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.

In the new year period in December 2015 on the horizon we can observe the double-tailed comet Catalina C/2013 US10 Catalina.
Information, data, interpretation of the significance of the comet Catalina.
Astronomical, cosmopolitisme and mythological content of the comet Catalina.
Comet C/2013 US10 Catalina.
Good news for all lovers of the starry sky — comet C/2013 US10 Catalina two weeks ago passed perihelion, the closest approach to the Sun, and now flies back to the depths of space. Until January 17, Catalina will approach closer and closer to the Ground, and in the first weeks of December, the sky in the middle latitudes it reaches the maximum sky brightness. This is a great chance to watch the comet live — even more so that the next time Catalina will be visible only after a few million years. Continue reading
The organizers of the flight of the Russian truck “Progress MS” for the first time ran it with the help of satellite repeater
Several new Russian technology has been rolled out to the launch of a new Russian cargo ship “Progress MS” to the International space station. Apart from the fact that the ship itself and many of its systems have been tested in space flight for the first time, in a new way and passed the session with Earth. This was done through the satellite-retransmitter.
A historic event occurred on Monday, December 21. Launch vehicle (LV) “Soyuz-2.1 a” with the “MS Progress” was launched from pad № 31 Baikonur cosmodrome on 21 December at 11.44 MSK with 2.5 tons of various cargoes for the ISS.
– We used the satellite during the first cycle of flight, – says Deputy head of the scientific and technical centre of space-Rocket Corporation “Energy” Igor BRODSKY . Approximately 10 minutes after separation from the third stage of the rocket the ship made a turn to build orientation on the spacecraft “Luch-5B”, located on the geostationary orbit. Prior to this flight, the communication with the ships was carried out using only ground points, located on the territory of Russia “. Continue reading
