China’s (and globally) first synthetic aperture radar (SAR) satellite being put into geosynchronous orbit. It can provide unprecedented all-time Earth observations of an area near the same longitude and can provide unique non-interrupted observations for various uses.
Geosynchronous Transfer OrbitLuna 25 (ex-Luna-Glob) was a lunar lander mission by the Russian Federal Space Agency (Roscosmos) that crashed into the lunar surface after an anomalous orbital maneuver placed it on a collision trajectory towards the Moon. It was scheduled to land near the lunar south pole at the Boguslavsky crater to prove lunar landing technology. The mission carried 30 kg of scientific instruments, including a robotic arm for soil samples and possible drilling hardware. It was planned to remain active for at least one year on the lunar surface.
