Space travel has, in some ways, changed very little from the 1950s. It still requires big, expensive, inflexible rocketry to project us out of the Earth’s atmosphere and into the cosmos.
If more than a handful of us are going to experience what it feels to enter space, says entrepreneur and space explorer Anousheh Ansari, the way we make that journey will have to change. Rockets may have to be replaced with other technology, such as elevators that can take us into the top layer of the atmosphere.
Ansari says that as the world’s population grows we will need to find new resources – and finding cheaper and easier ways to get into space is in our best interests.
