Does some moderator take issue with contributors transcribing the text shown on the ULA video images into ... text?

Amazon expands satellite constellation with successful LA-04 mission [Dec 16]

Quote
United Launch Alliance (ULA) successfully deployed another batch of Amazon Leo satellites into orbit at 3:28 a.m. EST on Tuesday, December 16th. Named LA-04 for Amazon’s fourth launch on a ULA Atlas V rocket, the mission added 27 satellites to the constellation, bringing the total number of Amazon Leo spacecraft launched to date to 180 satellites.

Atlas V deployed the satellites at an altitude of 289 miles (465 kilometers) above Earth, at which point the Amazon Leo team took over command of the mission from our mission operations center in Redmond, Washington. From there, we perform initial satellite health checks and prepare to raise the satellites to their assigned altitude of 392 miles (630 km), where they will be fully commissioned as part of our operational satellite constellation.

LA-04 marks our seventh successful launch this year, and our first as Amazon Leo. These missions have allowed us to deploy enough satellites to begin an enterprise preview for select business and government customers, and we plan to roll out service more broadly as we add coverage and capacity to the network. We’re continuing to increase production, processing, and launch rates as we look ahead to a higher cadence of missions next year, and will have more to share on subsequent missions as they approach.

Amazon Leo

@Amazonleo
Deployment confirmed: 27 more Amazon Leo satellites have been added to our constellation and are operating nominally on orbit. Thanks to @ulalaunch for a fourth successful launch on Atlas V.
