Fusion Gets Us to Mars in a Month or Less

Añadido: 2026-05-06

[00:00:00]Getting to Mars with chemical rockets takes 8 and 1/2 months, but with nuclear fusion, it takes 1 month or less. Space travel runs into a brutal physics problem.

[00:00:09]You need a lot of fuel to change your velocity, but the fuel itself has mass, so you need more fuel to carry the fuel.

[00:00:15]With chemical rockets heading to Mars, nearly 75% of your spacecraft's total mass has to be propellant.

[00:00:22]You're basically flying a giant gas tank with a tiny payload strapped on top.

[00:00:26]NASA's 1970s nuclear fission engine was designed to cut the Mars trip from 8 and 1/2 months to three or four.

[00:00:33]But fusion is where everything changes.

[00:00:35]Fusion propulsion designs only need a tiny fraction of the propellant, meaning you can fire your engines for the entire trip instead of just coasting, and you can reach Mars in about a month, potentially even a week, depending on a full development of fusion tech.

[00:00:50]Where chemical rockets hit a wall, nuclear rockets break through. Our full breakdown on why nuclear power is the key to mankind's future in space is now live on the Promethean Action Science channel. Get the link below.
