Ever since then, when the first man left the Earth (and more importantly, successfully got back there) managed a space ship (if someone does not know, this was in 1961), people around the world believe in his imminent future happy in all the visible universe long predicted by science fiction writers: “Yes, with the current rate of technological progress here is just a little magician, the scientists, and we instead of Turkey and Egypt for the weekend to fly to Mars and Saturn!”. And still have been right. Almost.
Of course, before the mass of schoolchildren on tours of the milky way matter has not yet reached, but a single much well-off citizens with great pleasure leave the limits of the Earth, and then talk about how they are there was interesting. God willing, someday we all be vouchsafed, therefore, examine the issue more closely.
Who? Where? How much?
If you have lying around in the cupboard a couple of tens of millions of dollars, then you are in principle nothing to worry about — today can call “Roscosmos” or Space Adventures and sign up for space trips — or rather, for a flight on the Russian spaceship “Soyuz” to the International space station (ISS).

Solar system. The stars and the sources of their energy. Galaxy
The solar system is called the totality of the heavenly bodies moving around the Sun, which is a dynamic centre of this system. The solar system consists of the Sun and planetary systems, including all the natural space objects that revolve around the Sun. Turn around the Sun, 8 major planets with their satellites and rings: mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune. They are divided into terrestrial planets similar to Earth, and giant planets similar to Jupiter. These groups are very different in their physical characteristics. To natural space objects in the solar system include dwarf planets and their satellites, and small bodies: asteroids, meteors and meteorites, comets, cosmic dust. Between the orbits of Mars and Jupiter lies the asteroid belt.
The age of the Solar system approximately 4.6 billion years.
The main features of the Solar system .
The planets move around the Sun in orbits close to circular ones. Comets also move in very elongated orbits, when moving near the Sun, the comet forms a tail.
The orbits of all planets lie nearly in the plane of the equator of the Sun. Continue reading
Most American space programs in recent years have been privatized, and now, the sometimes slow bureaucracy, making stupid things like launching the Shuttle Challenger in very cold weather, when the sealing rings holders solid propellant booster unflexible, corporations aim to make a lot of money.
Last week’s rocket explosion Antares (Tuesday) and “space Spike 2” by “Virgin Galactic” (on Friday) were disasters and, considering the death of one pilot “space Spike” and serious injury of the second, tragedies.
The role of greed here?
Bruce Gagnon, coordinator of the “Global network against the militarisation and nuclear power in space,” said:
“With the privatization of space launch services, the pressure to “cut corners” and save money will be enormous. The idea of launching ships with gullible tourists on Board ships, developed primarily for profit, and least for security – it is scary.” Continue reading
