iSpace announced yesterday that their RESILIENCE lunar lander successfully completed a flyby of the Moon on February 15, 2025. RESILIENCE was launched aboard a Falcon 9 on January 15 from Kennedy Space Center, and has been traveling cislunar space since that time.

According to iSpace yesterday, “RESILIENCE is now on a trajectory out to deep space before completing orbital maneuvers that will bring it back towards the Moon in advance of lunar orbit insertion, expected around early May.”

RESLIENCE reached its closest point to the lunar surface thus far at 5:43 PM EST (2243 UTC) on Valenitine’s Day, coming within roughly 8,400 kilometers surface on its flyby, a historic first of its type for a Japanese private, commercial lunar lander. It now heads past the moon towards apoapsis and a return to cislunar space and lunar orbit. After that point, preparations for landing can begin.

The flyby was the fifth of ten major milestones for the spacecraft as it prepares to touch down on the lunar surface sometime in May or June of this year. The lengthy time between launch and landing is due to mission designers planning for a longer, energy-efficient trajectory to reach the lunar surface, one that reduced spacecraft complexity by eliminating the need to carry a much larger propulsive unit.

This will be the second landing attempt for iSpace. In April 2023, the first Hakuto lander successfully traveled from Earth and made a landing attempt, however, it crash-landed after its propellant was exhausted due to the spacecraft’s software misjudging the actual altitude of the spacecraft. After improvements and remediations, iSpace is hopeful for a successful landing in late Spring of this year.

Hakuto-R / RESILIENCE Mission Is Primarily A Technology Demonstration

iSpace’s mission with RESILIENCE in mainly one for technology performance and validation, demonstration commercial viability, and international collaboration and coordination. Undoubtedly, the iSpace team will learn a great deal more about real-world operation of their lander in Mission 2, and that in turn will inform future missions to come.

Demonstration of Advanced Landing Technology

One of the primary goals — if not the major goal — of the RESILIENCE mission is to demonstrate lunar landing capabilities. Secondly, iSpace hope to demonstrate landing with a high level of precision. The company has refined its autonomous landing system with lessons-learned from Mission 1. Their system leverages AI and real-time terrain recognition as part of a safe touchdown on the surface. Perfecting this technology is crucial for future robotic and crewed missions.

Testing of Lunar Surface Mobility and Resource Utilization

RESILIENCE plans to deploy small rovers and payloads to test surface mobility and in-situ resource utilization (ISRU) technologies. By analyzing the Moon’s regolith and extracting potential resources such as water ice, iSpace hopes to contribute to future lunar sustainability. ISRU is a key aspect of NASA’s Artemis program and other international lunar initiatives, as it could enable long-term human presence on the Moon.

Lunar Data Collection

By gathering environmental and geological data, the RESILIENCE probe will help improve scientific understanding of the Moon’s surface conditions. The mission will assess factors such as temperature variations, radiation levels, and dust behavior—all critical information for designing next-generation lunar habitats and infrastructure.

Supporting Commercial Lunar Activity

iSpace is focused on building a lunar economy, and RESILIENCE will serve as a proof-of-concept for future commercial deliveries to the Moon.

iSpace also plans to become a key player in the emerging lunar industry through collaborations with global space agencies and companies. The company is hopeful that the success of RESILIENCE could pave the way for future joint ventures and technological exchanges in lunar exploration.
