A critical global infrastructure challenge is now the focus of a groundbreaking crowdsourcing initiative spearheaded by NASA’s Center of Excellence for Collaborative Innovation (CoECI) and its NASA Tournament Lab (NTL). The "Crack the Case" challenge, officially launched on March 12, 2026, invites a diverse array of experts—including geophysicists, sensing specialists, nondestructive testing (NDT) experts, and artificial intelligence/machine learning (AI/ML) practitioners—to develop innovative solutions for detecting subsurface cracks within embankment dams. This multi-phase competition, offering a total of $400,000 in prizes, aims to transform the current state of dam safety monitoring, moving from conceptual approaches to real-world demonstration of deployable technologies.
The Imperative of Dam Safety: A Global Challenge
Embankment dams, constructed primarily from compacted earth or rock fill, constitute the vast majority of the world’s approximately 60,000 large dams. These structures are vital components of modern infrastructure, providing essential services such as hydropower generation, flood control, irrigation, and potable water supply for billions globally. However, their structural integrity is paramount, as failures can lead to catastrophic consequences, including immense economic losses, widespread environmental devastation, and significant loss of life.
The aging infrastructure of many dams exacerbates these concerns. In the United States alone, the average age of a dam is over 50 years, with a substantial portion exceeding their original design lifespan. Globally, similar trends are observed, placing immense pressure on maintenance and monitoring systems. A key challenge in maintaining embankment dams is the difficulty of detecting internal defects, such as subsurface cracks, seepage pathways, or internal erosion, before they manifest as visible structural distress or lead to a breach. Current detection methods can be invasive, costly, time-consuming, and may not always provide the comprehensive, real-time data necessary for proactive risk management.
Historical incidents underscore the critical need for improved detection. The 1976 Teton Dam collapse in Idaho, for instance, was attributed to internal erosion, a process that could have been mitigated with earlier, more accurate detection of subsurface anomalies. More recently, the 2017 Oroville Dam spillway incident in California highlighted the vulnerabilities even in modern structures and the enormous financial and logistical challenges associated with emergency repairs and infrastructure resilience. Reports from organizations like the American Society of Civil Engineers (ASCE) consistently give dams a mediocre grade, emphasizing the need for significant investment and technological advancement in monitoring and maintenance. The International Commission on Large Dams (ICOLD) similarly stresses the ongoing need for research and development into advanced monitoring techniques to enhance dam safety worldwide.
NASA’s Unconventional Role: Leveraging Crowdsourcing for Terrestrial Impact
While NASA is primarily known for space exploration, its involvement in terrestrial challenges like dam safety is a testament to its commitment to applying advanced technological and problem-solving methodologies developed for space to benefit life on Earth. The Center of Excellence for Collaborative Innovation (CoECI) was established precisely for this purpose: to assist federal agencies in leveraging crowdsourcing and open innovation methodologies. CoECI’s NASA Tournament Lab (NTL) serves as the operational arm, providing the contractual capability to design, launch, and manage external crowdsourced challenges for NASA and other government entities.
The NTL model has a proven track record of success across a wide range of scientific and engineering domains. From optimizing algorithms for space robotics and satellite imagery analysis to developing innovative solutions for health challenges and Earth observation data processing, the NTL has consistently demonstrated the power of tapping into global expertise. By casting a wide net, crowdsourcing allows agencies to access diverse perspectives, cutting-edge research, and interdisciplinary approaches that might not be available through traditional procurement channels. This method accelerates innovation, often at a lower cost, and yields more diverse and creative solutions. NASA’s involvement in "Crack the Case" is a direct application of this philosophy, recognizing that the advanced sensing, data analysis, and predictive modeling expertise cultivated for complex space missions can be incredibly valuable in addressing critical infrastructure needs here on Earth.
