日本民企挑战月表着陆再次失败

Core Points - The Japanese space technology startup "iSpace" faced another failure in its lunar lander "Hakuto-R" attempt to land on the moon's surface on June 6 [1] - The CEO of "iSpace," Takashi Okada, indicated that telemetry data disappeared suddenly before landing, leading to the conclusion that a hard landing on the moon likely occurred [1] - The specific reasons for the landing failure are still under investigation [1] Mission Details - The mission named "Hakuto-R Lunar Exploration" was a follow-up to the previous attempt with "Hakuto-R 1" in December 2022, which also failed to complete the lunar landing [1] - The "Hakuto-R" lander was launched on January 15, 2025, aboard SpaceX's Falcon 9 rocket and entered lunar orbit on May 7 [2] - The lander was equipped with several payloads, including a mini lunar rover, a water electrolysis device for the lunar surface, and a deep space radiation detector, with the planned landing site in the "Mare Frigoris" in the northern hemisphere of the moon [2] Technical Issues - It was confirmed that the laser altimeter measuring the distance between the lander and the moon's surface experienced delays, and the lander did not decelerate sufficiently to achieve the necessary landing speed [2] - The lander began its descent from an altitude of approximately 100 kilometers to about 20 kilometers, where the main engine ignited as planned, but telemetry data was lost during the descent [1][2]
