What is it? A new concept that will allow traveling to spacecraft much faster. Caltech scientists developed it. Interesting candles use lasers to propel space probes in the miniature. Coupled to “light -driven candles” reach ultra -granted speeds.
«The candle of light will travel faster than any previous spacecraft. Open interstellar distances for direct space exploration. Now you can only access by remote observation, ”Harry Atwater explains in a statement. He is scientist in Caltech.

Laser
“It must support heat, maintain its shape under pressure and move stable along the axis of a laser beam.” It is necessary to understand how the materials to the radiation pressure of the lasers respond. This was already determined. An article that describes the work appears in the journal Nature Photonics.
The objective is to characterize the behavior of a candle of light that moves freely. A miniature light candle was created that is tied in the corners inside a larger membrane. It is a silicon nitride membrane of just 50 thick nanometers. Something that looks like a microscopic springboard.
The candle acts as a mechanical resonator, vibrating like a springboard when it is beaten by the light. «The device represents a small candle of light. We made a scheme to accurately measure the movement induced by long -range optical forces ».

Fast trip
In the article, the researchers propose the hypothesis of which part of the beam, when it is directed at an angle, hits the edge of the candle. This causes a part of the light to be dispensed and sent in other directions.
Interesting light candles are the future of space exploration. Looking ahead, the equipment hopes to use nanoscience and metamaterials to complete the design. These are carefully designed materials on a tiny scale to have desirable properties. They hope to control the side by side movement and the rotation of a miniature light candle.
