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.</p> <p>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.</p> <p>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.</p> <p>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?</p> <p>Sources:</p> <ul> <li>Spaceflight Now: Starlink 10-39 launch report</li> <li>CelesTrak: Current Supplemental GP Element Sets</li> </ul> data science discuss
