New | Billionaire Elon Musk unveils Dragon V2, destination the International Space Station

Billionaire Elon Musk has taken the wraps off a spacecraft designed to ferry up to seven astronauts to the International Space Station.
The unveiling of the cone-headed craft dubbed Dragon V2 took place at the Southern California headquarters of Musk’s company, SpaceX.
Musk calls the new spacecraft a big leap forward in technology.
SpaceX is one of several private companies competing to build “space taxis” for Nasa to replace the retired space shuttle fleet. It previously flew four cargo missions to the space station, delivering food and supplies.
Since the shuttle fleet retired in 2011, Nasa has depended on Russian rockets to transport astronauts to orbit and back, paying nearly US$71 million a seat.
In the latest mission, a Russian Soyuz-FG rocket booster lifted a space ship carrying a new crew to the International Space Station from the Russian-leased Baikonur cosmodrome in Kazakhstan on Thursday.
