Rexy on all its glory 😍 It has been months since I named this beautiful red tailed hawk and finally got the view I wanted. Enjoy one of the best views of a bird I have ever seen, as captured by one of our cameras at McGregor Live 24/7. Thanks for this incredible privilege of seeing you, Rexy ❤️ - @NASASpaceflight

Merlin 1D Sea Level on its pure glory ❤️ This Merlin fired for 177 seconds, it isn't the usual 142 seconds of duration, with a clear view of the deluge starting and engine ignition, where we can see a green flash, thanks to the TEA-TEB, also known as triethylaluminum (TEA) and triethylborane (TEB), the pyrophoric mixture used to ignite it, all the way to the shutdown. Enjoy this 177 seconds of kerolox roar, with a warning for the headphone users 😝 - @NASASpaceflight

I am having a deja vu? I tracked an unusual Raptor 3 leaving through our cameras at McGregor Live this morning. This Raptor, previously SN 76, was first spotted back on December 1 of 2025, now it got its original number covered with an X and got renamed as SN 137, but SN 137 was spotted on Booster 20 in July 6 of 2026 and then on July 20 at McGregor 🤔 Be sure to check our 24/7 cameras for more of these interesting events! - @NASASpaceflight
