Move around the Sun nine major planets in the following order starting from Sun: mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. All these planets revolve around the Sun in one direction, called direct. Orbits of major planets are ellipses that are very close to circles, and the planes of their orbits inclined to the Ecliptic at a small angle. The mass of all the planets together make up only with 0.0013(3) the mass of the Sun. In addition to these major planets, mainly between Mars and Jupiter, is moving a large number of smaller bodies called minor planets, or asteroids. The number of known small planets as a result of new discoveries is constantly growing and currently there are more than 1600.
Planets of the solar system in size sharply divided into two groups. To the first group belong to relatively small planets closest to the Sun: mercury, Venus, Earth, Mars. This group is often referred to as group Land. To the second group belong the large planets of the solar system. Jupiter, Saturn, Uranus and Neptune. This group is called the group of Jupiter.

Every year the space industry is developing more and more actively penetrating into all spheres of human activity. Satellite TV and mobile communications, navigation and weather forecasts, the creation of unique pharmaceutical products and materials with special properties — all created using different types of spacecraft.
Man, thanks to the space travel, learned a lot about their planet Earth, he had a great opportunity to see her from the side. Currently the mass of satellites moving around the Earth each in its own orbit, provide people an amazing opportunity. Satellites can capture high quality images to explore the planet, to transmit different radio signals, as well as provide quality work for many devices that operate on Earth.
A variety of rocket and space systems to EN.all.biz allow you to perform many important tasks in the industry. With their help, perform the required operation: refueling and technical inspections, management modes of flight and experimentation.
The Earth’s orbit has allowed many of the new to learn more about natural satellite — the moon, and other planets of the Solar system. With the help of satellites and robots we collected various soil samples,and studied the characteristics of gas content of various space objects. Through such studies, scientists were able to propose and test hypotheses about the formation of the planets, Sun and other galaxies. Continue reading

This is the sixteenth report on a project on modeling of human presence on Mars called HI-SEAS.
On Tuesday, the crew of mission HI-SEAS for the first time in four months go outside without protective training suits. On our cheeks sparkle with the wind, the fresh air will fill our lungs, and if the weather is good, sunlight will Shine on our faces. We return back to planet Earth.
But before returning there was one interesting thing. Paradoxically, we in the conversations deviated from the earth and even from Mars. We talked about the fact that you will need for the construction, management and life on a spaceship, which will travel to the nearby stars, and which some generation will change the other, because the flights of this kind will last hundreds of years.
These conversations inspired us primarily the commander of our crew Vermeulen Angelo (Angelo Vermeulen). Angelo from Belgium, he is an artist, biologist and researcher space systems. He firmly believes that the legendary the starship enterprise from “Star trek” was basically wrong. Continue reading
