The fog cleared briefly after this morning's scrub revealing the fairing on a still-icy Falcon 9 B1063!

SpaceX host says yesterday's scrub was due to a faulty ground support equipment valve.

Hosted webcast today.

Fairing halves flying for 5th and 8th times.

Explaining how to launch to orbit, using the famous illustration from Newton's Principia as inspiration.

Final minutes of the countdown.

MECO, stage separation, SEI.

No second stage camera views at request of their customer, SDA.

I believe one can see the second stage in the distance at T+02:49.

Boostback burn allows first stage to return to launch site (RTLS).

Entry burn. 🔥

To me, the cloud tops look like snow-covered rough terrain.
