Record Year in Review: Florida saw 109 orbital launches in 2025, an all-time record. Through June 2026, 43 rockets have launched — still surpassing the entire 2021 total of 31 launches.
Final Atlas V 551: ULA's July 2 launch of the Atlas V carrying 29 Amazon Leo satellites marks the last flight of the 551 configuration, the most powerful variant of this historic rocket.
Amazon Leo Constellation Grows: With this 8th operational launch (14th total), approximately 396 Amazon Leo broadband satellites will be in low Earth orbit, inching closer to the company's goal of early commercial service by the end of 2026.
Why This Matters: The competition between Amazon's Leo constellation (formerly Project Kuiper) and SpaceX's Starlink is heating up. With nearly 11,000 Starlink satellites already in orbit, Amazon is racing to deploy roughly 3,200 satellites to offer comparable broadband service.
Historical Context: The Atlas V 551 first flew in 2006 carrying NASA's New Horizons mission to Pluto. After this launch, only six Atlas V rockets remain — all reserved for Boeing's Starliner missions.
United Launch Alliance launched the 110th Atlas V rocket early Thursday morning from Cape Canaveral Space Force Station's Space Launch Complex 41. The rocket, designated AV-114, flew in the 551 configuration — denoting a 5-meter fairing, five solid rocket boosters, and a single-engine Centaur upper stage. It carried 29 Amazon Leo broadband internet satellites weighing approximately 18 tons, tying the record for the heaviest payload ever launched by an Atlas V. Liftoff was scheduled for 12:30 a.m. EDT with an 85% favorable weather forecast.
Why this matters: This launch represents a turning point for ULA. After this mission, the company transitions entirely toward its next-generation Vulcan rocket. The first Vulcan launch carrying Amazon Leo satellites is expected in the third quarter of 2026.
A Falcon 9 rocket will launch 29 Starlink satellites into low-Earth orbit from Launch Complex 40. The launch window opens from 6:36 a.m. to 10:36 a.m. EDT, with a northeast trajectory. No sonic booms are expected.
Another Falcon 9 mission carrying 29 Starlink satellites, launching from Launch Complex 40 between 5:05 a.m. and 9:05 a.m. EDT.
A Falcon 9 rocket will deploy a batch of Globalstar communications satellites into low-Earth orbit. Launch date and window are to be announced.
On August 30, a SpaceX Falcon Heavy rocket is scheduled to launch NASA's Nancy Grace Roman Space Telescope from Pad 39A at Kennedy Space Center. This telescope will have a field of view at least 100 times larger than Hubble's, marking a major milestone for astrophysics. Sonic booms are expected during this launch.
Amazon Leo (formerly Project Kuiper) is the tech giant's answer to SpaceX's Starlink. The constellation aims to consist of roughly 3,200 satellites in low Earth orbit. To date, Amazon has launched satellites using three different rockets — ULA's Atlas V, SpaceX's Falcon 9, and Arianespace's Ariane 6 — with the Atlas V handling 8 of the 14 total missions.
Amazon has also purchased 38 launches on ULA's Vulcan rockets and 27 launches on Blue Origin's New Glenn rockets, though both vehicles are currently grounded amid anomaly investigations following recent mishaps.
On the commercial front, Amazon recently announced a deal with Hitachi Construction Machinery, which will deploy portable Amazon Leo antennas at construction sites in the UK and Germany starting in 2026. This demonstrates the constellation's potential beyond residential internet — enabling machine health reports, real-time maintenance alerts, and field service workflows.
What is the Atlas V 551 configuration?
The 551 designation means the rocket uses a 5-meter payload fairing, five solid rocket boosters attached to the first stage, and a single-engine Centaur upper stage. It is the most powerful variant of the Atlas V family and has flown 22 missions since 2006.
How many Amazon Leo satellites will be in orbit after the July 2 launch?
Approximately 396 operational satellites will be in low Earth orbit. Amazon's goal is to begin early commercial broadband service by the end of 2026.
What happened to Blue Origin's New Glenn launches?
The New Glenn rocket suffered a major explosion during a recent launch attempt, knocking Blue Origin's missions off the Eastern Range manifest for the foreseeable future. The company is working toward a return to flight later this year.
When is NASA's Nancy Grace Roman Space Telescope launching?
It is scheduled for August 30, 2026, aboard a SpaceX Falcon Heavy rocket from Kennedy Space Center's Pad 39A.
How does Amazon Leo compare to Starlink?
Starlink has nearly 11,000 satellites in orbit and is continuously growing. Amazon Leo plans to deploy about 3,200 satellites. While Amazon is far behind in quantity, the company is positioning Leo as a direct competitor for global broadband internet services.
For space enthusiasts: July offers multiple viewing opportunities from Florida's Space Coast, particularly the early-morning Starlink launches on July 5 and July 9. Mark your calendar for the historic Falcon Heavy Roman Space Telescope launch on August 30.
For broadband consumers: Amazon's Leo constellation is progressing rapidly. Early commercial service is expected by late 2026, potentially offering an alternative to Starlink for internet connectivity, especially in rural and remote areas.
For industry watchers: The retirement of the Atlas V 551 configuration marks the end of an era for ULA. Keep an eye on Vulcan's first Amazon Leo mission (Q3 2026) and Blue Origin's return-to-flight timeline for New Glenn.
