A trusted orbital analyst says Rocket Lab's latest mystery payload is now cataloged as a BlackSky satellite

Jonathan McDowell reported on X that the BlackSky Global satellite launched on Electron on March 5-6 has now been cataloged in a 467 x 477 kilometer orbit at 42.0 degrees inclination, confirming a successful insertion. That follow-up adds a harder post-launch data point to a mission that Rocket Lab and SpaceNews had initially described as a confidential-customer flight, even though the reporting strongly suggested BlackSky was the likely operator. In practical terms, the mission has moved from a likely attribution story to an on-orbit confirmation story.

This is the kind of small but useful verification update that turns launch speculation into something concrete and searchable.

The next checkpoint is the one BlackSky investors and operators actually care about: image delivery and proof that the new satellite is performing on orbit. But for now, the catalog entry is the cleanest public confirmation that the launch did what it needed to do.
