The most important mysteries of the solar system

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

NASA will launch a sailing probe to asteroid

The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.

The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.

However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading

NASA will create a housing module for flight on the Mars

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
