It is now solved a question of principle: who will be the host space for the next two decades. Half a century, when humanity is poked in the Earth’s vicinity, still not fully understanding why (except that to get ahead of a competitor), has ended. And money in space dumped a lot. The project “Apollo” with six successful expeditions to the moon cost the us Treasury $ 25 billion (in prices of the 70-ies of XX century). And each launch of the Shuttle – under $ 500 million.
The Soviet Union was worth 2.5 billion rubles was never carried out lunar program (and it is in those years when a good wage was considered to be 90 rubles per month). More than 16 billion rubles were thrown into the system “Energy – Buran” Soviet Shuttle flew only once.
Yeah, from the projects was giving. All of these filters, Velcro and scanners, developed for the space and will be useful on Earth… But now we are talking about strategy.
ISS – the day before yesterday
The same strategy that the space powers (Russia and the USA joined China. India. Japan and the EU ) now consider the money very well and meticulously thought through perspectives. Continue reading
The origin of the solar system
The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .
Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.
Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.
The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available. Continue reading
Comet Churyumov-Gerasimenko are two comets stuck together
The researchers of the mission “Rosetta” said the comet 67/P Churyumov-Gerasimenko acquired its form as a result of collision at a low speed of two different comets in the early development of the Solar system.
A team of researchers under the leadership of astrophysics Massironi Matteo (Matteo Massironi) from the University of Padova (Italy) look at the Photos of the comet 67P/Churyumov-Gerasimenko, taken in high resolution in the period between 6 August 2014 and 17 March 2015, it Became evident that the comet was formed as a result of collision of two different bodies, flying at low speed. The results of the ESA study says .
Recall, the first images of the comet from close range, the probe “Rosetta” in July 2014 showed that the object consists of two “blocks” of different sizes. and resembles the shape of a rubber duck. Scientists examined two hypotheses: the first is that the cosmic body had acquired such an unusual form as a result of a collision between two comets, and another stated that the “neck” of the comet formed in the process of natural erosion of rocks that make up the object. Now, however, the researchers got convincing evidence in favor of the first. Continue reading
