The fine folks at NASA are working on a new and improved Positron powered space ship for the future mission to Mars.

Typically, a Positron drive would create power through Gama ray emissions.

Gama rays are extremely dangerous, can pass through most any type of matter on Earth, and tend to break cells down, which is obviously not a healthy side effect.

Today NASA is working on a new and improved drive that would create less powerful Gama Rays with a less dangerous side effect.
