Space Biology, Human Research Day Before Spacewalk

ISS — Expedition 61 Mission patch.

October 10, 2019

Two astronauts will suit up Friday morning for the second spacewalk in a series of five this month to upgrade International Space Station power systems. In the meantime, the duo and the rest of the Expedition 61 crew are staying on top of ongoing microgravity research today aboard the orbiting lab.

NASA Flight Engineers Andrew Morgan and Christina Koch split their time today between researching space biology and preparing for tomorrow’s spacewalk. Morgan observed and photographed protein crystals in a microscope to support cancer research. Koch explored sequencing the DNA of microbes living on the station.

The duo also worked inside the Quest airlock to ready their spacesuits, tools and tethers before they exit into the vacuum of space Friday at 7:50 a.m. EDT. They will continue swapping out the station’s large nickel-hydrogen batteries with newer, more powerful lithium-ion batteries. NASA TV begins its live coverage at 6:30 a.m.

Commander Luca Parmitano and Flight Engineer Jessica Meir set up an exercise cycle for an aerobic fitness test today. Meir strapped herself on the bike while attached to a variety of sensors for an hour-and-a-half exercise session. Flight surgeons use these evaluations to determine an astronaut’s physiological health before, during and after a flight. She also studied how blood flow to the brain adjusts in microgravity.

Cosmonauts Alexander Skvortsov and Oleg Skripochka continued testing a unique negative pressure suit for its ability to reverse the space-caused upward flow of fluids such as blood in astronaut’s bodies. The veteran station pair also worked on a variety of Russian life support and communications systems.
