According to NASASpaceflight.com, Starhopper's static fire ignition is approximately 30 minutes (22:30).

Starhopper has begun to bleed, a sign that propeller loading is advancing rapidly. In theory, this is a strong indicator that the SpaceX prototype is about an hour away from a static fire ignition test planned for Raptor.

Fire crews are on standby in Boca Chica, Texas, where SpaceX's Starhopper is expected to be within hours of completing a complete ignition and static fire test. If all goes well, Starhopper 's July 15 static shooting will be a big step forward to the first unstuck Starship prototype low – fidelity flight, a hovering test that lets you see the craft fly by as far as it can go. at 20 meters from the ground, hold on, and then return to its base for a soft landing.
It looks like the supply has started.

Bumpty Bump for streaming options. No absolute certainty of a static fire tonight, but let's spend a fun evening screaming at sightings such as "Flare Stack!" Ventilate the bottom. Ventilate the top. Ooooh, massive pile of reflections! "? https://t.co/IPDZFaYOSP

Data collected from Starhopper – grouped together in South Texas with thick stainless steel elements and SpaceX Falcon 9 rocket glued parts – will be useful, as it will be the first time SpaceX will pilot a rocket built steel, but the flyby test will be even more significant as a milestone for Raptor itself.
