Two astronauts are counting down to a spacewalk planned for next Friday to replace a failed voltage regulator. While those preparations are under way, the crew is also exploring human research, life science and advanced physics.
Next week’s spacewalkers are NASA astronaut Tim Kopra and European Space Agency astronaut Tim Peake. They will replace a voltage regulator to restore power to one of eight power channels and take care of other maintenance tasks. The duo worked on their spacesuit batteries then joined Commander Scott Kelly to review procedures for their Jan. 15 spacewalk.
Cosmonaut Yuri Malenchenko explored magnetic fields and coulomb crystals and transferred cargo from the newest Progress 62 cargo craft. His fellow flight engineers Mikhail Kornienko and Sergey Volkov reported on the station’s scientific achievements for a Russian educational research program.
