China develops electromagnetic launch system to cut rocket fuel costs

China is developing an electromagnetic launch system designed to accelerate rockets to supersonic speeds before their engines ignite. The ground-based technology relies on electrical power rather than conventional chemical propulsion, setting it apart from systems used by companies like SpaceX. The approach could significantly lower the amount of onboard fuel required for launches, potentially reducing overall costs. Testing of the system is reportedly underway, and a successful outcome could mark a major shift in how humans access space.
