The Korea AeroSpace Administration (KASA) announced that the Next-Generation Medium Satellite 3 (CAS500-3), launched aboard the Korean launch vehicle Nuri at 1:13 AM on the 27th (KST), successfully reached its target orbit. Furthermore, two-way communication with the King Sejong Station ground station in Antarctica was successfully established around 1:55 AM. Communication with five of the twelve secondary/piggyback satellites launched alongside it has also been confirmed.
First, following the initial contact, CAS500-3 achieved an additional successful communication around 2:48 AM via the antenna at the KARI (Korea Aerospace Research Institute) ground station in Daejeon. To date, the satellite has conducted two-way communication twice with the KARI ground station and 12 times with overseas ground stations (King Sejong Station in Antarctica, and Svalbard in Norway).
During the communication sessions today, the functionality of the CAS500-3 main body components was confirmed. Detailed status information will be downloaded, and precision checks will be performed through additional communications with the Daejeon KARI ground station and others.
Following a two-month period of initial operation, the satellite will undergo payload checks and mission preparation. It will then enter full-scale space science mission activities for one year, orbiting the Earth approximately 15 times a day in a Sun-Synchronous Orbit .
CAS500-3 is equipped with the following payloads to perform space science and technology verification missions:
BioCabinet: Verification of 3D differentiation and culture of stem cells based on bio 3D printing.
IAMMAP : Space plasma-magnetic field measurement instrument.
ROKITS : Space-based wide-field airglow observation instrument.
In addition, the development organizations responsible for the 12 secondary/piggyback satellites have initiated initial ground station communication and performance checks.
Among the 12 secondary satellites, five satellites—manufactured by the Electronics and Telecommunications Research Institute (ETRI), Cosmoworks, Inha University, and KAIST—have also completed communication with their respective ground stations.
