Feynman Explains Why You Can’t Come Back from Mars | RICHARD FEYNMAN

Описание: Landing on Mars is only half the mission.

The real challenge is getting back.

In this video, inspired by Richard Feynman's clear and curiosity-driven style of explaining science, we explore why returning from Mars is one of the hardest engineering problems ever imagined.

We'll examine the physics of escape velocity, the enormous amount of fuel required, Mars' thin atmosphere, life-support constraints, launch windows, radiation exposure, and why every kilogram sent to Mars dramatically increases mission complexity.

From orbital mechanics to rocket science, discover why the return journey is often considered even more difficult than the trip there.
