The investor Yuri Milner will invest $ 100 million in the project mission to Alpha Centauri. For this ship to be built that can develop a speed of 160 million km / h. In an interview with RBC Milner told about the details of interstellar project
- Why do you want to build nanokorabl and not manned spaceship, for example?
- When people imagine interstellar travel, it seems they like in "Star Wars": the huge ship flying through some wormhole to the speed of light, in which a lot of interesting things going on. But this topic is pre impassable because such a huge thing it is impossible to accelerate size. Even with those sources of energy, which we do not have.
What is the main problem of interstellar travel - it was not the engine, which would be adequate to the task. People thought on fusion energy, antimatter, there are only three or four options. One of them - a solar sail, the photon. The problem in all of the other options - we simply have no scientific basis. We can not yet even on the ground, use fusion energy until it is impossible, and we have no idea where to take as much antimatter where it is stored, and so on. We are up against the fundamental scientific problems.
With the sail essentially scientific problems was not, there were technical problems: the actual sail and fly spacecraft were always very heavy. And where to get as many photons, it is not clear, and the sun is not enough. The whole subject was in a frozen state, and it was thought that for several hundred years, it was possible not to worry.
- What has changed now?
- The solution of the problem lies in an unexpected direction, namely, let's take a spaceship very small. So small that it will weigh a few grams and one gram. And make it very easy sail. And if this can be done, the problem gets solved fundamentally. And why do it - over the last 15 years there has been progress in the field of microelectronics, which is mainly used for mobile phones and other devices.
