Since the first flight into space was felt, that the output of the Universe is only open to military and scientists. Silently went planetary exploration, identified to them interesting mineral deposits. Commerce then woke up, to do funny classes for those days - to buy and sell land for settlement on the Moon, Mars and other planets, buy planets of distant galaxies.
But what good have its "6 acres" on the Moon, unless the certificate is on the hands, and "bus" there do not fly? It turned, that private companies is nothing to prevent build their rockets and spaceships. Of course, Quality Control, чтобы они не сыпались на головы землянам – даже у NASA и Роскосмоса случаются такие штуки. 
The first attempts to build a private rocket were made back in the 80s, and he was a pioneer company in Germany OTRAG. planned, that the original design of the rocket will be able to deliver cargo into orbit 180 km. The project has been crushed by political considerations, although the prospects he had.
After ten years of private companies as a burst, and rivet rocket dozens of manufacturers. Finally, it was difficult, If all the calculations for "serious" missiles were in the public domain, which simplified the work of designers? But in this case, the life of a typical private space companies often develop according to the scenario: done, done, launched, broke all, project closed. Because it is expensive, very expensive. It is impossible to account for all errors, that await the spacecraft to cross the ocean of air: here and winds, and the need for rapid stabilization, and have a lot of parameters. Violated at least one, and the missile spun, after which it can only be destroyed from the earth. Many projects have been, but almost all of them were either one-off, either burned or closed.
What can I say, commercial space projects today have become almost the most high technology area. Даже у нас в Украине есть частные аэрокосмические предприятия, например компания Макса Полякова “Firefly Украина”, more on https://daily.rbc.ua/rus/show/ukrainskiy-biznesmen-maks-polyakov-sozdaet-1536247244.html.
Interest cause the company, which failed attempts at flight, and their pilots have earned the title of astronauts. It turned, in the US with this business easier: You do not need to do turn around the planet at an altitude of more than 100 km, enough 'to jump and flop "on the parabola to the height 80 km, and you can already be considered as an astronaut. The company Scaled Composites to their Space ShipOne such flights have turned whole 17 again in 2003-2004 years. Special purpose space shuttle-like vehicle is not haunted - it was originally attributed to the role of the tourist shuttle. After that, all drawings and technology were bought by Virgin Galactic to build SpaceShipTwo. Ship seriously altered by a crew of 8 person, and another for April 2013 , she did not overcome the height 25 km.
That you work - SpaceX! Getting Started in 2002 year, Elon Musk has achieved, which we did not reach his competitors - made rockets class Falcon, Dragon spacecraft. AT 2008 , the rocket reached geosynchronous orbit, and later even supplied to satellites. Developer ambitions were as follows, that he is going to make the rocket returned, without losing a single stage. This not only allows environmentally treat the Earth and Space, but also greatly lower the cost of freight.
So, by the 2020 year, it makes sense to hope, what 1 kg of cargo will cost less 1000 dollars. Dragon spacecraft also did not disappoint the expectations - became a reusable spaceship, capable of carrying a crew 7 person, and is already docked to the ISS is about ten times of the scheduled eighteen. landing problem was solved elegantly - splashdown in the ocean, although the developers have decided to issue and vertical landing, смотрите моменты старта и посадки SpaceX Falcon Heavy.
