L-3 UPDATE: Everything continues to progress towards the ULA Atlas V launch carrying the Protoflight mission for Amazon’s Project Kuiper. The mission is planned to lift off on Friday, October 6 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The launch window opens at 2 p.m. EDT. Today’s forecast shows an 80 percent chance of favorable weather conditions for launch.
The forecast from the Space Force’s Space Launch Delta 45 weather squadron and Launch Weather Officer Melody Lovin for Friday’s launch of Atlas V indicates an 80 percent chance of acceptable conditions.
“By Friday, the ridge across the eastern Continental U.S. weakens and shifts into the north Atlantic, loosening the pressure gradient and thereby our winds and moisture levels in time for launch day. Showers and thunderstorms cannot be completely ruled out but should be on the isolated side Friday afternoon,” the weather team says.
The launch time forecast for 2:00 p.m. EDT (1800 UTC) includes scattered clouds, possible isolated showers, good visibility, northerly winds 8 to 12 knots and a temperature near 81 degrees F.
If the launch moves to the backup opportunity on Saturday for some reason, there is an 85 percent chance of meeting the weather rules with similar but drier conditions expected.
Launch Forecast Summary:
Overall probability of violating weather constraints: 20%
Primary concerns: Cumulus Cloud Rule
Overall probability of violating weather constraints for 24-hour delay: 15%
Primary concern: Cumulus Cloud Rule
Standing nearly 20 stories tall, the Atlas V 501 rocket will deliver its payload into low Earth orbit as part of the Project Kuiper Protoflight mission for Amazon. The prototypes of the final Kuiper satellite design will allow Amazon to test its technology in space before beginning full-scale production launches next year.
The Protoflight launch is also the first mission in a broader partnership between ULA and Amazon to help deploy Project Kuiper’s low Earth orbit (LEO) satellite constellation. Amazon will use nine launches of the Atlas V rocket and 38 launches of Vulcan Centaur to deploy its satellites. The prototype mission gives ULA and Amazon practical experience working together ahead of full-scale launches, including processing procedures, payload integration and mission management.
Atlas V will place two spacecraft — Kuipersat-1 and Kuipersat-2 — in 311-mile (500-km) orbits with an inclination of 30 degrees. Centaur uses a single burn to place the satellites into their desired perch and deploys them approximately 18 minutes after liftoff, at which point Amazon will assume control of the satellites and proceed with testing.
The Protoflight mission will add real-world data from space to Amazon’s results from its extensive lab testing, fieldwork and simulation, and help Amazon finalize plans ahead of a full-scale satellite deployment beginning in 2024.

Launch status update
(Cape Canaveral Space Force Station, Fla., Sept. 28, 2023) – The launch of a United Launch Alliance (ULA) Atlas V 501 rocket carrying Amazon’s Project Kuiper Protoflight mission is planned for Fri., Oct. 6 from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida. The launch window opens at 2 p.m. EDT.
Protoflight: Atlas V stacked ahead of first Kuiper launch
United Launch Alliance (ULA) uses heavy-duty cranes, teamwork and a lot of coordination to assemble our massive rockets before they head into space. That art of rocket stacking is both time-tested and an obligation to some passengers who require vertical integration of their payloads.
This week, engineers and technicians at Cape Canaveral Space Force Station, Florida, completed the initial buildup of the Atlas V 501 rocket that will launch prototypes of the Project Kuiper broadband system for Amazon.
The satellites will add real-world data from space to results from Amazon’s extensive lab testing, fieldwork, and simulation. This Protoflight mission also helps Amazon finalize design, deployment and operational plans ahead of a full-scale deployment beginning in 2024.
Preparations for this first launch began Sept. 16 with the Launch Vehicle on Stand (LVOS) milestone.
Before sunrise, the move crew arrived at the Advanced Spaceflight Operations Center (ASOC) to configure the Atlas V first stage for its delivery to the Vertical Integration Facility (VIF), located about four miles up the road.
