NASA Working to Adapt Space Launch System for Multiple Payload Types

NASA is requesting industry proposals for a Universal Stage Adaptor (USA) that will provide options for additional payloads set to ride uphill on the Space Launch System (SLS). The USA will be able to host payloads in-between the Exploration Upper Stage (EUS) and Orion, or provide a role for cargo-only missions – the latter required to provide SLS with a viable flight rate.
