Space elevators could be the next big innovation in space travel. They would revolutionize how we sent payloads into space, by dramatically reducing the cost and conserving energy. New experiments on the International Space Station are setting out to see how they work in space. In the near future, we could build a space elevator with new technology, similar to carbon nano-tubes.
This relates to engineering because it would revolutionize space travel and utilize the emerging technologies to build a space elevator.
