ESA astronaut Thomas Pesquet in the Japanes HTV-6 cargo ferry during his six-month Proxima mission on the International Space Station on 13 December 2016.
Thomas wrote this caption for the image: "This is what the inside of the HTV looks like. 2600 kg of science, equipment and supplies, very neatly packed and strapped to resist a launch to space! For first ingress into a cargo vehicle – after we equalise the pressure and open the hatch – we always wear a mask and take samples of the atmosphere. Safety first! Some dust or small debris could have gotten loose and become a hazard for the crew, and the atmosphere might be somehow polluted. Not the case with our pristine HTV-6!"
