Perfectly functional spacecraft have to cease operations because they run out of propellant for stationkeeping. Now a Chinese satellite has demonstrated practical orbital refueling. The recently launched Shijian-25 satellite docked with the Beidou-3 G7 at geosynchronous orbit and transferred 142 kilograms of hydrazine, extending the communication satellite's lifespan by 8 years. China is planning to build a network of "space gas stations" to maintain its fleet.
