The latest version of the Falcon 9 rocket that SpaceX was to launch from Florida’s Kennedy Space Center Thursday afternoon is designed to be reused so quickly that it would eventually mimic a commercial airliner, according to SpaceX’s founder Elon Musk.

In a call with reporters before the launch, Elon Musk, SpaceX’s founder, said that if all goes well with the upgraded version of the rocket, the company intends to attempt to fly it twice within 24 hours as soon as next year, a monumental achievement that Musk said “would be a very exciting outcome.”
