- 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.
The Crew-2 astronauts are training what to do if the International Space Station suffers a major power loss at the NASA Johnson Training Center in Houston, USA. The Station has solar arrays that span the size of a football field and produce up to 90 kilowatts of electricity. A complicated transmission, conversion, distribution and protection network ensures systems run smoothly.
A failure would be a serious situation but oxygen does not deplete very quickly and fresh oxygen can be made chemically without any electricity. There are backups and batteries but a power loss would be a major concern and need to be fixed as soon as possible. The astronauts are using computers to diagnose the problem that run on batteries in this simulation.
