SpaceX blasted off its Falcon 9 rocket on Saturday, marking its first return to flight since a costly and complicated launchpad explosion in September.
"Liftoff of the Falcon 9," a SpaceX commentator said as the tall white rocket launched from Vandenberg Air Force Base in California at 9:54 am (1754 GMT), carrying a payload of 10 satellites for Iridium, a mobile and data communications company.
The satellites are the first in a series of launches planned to upgrade Iridium's global communications network.
The $3 billion project aims to send 81 satellites to low-Earth orbit in coming months.
Following launch, SpaceX landed the tall portion of the rocket, known as the first stage, on a platform in the Pacific Ocean.
The platform, or droneship, was labeled "Just Read the Instructions."
Cheers erupted at SpaceX mission control in Hawthorne, California, as a live video showed the rocket touch down successfully, and remain upright.
"This is fantastic," a SpaceX spokeswoman said.
