaging gear.

Cosmonauts Anton Shkaplerov and Pyotr Dubrov are moving right along with their preparations for a spacewalk planned for Jan. 19. The pair from Roscosmos continued collecting and organizing the spacewalk tools they will use to finish configuring and connecting Nauka multipurpose laboratory module to the station’s Russian segment. They are scheduled to work for seven-and-a-half hours outside in the vacuum of space inside their Russian Orlan spacesuits.
