An Atlas V rocket lifted off from Cape Canaveral Space Force Station at 8:53 p.m. EDT on Monday night, April 27, carrying 29 of Amazon's internet satellites into low Earth orbit.
The mission, called Amazon Leo 6 by United Launch Alliance, completed a string of 10 separate deployments that began about 21 minutes after launch and continued for 16 minutes, successfully placing each spacecraft into its intended orbit.
Amazon Leo 6 was the sixth mission ULA has flown to help build Amazon's low Earth orbit broadband network. The Atlas V tied its own payload-weight mark on the flight by lofting 29 satellites — matching the record set earlier this month — and the rocket has now flown six Amazon Leo missions.
The previous Atlas V Amazon Leo flights offer the scale: the first four Atlas V missions together sent 27 broadband satellites skyward, and Amazon Leo 5, which launched on April 4, raised the number of Amazon Leo satellites launched to 29 while setting a new Atlas V heaviest-payload benchmark. The Atlas V heaviest-payload record stands at 18 tons.
The amazon leo rocket launch on April 27 underscores the pace and complexity of assembling a megaconstellation. Deployments began roughly 21 minutes after liftoff and were completed in a 16-minute window, a tight cadence that reflects how these rideshare-style missions stack dozens of satellites into similar orbits in rapid succession.
Amazon Leo — formerly known as Project Kuiper — is being built to rival SpaceX's Starlink service. If the plan is carried through, the Amazon Leo network will eventually include more than 3,200 satellites, and finishing the constellation will require more than 80 launches by a variety of rockets.
That scale is the source of immediate strain. To date, just 10 Amazon Leo liftoffs have occurred: six by Atlas V, three by SpaceX's Falcon 9 and one by Arianespace's Ariane 6. ULA has already scheduled another Amazon Leo mission on an Ariane 6 rocket from French Guiana for early Wednesday morning, April 29, showing Amazon will lean on multiple launch providers to meet its buildout timetable.
The concrete question now is whether that mix of rockets and a handful of launches each month can be sustained long enough to complete a program that needs more than 80 liftoffs. Amazon Leo 6 proves individual missions can hit tight deployment windows and payload marks, but the program still faces the operational test of turning occasional successes into a steady, long-term cadence required to field more than 3,200 satellites.
