On March 16, China successfully launched the “Hunan University of Science and Technology No. 2” satellite aboard a Kuaizhou-11 rocket from the Jiuquan Satellite Launch Center. The satellite entered its designated orbit and deployed its solar panels shortly after liftoff. It is China’s first spacecraft designed to extend the lifespan of other satellites by testing in-orbit refueling technologies.
The mission aims to demonstrate how to refuel satellites that have exhausted their fuel, addressing a growing challenge as the number of satellites—especially large constellations—continues to rise. Many satellites remain functional but are retired due to fuel depletion. The project seeks to reduce operational costs and improve the sustainability of space activities. Jointly developed by Hunan University of Science and Technology and a commercial aerospace company, the satellite is equipped with a flexible robotic arm capable of safely docking with target satellites for refueling. The arm mimics the movement of an elephant trunk or octopus tentacle, allowing for adaptable, low-impact contact that reduces the risk of collision.
In addition, the satellite carries an innovative “drag balloon” device designed to help mitigate space debris. The device inflates into a large, lightweight sphere, significantly increasing atmospheric drag and accelerating the reentry of any satellite that is at its final stage. This could shorten the deorbiting process from decades to about one year, offering a low-cost and scalable solution for disposing of defunct satellites and improving long-term orbital sustainability.
