Borislav Of Slavoljub

13 March 1783, William Herschel discovered the planet Uranus. This immediately increased the size of the Solar System twice. According to the observations of the planet was determined by its orbit and the theory of the motion of Uranus. However, the observed motion of Uranus differed systematically from the predicted. This discrepancy has allowed John Adams and Urbain the Verrier theoretically predict the existence of the eighth planet – Neptune. open by Johann Galle on 23 September 1846. The discovery of Neptune was a triumph for the theory of universal gravitation of Newton.

Taking into account the influence of Neptune on Uranus was possible to reduce the discrepancies between the theoretical and the observed motion of Uranus dozens of times, but full precision was not achieved. In 1848 the American astronomer B. pierce suggested the existence of a ninth planet. In 1874 S. great effect constructed a new theory of the motion of Uranus, taking into account perturbations from Jupiter, Saturn and Neptune. It also presupposes the existence of a transneptunian planet. Continue reading

Flight to Mars! Fiction?

Looks like little man one planet. So it tends to absorb the nearby. Even if she is away from us the distance that the average inhabitant of the Earth and can not imagine. Wanting to get to Mars abound. And even if there’s no air, and the question of the existence of water is quite ghostly… And even if back to Earth, to return people never will be… but why go to the lifeless Red planet, you ask?

When first heard information about sending to Mars normal inhabitants of our planet, it looked nothing more than an April fool’s joke. And then announced that in 2023 really planned flight on this planet. But only one way.

They say that from those who received about 10 thousand applications. Selected 1058 people, including 52 Russians. These people are willing to volunteer a hitherto unknown expedition, but will fly only four. Call them the lucky ones do not dare. These people are directed by the interest and the strongest desire for change, although mission to Mars is too expensive, too bold and too risky venture. Continue reading
