SUMMARY
The VASIMR (Variable Specific Impulse Magnetoplasma Rocket) requires approximately 15 megawatts of power to lift a 1-ton spacecraft off the Earth's surface, significantly exceeding the 200 kW version currently under development for space applications. This calculation is based on a thrust requirement of 10,000 Newtons and a specific impulse of 3000 seconds, resulting in an exhaust velocity of 30 km/s. The high specific impulse of VASIMR leads to a low thrust-to-power ratio, necessitating substantial power for terrestrial launches.
