One day we could reach Mars in just three days by using a system known as "photonic propulsion", Nasa scientist Philip Lubin has said. In a video for Nasa 360, he explains how we could use particles of light to push objects through space. The video, which was released earlier this month, follows a paper written by Lubin in April last year. In A Roadmap to Interstellar Flight, he says that while incredible feats in space travel have been achieved, with our current propulsion technology we will never reach our nearest stars.

He proposes a programme that will allow for spacecraft that can reach speeds faster than 1,000 km per second. "These systems can be propelled to speeds currently unimaginable with existing propulsion technologies. To do so requires a fundamental change in our thinking of both propulsion and in many cases what a spacecraft is," the paper said. At present, the fastest Nasa could get humans to Mars is around five months. Researchers are currently working on technologies that will allow for a manned mission to the Red Planet in the 2030s.

However, Lubin says photonic propulsion could vastly decrease the time it takes to get there. This system involves shooting Earth-orbiting lasers at extremely thin spacecraft to propel them at extremely fast speeds through space.

A normal spacecraft moves forward by firing a propellant away from the direction it wants to travel. Photonic propulsion would work in the same way, only using lasers from Earth. This would mean the spacecraft could accelerate for longer and reach far higher speeds. It would also mean carrying heavy fuel on board would not be necessary. While this technique would only work to push small objects at the moment, he said it could be scaled up in time to use on larger vessels. "We could propel a 100kg aircraft to Mars in a few days," he said. It would not, however, be used for manned flights. More likely, it could potentially be used to send probes to distant galaxies to find potentially habitable planets and so forth. "There are recent advances that take this from science fiction to science reality," Lubin said. "There is no known reason why we can not do this."

Cool.

But I guess the laser propulsion fired from earth should result in the spacecraft and the laser beam moving in same direction...as opposed to conventional jet propulsion systems.

It's all lie. Nasa has said that they couldn't pass through the van allen radiation belt. In that case, how did they get to the space and the moon? You dogmatic Nasa's followers should wake up.

Apollo crews had dosimeter on them which they used for radiation readings and the mission was successful.

NASA's Van Allen Probes discovered a third radiation belt in 2013,it was destroyed a month later when it entered the inner radiation belt.That was enough time to study how electrons are affected by solar wind.

More studies are still being made though.

Apollo rocketed through the Van Allen Belts & not one single astronaut was affected by the radiation. The initial solution was to limit missions to an altitude safely below the inner belt, which begins at about 345 miles above the planet. Some months after the inception of that safety method, they decided to visit the Moon which is about a quarter of a million miles away, and which meant sending men clear through both Van Allen belts. That's when Robert O. Piland and Stanley C. proposed that some sort of feasible shield be designed to protect the crew from the outer belt especially. There were also trajectory analyses done beforehand to determine what pathways were the safest to navigate through.

They should have simply cleared the radiation by detonating a nuclear payload in the vicinity like Van Allen proposed, instead of the 1962 Atomic energy commission test which only aggravated the problem.

But NASAs weren't the first on the moon. The Russians were!
