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
One of the major negative biological factors of outer space, along with gravity, is radiation. But if the situation with the gravity on different bodies in the Solar system (e.g. on the moon or Mars) will be better than the ISS, with radiation, things are more complicated.
On the origin of cosmic radiation is of two types. It consists of galactic cosmic rays (GCR) and heavy positively charged protons emanating from the Sun. These two types of radiation interact with each other. In the period of solar activity, the intensity of galactic rays decreases, and Vice versa. Our planet is protected from solar wind by the magnetic field. In spite of this, some of the charged particles reaches the atmosphere. The result is a phenomenon known as the Aurora Borealis. High-energy GCR almost stopped by the magnetosphere, but they do not reach the Earth’s surface in dangerous quantities due to its dense atmosphere. The orbit of the ISS is above the dense layers of the atmosphere, but inside the radiation belts of the Earth. Because of this, the level of space radiation on the station is much higher than on Earth, but substantially lower than in the open space. Its protective properties of the Earth’s atmosphere pribliziteljny 80-cm layer of lead. Continue reading
Much does it cost to fly in space?
Previously the space was the subject of dreams and the destiny of only the elect, now to experience weightlessness or take a journey to the stars almost everyone can have money. To replace professional the orbit space tourism comes. Those wishing to become astronauts does not scare nor a long period of preflight preparation or high risk, so every year this extreme form of recreation is becoming increasingly popular .
Weightlessness for all
The “budget” option space tourism is a program of suborbital flights, in which the ship goes into orbit, the aircraft goes to higher altitude (about 100 km), which is a while, and then falls down, whereby passengers can enjoy all the delights of weightlessness.
Suborbital flights is the near future of space tourism, says academician of the Russian Academy of cosmonautics named after K. E. Tsiolkovsky Alexander Zheleznyakov. According to him, now several companies (Space Adventures, Another day universe and Virgin Galactic – ed.) are developing aircraft with such a dynamics that one can say that in 2014 will begin to be more or less regular flights.
