25 November 2025 – Alén Space has completed the manufacture of ETRISat, a 6U CubeSat fully developed at its facilities in Nigrán (Spain) for the Electronics and Telecommunications Research Institute (ETRI), one of South Korea’s leading public research organisations. The satellite has already been delivered to ETRI and is now in South Korea awaiting launch aboard a Nuri (KSLV-II) rocket from the Korea Aerospace Research Institute (KARI). Lift-off is scheduled for the coming days from the Naro Space Center, located in South Jeolla Province. ETRISat’s primary objective is the in-orbit demonstration (IOD) of communications technologies, aligned with ETRI’s initiatives focused on the evolution of satellite and maritime communication networks. One of the mission’s challenges is the verification of signal transmission via ocean buoys equipped to collect data such as seawater temperature and wave height. During the mission, these signals will be relayed to ETRISat and subsequently transmitted to ground stations, enabling the evaluation of their effectiveness for real-time climate and ocean condition monitoring.
