Photos: More shots of Saturday’s Delta 4-Heavy rocket Launch

SpaceX, the upstart rocket company that has shaken up the launch industry with low-cost reusable boosters and ambitious long-range plans to carry people to Mars and beyond, plans to reduce its workforce by about 10 percent, company sources said late Friday.

SpaceX fired three Raptor engines on a prototype of the company’s Starship vehicle Tuesday, accomplishing another milestone on the road toward testing of the methane-fueled rocket at higher altitudes.

Orbiting the world in seclusion for the past year, the Air Force’s mysterious X-37B spaceplane marks the anniversary of its launch today.
