Periodic Comet

Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading

Ninth planet in the Solar system

Scientists: the ninth planet in the Solar system — 500-ton piece of ice

The ninth planet has a mass of 10 Earth masses and is moving strongly forward on a bizarre elliptical orbit around a hot star. …The discoverers of the planet are unable to observe firsthand the ninth element of the Solar system, but scientists using mathematical and computer simulation calculated the trajectory of the most distant planet.

Scientists have shown video of the new ninth planet of our galaxy

Yet due to the insufficient capabilities of optics, it is impossible to see this mysterious object. Astronomers still argue that the chaotic motion of some space objects in the Kuiper belt indicates the presence of “the ninth planet”.

New planet: scientists have uncovered details

“Ninth planet” — so scientists call this mysterious object, which has so far failed to see due to lack of opportunities of modern optics, according to “BBC Ukraine”. Continue reading

NASA and Boeing will create a super-heavy rocket

NASA and Boeing have agreed on joint creation of the carrier rocket heavy-lift Space Launch System (SLS) for manned expeditions beyond low earth orbit and transport cargo. SLS is being developed instead of the carrier rocket Ares V, its first test flight is scheduled for 2017.


National aerospace Agency (NASA ) and the U.S. company Boeing have signed an agreement on the creation of the carrier rocket heavy-lift Space Launch System (SLS) capable to cargo and manned missions beyond low earth orbit. The price of the agreement amounted to $2.8 billion, according to the English portal RT .

According to the developers, who worked on the project for several years, the first version of the rocket will reach 100 meters in length and orbit nearly 22 tons of cargo. Its launch is planned in 2017.

Second, enhanced version of the SLS will have 20 meters long and its capacity will exceed 113 tons. The rocket should put into space manned spacecraft MPCV astronauts on Board, which is projected on the basis of the ship Orion. First flight is expected in 2021. Continue reading
