SpaceX launched one of a kind rocket into space.

A Space Exploration Technologies Corp. rocket successfully blasted 10 commercial satellites into orbit Saturday.

SpaceX, as it is commonly called, is seeking to shore up confidence of commercial and U.S. government customers in its low-cost approach to providing space transportation.Following three postponements in recent weeks for technical or weather reasons, the 230-foot Falcon 9 rocket rose through clear skies and managed to land on a platform in the Pacific Ocean. hat return landing is part of a goal to save money by reusing major components in multiple launches.

Saturday’s blastoff was closely watched by many industry officials because it followed the September explosion of an unmanned Falcon 9 rocket during routine launchpad tests in Florida. About 14 months earlier, in June 2015, a cargo mission destined for the international space station ended in a fireball less than three minutes after blastoff. Those accidents sparked questions about continuing to develop and phase in new booster variants even as the company sought to ramp up launch tempo to reduce a bulging backlog of delayed missions. SpaceX also devised a system to rely on supercooled fuel to assure longer engine burns.

Gwynne Shotwell, the company’s president and chief operating officer, said the 2015 accident served as a catalyst to revamp overall safety practices. “Every engineer in the company is having a buddy check their work” to identify potential shortcomings, she said at the time.
