Low-Cost NASA Missions Yield Less Science

A recent paper presented at the 57th Lunar and Planetary Science Conference analyzes the scientific output of 90 NASA missions launched between 1994 and 2023. The study, conducted by Ari Koeppel and Casey Dreier of the Planetary Society, challenges the trend towards low-cost missions, arguing that they do not generate high-impact science. The analysis focused on missions costing less than $100 million and measured their success based on the number of resulting papers with over 100 citations, defined as "high-impact." The findings indicate that very-low-cost planetary science missions have produced no high-impact papers, while astrophysics missions in the same budget category yielded only 0.02% of such papers. Heliophysics missions performed slightly better, accounting for 7.9% of high-impact papers in that division. The authors addressed the potential time bias in citation counts by analyzing the production rates of papers over time. However, even with this adjustment, the low-cost missions did not show significant improvement. The study also examined the "time-to-science," finding that low-cost missions often take years to publish highly cited results, negating their supposed rapid development advantage. The authors attribute the difficulties faced by low-cost missions to higher failure rates, with nine missions costing less than $100 million failing to produce any science at all. The research suggests that a shift in funding strategies may be necessary to ensure that NASA missions are able to generate meaningful scientific discoveries. The study highlights the importance of balancing cost-effectiveness with the need for robust scientific research. The findings have implications for the future of NASA's mission planning and funding allocation. The research underscores the need for a more strategic approach to space science funding, one that prioritizes high-impact research over simply minimizing costs.
