The bombardment of comets

Possibly, comets brought water to Earth

To see exactly what is in the comet, it is necessary to analyse its substance with the help of different high sensitive devices, bringing samples to Earth. But aboard a small spacecraft such devices are difficult to place, because the size of the station Stardust 1,7×0,7×0,7 meters – about the same size as the Desk. How to take a sample of matter, flying from the comet’s nucleus at high speed? Space standards Stardust was moving slowly relative to the comet, about one and a half times slower than fly around the Earth artificial satellites. However, even this speed was several times greater than that of the bullet, the station flew over one second 6 km from the Contact of dust particles with the container of solid material at this speed (more than 20 thousand km/h) would have led to their strongest heating and evaporating. The only way to mildly catch and stop these dust particles, turned out to be a trap made of unique material – aerogel, which was established in 1931, but the big distribution has not received.

New space ships of the USA and Russia

New ships Russia: Soyuz TMA-MS, Progress MS, PCA and PTK NP Rus.

New ships USA: Cygnus, Dragon, CST-100, Orion.

Existing ships of Russia: Progress M, Soyuz TMA-M.

Existing ships of the United States: no.

Signus together with Soyuz TMA-M

Soyuz TMA-MC is a Russian multi-seater spacecraft for flight in earth orbit.

New upgraded version of the spacecraft “Soyuz TMA-M”. The update will affect almost every system of manned spacecraft. The first launch is planned no earlier than 2016.

The main points of the program of modernization of the spacecraft:

the energy-conversion efficiency of solar cells, will be enhanced through the use of more efficient Photovoltaic cells;

the reliability of rendezvous and docking of spacecraft with the space station due to the change in engine installation of the mooring and orientation. Continue reading

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
