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.

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

History of Astronautics – 098
The history of the space a number of times when on the road to further human exploration of outer space rose up high and seemingly insurmountable barriers. In 1961 the transition to weightlessness caused in perfectly healthy astronaut a painful condition similar to motion sickness. In 1966, after a three-week flight on the satellite “Cosmos-110” slightly alive returned to Earth two dogs. In 1970 it became clear that the meeting with Earth after 18-day stay in weightlessness is very difficult for humans. So there was a barrier of reparations, and the possibility of longer flights required further justification. In 1978, after a three-month flight is in the blood of an astronaut found atypical forms of erythrocytes, which suggests the appearance of weightlessness in a new generation of abnormal formed elements. In recent years, in connection with the implementation of the 7-8 series record-month flight appeared ideas about qualitatively new changes in the condition of the body in the postflight period, although not everyone agrees specialists.
