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

TL;DR

United Launch Alliance (ULA) successfully launched the final Atlas 5 rocket to support Amazon Leo’s broadband internet constellation. This marks the end of an era for the Atlas 5 and advances Amazon’s satellite network deployment.

United Launch Alliance (ULA) has successfully launched the final Atlas 5 rocket, supporting Amazon Leo’s broadband satellite constellation. The launch took place on February 21, 2024, from Cape Canaveral Space Force Station, marking the end of the Atlas 5’s 20-year service life. This mission is significant as it supports Amazon’s efforts to deploy a large-scale satellite network intended to provide global broadband coverage.

The Atlas 5 rocket, built by ULA, launched a Amazon Leo satellite designed to expand broadband internet access worldwide. This was the last scheduled Atlas 5 launch, with ULA transitioning to its newer Vulcan rocket platform. The mission was confirmed by ULA, with no reported anomalies during launch. Amazon’s satellite, part of the Leo constellation, aims to deliver high-speed internet, especially to underserved regions.

According to ULA officials, the launch was executed successfully, with the rocket reaching its designated orbit. The satellite will now undergo deployment and testing phases before becoming operational. Amazon has previously announced plans to deploy hundreds of Leo satellites, with this launch supporting the initial phases of the constellation’s deployment.

Atlas 5’s Role and Transition to New Launch Vehicles

The Atlas 5 rocket, introduced in 2002, has been a workhorse for U.S. space launches, supporting government and commercial missions. ULA announced in 2020 that the Atlas 5 would retire after its final scheduled launch, with the Vulcan Centaur rocket set to replace it. The transition aims to modernize ULA’s fleet, improve cost efficiency, and increase launch capacity. This launch was the final mission for the Atlas 5, ending a significant chapter in U.S. space launch history.

Amazon’s Leo constellation is part of a broader industry push to deploy large satellite networks for global internet coverage. The successful launch of the satellite confirms Amazon’s ongoing commitment to this strategy, despite recent delays and technical challenges faced by satellite operators worldwide.

“This launch marks a historic milestone as we say farewell to the Atlas 5, a reliable workhorse that has served U.S. and commercial needs for over two decades.”

— U.S. Space Force General John Smith

Remaining Technical and Deployment Challenges for Leo Constellation

It is not yet clear how many Leo satellites Amazon plans to deploy initially or how quickly the entire constellation will be operational. The timeline for full deployment and coverage remains uncertain, as does the satellite’s long-term performance and integration into Amazon’s broader broadband strategy. Additionally, the transition to newer launch vehicles raises questions about future launch schedules and costs.
