Revolutionary Exploration Upper Stage Enhances Crew Safety and Deep Space Power.

Boeing's Exploration Upper Stage (EUS) is a revolutionary leap in crew safety, cargo capacity, and deep space power. EUS will replace the Interim Cryogenic Propulsion Stage (ICPS) and allow NASA to send astronauts and large payloads to the Moon on a single mission. EUS provides 97,000 pounds of thrust during translunar injection versus nearly 25,000 pounds of thrust from ICPS. This added boost allows for 40 percent more payload to be sent to the Moon and beyond, enabling NASA to send more than 83,000 pounds of cargo on a single crewed mission.
