The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.
The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.
However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
But only 25 people winning perfume brand AXE
International perfumery and hygiene brand “AKS” (AXE) announced the launch of a global campaign, during which there will be a selection of candidates for space flight on the ship the American company Space Expedition Corporation (Space XC), the Agency reports ITAR-TASS. For 25 people, selected to participate in the international space program launched AXE in conjunction with Space XC, which since 2008, specializes in projects related to space tourism, space flight, scheduled for the first quarter of 2014, will be completely free.
To date, the last (as the astronauts, “extreme”) is a space tourist canadian billionaire and founder of world famous Cirque du Soleil, guy laliberté, who in the autumn of 2009 on the Russian ship “the Union” took part in the expedition to the International space station (ISS). Ticket to space “round-trip” cost him $ 35 million. Since the first successful flight of a tourist wishing to see the space is steadily increasing. Grows and the cost of this tour: starting in 2001, when in outer space, visited the first “Amateur” – the American businessman Dennis Tito, the fare has doubled – from 20 to 40 million dollars.

Solar system — the planetary system that includes a Central star — the Sun — and all the natural space objects orbiting the Sun. It was formed by gravitational contraction of the dust cloud around is 4.57 billion years ago. Note: the sun is not a planet.

Pluto is the decision of the MAC (international Astronomical Union) no longer applies to the planets of the Solar system, and is a dwarf planet and even inferior in diameter another dwarf planet Eris. Designation 134340 Pluto.
Scientists have put forward many versions of the origin of our Solar system. In the forties of the last century Otto Schmidt put forward the hypothesis that the Solar system arose because the cold dust cloud attracted by the Sun. Over time the cloud formed the foundations for future planets. In modern science it is theory that Schmidt is the principal. Continue reading
