At the end of April, a Japanese company ispace announced that the lander attempt Hakuto-R the landing on lunar soil was unsuccessful and his plane crashed. The company is now disclosing an analysis of what could have caused the probe to fall, saying the accident was due to an incorrect definition of lunar soil on a modular system.
Hakuto-R is believed to have touched down at an altitude of 5 km.

According to the company, itThe probe normally completed the entire deceleration process for landing and activated the descent sequence when it was at an altitude of about 100 kilometers and was able to slow down to less than 3.6 km/h. But when he was 5 kilometers from the ground, the model software did not read him correctly and thought he landed while still in flight.
It did Hakuto-R continue to slowly descend towards the Moon’s soil until its propulsion system runs out of fuel, causing the model to freefall. This problem arose at the predicted time when ispace will lose contact with the probe, but the company has since been unable to contact the module, indicating that it was badly damaged in the crash.

The company is not sure what caused the system reading problem, but the Japanese manufacturer believes the problem was the cliff the model flew over and confused the software.
When passing the highest point, the spacecraft determined the distance of 3 kilometers from the earth, which the system considered incorrect and activated its anti-anomalous protection system. This resulted in a larger than expected discrepancy between the measured altitude value and the calculated altitude value set in advance.
On their official website ispace indicates that Mission 1 – what is the module Hakuto-R – successfully completed eight out of ten landing stages. The company notes that the rig performed well in several low-altitude maneuvers and the errors that caused the accident will be corrected. Mission 2which is expected to be released in 2024.
