A passenger spaceship being developed by Richard Branson’s Virgin Galactic company crashed during a test flight on Friday near the Mojave Air and Space Port in California, killing one pilot and seriously injuring the other, officials said. The crash of the suborbital vehicle, undergoing its first powered test flight since January over the Mojave Desert, 95 miles (150 km) north of Los Angeles, came days after another private space company, Orbital Sciences Corp, lost a rocket in an explosion moments after liftoff in Virginia.
