Scientists create laser system that could get to Mars in just 45 days

predicts it would take about 500 days for humans to reach the Red Planet, but Canadian engineers say a laser-based system could cut that journey to just 45 days.

The US space agency is planning to send a crew to the Red Planet in the middle of the 2030s, around the same time also plans to land humans on .

Engineers from McGill University, in Montreal, , say they have developed a 'laser-thermal propulsion' system, where lasers are used to heat hydrogen fuel.
