United Launch Alliance (ULA) launched 29 Amazon Leo broadband internet satellites on an Atlas 5 rocket from Cape Canaveral Space Force Station on May 29, 2026, overcoming poor weather forecasts that had initially raised concerns about the mission. The launch, designated Leo Atlas 07 by Amazon and Amazon Leo 7 by ULA, lifted off at 7:53 p.m. EDT from Space Launch Complex 41, shortly after sunset. This was the seventh and final planned mission for Amazon using the Atlas 5 rocket to deploy its Leo constellation, a project aimed at expanding broadband internet coverage across the United States. The rocket followed a north-easterly trajectory after liftoff, marking a significant step in Amazon’s effort to build a low-Earth orbit satellite network. The mission faced significant weather challenges, with the 45th Weather Squadron predicting only a 30% chance of acceptable conditions during the launch window. Weather officers noted that moisture and westerly-to-southwesterly low-level winds would likely bring afternoon showers and thunderstorms to Florida’s east coast, increasing the risk of violations of key weather rules. To accommodate the adverse conditions, the countdown included two planned 30-minute holds, with the second hold at T-minus four minutes extended to allow teams to navigate through a period of unacceptable weather. The successful launch came after a delayed countdown that began at 12:13:30 p.m. EDT on May 29, with fueling operations paused during the first hold before resuming later in the day. The mission was the penultimate Atlas 5 flight for Amazon’s Leo project, with future satellites expected to be launched on different rocket platforms. The launch was observed by local residents and space enthusiasts, who gathered along the Space Coast to witness the event under clear skies shortly after liftoff. ULA’s ability to execute the mission despite the challenging forecast highlighted the resilience of the space industry in Brevard County, where launches are frequently impacted by unpredictable weather patterns.
