NASA Crater Detection Challenge
NASA’s Lucy spacecraft recently made headlines by capturing stunning images of the Moon’s surface during its flyby of Earth on October 16, 2022. This event marked the first of three gravity assists that the spacecraft will utilize to reach its ultimate destination: the Trojan asteroids that orbit the Sun in tandem with Jupiter. As part of its mission, Lucy aims to gather invaluable insights into the early solar system by studying these ancient celestial bodies. However, the images taken during this flyby also highlight a significant challenge in planetary science: the detection and analysis of lunar crater rims, which are crucial for navigation and understanding the Moon’s geological history.
Detecting crater rims in natural imagery is no simple task due to various factors such as lighting conditions, shadows, and the irregularities of crater edges. These elements can obscure the true shape of craters, making it difficult for scientists and navigation systems to accurately interpret the data. To address this challenge, NASA has launched a project that encourages innovators and researchers to develop algorithms capable of reliably detecting and fitting ellipses to crater rims in lunar imagery. This initiative not only aims to enhance the accuracy of crater detection but also seeks to advance the future of terrain-based optical navigation. By employing a visible-light camera on spacecraft, the goal is to capture high-quality orbital images of the Moon’s surface, enabling the identification of craters from a catalog and estimating the spacecraft’s position based on these identified features.
To incentivize participation in this groundbreaking project, NASA is offering a total prize pool of $55,000 for those who can contribute effective solutions. The competition opens on November 25, 2025, and will close on January 19, 2026, inviting a wide range of participants to engage in this critical area of research. As the field of space exploration continues to evolve, the ability to accurately detect and analyze lunar craters will play a pivotal role in future missions, potentially paving the way for more sophisticated navigation systems and a deeper understanding of our celestial neighbor.

NASA’s Lucy spacecraft captured images of the Moon’s surface on Oct 16, 2022, after flying by the Earth for its first of three gravity assists.
Crater rims are vital landmarks for planetary science and navigation. Yet detecting them in real imagery is tough, with shadows, lighting shifts, and broken edges obscuring their shape.
This project invites you to develop methods that can reliably fit ellipses to crater rims, helping advance future space exploration.
In the pursuit of next generation, terrain-based optical navigation, NASA is developing a system that will use a visible-light camera on a spacecraft to capture orbital images of lunar terrain and process the imagery to:
detect the crater rims in the images,
identify the craters from a catalog, and
estimate the camera/vehicle position based on the identified craters.
The focus of this project is the crater detection process.
Natural imagery varies significantly in lighting and will impact the completeness of crater rims in the images.
