(CAPE CANAVERAL, Fla.) — NASA’s historic moonshot pad is back in business. A SpaceX Falcon rocket blasted off Sunday morning from Kennedy Space Center’s Launch Complex 39A. It’s carrying a load of supplies for the International Space Station. Astronauts flew to the moon from this very spot nearly a half-century ago. The pad was last used for NASA’s final shuttle mission nearly six years ago. This is SpaceX’s first launch from Florida since a rocket explosion last summer.
