TOKYO (AP) — Japan's space agency is considering an unmanned mission to the moon by 2018 or early 2019, part of an effort to beef up aerospace technology and keep pace with China and other emerging powers. Japanese media reported Tuesday that JAXA presented the proposal to a government panel of the Ministry of Education, Culture, Sports, Science and Technology on Monday. [...] the public broadcaster NHK showed satellite images of the Japanese islands, alit at night, and of the aurora borealis, or Northern Lights, as possible attractions for passengers of space flights.
