The Rocket-Less Future of Space Travel | What the Physics?! | NOVA | PBS

From NOVA PBS Official.

Space elevators? Nuclear rockets? The future of space travel could look radically different.

Imagine taking an elevator to space. Or blasting off in a nuclear rocket. That might sound like science fiction, but scientists are racing to develop new, more efficient methods of space travel – and some pretty wild ideas are on the table. Discover the rocket-less future of space travel and the quest to make it happen. Hosted by Athena Brensberger ‪@astroathens 💫
