A Chinese Satellite Tests Orbital Refuelling

Satellites often face a disappointing end: despite having fully working systems, they are often de-orbited after their propellant runs out. However, a breakthrough is on the cards with the launch of China’s Shijian-25 satellite which has been launched into orbit to test orbital refuelling operations.

It’s success will mean China plans to develop a network of orbital refuelling stations! More
