Within 10 minutes of liftoff, the first-stage booster was back at Cape Canaveral Air Force Station, standing upright on the giant X at SpaceX's landing zone. That's where it landed back in June following its first launch. Double sonic booms thundered across the area. At SpaceX headquarters in Hawthorne, California, cheers erupted outside the company's glassed-in Mission Control, where chief executive Elon Musk joined his employees.
The Dragon reaches the space station Sunday. The capsule last visited the 250-mile-high outpost in 2015. This time, the capsule is hauling nearly 5,000 pounds of goods, including 40 mice for a muscle-wasting study, a first-of-its-kind impact sensor for measuring space debris as minuscule as a grain of sand and barley seeds for a germination experiment by Budweiser, already angling to serve the first beer on Mars.
Also onboard were several hundred Star Wars mission patches created by a partnership between Lucasfilm and the Center for the Advancement of Science in Space (the non-profit organization managing the ISS National Lab). Space.com reports that Elon Musk named the Falcon X after the original Millennium Falcon in Star Wars.
