- ceejayoz 2y agoThe study was apparently for the Delta IV. https://x.com/mcrs987/status/1848070131781455911 https://x.com/mcrs987/status/1848070131781455911

- ceejayoz 2y agoI'm pretty sure he's talking about Starship, not Falcon 9. Starship doesn't launch from Vandenberg; neither Starship launch site has seals present. Propellant mass 441,800 lbs (https://en.wikipedia.org/wiki/Delta_IV_Heavy https://en.wikipedia.org/wiki/Delta_IV_Heavy) to 906,000 lbs (https://en.wikipedia.org/wiki/Falcon_Heavy https://en.wikipedia.org/wiki/Falcon_Heavy) in the respective first stages.
- throwawaymaths 2y agofalcon 9 heavy has never launched from vandenburg.
- ceejayoz 2y agoBut it will. https://www.vandenberg.spaceforce.mil/News/Article-Display/Article/4001026/notice-of-intent-to-prepare-an-environmental-impact-statement-for-authorizing-c/ https://www.vandenberg.spaceforce.mil/News/Article-Display/A... (Starship hasn’t, either.)
