Q&A with Elon Musk, SpaceX’s founder and CEO

Three space station crew members packed up for a fiery return to Earth Thursday, wrapping up a nearly 200-day mission that was extended one month at the last minute because of a Russian rocket failure in April that threw a wrench into the lab’s crew rotation schedule.

Boeing’s Starliner capsule, carrying an instrumented astronaut test dummy nicknamed “Rosie,” is on track for launch Friday on an unpiloted test flight to the International Space Station, mission managers said Tuesday. The flight is a major milestone in NASA’s push to resume launching U.S. crews from American soil.

Chinese officials said the Chang’e 5 mission finished drilling and scooping samples from a lunar lava plain late Wednesday, hours before the spacecraft’s robotic ascender was due to take off from the moon to begin the trip back to Earth.
