Japanese astronomical satellite Hitomi was lost after the collapse of orbiting during an uncontrolled rotation.
Data were transferred shortly after the separation of the tool from the back of the probe satellite.
This fact is important for two reasons.
First, the Japanese astronomical satellite Hitomi was on the other side of the Earth from Japan.
Hence, there was no active monitoring from the ground situation.
This can lead to disruption of the onboard electronics.
STT systems and IRU disagreed over the position of the satellite.
The position control system tried to stop the satellites rotation using flywheels.
However, the information loaded earlier was wrong, as the flywheels only increased the wheel.
Ultimately, the rotation speed exceeds the design parameters.
