Atlas RP-1 loaded
The joint launch team is wrapping up the planned activities for rollout day and the Atlas V rocket is being powered down for the night. The next event will be starting the launch countdown.
A short time ago, the Atlas V’s first stage was loaded with room-temperature RP-1 fuel that will feed the main engine during the initial phase of the Kuiper 3 launch. Fueling of the rocket with cryogenic liquid oxygen to the main stage and liquid hydrogen and liquid oxygen to Centaur occurs in the final hours of the countdown.
Launch of the Atlas V to deploy the next 27 Project Kuiper satellites remains scheduled for Thursday morning from Cape Canaveral.

September 23:
The Atlas V rocket is emerging from the Vertical Integration Facility for its trip to Space Launch Complex-41 at Cape Canaveral. Ground crews are readying the rocket to carry the next Project Kuiper satellites into space for Amazon. Liftoff is planned for Thursday at 8:09 a.m. EDT (1209 UTC).
September 22:
The LRR, led by ULA Launch Director Ron Fortson, was completed this morning at the Advanced Spaceflight Operations Center (ASOC).
Leadership from ULA, Amazon and Space Force assessed the readiness of the rocket, payload and mission assets, discussed the status of pre-flight processing work, heard technical overviews of the countdown and flight, and previewed the weather forecast that projects an 85 percent chance of meeting the launch rules.
At the conclusion of the meeting, senior leaders were polled and gave a ready status for launch, then signed the Launch Readiness Certificate.
The Atlas V rocket, designated AV-108, stands 205 feet (62.5 meters) tall and will launch the Kuiper 3 payload into near-circular low Earth orbit (LEO) of approximately 280 miles (450 km) and 51.9 degrees inclination. At liftoff, the rocket generates a combined thrust of 2.7 million pounds (12 megaNewtons) from its main engine and five solid rocket boosters.
