SpaceX launched 24 more satellites for its Starlink network on Saturday (July 25), a day after demonstrating it could do the same on its next-gen rocket.

A Falcon 9 rocket carrying Starlink group 17-51 lifted off at 11:51 a.m. EDT (1521 GMT or 8:51 a.m. PDT local time) on Saturday from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

About an hour later, the 24 broadband internet satellites were deployed into low Earth orbit (LEO), as planned.

The launch marked the eighth flight of the Falcon's 9 first stage (Booster 1100), which touched down on the "Of Course I Still Love You" droneship, stationed in the Pacific Ocean.

The successful launch raised the total number of active Starlink satellites to 10,865, according to satellite tracker Jonathan McDowell. That number had been 20 units higher for about 20 minutes on Friday, when SpaceX conducted a deployment and operations trial during the 13th test flight of its Starship launch vehicle.

The Starship test was planned to be short-lived but was successful in providing data to support NASA's decision to fly Starlink systems on its Artemis III crewed mission to LEO, which is scheduled to fly next year.

Saturday's launch was SpaceX's 87th Falcon 9 mission of the year.

Twenty-four Starlink satellites reached low Earth orbit on Tuesday (July 21), a day later than originally scheduled due to a last-second rocket engine abort.

SpaceX at first tried to launch the broadband internet relay units on a Falcon 9 rocket on Monday morning (July 20), but an unexpected engine cutoff at the point of ignition scrubbed the day's attempt. The company did not provide a reason for the abort.

By Tuesday, whatever the problem was had been addressed and the Falcon 9 was ready to fly. It liftoff off at 10:49 a.m. EDT (1449 GMT; 7:49 a.m. PDT local time) from Space Launch Complex 4 East at Vandenberg Space Force Base in California. About an hour later, after a normal ascent, the new Starlink batch (Group 17-39) were deployed into their intended orbit.

"Deployment of 24 Starlink satellites confirmed," SpaceX posted on social media.

The Falcon 9 rocket's first stage, Booster 1082, completed its 23rd mission by touching down atop the droneship "Of Course I Still Love You" positioned in the Pacific Ocean.

The Starlink network provides worldwide access to the internet, especially to areas where other means of connection are not possible. The megaconstellation also enables in-flight wifi and direct-to-cell services for select providers.

Tuesday's Starlink launch was SpaceX's 85th Falcon 9 launch of the year. SpaceX experienced a similar but unrelated last-second abort on its first attempt at launching its 13th test flight of its Starship megarocket on Thursday (July 16). That flight has now been rescheduled for Thursday (July 23).

SpaceX reached a milestone with its latest Starlink launch, sending the satellites into orbit on its 600th flight of a flight-proven booster.

The sexacentennial launch came on the second of two Falcon 9 missions that lifted off less than eight hours apart overnight from Monday to Tuesday (July 13 to July 14). The first flight, with Starlink batch 15-14, launched at 9:28 p.m. EDT (0128 GMT or 6:28 p.m. PDT local time) from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

The second flight, with Starlink group 10-45, followed at 5:10 a.m. EDT (0910 GMT) from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Both launches successfully deployed their payloads — 27 and 29 Starlink satellites, respectively — into their intended orbits, as confirmed by SpaceX.

Both flights also successfully recovered their Falcon 9 first stage boosters. B1093, launched from Florida, completed its 15th flight. B1080, launched from California, achieved its 28th mission. The record for a single Falcon 9 first stage's re-flight stands at 36 launches.

The addition of 56 more Starlink satellites to SpaceX's megaconstellation brought the total active number of broadband internet relay units to 10,839, according to tracker Jonathan McDowell.

In addition to Tuesday's launch being the 600th launch of a flight-proven Falcon 9 stage, SpaceX now stands at 83 Falcon 9 missions this year to date.

SpaceX added 24 satellites to its Starlink megaconstellation on Sunday (June 21) with a launch from California.

A Falcon 9 rocket lifted off at 12:39 p.m. EDT (1639 GMT or 9:39 a.m. PDT local time) from Space Launch Complex 4 East at Vandenberg Space Force Base. SpaceX confirmed deployment of the Starlink batch (Group 17-28) about an hour after their launch.

The Falcon 9 rocket's first stage (Booster 1063) completed its 33rd launch by landing on the autonomous droneship "Of Course I Still Love You" stationed in the Pacific Ocean. The stage is just two flights shy of the current Falcon 9 reuse record of 35 launches.

The Starlink network now has more than 10,600 active satellites, according to tracker Jonathan McDowell. The service provides worldwide internet access, as well as inflight wifi and direct to cell connections for select providers.

Sunday;s launch was SpaceX's 72nd Falcon 9 mission of the year out of a total history 655 missions.
