Liftoff Set for 7 p.m. ET
BREVARD COUNTY • CAPE CANAVERAL, FLORIDA – The Launch Readiness Review (LRR) is GO for Wednesday’s liftoff of the United Launch Alliance Atlas V rocket with the first production satellites for Amazon’s Project Kuiper constellation.
Liftoff is scheduled for 7 p.m. ET from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The available launch window extends two hours.
The LRR, led by ULA Launch Director Eric Richards, was completed this morning at the Advanced Spaceflight Operations Center (ASOC).
Leadership from ULA, the Space Force and Amazon 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 a 65 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-107, stands 205 feet (62.5 meters) tall and will launch the Kuiper 1 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.
ULA will offer live reports from launch control in our automatically refreshing blog beginning Wednesday at 4 p.m. ET. The launch webcast starts at 6:35 p.m. ET.
Coverage of the launch can be seen on Space Coast Daily TV.
