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?
