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

Watch as SpaceX successfully returns the first stage of its Falcon 9 booster to a landing at Cape Canaveral just minutes after it blasted off.

Launch of a SpaceX Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 5,100 pounds of equipment and supplies bound for the International Space Station was called off Tuesday less than two minutes before liftoff because of apparent problems with the second stage engine steering system.

Singed and blackened from three fiery trips to the edge of space and back, a Falcon 9 rocket returned to Cape Canaveral on Sunday after a mission last that week carried the Israeli Beresheet moon lander into orbit, ready for inspections before attempting a fourth — and likely final — launch this spring.
