A person is attracted to space. He wants to figure out where it came from, if not from monkeys, and is there intelligent life on other worlds. And don’t always need to look prohibitively far away, if you planet “on all occasions”. Mars became the object of attention long before the exploration of space, and it is popular with filmmakers who want to make fiction.
But it was a fantastic part of the question this film will have problems. The Director was not able to find and catch the right rhythm and the right mood. The trouble is in the details. It begins with the earthly scenes where the astronauts rolled up a party on the occasion of the mission. Then the viewer is immediately thrown on the surface of Mars, where already carried out some work. Even really clear what they’re looking for. In movies about space and traveling through it is always interesting to watch the preparation. As the astronauts enter the ship, as the ship takes off, passes the atmosphere, overcomes a great distance, and were approaching their destination. Well and then — as scientists begin their work, take their first steps in uncharted territory, etc. Continue reading
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.

At the end of last week in Ulyanovsk has started an interesting project Simple science. Its initiator is the teacher of UVAU HA Leonid Podymov.
— The main purpose of my lectures is to educate. I would like to tell Ulyanovsk on the latest and most interesting achievements in modern science into simple language so that it is clear even to the unprepared listener, — says the organizer of the “Simple science”.
Leonid physicist by education, so the project is focused mainly on natural Sciences. In particular, the first lecture was devoted to astronomy — or rather, cosmic distances and scale.
— Many people know that, for example, our Solar system is big. But it is actually an ordinary person is unlikely to adequately represent these scales and distances — simply because it is not something to compare. I tried using a few simple techniques to bring clarity in such comparisons, says the teacher.
So, during the speech he invited the audience to spend with him a few thought experiments.
— Let’s imagine that our planet has shrunk to the size of a standard basketball ball whose radius 12.2 centimeters. If we reduce all other razmery accordance with a given scale, we get the following illustrative figures: the Sun will be a ball with radius 13 meters. Continue reading
