If that first test of the unpiloted SpaceX Falcon 9 rocket and Crew Dragon spacecraft goes well, a second test will fly astronauts Robert Behnken and Douglas Hurley to the International Space Station in June.
The rocket Falcon 9 production for 16 SpaceX mission to the ISS is scheduled from the spaceport at Cape Canaveral in Florida (USA).
The SpaceX Falcon 9 rocket blasted off carrying the Dragon spacecraft at Cape Canaveral on December 5, 2018.
"Appears to be undamaged and is transmitting data".
SpaceX has been successfully landing its rockets back to base since 2015.
The trouble started shortly after Wednesday's afternoon launch, when the hydraulic system on the booster's grid fins failed, Musk tweeted, causing it to start spinning rapidly toward the Atlantic Ocean. This mission is NASA's 16th mission of SpaceX, which is part of a long-term contract to deliver supplies in space.More news: New Zealand beat Pakistan in third Test to win series

"The engines in time stabilized the rotation of the rocket, allowing for a safe landing in the water!"
SpaceX has launched its unmanned Dragon cargo capsule, propelling its payload to the International Space Station (ISS) despite a post-launch failure affecting the first-stage rocket. "Ships en route to rescue Falcon", he wrote.
Ocean platform landings have proven a bit trickier, but SpaceX has managed to stick the landing, whether on land or sea, 32 times in all. After the lift-off, everything went as per the plan including the crucial part where it effectively propelled the cargo-laden Dragon capsule towards the worldwide space station.
The bad food was replaced ahead of Wednesday's launch.
It should arrive at the space station on Saturday.
