Spaceflight Now covered Starlink 10-39 here. Reposting this because the interesting part is not only the launch image. Starlink 10-39 moved from a last-minute scrub on August 20 to a successful August 21 launch from SLC-40 at Cape Canaveral. The mission carried 29 Starlink satellites toward low Earth orbit, and Falcon 9 booster B1078 landed after its 30th flight. That is already a useful launch-cadence story. The next layer is the data trail after deployment. CelesTrak now lists Starlink G10-39 post-deployment supplemental GP data, derived from a SpaceX-provided state vector. For observers, that is where the story changes from rocket trajectory to TLE/SGP4 freshness, orbital pass timing, and ground-station geometry. A launch photo captures one dramatic moment. Satellite tracking begins when the new objects become predictable enough to follow from a real place on Earth. Which signal do you trust first after a deployment: the operator update, a public catalog entry, a fresh element set, or a confirmed visual pass?

"The expansion of SpaceX's Starlink network of internet relay satellites continued Monday with a Memorial Day launch from Cape Canaveral Space Force Station," reports Spaceflight Now. The mission added another 29 Starlink satellites to more than 10,000 already in low Earth orbit: This was SpaceX's 60th orbital flight of the year, consisting of 59 Falcon 9 rockets and one Falcon Heavy rocket... Nearly 8.5 minutes after liftoff, [Falcon 9 first stage] B1078 landed on the drone ship, 'A Shortfall of Gravitas,' positioned in the Atlantic Ocean off the coast of South Carolina. This was the 151st landing for this vessel and the 614th booster landing to date for SpaceX. Meanwhile, the second stage shut down eight minutes and 39 seconds into flight and entered a coast phase, before short second burn at T+52 minutes. The stack of Starlink satellites deployed 61 minutes and 26 seconds after launch. On X.com SpaceX shared footage of the booster rocket landing, and a longer video showing Starship's 12th test flight Friday. Read more of this story at Slashdot.
