In technological terms, the human life is becoming more interesting: XXI century people can tolerate a lot of people couldn’t even conceive of at least two centuries ago. Fifty years have passed since the moment when man first flew into space – and now there is such a thing as space tourism. See with your own eyes on top of our planet is no longer something magical and unrealistic – the question is, what is the cost of space flight.
The man tightly on the Ground
Man and humanity as a community of individuals peculiar passion for travel, for change of place of residence. There are different opinions as to what are the roots of this passion. Romantics say about innate human curiosity, a constant desire to learn something new, to look beyond the horizon.

Flight to Mars, flight to Mars how far is Mars how to fly to Mars, mission duration to Mars
The planet Mars is one of the brightest objects in the night sky. Like a bright red star, it is visible to the naked eye in the night sky. Approximately every two years, Mars and Earth reach their closest point, called “opposition”. At this point, the distance between Mars and Earth is about 55 million kilometers. Almost every two years, the scientists take this opportunity to send to the red planet spacecraft. So how long does it take the spacecraft to reach Mars?
The total time of flight from Earth to Mars varies from 150 to 300 days, depending on the speed of launch, the position of the planets, the route and the amount of fuel on Board.
The first spacecraft to reach Mars was Mariner 4. The device was launched on 28 November 1964. On Mars he arrived on 14 July 1965, where he successfully made a series of 21 Photos. Continue reading
NASA and Boeing have agreed on joint creation of the carrier rocket heavy-lift Space Launch System (SLS) for manned expeditions beyond low earth orbit and transport cargo. SLS is being developed instead of the carrier rocket Ares V, its first test flight is scheduled for 2017.
National aerospace Agency (NASA ) and the U.S. company Boeing have signed an agreement on the creation of the carrier rocket heavy-lift Space Launch System (SLS) capable to cargo and manned missions beyond low earth orbit. The price of the agreement amounted to $2.8 billion, according to the English portal RT .
According to the developers, who worked on the project for several years, the first version of the rocket will reach 100 meters in length and orbit nearly 22 tons of cargo. Its launch is planned in 2017.
Second, enhanced version of the SLS will have 20 meters long and its capacity will exceed 113 tons. The rocket should put into space manned spacecraft MPCV astronauts on Board, which is projected on the basis of the ship Orion. First flight is expected in 2021. Continue reading
