This vehicle was also responsible for transporting a lesser-known mission to the Moon, known as the Longjiang twin spacecraft. This package consisted of two satellites designed to fly in formation and validate technologies for low-frequency radio astronomy.
While Queqiao flew beyond the Moon to act as a communications relay for the Chang’e-4 lander, the Longjiang satellites were to enter orbit around the moon. On July 31st, 2019, after more than a year in operation, the Longjiang-2 satellite deorbited crashed on the lunar surface. And thanks to efforts spacecraft tracker Daniel Estévez and his colleagues, the Lunar Reconnaissance Orbiter (LRO) was able to photograph the impact site.
