Initial weak signal was followed by abnormal signals difficult to interpret.

The mission operations team officially concluded intensive operations.

K-RadCube was developed under the supervision of KASI and operated by KT Sat.

Its mission was to measure space radiation at various altitudes.

It was equipped with Samsung and SK Hynix semiconductor chips for radiation testing.

It was South Korea's first operational scientific satellite in deep space.

K-RadCube was injected into an orbit requiring a thruster maneuver to raise perigee altitude.

If the maneuver failed, it was designed to re-enter the atmosphere.

Communication failure occurred before the maneuver could be executed.

The CubeSat was designed to survive the Van Allen radiation belts.

K-RadCube marked South Korea's first venture beyond Earth's magnetosphere.

The mission's failure raises questions about the maturity of South Korea's space science capabilities.
