Cape Canaveral: SpaceX launched a newer, bigger version of its Dragon supply ship to the International Space Station on Sunday, marking the first time the company has two capsules in orbit at the same time.
With NASA's commercial crew program officially underway, SpaceX expects to always have at least one Dragon capsule at the space station.
SpaceX's Falcon 9 rocket blasted off with the latest Dragon from NASA's Kennedy Space Center, where coronavirus precautions kept staff to a minimum. The first-stage booster — making its fourth flight — landed on an ocean platform several minutes after the late-morning liftoff. It was first used back in May for the first astronaut launch by Elon Musk's company.

The 6,400-pound (2,900-kilogram) shipment includes billions of microbes and crushed asteroid samples for a biomining study, a new medical device to provide rapid blood test results for astronauts in space, and a privately owned and operated chamber to move experiments as big as refrigerators outside the orbiting lab. Forty mice also are flying for bone and eye studies, two areas of weaknesses for astronauts during long space stays.
