Yeah, I agree, fuck seals. The more we damage marine mammal life with loud sounds the better. If they didn’t want to get killed off in awful ways by our tech toys they should have evolved ear muffs.

      Your link is about the Gulf of Mexico. Vandenberg (https://en.wikipedia.org/wiki/Vandenberg_Space_Force_Base https://en.wikipedia.org/wiki/Vandenberg_Space_Force_Base) is on the Pacific Ocean, where there are most certainly seals and sea lions. https://www.vandenberg.spaceforce.mil/News/Features/Display/Article/1069703/elephant-seals-join-team-v/ https://www.vandenberg.spaceforce.mil/News/Features/Display/... You have the wrong body of water.

        Delta IV heavies also launched from Vandenburg since long before f9 existed, and is considerably louder than falcon 9. was there a need for that study?
        ceejayoz 2y ago
        The study was apparently for the Delta IV. https://x.com/mcrs987/status/1848070131781455911 https://x.com/mcrs987/status/1848070131781455911

        I'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.

        falcon 9 heavy has never launched from vandenburg.

IIRC this study was not about the lethality of Starship, it was about whether the seals were agitated or disturbed by the launch.
