The Expedition 50 crew aboard the International Space Station spent the week working on an array of science, maintenance and spacewalking preparation to close out 2016.
Kimbrough and Flight Engineers Peggy Whitson and Thomas Pesquet are getting ready for a pair of spacewalks on Jan. 6 and 13. The spacewalks, in conjunction with remote robotics work, will complete the replacement of old nickel-hydrogen batteries with new lithium-ion batteries on the station’s truss structure. The crew performed a loop scrub on their spacesuits, reviewed spacewalking procedures and did a fit verification with their suits on Friday.
The crew participated in a variety of science experiments during the week including the Fluid Shifts study, which investigates the causes for lasting physical changes to astronauts’ eyes; performed the final harvest of the Outredgous Romaine Lettuce from the Veggie facility, which is further demonstrating the ability to grow fresh plants in space to supplement crew diets; and continued preparing the station’s Combustion Integrated Rack (CIR) for the upcoming Cool Flames Investigation, which will provide new insight into the phenomenon where some types of fuels initially burn very hot, then appear to go out — but they continue burning at a much lower temperature, with no visible flames (cool flames).
Going into New Year’s weekend, the crew will enjoy their typical off-duty time on Saturday and Sunday. They also will have Monday, Jan. 2 off.
The six-member Expedition 50 crew from France, Russia and the U.S. is heading into the holiday weekend with spacesuit checks and eye studies. The international crew will share a Christmas meal, enjoy a light-duty weekend and take Dec. 26 off.
Commander Shane Kimbrough scrubbed cooling loops and tested the water in a pair of U.S. spacesuits today. Kimbrough and Flight Engineers Peggy Whitson and Thomas Pesquet are getting ready for a pair of spacewalks on Jan. 6 and 13. The spacewalks, in conjunction with remote robotics work, will complete the replacement of old nickel-hydrogen batteries with new lithium-ion batteries on the station’s truss structure.
Whitson, who is spending her second Christmas in space, and Pesquet drew blood, urine and saliva samples for the Fluid Shifts study. That experiment investigates the upward flow of body fluids in space potentially causing lasting vision changes in astronauts.
In the Russian segment of the International Space Station, the three cosmonauts primarily worked on maintenance tasks and science work. Oleg Novitskiy worked on communications gear and experimented with space photography techniques. Sergey Ryzhikov worked on water transfers and a cardiac study. Andrey Borisenko worked on life support equipment before studying how a crew member learns to orient themselves in microgravity.
It’s beginning to look like Christmas on the International Space Station. The stockings are out, the tree is up and the station residents continue advanced space research to benefit life on Earth and in space.
A wide array of research work took place Tuesday with scientists on the ground, working in conjunction with the astronaut lab assistants, exploring different fields.
Behavioral testing was scheduled Tuesday for the Neuromapping study to assess changes in a crew member’s perception, motor control, memory and attention during a six-month space mission. Results will help physicians understand brain structure and function changes in space, how a crew member adapts to returning to Earth and develop effective countermeasures.
Another study is observing why human skin ages at a quicker rate in space than on Earth. The Skin B experiment will provide scientists a model to study the aging of other human organs and help future crew members prepare for long-term missions beyond low-Earth orbit.
