Atlas 5

The Atlas V configuration for the mission is powered by dual RL10A-4-2 engines, each producing 10,251 kg (100.5 kilo-Newtons) of thrust.

The Atlas V Starliner launch countdown features a four-hour planned built-in hold at the T-minus 4-minute mark to allow the rocket to be fueled and placed in a quiescent state before astronaut boarding.

An Atlas V rocket will launch Boeing’s CST-100 Starliner spacecraft on the Crew Flight Test (CFT) mission to the International Space Station on 2024-05-06 at 10:34 p.m. EDT.

Two solid rocket boosters (SRBs) provide additional liftoff thrust for this Atlas V configuration, with each SRB providing 158,077 kg (1.55 mega-Newtons) of thrust.

Launch of the ULA Atlas V rocket and Boeing Starliner spacecraft is targeted for 10:34 p.m. EDT on 2024-05-06 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The Atlas V Starliner configuration modified for CST-100 Starliner does not include a payload fairing and instead uses the Starliner’s insulated surfaces for ascent protection.

United Launch Alliance is readying the Atlas V rocket for a flight test targeted for launch on 2024-05-06 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The Atlas 5 rocket will launch the CST-100 Starliner on the Crew Flight Test (CFT) mission no earlier than the evening of 2024-05-06.

Boeing’s CST-100 Starliner was hoisted into place atop the Atlas 5 rocket in the Vertical Integration Facility at Space Launch Complex 41 on 2024-04-16.

United Launch Alliance has been planning a transition from the Atlas 5 and Delta 4 Heavy to the next-generation Vulcan Centaur rocket powered by Blue Origin’s BE-4 engines.

United Launch Alliance launches Atlas V vehicles from LC-41 at Cape Canaveral and from SLC-3E at Vandenberg Space Force Base, California.

ULA launches its Atlas V vehicle from Launch Complex 41 at Cape Canaveral and LC-3E at Vandenberg.

ViaSat‑3 F2 was originally set to fly on a United Launch Alliance Atlas V rocket last fall and is now slated to launch in the first half of 2025.

Most previous Cygnus missions launched on Northrop Grumman’s Antares rocket, except two that launched on United Launch Alliance Atlas V vehicles after an Antares launch failure in 2014.
