10. Reusable Rockets

Impact Score: 51

Reusable rockets have the potential to revolutionize space exploration and make it more accessible and affordable. By reusing the most expensive part of a rocket, the first stage, companies can drastically reduce the cost of launch. This opens up new possibilities for scientific research, satellite deployment, and even human spaceflight.

SpaceX is the leader in reusable rocket technology, having successfully landed and reused the first stage of its Falcon 9 rocket over many times. SpaceX also plans to develop a fully reusable Starship spacecraft, which could be used for missions to the Moon and Mars.
