ESA astronaut Thomas Pesquet during International Space Station spacewalk maintenance 2 training at the Neutral Buoyancy Laboratory.

Thomas exchanged some of the Space Station heat exchangers that interface the internal cooling loops collecting heat loads, and external ammonia cooling loops that reject heatt via the radiators.

The exchangers are underneath the micro meteorite shields so hard to get to.

Another task involved exchanging ammonia tanks. These tasks are part of 12 major failures that would force an astronaut to go out the door in a short amount of time to repair, and need to be rehears in the NBL pool before flight.

Happy 4th of July USA! Here's a picture of a city in USA, can you find it? Happy searching :)

Un plan de ville quadrillé, des grandes avenues, un CBD... Pas de doute, c'est une vile américaine - mais laquelle ?

What better way to celebrate Canada Day than with this Earth Art in the always beautiful Canada (this is Ontario). Greets to my Canadian Space Agency colleagues, have a great day, hope to see some of you in space soon :)

Une bonne fête nationale aux cousins québecois, aux collègues de l'Agence Spatiale Canadienne et à tout le Canada en général ! Ici une infime portion de ses grands espaces #EarthArt .
