Kuiper 2, the launch of a United Launch Alliance (ULA) Atlas V 551 rocket carrying the second batch of production satellites for Amazon's Project Kuiper, is planned for June 13, 2025, pending range approval.
The launch is scheduled for 2:29 p.m. EDT at the opening of a thirty-minute window, from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida.

Mission Details
Project Kuiper (KA-02)
Project Kuiper is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,236 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km, and 630 km altitude.
Payloads: 27
Total Mass: 15,422.0 kg
Low Earth Orbit

The next United Launch Alliance (ULA) Atlas V launch has plenty of similarities to its previous flight but is no less significant. The Kuiper 2 mission, scheduled for June 16, will mark another step for Amazon's Project Kuiper to deploy an advanced broadband constellation in low Earth orbit (LEO).
Liftoff is scheduled during a launch window opening at 1:25 p.m. EDT (1725 UTC). ULA will provide play-by-play status reports from launch control beginning at 10 a.m. EDT (1400 UTC) and a live webcast starting at L-20 minutes.
Ascending from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, the Atlas V rocket will immediately execute pitch, yaw and roll maneuvers to align with a northeasterly heading for its 18-minute climb into a 51.9-degree, 280-mile-high (450 km) orbit.
Like the successful Atlas V Kuiper 1 mission on April 28, which delivered Amazon's first operational spacecraft into LEO, the upcoming Kuiper 2 mission will launch another batch of 27 satellites into space.
Launch preparations began May 22 at the ULA Vertical Integration Facility (VIF) by starting the assembly of rocket elements. The encapsulated Kuiper 2 payload was hoisted atop the rocket on June 5, marking one of the quickest integrations of the top-of-the-line Atlas V 551 launch vehicle.
The same Atlas V rocket configuration will be used as the inaugural Kuiper mission — with five side-mounted GEM 63 solid rocket boosters (SRBs), a 17.7-foot-diameter (5.4m) composite payload fairing and single RL10A-4-2 upper stage engine.

Atlas V stands 205 feet (62.5 m) tall, will weigh 1.3 million pounds (589,000 kg) once fueled for launch and lifts off on a combined thrust of 2.7 million pounds (12 megaNewtons) from its main engine and five SRBs.

The Kuiper payloads are the heaviest ever carried by an Atlas rocket at a total of 34,000 pounds (15,400 kg). The satellites ride into space attached to a special dispensing tower and release at predetermined intervals, representing the most separation events ever performed in a single Atlas launch.

Amazon is partnering with ULA to launch a majority of the Kuiper constellation using a total of eight Atlas V and 38 Vulcan rockets under the largest commercial launch services agreement in industry history.

Project Kuiper is built around an initial constellation of more than 3,200 advanced LEO satellites. Its mission is to provide fast, reliable internet to customers and communities around the world, including those unserved or underserved by traditional connectivity technologies. The system has the capacity, performance, and flexibility to serve a wide range of customers, from individual households to schools, hospitals, businesses, government agencies and other organizations operating in places without reliable connectivity.

The countdown is in the planned 30-minute hold. This block of time ensures all steps in the procedure prior to cryogenic propellant loading are complete and satisfactory before the start of #AtlasV tanking.
The pad is clear and weather is GO.

We are passing Launch Minus-2 hours in the countdown. Tanking operations are proceeding nominally after beginning at the earliest opportunity in our timeline today. All activities remain on schedule for a liftoff at 1:25:30 p.m. EDT (1725:30 UTC).

LAUNCH STATUS UPDATE:

The launch of a United Launch Alliance Atlas V 551 carrying Amazon's second Project Kuiper mission, Kuiper 2, is delayed due to an engineering observation of an elevated purge temperature within the booster engine. The team will evaluate the hardware, and we will release a new launch date when available.

Отложен!

Запуск ... задерживается из-за инженерных наблюдений повышенной температуры продувки в разгонном двигателе. Команда оценит оборудование, и мы объявим новую дату запуска, когда она станет доступна.
