This episode has at its core the implications of Tsiolkovsky’s rocket equation, which figures the hard limits of rocket-based payload transportation to Earth’s orbit.

Furthermore, rockets are expensive, up to failure, risky and carry too little payload.

Making rockets more efficient reminds analogically of Henry Ford’s classic:

“If I had asked people what they wanted, they would have said faster horses”.

One of the non-rocket approaches to get a fast, cheap, safe and repeatable transport to orbit is the Space Elevator concept which we are going to cover in the episode with our guest, the amazing Josh Bernard-Cooper, a University of St Andrews Physics and Philosophy student, International Space University alumni and Research Assistant at the International Space Elevator Consortium.
