After the shuttle program was shut down in July 2011 following a 30-year run, NASA began outsourcing the logistics of its space missions. Russian Soyuz seats go for up to $82 million apiece. That includes interior life-support systems, autonomous docking capability, an integrated launch escape system, and solar panels built into the spacecraft itself.

"We're going to learn a ton from this mission", said Kathy Lueders, the manager of Nasa's Commercial Crew programme.
