NASA’s Launch Services Program is seeking statements of interest for Multi-Mission Commercial Launch Services, intending a full and open competition for at least eight full-mission-assurance launches to High C3, Lagrange/Lunar, Sun Synchronous, and Low Earth orbits in 2030–2031. Proposed launch vehicles must have development tests demonstrating at least 50% flight thrust at the full-scale single-engine assembly level for all core-stage engines; conceptual or design-stage vehicles will not be considered. The RFI is market research to collect industry feedback on the planned procurement process and evaluation strategy via an attached questionnaire, and eligibility is restricted to U.S. commercial entities under the Commercial Space Act. NASA plans a virtual Industry Day on November 12–13, 2026, with optional 60-minute one-on-one meetings; topic recommendations are requested by November 10, 2026, and RSVPs by November 9, 2026, 3:00 PM EST.
