Update from ispace about the failed HAKUTO-R M2 mission -

After decelerating from 20 km altitude to near vertical attitude, telemetry was lost.

The laser rangefinder used to measure the distance to the lunar surface experienced delays in obtaining valid measurement values. As a result, the lander was unable to decelerate sufficiently, crashing on the lunar surface at ~187 km/h.

The table in post #6 gets another red row 🙁.

The ispace HAKUTO-R mission 1 crash-landed for a different reason on April 25, 2023.

Around 5 km altitude, the onboard software incorrectly presumed that the radar altimeter was faulty because its reading of 5 km diverged from that of the inertial measurement unit. The spacecraft descended slowly thinking it was near the surface, ran out of fuel and then crashed into the lunar surface at more than 100 meters per second.
