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.

100 year spaceship

Humanity seems to have stayed in their home Solar system

In Houston there was a scientific conference on the most ambitious project of the century.

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. And also sent a robot to Mars, which only publishes Pictures in Instagram and writes in Twitter. The main task of space exploration in the long term should be the creation of colonies, which can live people. Continue reading

Parade of planets

Star line-up. As you know, these days several planets in the solar system lined up in one line. This so-called parade of planets. In Irkutsk cosmic phenomenon, of course, interested professionals and Amateurs to observe the Universe.

Fans of star observations go in pursuit of planets in the early morning. Every minute counts. Dawn is inexorably approaching. Even a small glow can ruin the expedition. In the suburbs of Irkutsk the best place for astronomical observations — the village of Maksimovschina. There is a good elevation away from the city. At five o’clock in the sky appears the first star of the big parade of planets. Despite the early hour and freezing temperatures, people came here by families with young children.

— Parade of planets happens once in a lifetime. At least see the time. Star-gazing, says participant observations Dmitry Bakers.

Organizes the monitoring of the Irkutsk planetarium. Brought two powerful telescope. With their help, you can enjoy a stunning view of space in all its glory. Thanks frosty air clearer picture. Continue reading
