The earth is the home of humankind. Can be considered and the Solar system. After all, we already went to the moon, our spacecraft has reached other planets. It would seem that about the area of Land we need to know everything.
Actually mankind for decades trying to unravel such close and such mysterious phenomena. Describe below of the top ten mysteries of the Solar system.
The Oort Cloud. The main issue regarding this site is that whether there is any? This is perhaps the chief mystery of our Solar system. Scientists have suggested the existence of clouds only hypothetically, but this piece of the Universe no one has seen. The theories then formed comets with long orbital period. Scientists can only assume that the Oort cloud is at a distance of 50-100 thousand.e. from the Sun. The bounds of this object lying on the very edge of the Solar system. The billions of bodies are from the cloud is bound by gravity to the Sun. Continue reading
Flight to the Red planet – the most ambitious project of the American space Agency. Meanwhile, he raises a number of issues. Among them – long stay onboard the ship during the flight to Mars that will take at least six months. Note that the diameter of the ship Orion, which NASA astronauts will fly to Mars, comparable to the length of the van.
One of the solutions to the problem of providing astronauts the US more volume on Board. The private rooms, space for physical offices – these and more should ideally be on Board the “Mars” ship. To solve these issues will help manned module connected to the Orion unit. It is assumed that the docking will be performed in space. However, about the appearance and the capabilities of the module it is for certain not known.
But it turned out. what NASA intends to spend on its development 55 million. (some of these funds have already been allocated to developers). In this case a working prototype could be ready in 2018. Then, in 2020-ies, the module will be tested near the moon. And only in 2030-ies something similar will be tested in real conditions during the flight to the Red planet. Note that the flight itself will be (if will be) is not before this time. Continue reading
Comet often appears to us as a star with a huge tail of fire. But few people know that this tail, it becomes only, when approaching the Sun. Because it is a heavenly body, heating the ice particles that make up the comet makes the fire produced gas and dust.
As already mentioned, the comet is a large lump of rocks, mixed with snow. Jokingly astronomers call them “dirty snowballs” because of their similarity. Actually ice, which is part of any comet, it is nothing like the frozen gas. To solve the mystery of the origin of the Solar system, several spacecraft have been sent to these heavenly bodies, to collect samples of the substance from which they are composed. After all, many scientists believe that comets were formed from the matter early, even before the appearance of the Solar system.
Also there is a theory that the Sun is his second, invisible part of man that attracts comets. After they all gather together, their weight overcomes the force of attraction of the Sun and the movement continues. This, of course, all comets burn. Hence the phenomenon of a meteor shower. This theory may explain the total disappearance of all comets occurring once in 100 million years. Continue reading
