In a significant stride towards addressing the escalating threat of space debris, the Southwest Research Institute (SwRI) has unveiled the development and successful testing of a novel micrometeoroid and orbital debris (MMOD) detection and characterization system. Designed for integration into satellites and other spacecraft, this technology offers a critical new layer of defense and data collection in Earth's increasingly crowded orbital environment. The MMOD system functions as a sophisticated "black box" for spacecraft, detecting impacts and gathering crucial post-impact data. It comprises a structural panel embedded with sensors that, in conjunction with advanced software, analyze impact events. This allows for immediate identification of a collision, even if the damage is too subtle for operators on Earth to notice. The collected data can provide a wealth of information, including the time and location of the impact, as well as the speed and composition of the debris involved.

The rising threat of space debris: This development arrives at a time when space debris is a growing concern for the global space industry. Caused by defunct satellites, rocket stages, and fragmentation events, the problem creates a "junk field" of particles orbiting at extreme velocities. These pieces of debris, even those as small as a fleck of paint, can inflict catastrophic damage on operational spacecraft and satellites. Traditional ground-based tracking systems are often unable to detect these smaller, yet highly dangerous, particles. "Most spacecraft survive minor impacts without systems breaking or operators on Earth knowing," said Dr. Sidney Chocron, an SwRI Institute Scientist who led the development of the MMOD system. "Our device is designed to send data back to Earth with important insights before any damage is apparent, which can also influence future design decisions."

Testing in a hypervelocity environment: To prove the system's effectiveness, SwRI utilized its specialized light gas gun facility to simulate the intense conditions of space. This powerful tool fired small projectiles at panels equipped with the MMOD detection system, replicating the hypervelocity impacts of real space debris. The results of these tests, detailed in a recent peer-reviewed study, demonstrate the system's ability to accurately detect and characterize impacts under realistic conditions. According to Dr. Chocron, these tests are vital not only for validating the new technology but also for informing the design of future spacecraft. The data gathered from the system could help engineers build more resilient satellites capable of withstanding the rigors of the orbital environment.
