SpaceX company announced the second generation of manned "dragon" spacecraft design scheme, the cabin can carry a maximum of 7 people

The US SpaceX company today released its second-generation Dragon ship (Dragon V2), the first manned spacecraft to be launched by a private company that could ship up to 7 astronauts to the International Space Station at a time, according to plans by NASA and SpaceX, and the Dragon 2 is expected to be formally flown to space in 2017.

According to SpaceX co-founder Elon Musk, it can be returned to Earth and "landed on any ground as precisely as a helicopter, and it can be reused quickly." You just need to re-inject the propellant and then you can do it again ... Imagine that if the spacecraft were discarded after each mission, no one could afford the cost of the flight.
