A second mini satellite released from an orbiter mounted on Nuri has transmitted a signal to a ground station in Daejeon.
According to the nation's science ministry and KAIST, the first beacon signal from the cube-shaped satellite was received at 3:42 a.m. Saturday.
The CubeSat, named "Randev," developed by a KAIST team, successfully separated from the performance verification orbiter at 4:38 p.m. Friday.
So far, around a dozen beacon signals have been received through the ground station.
The signals confirm the satellite's voltage and temperature are normal.
KAIST also developed South Korea's first satellite, nicknamed "Our Star."
The team vows to continue to be a leader in the field of space research.
