Praise and congratulations for SpaceX poured in on Twitter.
"Congratulations on another historic launch," the US space agency NASA wrote on Twitter.
"Congrats, SpaceX," said the Defense Advances Research Projects agency (DARPA).
"DARPA facilitated the first SpaceX launch, and now commercial space is coming into its own."
As for the cost of Thursday's launch, Martin Halliwell, chief technology officer at SES, has declined to say publicly the exact amount.
However, he dismissed "naysayers" this week and stressed the historic nature of the launch on what he has described as a "flight-proven" rocket.
"People said we were taking a huge risk. I always said, 'We're not.'" he told reporters after Thursday's launch.
"We had access to information that gave us confidence," he said, adding he was "hugely excited" that SpaceX was opening "the door to a whole new era of spaceflight."
Musk said the booster that flew Thursday underwent extensive refurbishment prior to launching again, and that it will be donated to NASA to put on display at Cape Canaveral.
The SES-10 satellite was sent to a geostationary transfer orbit, flying as high as 22,000 miles (35,000 kilometers) above Earth.
The satellite aims to expand television, internet, and mobile connections across Latin America.
SES confirmed that the launch had successfully deployed its satellite, and congratulated SpaceX on sticking the landing of the rocket.
