Planned times, published by the launch provider and carried by Launch Library 2 — not measurements. No public feed streams a rocket’s altitude or velocity during ascent, so this site does not show any. Times can move, and a hold moves everything after it.

Projected, not measured. The azimuth and exclusion zones are Flight Club’s published profile for this mission, and the recovery vessel is stationed at those coordinates — but this flight has not happened, and a hold, a re-aim or a scrub changes it. Downrange distance is computed from the pad. No altitude or velocity here: a flight that has already flown can have a real ascent chart, and this one has not flown yet.
