NASA’s Marshall Space Flight Center (MSFC) has issued a draft request for proposals (DRFP) for the Engineering Services and Science Capability Augmentation (ESSCA) II contract, aimed at soliciting feedback and questions from industry stakeholders before the final solicitation is released. The contract will support MSFC, including the Michoud Assembly Facility (MAF) and Stennis Space Center (SSC), as well as other NASA centers and headquarters, by providing a range of engineering and scientific skillsets. Key disciplines include aerosciences, avionics, flight software, materials research and testing, optics, propulsion, systems engineering, structural and mechanical expertise, test design, operability, and thermal and fluids analysis. The contractor may be required to supply engineering products, deliverables, and provide technical oversight for NASA’s flight, science, and research and development missions. ESSCA II is planned as a single-award, indefinite-delivery, indefinite-quantity (IDIQ) contract using a mix of cost-plus-award-fee, cost-plus-fixed-fee, and firm-fixed-price orders under NAICS code 541715.
