The Expedition 61 crew’s schedule was packed today as they researched space biology and packed a pair of spaceships for departure. Wednesday morning also saw the deployment of an experimental satellite outside the International Space Station.
Blood draws and eye checks are part of the crew’s regimen of biomedical activities to help doctors keep astronauts healthy during long-term space missions. Commander Luca Parmitano of ESA (European Space Agency) collected his blood samples this morning before spinning them in a centrifuge and stowing them in a science freezer for later analysis. NASA Flight Engineer Jessica Meir had her eyes scanned in the afternoon by fellow NASA astronaut Andrew Morgan using optical coherence tomography gear.
Meir and Morgan started the day finishing up packing the Cygnus space freighter with trash and discarded gear before it leaves at the end of the week. Cygnus will be detached from the Unity module with the Canadarm2 robotic arm and released into Earth orbit on Friday at 9:35 a.m. EST. NASA TV will cover the release and departure live as mission controllers on the ground remotely command all the robotics work.
Cygnus has another mission to deploy eight CubeSats for communications and atmospheric research once it reaches a safe distance away from the orbiting lab. The space station also saw the deployment early this morning of a Department of Defense CubeSat that is testing space weather and satellite sensor technology. That satellite was deployed outside of the Kibo laboratory module using the specialized Cyclops deployer.
Christina Koch of NASA is returning to Earth next week after 328 days in space on her first mission. She will land in Kazakhstan with Parmitano and cosmonaut Alexander Skvortsov. The trio will board the Soyuz MS-13 crew ship, undock from the Poisk module and parachute to a landing Friday, Feb. 6, at 4:13 a.m. (3:13 p.m. Kazakh time).
Koch will be second only to former astronaut Scott Kelly who lived in space 340 days for the single longest spaceflight by a U.S. astronaut.
