Exploration Upper Stage: History & Measurement

The Exploration Upper Stage (EUS) was a planned rocket stage for NASA's Space Launch System (SLS) during 2013 to 2026. It was intended for use on the proposed SLS Block 1B and Block 2 configurations, replacing the Interim Cryogenic Propulsion Stage (ICPS) used on the Block 1 variant. The EUS was designed to be powered by four RL10C-3 engines burning…
