Cancel-and-replace NGA notice.

LHA map from the NGA notice. Splashdown areas some 675km downrange.

Why it takes several days for next launch attempt:

Not that complex. Every cryogenic rocket needs the propellant cold enough and proper density to prevent cavitation. Some vehicles go as far as having recirculation pumps and loops to prevent stratification within the tanks.

Sounds like Relativity are going for the opposite, and deliberately encouraging stratification.

We are GO for prop load, which is getting underway. But, upper-level winds are a potential concern today and we are continuing to monitor. #GLHF
