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
Space flights cause a failure in the immune system of a person
The results of two studies of NASA, recently published in the journal journal of Interferon & Cytokine Research suggest that spaceflight may cause temporary changes in the immune system of crew members who are long time on Board the International Space Station.
Data obtained at an early stage of one of the experiments showed that the distribution of immune cells in the blood of crew members during the flight remained relatively unchanged. However, they found that some cell functions were significantly reduced, while the activity of another cell type, on the contrary, increased. That is, in a sense, the immune system of crew members, it failed.
If the cell activity is suppressed, the immune system cannot adequately react to threats, which can lead to asymptomatic for the virus. If activity is increased, the immune system becomes too sensitive, which can lead to the development of allergic reactions and persistent rashes, as well as reported some of the crew members.
In another study, scientists analyzed blood plasma, measuring the concentration of cytokines – proteins that regulate the immune system. Continue reading
People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.
Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.
It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.
To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading
