Vandenberg SFB Launch Alert
"Due to unforeseen circumstances, the launch attempt for a SpaceX Falcon 9 rocket carrying the USSF-259 mission -- originally planned for Sept. 15, 2026 -- will instead proceed on its planned backup day: Wednesday, Sept. 16, 2026, between 6:00 p.m. – 10:00 p.m. PT from Space Launch Complex 4 East (SLC-4).
A minimal possibility exists that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear a sonic boom during the launch. Depending on weather and location, this event may sound like an abrupt crack of thunder according to prediction models."

💁🏻♀️ TIL: 🏰⚙️ #Aerospace engineer Tom Stanton built a backyard #trebuchet powerful enough to launch a projectile past the speed of #sound.
He redesigned the ancient siege weapon with a 3:1 pulley system and a longer sling that revolved multiple times to gain #momentum. After extensive trial and error, his release cracked the whip of a #sonicboom at 1,249 km/h (776 mph), just clearing the 1,234 km/h (767 mph) barrier.

Seeking Quieter Supersonic Flight
Supersonic flight over the U.S. has been banned by all non-military aircraft for more than fifty years. The ban gained momentum in the 1960s after test programs over St. Louis and Oklahoma provoked public outcry. But NASA’s X-59 aircraft is working to lift the ban by softening the sonic booms that encouraged the ban in the first place. Although it hasn’t been tested at supersonic speeds yet, pilots are putting the sharp and skinny X-59 through its paces, slowly widening the flight envelope.

In the video above, NASA shares footage of some of the recent test flights, including various maneuvers like phugoids, banking rolls, flutter, and landing gear tests. Pay close attention to the pilot’s view and the radio chatter, and you’ll hear that they’re hovering around Mach 0.98 in some cases–just underneath the point of generating a shock wave around the aircraft. It will be neat to see what happens when they finally do go supersonic. Will it be as quiet as promised? (Video credit: NASA; image credit: NASA/L. Losey; see also NASA; via Gizmodo)
