Summary:
- Elon Musk, the CEO of SpaceX, has proposed the idea of building a satellite catapult on the moon.
- The catapult would use the moon's low gravity and lack of atmosphere to launch satellites into space more efficiently and at a lower cost compared to traditional rocket launches.
- This idea is not entirely new, as scientists have been exploring the concept of using the moon's environment to launch payloads for decades, but Musk's proposal has brought renewed attention to the idea.
