The largest planet of the Solar System, the third brightest object night sky (after the moon and Venus). Is gazaille body, hard surface does not. Consists mostly of hydrogen and helium. Due to their size can be observed with the naked eye as a star of the first magnitude, but only for a short time in the morning or in the evening. The average distance from the Sun 778 million km conversion – 314.8 years 11 days.
Jupiter has 16 satellites: IO, Leda, Teba(Phoebe), Carme, ELARA, Ananke, Europe, Metis, Pasiphae, Sinope, hamalia, Ganymede, Lysithea, Amalthea, Callisto, and Andrastea. System his companions like a scaled-down model of the Solar system. The four major satellites (Ganymede, Callisto, IO and Europa) discovered by Galileo and are called the Galilean. Continue reading
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
Actually, I got my hands on a smartphone that fully supports navigation using the Chinese navigation system of the Big dipper). On the market, these smartphones should be out in mid to late 2014, but that’s not it.
I thought about how this system works, who and what drove these satellites into orbit and decided to write a brief overview of the history of Chinese Astronautics. Anyone interested — welcome under kat.
Why does the Chinese space program is called chiconautla? Do not suffer, the people of Thailand and Taiwan is not to blame. Just on the Chinese space sounds like (Taicang), which translated means “Too empty”.
The date of birth of the Chinese space can be considered on 16 November 1957. It is in this day was founded by (China national research Institute on rockets) .
Then, of course, he looked a little different.
