TOKYO -- Japanese Prime Minister Shinzo Abe and U.S. President Donald Trump are expected to sign an agreement on joint lunar exploration and other space-related projects when they meet here May 27, seeking to stay a step ahead of China and other rivals.
Japan will join the U.S.-led Gateway project, which involves putting a manned space station into lunar orbit to use as a base for missions to the moon and eventually Mars. This will mark the two countries' first collaboration on lunar exploration.
