The Japanese lunar lander startup Ispace has won a new customer for its next attempt to soft-land on the Moon, with the South Korean startup Unmanned Exploration Laboratory (UEL) signing a contract to put its proposed two-wheeled rover on that mission.
Under the terms of the agreement, the UEL rover will be integrated as a commercial payload on ispace’s ULTRA lunar lander for Mission 3, currently scheduled to launch in 2028. The mission would mark the first Korean rover to explore the Moon’s surface and underscores the growing commercial collaboration between Japan and Korea in the aerospace industry.
Mission 3 will serve as the inaugural flight for ispace’s ULTRA lunar lander.
Ispace so far has a very mixed record. It has successfully gotten two landers to the Moon, but both failed just before landing. It has also recently had to delay its lander mission for NASA because it had to replace the lander’s engine, the previous engine found to be inadequate.
Ultra is Ispace’s new larger lander design, intended to fly on all future missions. It remains untested in flight. The company presently has lander contracts for the following missions:
- 2028: a Japanese mission funded by Japan’s Ministry of Economy, Trade and Industry
- 2029: a Japanese mission funded by Japan’s Space Strategy Fund (designed at encouraging the private space sector
- 2030: NASA’s mission, being built in partnership with the American company Draper
At the moment, everything about Ispace remains tentative. It needs to finally land something on the Moon to truly establish itself.
