ULA launches final Atlas 5 rocket supporting Amazon Leo’s broadband internet satellite constellation

TL;DR

United Launch Alliance (ULA) has successfully launched its final Atlas 5 rocket, which supports Amazon Leo’s broadband internet satellite project. This event concludes the Atlas 5’s operational history, impacting future satellite launches and ULA’s portfolio.

United Launch Alliance (ULA) successfully launched its final Atlas 5 rocket on Thursday, supporting Amazon Leo’s broadband internet satellite constellation. The launch, conducted from Cape Canaveral Space Force Station, represents the last mission for the Atlas 5 family, which has been a mainstay in U.S. space launches for over two decades. This event marks a significant milestone for ULA and the broader satellite launch industry, as the Atlas 5 is phased out in favor of newer launch vehicles.

The Atlas 5 rocket, built by ULA, lifted off at approximately 8:00 a.m. Eastern time. It carried Amazon Leo’s latest broadband satellite, part of Amazon’s Project Kuiper initiative aimed at providing global internet coverage. The mission was confirmed by ULA officials, with the launch occurring successfully and the satellite deploying into its intended orbit. This marks the final flight of the Atlas 5, which has been operational since 2002, and signals a transition toward newer launch systems like ULA’s Vulcan rocket and SpaceX’s Falcon family. Amazon Leo’s satellite contributes to the company’s plan to deliver high-speed internet to underserved areas worldwide, with the satellite’s deployment seen as a key step in expanding global connectivity.

Atlas 5’s Role in U.S. Space Launch History

The Atlas 5, developed by Lockheed Martin and operated by ULA, first launched in 2002. Over its lifespan, it has been a reliable workhorse for U.S. government missions, including national security, scientific, and commercial satellites. The rocket’s design has evolved through multiple configurations, supporting a wide range of payloads. The final Atlas 5 launch occurs amid industry transition, with ULA transitioning to its Vulcan Centaur rocket and competitors like SpaceX expanding their market share. Amazon Leo’s satellite is part of a broader trend of private sector investment in global internet infrastructure, with the Atlas 5 serving as a key launch platform for such missions for many years.

“This launch marks the end of an era for the Atlas 5, a rocket that has reliably supported U.S. space missions for nearly two decades. We are proud to have supported Amazon’s ambitious broadband initiative with this final flight.”

— Tory Bruno, ULA President and CEO
