CAPE CANAVERAL, Fla. — SpaceX pulled off another launch of supplies to the International Space Station on Saturday, but its revolutionary attempt to land the leftover booster on an ocean barge fared less well.

The company’s billionaire founder Elon Musk said the first-stage of the unmanned Falcon rocket made it to the platform floating a couple hundred miles off Florida’s northeastern coast. But the booster came down too hard and broke apart, he said.

“Close, but no cigar this time,” Musk said via Twitter. He said it bodes well for the future, though.

It was the first time anyone tried anything like this. Musk maintains that recovering and reusing rockets is essential for bringing down launch costs and speeding up operations.

The primary mission for SpaceX was delivering more than 5,000 pounds of supplies ordered up by NASA, including hasty replacements for experiments and equipment lost in the destruction of another company’s cargo ship last fall, as well as extra groceries.
