The micro-satellite mounted on the Korean launch vehicle Nuri has successfully separated.
The Ministry of Science and ICT and the Korea Aerospace Research Institute announced that they confirmed that the Chosun University team's micro-satellite was successfully separated from the performance verification satellite launched by the Nuri on the 21st.
The micro-satellite was separated yesterday (29th) around 4:50 pm, and finally received some status information from the ground station around 3:48 am today.
The signal sent by the micro-satellite contained information such as the satellite's mode, attitude, and battery mode.
However, as for the reception of only some of the initially targeted signals, the satellite's current state is rotating rapidly, making it difficult to communicate smoothly in both directions.
Hangangwooyeon plans to try to communicate again at 3:48 and 5:26 pm today, receive status information, and deliver a communication order.
It is known that micro-satellites are structurally less reliable than commercial satellites, so it is not easy to determine the exact cause of failure.
The performance verification satellites mounted on the Nuri launch include 4 ultra-small satellites developed and manufactured by Korean university research teams.
Chosun University, Yonsei University, Seoul National University, and KAIST 4 labs created micro-satellites orbit in outer space to perform their respective missions, such as fine dust observation and tsunami observation.
This time, the launched satellite is a satellite called 'Step' of the Chosun University team, and aims to observe signs of eruption of Mt. Baekdu using a broadband infrared camera.
