After becoming commander of the International Space Station, Andreas is now set to go on a spacewalk, or extravehicular activity as it is known to the crew, together with NASA astronaut Loral O’Hara.

To prepare for their spacewalk the spacewalking duo will breathe pure oxygen and do some light exercise to get rid of nitrogen in their blood, which can cause serious health issues when going from a high to a low-pressure environment.

Leak and communication checks will be performed in the Quest airlock before Andreas and Loral exit through the same module to venture outside the International Space Station.
