Provide a feasibility study of the Delta Cryogenic Second Stage (DCSS) as the SLS Interim Cryogenic Propulsion Stage (ICPS). This study will include an assessment of the DCSS: 1) against SLS load ...

To fulfill these requirements, Boeing will modify its existing Delta Cryogenic Second Stage (DCSS). NASA Solicitation: Interim Cryogenic Propulsion Stage for the Space Launch System Synopsis ...

Boeing's Delta cryogenic second stage (DCSS) has been selected as the interim upper stage for the first two flights of the Space Launch System (SLS), according to a justification on NASA's ...

Flying with a 4 meter payload fairing, a 4 m diameter Delta Cryogenic Second Stage (DCSS), a 5 m diameter Common Booster Core, and two strap on solid rocket motors, the final Delta IV Medium ...

This consists of a Common Booster Core first stage with an RS-68A engine, augmented by two GEM-60 solid rocket motors, and a four-meter Delta Cryogenic Second Stage powered by an RL10B-2.

A single RL10C-2-1 engine on the Delta cryogenic second stage then took over, propelling the NROL-70 payload into space. Due to national security concerns, ...

Atop the booster is a Delta Cryogenic Second Stage (DCSS), or upper stage, which is also fueled by cryogenic liquid hydrogen and liquid oxygen. It is powered by a single RL10C-2-1 engine, ...

WASHINGTON — The Space Launch System (SLS) heavy-lift rocket will use a modified Delta 4 upper stage provided by Boeing Co. for its first two missions, according to the terms of an eight-year ...

NASA will contract with Boeing for an interim cryogenic propulsion stage to power at least the first two flights of its planned heavy-lift Space Launch System (SLS), based on the company's Delta ...

How will this work? One heavy-lift rocket would launch a fully fueled upper stage—most likely a Delta Cryogenic Second Stage or the Centaur upper stage currently used on United Launch Alliance ...

Each of the Delta 4 Heavy’s common booster cores is powered by Aerojet Rocketdyone’s RS-68A main engines. The Delta cryogenic second stage is powered by an RL10C-2-1 engine.

The tanks also fuel Delta IV Heavy’s Delta Cryogenic Second Stage (DCSS), which is powered by a single RL10C-2-1 engine producing nearly 25,000 pounds of thrust.
