We know this I.e. Alpha Centauri C is also called α Centauri C. The study reaches a significant area There will still be time to take close-up pictures of these exoplanets and send them to Earth. It took about 20 years to reach the Alpha Centauri system using a photonic boat propelled by a laser beam sent from the Earth and towed by a probe weighing a few grams. So the policy is the same as already experienced , Driven by the sun’s rays. Initially it took about 80,000 years to pass a study powered by conventional rocket engines. About 4 Alpha Centauri splits the system three times .Triple and is
Presentation video of the Starshot project. Antennas that emit laser waves generate a network of kilometers, equivalent to the output of a space shuttle. By concentrating their beams and aiming at one or more photonic shields a few meters wide, they emit one pulse per day. Radiation pressure will accelerate the sail, and if the sail weighs less than 10 grams, it will reach a speed of about 20% of the speed of light very quickly. A swarm of such studies will set off in 20 years in the direction of Alpha Centauri. Their number will ensure that one of them arrives safely despite possible shocks by dust particles. © Euronews, YouTube
A photonic sail should not tear or melt
Research into the study and the sail that carries it to the stars has continued, and two papers have recently been published that may have somewhat altered the initial perception of the photonic boat. She has to endure (Kite-craft between planets accelerated by the sun’s radiation) This Japanese Jaxa mission, equivalent to NASA or Launched in 2010 and it was very successful.Laser beams and these should ensure the success of the mission between the stars in the future. Is millions of times more intense than the sun and has already been used for such experiments
However, the photonic veil, which can withstand the pressure of laser photons for 20 years, is three meters long and a thousand times thinner than a sheet.
Authors and researchers of two articles published in The photonic sail needs to be constructed from the sheet of Ultra And disulfide Swells under the breath of light and takes on a shape , Than flat as most previous research has speculated. The structure must be bent, it must be almost deep, it is capable of generating thousands of times more acceleration than it can support without tearing a pressure. Earthly.
In one The same researchers handled the problem For heat generated by a laser beam at least a million times more powerful than the sun. Even a small fraction of the energy scattered in the vessel, if it is absorbed, will heat up to the point of melting.
To avoid this, the sail must actually follow a grid-like structure.Laser photons.
This sail should be made and tested with lasers to verify that the calculations and logics of the researchers are correct.
Astronomical research pays off with this promising object

In the same wayRaises the sails of the boat, a photonic sail is propelled by the light transmitting pressure. Traveling outside the Solar System, which is the suburbs of our beloved planet, will not soon be science fiction, but will be true. How? ‘Or’ What? Thanks to the aerofoil that has enough properties to make this dream come true. From the ISS, such You can reach Mars in 60 days and escape from the solar system …
A type Integrated for the first time in 2012, new Made The back is intertwined. It is one of the lightest known materials, with a density of only 180 grams per cubic meter, approximately 7 times less dense. We breathe (1225 g / m3) Its other notable property is its “darkness”, which means its ability to fully absorb light: one in 1,000 photons is reflected.
On the way to Alpha Centauri
These two properties make it an excellent material for the design of photonic boats: its excellent lightness and its ability to absorb photon energy that accelerates most efficiently when illuminated. . This light may be as light as in the Breakthrough Starshot concept or as sunlight as in this study.
Due to its very low density, a spherical sail with a radius of 5 meters and a thickness of 0.1 mm can carry even 55 grams of payload fast enough to escape from the solar system.
