NASA Overhauls Science Mission Selection Process to Reduce Costs and Accelerate Development
NASA announced Competition Model 2.0 on October 21, restructuring how it evaluates and funds science missions to emphasize scientific merit over engineering complexity and cut proposal timelines nearly in half.
What happened
NASA Administrator Jared Isaacman directed the Science Mission Directorate to implement Competition Model 2.0, announced by Associate Administrator Nicky Fox on October 21. The reform restructures the agency's mission selection process across different mission classes. For mid-sized programs (Discovery, New Frontiers, and Astro-Probes), initial proposals will focus on scientific objectives and preliminary plans rather than detailed engineering and financial data, reducing the selection timeline from 35 months to approximately 19.5 months. Medium-class Explorer and Earth Explorer missions will open to universities and commercial organizations alongside traditional competitors. Smaller programs (SMEX, Earth Venture, and Missions of Opportunity) will move to single-stage selection, dropping timelines from 32 months to 19 months. Flagship missions will continue following current procedures. NASA will evaluate teams based on track records with similarly-sized projects and offer principal investigator-led teams access to support from Goddard Space Flight Center or Jet Propulsion Laboratory.
Context
The existing two-step process required competing teams to submit thorough engineering and financial details upfront, consuming significant resources from teams that might never be selected—a burden NASA leadership acknowledged had become too heavy. By deferring detailed engineering and cost planning until after initial scientific evaluation, CM 2.0 aims to lower barriers to entry and encourage innovation. The reforms emphasize Goddard and JPL's roles in mission development to reduce inter-center competition while preserving workforce expertise. The changes assume commercial space capabilities are maturing enough to support smaller missions cost-effectively. NASA is also implementing stricter cost and schedule controls, with breaches potentially triggering mission cancellations. Together, these shifts signal an effort to accelerate the pipeline from scientific idea to orbit while reducing financial burden on research institutions and universities seeking to compete for NASA funding.
