Nuclear-powered rocket concept could cut journey time to Mars in half

Buckle up, space nerds—your dream of zipping to Mars faster than a pizza delivery is closer than ever! A UK startup called Pulsar Fusion is cooking up Sunbird, a nuclear fusion rocket that promises to slash the Mars commute from “Are we there yet?” to “Wow, that was quick!” Using just grams of fuel and the power of star-mimicking magic, this bad boy could hit 500,000 miles per hour—making NASA’s chemical rockets look like they’re pedaling a tricycle in the space race.
