Rockets transit the ozone layer (stratosphere ~15-35 km) in seconds per launch. Exhaust effects depend on propellant. Solid rockets release chlorine & alumina that deplete ozone. Falcon 9 (kerosene) adds black carbon. Starship's methalox (methane + LOX) mainly produces water vapor & CO2—far less ozone-depleting than older tech, though water can indirectly affect it slightly. At today's ~200-300 global launches/year, impact is tiny. Studies project that 2,000+/year could thin ozone ~0.3% globally (up to 4% seasonally over Antarctica), slowing its recovery from CFCs. Reentries add NOx too. SpaceX's multi-site plan spreads this out, but growth needs monitoring.

SPACEX: A realtor named Jim Keaty of Keaty Real Estate published a rumor of possible SpaceX land acquisition in Louisiana. It states SpaceX may have acquired or is acquiring 136k acres (212 sq miles) of marshland south of Highway 82 towards the Gulf of America in Pecan Island and Freshwater City in Vermilion Parish of the Acadiana region. At the Southeast corner of the land near the Freshwater City boat launch is a plot ready to be converted for port operations and direct access to the Intercoastal Canal and the Gulf of America. Pecan Island is halfway between Boca Chica and Cape Canaveral, and has easy access to Cheniere LNG and Golden Pass LNG; both on the either side of the Louisiana and Texas border at Sabine Pass. This has not been confirmed by SpaceX of Elon. More SpaceX news in the ELON CHRON below!

Last week, the United States refused to participate in the UN’s review of the Global Compact on Migration. The United States objects to the Global Compact on Migration and UN efforts to facilitate replacement migration to the United States and our Western allies.
