Radical Idea Shows Laser Propulsion Could Rapidly Accelerate Trips to Mars

Posted by in category: space travel

NASA and China plan to mount crewed missions to Mars in the next decade. While this represents a tremendous leap in terms of space exploration, it also presents significant logistical and technological challenges.

For starters, missions can only launch for Mars every 26 months when our two planets are at the closest points in their orbit to each other (during an “Opposition”). Using current technology, it would take six to nine months to transit from Earth to Mars.

Even with nuclear-thermal or nuclear-electric propulsion (NTP/NEP), a one-way transit could take 100 days to reach Mars.
