NASA Space Station On-Orbit Status 21 October 2020 – Crew Heads Home Today
(From left) Expedition 63 Commander Chris Cassidy and Flight Engineers Anatoly Ivanishin and Ivan Vagner will return to Earth completing a 196-day research mission aboard the space station.

It is departure day aboard the International Space Station for three Expedition 63 crew members.
The entire six-member space station crew slept in and shifted their schedules to accommodate tonight’s homecoming activities. NASA astronaut Chris Cassidy and Roscosmos Flight Engineers Anatoly Ivanishin and Ivan Vagner will board their Soyuz MS-16 crew ship and undock from the Poisk module at 7:32 p.m. EDT, soar through Earth’s atmosphere and parachute to a landing in Kazakhstan at 10:55 p.m. (Oct. 22, 7:55 a.m. Baikonur time).

All the activities will be broadcast live on NASA TV. Coverage of crew farewells and hatch closing will begin at 3:30 p.m. Undocking coverage will begin at 7 p.m., and Soyuz deorbit burn and landing coverage at 9:30 p.m.

The trio is wrapping up final cargo loading today as they pack station hardware, research samples and personal items inside the Soyuz. After landing, the crew will have logged 196 days in space and circled Earth over 3,100 times for a total of just over 83 million miles.

Sergey Ryzhikov of Roscosmos will assume command of the orbiting lab at the moment the departing crewmates undock tonight. He will be leading Expedition 64 Flight Engineers Kate Rubins and Sergey Kud-Sverchkov during their planned 185-day space research mission.

On-Orbit Status Report

62Soyuz (62S) Undock/Landing: The 62S crew, Chris Cassidy, Anatoly Ivanishin and Ivan Vagner, are preparing to depart the ISS today. 62S undock is scheduled for 6:30 PM CT with landing in Kazakhstan at 9:55 PM CT.


Food Physiology: The crew collected blood, saliva and other samples in support of the Food Physiology investigation. The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status During Adaptation to Spaceflight (Food Physiology) experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.

Standard Measures: The crew collected blood and saliva samples in support of the Standard Measures investigation. The aim of the SM investigation is to ensure consistent capture of an optimized, minimal set of measures from crewmembers until the end of the ISS Program in order to characterize the adaptive responses to and risks of living in space. Among other things, the ground teams perform analyses for metabolic and chemistry panels, immune function, microbiome, etc.


Environmental Health System (EHS) Operations: As part of routine semi-annual maintenance, the crew replaced the sieve cartridges in the AQM and vacuumed the vents for AQM S/N 1010. The crew also retrieved the formaldehyde monitors from their deployed locations and restowed them in the Formaldehyde Monitor Kit (FMK).

Environmental Control and Life Support System (ECLSS) Portable Emergency Provisions (PEP) Inspection: Today, the crew performed the periodic PEP inspection, which involves utilizing a PEPs matrix and inspecting various emergency provisions such as the Portable Fire Extinguisher (PFE), Portable Breathing Apparatus (PBA), Quick Don Mask (QDM), and Extension Hose Tee Assemblies at multiple locations throughout the space station. The crew spends several minutes on each item and notes any visible damage. Inspections are performed routinely to ensure the PEPs are in good operational condition.
