The booster, meanwhile, streaked to a smooth landing on a recovery ship just offshore.
The Dragon capsule carrying supplies for the astronauts on board the station, along with a host of experiments, is scheduled to reach its docking location on Monday.
After a rare power issue discovered at the last minute on the Dragon cargo capsule a few days ago while preparing to launch, the take-off was delayed until Saturday, May 4th. The Dragon capsule has been talked about in the community of spaceflight fans for quite a while now which means that it is repurposed in this case might raise some eyebrows.
SpaceX launched a load of supplies to the International Space Station on Saturday following a pair of unusual power delays.
Canadian astronaut David Saint-Jacques used the station's big robot arm - also made in Canada - to capture the Dragon approximately 250 miles (400 kilometres) above the North Atlantic Ocean.
With the Dragon safely in hand, flight controllers at the Johnson Space Center in Houston planned to take over, operating the Canadian-built space crane by remote control to pull the Dragon in for berthing at the Earth-facing port of the station's forward Harmony module.
It was SpaceX's 17th delivery to the International Space Station since it started in 2012. Both problems were solved quickly. This was the first time ever a launch operation was stopped because of rocket-landing matter.

The booster should have been stationed at Cape Canaveral Air Force in Florida, but SpaceX is still in the process of cleaning up after the April 20 incident that blew up an empty crew Dragon capsule. NASA has given SpaceX a $2.6 billion contract for building the Crew Dragon capsule that NASA was planning to use for returning human space flight back to U.S. soil.
Its crew includes six astronauts: three Americans, a Canadian, a Russian and one from Turkmenistan.
