That’s 27 hours from now.
SpaceX is targeting Saturday, July 27 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Liftoff is targeted for 12:21 a.m. ET, with backup opportunities available until 4:21 a.m. ET.
During the first burn of Falcon 9’s second stage engine, a liquid oxygen leak developed within the insulation around the upper stage engine. The cause of the leak was identified as a crack in a sense line for a pressure sensor attached to the vehicle’s oxygen system. This line cracked due to fatigue caused by high loading from engine vibration and looseness in the clamp that normally constrains the line.
I almost wonder why it was still there if it wasn’t really used. It would be really interesting to learn more about how they tracked this down so specifically.
That does seem to run counter to SpaceX/Elon’s ethos. Maybe it was just a case of “if it ain’t broke, don’t fix it”? (Until it did break, of course…)
