Video: Change of command aboard International Space Station

Soprano and would-be space tourist Sarah Brightman, who was in training for a flight to the International Space Station this fall aboard a Russian Soyuz ferry craft, will not be chasing her dream aloft after all.

Five-and-a-half years ago, SpaceX founder Elon Musk revealed SpaceX’s Crew Dragon spacecraft, a sleek-looking human-rated spaceship with 3D-printed engines, a roomy stylized interior and touchscreen controls. Now SpaceX’s first ship to ferry astronauts — with numerous design changes introduced since 2014 — is about to leave the company’s factory for final testing before launching early next year.
