Japanese astronaut Soichi Noguchi on Wednesday installed a robotic arm outside the country’s Kibo laboratory module on the International Space Station, the Japan Aerospace Exploration Agency said. Working together with NASA astronaut Timothy Creamer, the 44-year-old Noguchi opened the air lock for the first time, brought out the 2.2 meter-long arm into a space and attached it at the tip of a longer, 10-meter arm. The installation of the smaller arm is aimed at allowing astronauts to engage in more delicate operations, including fixing problems with experimental devices, from inside the space station.
