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

The cost of a flight into space

In technological terms, the human life is becoming more interesting: XXI century people can tolerate a lot of people couldn’t even conceive of at least two centuries ago. Fifty years have passed since the moment when man first flew into space – and now there is such a thing as space tourism. See with your own eyes on top of our planet is no longer something magical and unrealistic – the question is, what is the cost of space flight.

The man tightly on the Ground

Man and humanity as a community of individuals peculiar passion for travel, for change of place of residence. There are different opinions as to what are the roots of this passion. Romantics say about innate human curiosity, a constant desire to learn something new, to look beyond the horizon.

Rationalists believe that the desire for constant movement is an echo of the primitive instinct of survival. Primitive man, being the least protected in terms of wildlife and lack of civilization, was required to constantly move to avoid danger and to find new sources of food. Continue reading
