China has successfully retrieved two satellites that were damaged after a failed rocket launch in March 2024. The operation, which lasted for 123 days, utilized a novel navigation technique to guide the satellites back into their intended orbits.
The satellites, known as DRO-A and DRO-B, were part of China’s growing space program aimed at improving space navigation precision. Initially, they were placed in a distant retrograde orbit (DRO), providing coverage between Earth and the moon for autonomous spacecraft and future lunar missions.
After the launch malfunction, the satellites strayed off course, but Chinese scientists used gravitational forces to slingshot them back on track. The team worked nonstop for two consecutive nights to devise multiple potential routes for mission control to choose from.
Thanks to their innovative navigation technique, China was able to rescue both satellites, saving years of effort and millions of dollars invested in the mission. The operation has marked a significant success for China’s space program and its commitment to advancing space exploration technology.
