Why Returning From Mars ls Impossible - Feynman's Warning

Описание: Why Returning From Mars ls Impossible - Feynman's Warning
You've seen the headlines: "Mars by the end of the decade." There's just one detail they keep glossing over — actually coming back. And the physics of that return trip is staggering. It's not a bigger Moon mission. It's an entirely different beast, governed by an equation that punishes ambition exponentially.
In this video, we explore the real engineering nightmare of a Mars return mission, drawing on the fundamental physics Feynman championed throughout his career — the kind of honest, no-shortcuts confrontation with how nature actually works. We examine the Tsiolkovsky rocket equation, the tyranny of exponential fuel requirements, and why Mars's thin atmosphere creates a worst-of-both-worlds landing problem that doesn't scale for human missions.
