NASA astronaut Ricky Arnold (@astro_ricky) took this selfie during the May 16, 2018, spacewalk to perform upgrades on the International Space Station, saying in a tweet “An amazing view of our one and only planet. #Spacewalk #EVA50.”

Arnold and fellow spacewalker Drew Feustel donned spacesuits and worked for more than six hours outside the station to finish upgrading cooling system hardware and install new and updated communications equipment for future dockings of commercial crew spacecraft.
