NASA’s yearlong spaceman, Scott J. Kelly, took his first spacewalk Wednesday just hours before setting a new U.S. flight record.
Kelly and Kjell Lindgren tackled a long overdue list of maintenance chores outside the International Space Station. They removed insulation from an electronic switching unit and covered an antimatter and dark matter detector, before starting a grease job on the station’s big robot arm and some cable routing for a future docking port.
Kelly’s identical twin, Mark (pictured below), a retired astronaut, urged his brother to be careful but still have fun outside.
“Don’t forget to take a good selfie!” Mark said via Twitter. He commanded the mission that delivered the antimatter-hunting Alpha Magnetic Spectrometer in 2011; it was the next-to-last shuttle flight. Scientists wanted the device covered with a thermal blanket to keep it cooler and prolong its life.
