NASA knows a way to get humans to Mars in about a month, and to land unmanned probes in just three days.

In a NASA 360 video University of California Santa Barbara professor Philip Lubin describes the process of "photonic propulsion." It involves propelling objects with mass-free particles of light (photons). Basically, pushing spaceships with a great, big laser.

Lubin explains that the proposed system would require about the same amount of energy as the upcoming Space Launch System to get to "relativistic speeds." Which is to say speeds matching a significant percentage of the speed of light. In this case, 30 percent in about 10 minutes.

That speed is totally unheard of as far as human technology goes. And at a relatively reasonable energy cost, it sounds too good to be true. So what's the catch? According to Lubin there doesn't appear to be one. At least none that we couldn't overcome.

"There is no known reason why we could not do this," Lubin says in the video.

Lubin has a far more detailed roadmap on the subject, if you're interested in the specifics. Though the broad benefit is this: at that speed we could scout, and perhaps one day reach potentially habitable exoplanets light years away from Earth.

Awesome news.

The man can be going outside this space only with the help of speed. There are different speed rockets which works for crossing the earth and went into space. This speed works and brings rocket or space ship outside the earth. In space the things become weightless.

I am very interested in all the information written on this page, for that I can only say thank you to all those I've read on this page.
