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.

Unique comet

Leaving the Oort cloud, the Earth is approaching comet Catalina, consisting of primordial matter.

Comet C/2013 US10 Catalina has completed journey around the Sun and is now approaching Earth. The comet will fly at a distance of 108 million km from the planet. It can be seen with the naked eye or in binoculars 17 January 2016 in the area of the constellation URSA major, reports Global Science .

The comet opened in October 2013 with the help of automated search system, which was developed under the project called the Catalina Sky Survey, providing a view of the sky.

C/2013 US10 is one of the many comets are in the Oort cloud, located at a distance of 50-100 thousand astronomical units.

Experts believe that the cloud is material left from the formation of the entire Solar system.

The first Catalina circled around the Sun took place at the end of November. Now the comet can be observed in the constellation of Virgo, however, this requires special optics. Continue reading

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
