ispace Completes Success 8 of Mission 2 Milestones
June 2, 2025 | ispaceEstimated reading time: 1 minute
ispace, inc. (ispace) (TOKYO: 9348), a global lunar exploration company, announced that the RESILIENCE lunar lander has successfully completed all orbital maneuvers while in lunar orbit and is now being prepared for its landing attempt on June 6, 2025.
This marks the completion of Success 8 milestone of Mission 2 “SMBC x HAKUTO-R Venture Moon.”
RESILIENCE conducted a lunar orbital control maneuver at 5:27 p.m. JST (08:27 UTC) on May 28, 2025, to move into a circular orbit around the Moon in accordance with the mission operation plan. The operation required an engine burn of approximately 10 minutes, the longest to date on Mission 2. Since then, the lander has been in a 100 km orbit around the Moon and completes a full orbit every 2 hours. After RESILIENCE completed the orbital control maneuver, ispace engineers in the Mission Control Center in Nihonbashi, Tokyo, Japan worked to confirm the precise orbit in advance of the landing sequence.
The RESILIENCE lander, which reached lunar orbit on May 7, 2025 (JST), orbited the moon in an elliptical orbit with a perilune (closest point to the moon) altitude of approximately 70 km and an apolune (farthest point from the moon) altitude of approximately 5,800 km. After performing three orbital control maneuvers, it reached a circular orbit around the moon at an altitude of approximately 100 km.
A lunar landing is scheduled for no earlier than June 5, 2025 (UTC) (June 6, 2025, JST). The RESILIENCE lander is scheduled to begin descent from its current circular orbit. During the descent phase, the lander will automatically fire its main propulsion system to gradually decelerate and adjust its attitude, with the goal of achieving a soft landing on the lunar surface.
“Having completed eight of 10 mission milestones, RESILIENCE is now ready to attempt a historic landing on the Moon, carrying not only the payloads of our customers but also the hopes of our employees, their families, our partners and all of our supporters,” said Takeshi Hakamada, Founder & CEO of ispace. “We have leveraged the operational experience gained in Mission 1 and during this current voyage to the Moon, and we are confident in our preparations for success of the lunar landing.”
