Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun
Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.
According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading
April 12, Russia celebrates cosmonautics Day. This holiday was established by the decree of the Presidium of the Supreme Soviet on 9 April 1962 in honor of the world’s first manned flight into space.
April 12, 1961 in earth orbit was launched the world’s first spaceship‑satellite “Vostok” with a man on Board. The launch of the first manned space craft was headed by Sergei Korolev, Anatoly Kirillov, Leonid Voskresenskiy.
Pilot‑cosmonaut of the ship was a Soviet citizen pilot major Yuri Gagarin. The start of the space multistage rocket was successful and after the set speed and separation from the last stage of the carrier rocket, the ship began a free flight on an orbit around the Earth.
After circling the globe, through 108 minutes after launch, was included braking propulsion system and the spacecraft‑the satellite began to descend from orbit to landing. In 10 hours 55 minutes Moscow time the astronaut landed in a given area of arable land in the Volga river near village of Smelovka in the Ternovsky district of the Saratov region. Continue reading
THE SEARCH FOR AND DISCOVERY OF THE NINTH PLANET
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
