Nanocoral on the laser sail, which is planned to send to alpha Centauri, due to the rotation will deviate from the intended course.
Scientists from the Korean University of science and technology and Harvard University believe that nanocoral on the laser sail, which is planned to send to alpha Centauri, due to the rotation will deviate from the intended course. Corresponding Preprint of the study is available in edition “Tapes.ru”.
According to scientists, due to the rotation of the ship will deviate from the estimated position, upon reaching alpha Centauri, more than 20 radii of the Sun. Accurate estimates depend on the parameters of the interstellar medium and the device ship.
The cause of the rotation of the experts see the clash of nanoparti with charged particles of the interstellar medium, causing the surface of the probe will acquire a non-zero electric charge and, as a consequence, it happens secondary electron emission. The authors believe that electrically charged probe will rotate also, and if it enters the magnetic field, the period of such rotation is estimated at 30-60 minutes.
Experts suggest to consider these effects when designing nanocable on laser sails.
In April 2016, the Russian businessman Yuri Milner and the British theoretical physicist Stephen Hawking has announced the beginning of works on creation and shipment of the satellite to alpha Centauri. The project is actually copies the system DE-STAR (Directed Energy System for Targeting of Asteroids and ExploRation), which in the last several years working at NASA.
