How fast could a nuclear powered spaceship go?
Theoretical applications
| “Energy Limited” Orion | |
|---|---|
| Maximum velocity (kilometers per second) | 1000 km/s (=0.33\% of the speed of light) |
| Mean acceleration (Earth gravities) | 0.00003 g (accelerate for 100 years) |
| Time to Alpha Centauri (one way, no slow down) | 1330 years |
| Estimated cost | 1 year of U.S. GNP (1968), $3.67 Trillion |
Is ion thruster possible?
Ion thrust engines are practical only in the vacuum of space and cannot take vehicles through the atmosphere because ion engines do not work in the presence of ions outside the engine; additionally, the engine’s minuscule thrust cannot overcome any significant air resistance.
How long would it take to travel to Mars with nuclear rockets?
As a result, nuclear rockets travel twice as fast as chemical-driven spacecraft. Thus, a nuclear rocket could make a trip to Mars in as little as four months, and a trip to Saturn in as little as three years (as opposed to seven years).
Could nuclear propulsion help get humans to Mars?
Nuclear Propulsion Could Help Get Humans to Mars Faster As NASA’s Perseverance rover homes in on the Red Planet, engineers on the ground are furthering potential propulsion technologies for the first human missions to Mars. NASA is looking at two types of nuclear propulsion systems – nuclear electric and nuclear thermal propulsion.
Why are nuclear rockets better than chemical rockets for space travel?
Moreover, chemical rockets are slow, making long trips to places like Mars impractical for manned missions. A more feasible technology is nuclear propulsion. Nuclear rockets are more fuel efficient and much lighter than chemical rockets. As a result, nuclear rockets travel twice as fast as chemical-driven spacecraft.
Could we travel to Mars in less than a second?
A NASA scientist has cooked up plans for a bonkers new rocket engine that can reach close to the speed of light — without using any fuel. Travelling at such speeds, the theoretical machine could carry astronauts to Mars in less than 13 minutes, or to the Moon in just over a second.
