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
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
The science of studying celestial bodies and the Universe, astronomy . is one of the most important, since the beginning of time and reveals the secrets of our planet, Solar system and the Universe. The solar system consists of the Sun and many other celestial bodies that revolve around the Sun. It is located in Orion, one of the outer arm of the milky Way galaxy . the sleeves of these zones, which are characterized by a low density of matter.
What is in our Solar system?
In our solar system, you can find the planets mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, and their satellites.
In the beginning, people thought that our planet Earth is in the center of the Universe, and the Sun, the stars revolve around the Earth. Copernicus, born in 1473, was the first person who proved that the Earth together with other planets of our solar system revolve around the Sun. Continue reading
