Evaluation of the Accumulation of Foreign Object Debris in the International Space Station Ventilation Systems and Resulting Impacts to Systems
A challenge for the International Space Station (ISS) is accumulation of foreign object debris (FOD) in the ventilation systems and the impacts to crew, equipment, and experiments. One function of the temperature and humidity control system is to capture FOD with various methods of filtration to minimize these impacts. ISS filtration has been augmented by charcoal and High Efficiency Particulate Air (HEPA) filters and screens. A qualitative comparison of the quantity of FOD found since 2012 study and the current levels are evaluated. Impacts due to FOD are reduced air circulation, increased crew time for cleaning, reduction of equipment life, and component damage; examples are provided. Recommendations for further improvements to reduce the accumulation of FOD on ISS are provided.

Integrated ECLSS Ground Testbed Development and Status for 2025
The reliability of Spacecraft Life Support systems and the associated mass needed to support human spaceflight is one of the largest risks for missions beyond Low Earth Orbit. The reliability of these systems directly corresponds to the number of spares needed to support the mission. Performance improvements for these systems can reduce the consumables needed for long-duration missions. The only integrated spacecraft regenerative Life Support System exists in Low Earth Orbit. It is not practical to use the ISS system to fully understand the reliability of the technology as these systems are currently maintaining a livable environment and crew’s lives are dependent on the availability of these systems. To achieve advancement on reliability and mass, NASA has initiated the development of an Integrated ECLSS ground Testbed. This paper will provide a status on the testbed development, hardware development and areas for investigation. This paper will also cover planned testbed integration and support for Earth Independent Operations (EIO). This paper will be relevant to sessions: 205, 300, 301, 404, 406, 500, 50, 506, and 511.
