Event Overview
A Japanese startup aimed for a lunar milestone but faced adversity as its lander, Resilience, likely crashed during its attempt to touch down on the Moon on June 5. This attempt was seen as a chance at redemption for ispace, following a prior unsuccessful mission in April 2023.
Mission Details
The planned landing was timed for 3:17 p.m. Eastern at Mare Frigoris, a region situated approximately 60 degrees north on the moon's near side. Once operational on the lunar surface, Resilience was designed to function for about two weeks, leveraging solar energy until the sun set on its location.
Initially, the landing sequence appeared to proceed according to plan. However, telemetry data shared during ispace's live webcast revealed alarming information: the lander descended at an unsafely high speed of 187 kilometers per hour, approximately one minute and 45 seconds before the intended touchdown, leading to a loss of communication.
Technical Challenges Faced
In a statement released about five hours post-landing attempt, ispace confirmed fears of the lander being lost. They indicated the crash resulted from difficulties with a laser rangefinder, which failed to accurately gauge the distance to the lunar surface, hindering the lander from decelerating to a safe landing velocity. After that communication gap, officials noted that telemetry signals ceased entirely.
Takeshi Hakamada, ispace's founder and CEO, emphasized the priority of analyzing available telemetry data to pinpoint the cause of this second landing attempt failure. The statement coincided with a press briefing in Tokyo, where executives acknowledged the need for further technical analysis without delving into specific possible causes.
Comparison to Previous Missions
This incident mirrors a previous setback during the launch of a similar lander back in April 2023, which crashed due to a software mishap that misled the vessel into thinking it had reached the lunar surface while still five kilometers above it. Ryo Ujiie, the company's chief technology officer, remarked that the issues in this latest attempt seemed different, primarily attributed to the newly designed rangefinder that had been developed after the previous mission's failure.
Launch Background and Payloads
Resilience was launched aboard a Falcon 9 rocket on January 15, 2023, and initially shared the launch with Firefly Aerospace’s Blue Ghost 1 lunar lander. In a favorable turn, Blue Ghost successfully achieved lunar landing on March 2, while Resilience followed a less fuel-intensive trajectory, actually performing a lunar flyby on February 14 that further distanced it 1.1 million kilometers from the Moon.
Future Missions and Objectives
Looking ahead, ispace has ambitious plans for subsequent lunar missions. The company is developing a new lander, named Apex 1.0, slated for a 2027 NASA Commercial Lunar Payload Services mission. Concurrently, in Japan, they’re also designing Series 3, supported by an $80 million grant from the Japanese government, aimed at Mission 4 in 2027.
Despite the recent failures, ispace’s representatives remain optimistic. Jumpei Nozaki, the chief financial officer, highlighted that the company holds a competitive advantage due to the limited number of firms capable of developing lunar landers. Successful missions in the near future could undoubtedly foster trust and reliability among potential clients seeking to utilize ispace’s services.
While the task of landing on the Moon is inherently complex, Hakamada reassured audiences that successes from others, including American companies and Japan's space agency JAXA, provide motivation for finding solutions to current challenges. "It’s important to learn from each setback," he noted. "Our focus now is on identifying the reason for this latest failure and using that insight to ensure the success of forthcoming missions," he concluded, framing the narrative toward resilience and persistence in space exploration.
Conclusion
The mission of ispace and similar organizations reflects the profound challenges of space travel, particularly in targeting the Moon. Each failure continues to add depth to the understanding of extraterrestrial landings, highlighting both the risks and the opportunities that come with exploration.
