Atlas 5 set to lift 29 Amazon Leo satellites from Cape Canaveral

ULA is preparing to launch 29 Amazon Leo satellites on an Atlas 5-551 from Cape Canaveral's SLC-41 in the Amazon Leo 7/LA-07 mission within a 29‑minute window; this is the seventh Leo production batch and the penultimate Atlas 5 mission for Amazon, leaving one Atlas 5 launch remaining after LA-07. Weather is forecast to be challenging with about a 30% chance of acceptable conditions; broader context includes delays to Blue Origin's New Glenn, the Vulcan program, and FCC requirements for the constellation, while Amazon's satellites were at NASA's Kennedy Space Center and not harmed by the New Glenn explosion on May 28.
