The cluster represents a significant step forward in solid propulsion technology. By balancing chemical stability with high reactivity, it provides a viable alternative to toxic legacy fuels. Future development will focus on the scalability of cluster synthesis for commercial aerospace applications. References

Hypergolic fuels, which ignite spontaneously upon contact with an oxidizer, are essential for spacecraft maneuvering and satellite positioning. Traditional systems often rely on toxic hydrazine-based fuels. Recent research has shifted toward metal hydride clusters, specifically Copper-based clusters , due to their potential for high energy density and reduced environmental impact. 2.
