A SpaceX Falcon 9 rocket launched 40 broadband satellites to orbit for the U.K. company OneWeb on Thursday (March 9) and came back to Earth for a pinpoint touchdown.
The two-stage Falcon 9 lifted off from Cape Canaveral Space Force Station in Florida Thursday at 2:13 p.m. EST (1913 GMT).
The rocket's first stage came back to Earth right on schedule, touching down on a landing pad at Cape Canaveral about 7 minutes and 50 seconds after launch.

It was the 13th launch and landing for this particular booster, according to a SpaceX mission description (opens in new tab). Among those previous flights were SpaceX's two private astronaut missions, Inspiration4 and Ax-1, which launched in September 2021 and April 2022, respectively.
The rocket's upper stage, meanwhile, continued making its way to low Earth orbit (LEO). The OneWeb satellites were deployed in small batches beginning about 59 minutes after liftoff. All 40 had been successfully deployed by T+96 minutes.
OneWeb is building a constellation of more than 600 satellites in LEO, which will provide internet service to customers around the world.
Thursday's mission, known as OneWeb 17, brings the number of satellites in this network to 582, company representatives said in a mission description (opens in new tab). Just one more launch, of another 40 satellites, will finish the constellation's construction, they added.
Most of OneWeb's satellites have launched atop Russian-built Soyuz rockets operated by the French company Arianespace. But Russia's invasion of Ukraine last year ended that arrangement, and OneWeb had to find other rides to orbit.
The company did so in short order, inking deals with SpaceX and NewSpace India Limited (NSIL), the Indian Space Research Organisation's commercial branch. OneWeb has now flown three times with SpaceX (on Falcon 9 rockets) and once with NSIL (on an Indian GSLV Mark III vehicle).
The SpaceX launch contract is interesting, given that Elon Musk's company is building its own broadband megaconstellation in LEO. SpaceX's network, called Starlink, consists of more than 3,700 operational spacecraft and continues to grow.

I also invented entirely re-usable rockets not just the booster. How they work is the booster contains extra liquid fuel and oxidizer plus small solid fuel landing motors. After the second stage separates, the booster continues on to a parking Low Earth Orbit and waits. When the mission is done the upper stages dock back with the booster and all of it lands back on earth making the entire rocket re-usable. Elon does not have either of these. The solid fuel motors are throttled using waste gates that release combustion chamber pressures.
