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
5 documentaries about space, which is a must-see after “Gravity”.
Of course, no one claims that the recent release with George Clooney and Sandra bullock is a scientific and educational films.

Of course, tours offer only a couple of times a year and extensive training is needed, but in any case should not stop the applicant unreal adventures.
So, let’s go directly on the tour:
Space tourists go to the destination to the manned Soyuz spacecraft. Not to say that you will fly in comfort, but to the very door of the “hotel”. The flight will take approximately 6-7 hours, but the road back is shorter by almost 2 times.
Also there is another way – it is suborbital flights. You climb to a height of about 100 km 5-6 minutes of weightlessness and back to Earth. It’s not as interesting as a few days, for example, on the ISS, but still exciting and also much cheaper. The price hovers around one million rubles. Agree – it is significantly different from full-fledged space flight. Continue reading
