One month after launching into space, the sunny sail of the American organization Planetary society On Tuesday it was correctly deployed in orbit around the Earth.

Solar candle, called LightSail 2, is a small satellite with a leaf 32 square meters They are made of very thin, light and reflective polyethylene terephthalate (PET), which must allow the device to move with a simple photon pulse.

This is an attempt to prove that this alternative propulsion technology is sufficiently developed for engines.

"The introduction is complete!", a tweetal organization. The data sent by the satellite confirmed the mechanical operation, which is expected to be visually confirmed by the photographs later to be made by the probe.

Director of the Planetary Society, Bill nyeLast month, he said that sun candles someday will "tame" solar energy "Navigation between stars".

The solar sail will remain in orbit around the Earth and, if everything goes well, will gradually increase its height due to the pressure of solar radiation. But what can these solar candles serve in the future?

According to the NyeThey could be useful for sending robotic missions far, outside of our solar system, as the spacecraft, albeit slower than it would have been equipped with the engine, will gradually accelerate and eventually achieve exceptional speeds.
