Japanese company ispace is revamping its lunar lander plans while introducing a lunar satellite network. The company said Friday it was replacing an engine called VoidRunner that it has been jointly developing with Agile Space Industries for its landers in favor of a flight-proven engine from another, unnamed company. The company, which had separate lander designs from its Japanese and American business units, is combining them into a unified platform called Ultra. As a result of the change, it is delaying the first ispace U.S. lander, which it was building for Draper for a NASA mission, from 2027 to 2030. Japanese landers launching in 2028 and 2029 remain on schedule. ispace also announced it is developing Lunar Connect Service, a constellation of five satellites to provide communications, navigation and imaging services at the moon. The first satellite is scheduled to launch in 2027.
