Development of a Modular Plasma-Activated Fog System for Enhanced Planetary Protection and Contamination Control

AAPlasma LLC proposes the development of a Modular Plasma-Activated Fog System (MPAFS) to advance planetary protection and contamination control measures. This system leverages non-equilibrium plasma-activated fog to disinfect surfaces and equipment efficiently, addressing the significant challenges of spacecraft cleaning and in-situ decontamination. The project aims to mitigate undesired microbial, particulate, and molecular contamination, which is crucial for ensuring the integrity of NASA missions and compliance with planetary protection requirements. Phase I of this SBIR will support the prototype development of this innovative technology. Once fully developed by the conclusion of Phase II, the MPAFS promises to offer a versatile solution for decontamination, capable of being adapted to various applications and settings, thereby catering to both space and terrestrial needs. This technology, having demonstrated efficacy in reducing pathogens significantly without causing damage to sensitive equipment, stands to benefit multiple sectors by providing an effective, low-resource consumption method for preventing cross-contamination between sample collections during spacecraft missions.
Benefits: The Modular Plasma-Activated Fog System (MPAFS) directly supports NASA's mission directives by offering a novel solution for spacecraft sterilization and planetary protection. This technology ensures the rigorous cleanliness required for scientific instruments and hardware, crucial for preventing forward and backward contamination. By preventing the transfer of organisms and/or potential genetic material from Earth to other planetary bodies and vice versa, MPAFS aligns with NASA's objectives for maintaining the integrity of scientific data and protecting Earth's biosphere from potential extraterrestrial biological threats. Its ability to decontaminate sensitive equipment without physical damage or the use of harsh chemicals presents a significant advantage for space missions, particularly those involving sample collection and analysis on other planets or moons. The commercialization opportunities for the Modular Plasma-Activated Fog System extend beyond NASA applications, particularly in the healthcare sector, food preservation, and public space sanitation. With proven effectiveness in disinfecting personal protective equipment (PPE) during the COVID-19 pandemic and extending the shelf life of fresh produce (previously-funded applications), MPAFS offers a solution to critical challenges faced by hospitals, agricultural sectors, and public health authorities. The system's low operational costs, minimal resource requirements, and adaptability to disinfect various items make it an attractive option for rapid disinfection processes, addressing the urgent need for efficient sterilization methods in response to pandemics and routine microbial control in various commercial and institutional settings.
