Reducing the amount of time astronauts spend in spaceflight is critical to their health. Spending almost two years in spaceflight exposes them to high levels of solar and cosmic radiation, zero-gravity effects, and isolation, leading to risks of cancer, nervous system damage, and more, according to NASA.
The Pulsed Plasma Rocket (PPR) could revolutionize space exploration by significantly reducing travel time to Mars to two months. This new propulsion system generates thrust efficiently using superheated plasma pulses, with NASA investing in its development to optimize the design and perform experiments.
