Astronauts Tim Peake and Tim Kopra are getting ready for a spacewalk next week to replace a failed voltage regulator. The duo are scheduled to work outside for 6.5 hours on Jan. 15 for the replacement work and other tasks.
In preparation, Kopra worked on the U.S. spacesuits today that he and Peake will wear next week. Peake, a British astronaut with the European Space Agency, began collecting and configuring their spacewalk tools.
The Expedition 46 crew also continued more advanced space science research onboard the International Space Station. Commander Scott Kelly joined his fellow One-Year crew member Mikhail Kornienko for the Fluid Shifts study. That experiment explores how microgravity increases brain pressure which pushes back on a crew member’s eyes, resulting in changes to their vision.
Cosmonaut Sergey Volkov studied radiation exposure, how international crews relate during missions and worked on maintenance tasks. His fellow cosmonaut and flight engineer Yuri Malenchenko looked at magnetic fields and coulomb crystals and transferred cargo from the newest Progress 62 cargo craft.
