SpaceX launches 2 powerful internet satellites, lands rocket on ship at sea (video)

A SpaceX Falcon 9 rocket launched two powerful communications satellites today (July 22), then aced its landing on a ship at sea.

The Falcon 9 lifted off from Florida's Cape Canaveral Space Force Station today at 5:12 p.m. EDT (2112 GMT), carrying SES' O3b mPOWER 9 and 10 satellites toward medium Earth orbit (MEO), about 5,000 miles (8,000 kilometers) above our planet.

That was a day later than originally planned. SpaceX tried to launch the mission Monday (July 21) but aborted the try 11 seconds before liftoff, for reasons that the company did not immediately explain.

The Falcon 9's first stage came back to Earth as planned today roughly 8.5 minutes after launch, touching down on the SpaceX droneship "Just Read the Instructions," which was stationed in the Atlantic Ocean.

According to a SpaceX mission description, it was the sixth launch and landing for this particular booster, which is designated B1090.

If all goes according to plan today, the Falcon 9's upper stage will continue carrying the two mPOWER satellites to MEO, deploying them there across a seven-minute stretch about two hours after liftoff.

Luxembourg-based SES's mPOWER constellation currently consists of eight high-throughput satellites, which reached orbit on four Falcon 9 launches from December 2022 to December 2024.

mPOWER is operational now, providing internet service to customers around the world. But the constellation will continue growing, to a total of 13 satellites. Each is built by Boeing and weighs about 3,750 pounds (1,700 kilograms).

"The remaining three O3b mPOWER satellites are currently being manufactured and are scheduled for launch over the next 12 months," SES representatives wrote in a brief update earlier this month.

Today's launch was the 89th Falcon mission of the year already. SpaceX also has three other liftoffs under its belt this year — test flights of its Starship megarocket, which took place in January, March and May.
