ESA astronaut Thomas Pesquet poses as he's spending his first days back on Earth after his Mission Alpha aboard the International Space Station.
Thomas shared this image on his social media channels with the caption: "t’s good to be back. The last 72 hours have been simply incredible, so much action and so much change in so little time. I barely now start realising I’m back from 6 months in space... and I’m starting to process how amazing the journey was."
