Russia Traces Luna-25 Crash to Onboard Control System Failure
Russia’s state space corporation Roscosmos has concluded that Luna-25 failed because the onboard control system did not receive required data from the accelerometer to trigger an engine shutdown at the correct time. Russia’s first lunar probe in almost 50 years, Luna-25 was trying to lower its orbit around the Moon in preparation for landing two days later, but instead crashed into the surface.
