Summary
The Lantan-1 satellite is a Chinese Earth observation satellite that was launched on January 17, 2025, from the Jiuquan Satellite Launch Center using a Long March 2D launch vehicle. It measures 0.5 meters in length and diameter, and has a dry mass of 66 kg. The satellite is equipped with solar panels for power generation and features a three-axis stabilization system.
The Lantan-1 mission aims to conduct remote sensing monitoring of water quality in estuaries, bays, and nearshore waters, as well as patrol sea discharge outlets. It carries a payload developed by the Hangzhou Institute of Advanced Studies for this purpose, enabling it to monitor water quality and detect any potential environmental hazards.
The satellite is owned by Hangzhou Dianzi University and was manufactured by GEESPACE using an aluminum alloy structure. It has successfully entered its designated orbit and is now operational, with a lifetime not specified in the available information.
