Humanity's first privately-launched, crewed space flight is a few steps from happening. SpaceX gave outsiders a glimpse of the vessel that four NASA astronauts will – if all goes according to plan – ride to orbit next year. "We are not going to fly until we're ready to fly these folks safely," SpaceX President and COO Gwynne Shotwell said. She said the company needs "to demonstrate that this vehicle is capable of taking astronauts up from U.S. soil as often as NASA will allow us to do so."
