- Description
In preparation for his second mission to the International Space Station, ESA astronaut Thomas Pesquet is training to be ready for launch. His second six-month mission is called Alpha and will see Thomas launch as part Crew-2 on the SpaceX Dragon spacecraft with NASA astronaut Megan Behnken and Shane Kimbrough and Japanese astronaut Aki Hoshide.
Astronauts need to be ready to do a spacewalk at any time. This video shows Thomas and the crew going through the steps for a spacewalk over multiple days: from the tools, to the suit, from setup to communications and putting the suit on.
Astronauts wear a liquid cooling garment underneath their spacesuit. This is connected to the water system that keeps them cool, or warm, by circulating water around their body. They also don a medical monitor and put a dosimeter in their pocket to measure radiation before entering the hatch.
Thomas describes the process inside the airlock as “like scuba diving in reverse”, as astronauts breathe in a controlled way to rid their blood of nitrogen and adjust to lower pressure.
