United Launch Alliance is loading cryogenic propellants for the Atlas V Amazon Leo 8 mission at Space Launch Complex-41.

PlanCapabilityValue 4.0Jul 2, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: Cryogenic propellant loading operations are progressing smoothly at Space Launch Complex-41 for tonight's Atlas V Amazon Leo 8 mission. Atlas and Centaur propulsion console operators here at ULA's Launch Control Center are performing the steps to fill the rocket with liquid oxygen and liquid hydrogen. We are targeting launch at exactly 12:27:45 a.m. EDT (0427:45 UTC).

Atlas V completed its final mission for Amazon Leo.

PlanValue 3.5Jul 2, 2026ULA's next launch, and likely Amazon's next launch as well, will be LV-01, the first Amazon Leo launch on Vulcan. This will also be the first flight of the VC6L configuration, and the first flight of the 85K "LEO-Optimized" Centaur V. Launch is expected in Late-Q3, in September.

The Atlas V rocket will be fueled with 66,000 gallons of liquid oxygen and liquid hydrogen.

United Launch Alliance’s Atlas V has supported Amazon Leo’s deployment to this point.

RelationshipsPlanValue 2.0Jul 2, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: Last few launches were big for @AmazonLeo - bringing us to 390+ satellites deployed, enough to support continuous service across initial latitudes. Still lots of work ahead – including raising all these new satellites to their assigned altitude – but we’ve completed enough launches for initial service this yr, and future missions just add coverage and capacity. Thanks @ulalaunch Atlas V for getting us to this point. Ready for 40+ sat launches on Vulcan. 🚀 🚀 🚀

Project Kuiper protoflight satellites KUPERSAT-1 and KUPERSAT-2 flew on Atlas V 501.

PlanCapabilityValue 3.5Jul 2, 2026And with that, Atlas V has done its job for Amazon and it's now up to Vulcan. It's been impressive to watch ULA launch these Atlas V's in quick succession, especially the last couple months with sub-1 month turnarounds, and makes me excited for what will be possible with Vulcan.

Atlas V completed its final mission for Amazon Leo.

GeneralPlanValue 3.4Jul 2, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: Deployment confirmed. Atlas V has completed its final mission for Amazon Leo, and we've established contact with all 29 satellites in low Earth orbit. Next up with @ULAlaunch: The first of 38 Leo missions on its new Vulcan rocket, which will carry 40+ satellites per launch and support a higher cadence of Leo missions from SLC-41.

The Atlas V 551 mission will move the rocket to the pad, complete testing, load propellant, and launch the mission during the countdown sequence.

PlanGeneralValue 3.5Jul 1, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: United Launch Alliance has initiated the countdown for launch of our Atlas V 551 rocket to advance the Amazon Leo broadband constellation. Today, we are conducting a continuous roll-and-launch countdown over the next 17 hours that we see Atlas V moved to the pad, all the necessary testing completed, propellant loaded and launching the mission. This is part of ULA's efforts to increase launch day efficiency and maximize launch opportunities while continuing our commitment to Amazon Leo. It increases launch cadence by reducing the amount of time that the rocket spends at the pad. The launch time is 12:24 a.m. EDT (0424 UTC) from Cape Canaveral. http://
