U.S. and Japanese astronauts conduct spacewalk to fix robot arm on ISS

WASHINGTON – Two astronauts from Japan and the United States went on a spacewalk Friday to repair the International Space Station's robotic arm and put equipment in storage. The spacewalk was the first for Japanese Aerospace Exploration Agency (JAXA) astronaut Norishige Kanai and the fourth for his U.S. counterpart Mark Vande Hei. The outing began at 7 a.m. when the duo switched their spacesuits to battery power before venturing into the vacuum of space. The excursion was expected to last 6½ hours. Kanai, 41, is a doctor and diver who goes by the nickname "Neemo."
