Astronaut Soichi Noguchi has been selected to take part in a six-month mission aboard the International Space Station starting around the end of 2019, Japan's space agency said Tuesday. It will be the third ISS mission for the 52-year-old, following earlier expeditions in 2005 and 2009. Training for the mission, which will be carried out in both Japan and the United States, starts from Nov. 20. "I am extremely honored as I may be able to witness a big turning point in the history of manned space flights," Noguchi said. Noguchi will be responsible for maintaining ISS facilities, including the Japanese laboratory module Kibo, as well as conducting experiments and operating the station's robotic arm.
