June 8, 2017 – NASA has selected Dynetics, Inc. of Huntsville, Alabama, to develop and build a universal stage adapter for the agency’s Space Launch System (SLS) rocket. The adapter will connect NASA’s Orion spacecraft and provide additional cargo space for the future configurations of the rocket containing an exploration upper stage (EUS).
Under the contract, Dynetics will design, develop, test, evaluate, produce and deliver the first universal stage adapter for the second integrated mission of SLS and Orion, known as Exploration Mission-2, or EM-2. This mission will be the first test flight with crew aboard NASA’s new deep space exploration systems.
This cost plus award fee contract has a maximum potential value of $221.7 million and a potential performance period of 11 years, which includes a four-year base period that begins August 1, and six options, allowing NASA to order up to six additional adapters for missions beyond EM-2.
The universal stage adapter will house and protect large co-manifested payloads, such as habitats and deep-space exploration spacecraft, and secondary payloads including CubeSats. NASA’s SLS with the exploration upper stage for EM-2 is expected to lift more than 105 metric tons (231,000 pounds) from the Earth’s surface.
The universal stage adapter will stand 32.4 feet tall and will measure 27.6 feet in diameter at its largest point, and will provide environmental control to payloads during ground operations, launch and ascent, while also accommodating the electrical and communication paths between the EUS and Orion.
