Sierra Space has secured a contract from NASA to develop and test its Trash Compaction and Processing System (TCPS) aboard the International Space Station by late-2026.

This new system is designed to play a key role in future space missions by improving waste management, stowage, and water reclamation on long-duration trips, including human missions to the Moon and Mars. The TCPS will help astronauts manage waste by significantly reducing its volume while reclaiming almost all of the water trapped within, making it available for reuse.

Current space waste management systems struggle with water recovery and volume reduction, key aspects necessary for long-term missions. The TCPS will overcome these challenges by recovering water from waste, which will be crucial not only for deep space exploration but also for commercial orbital facilities and extraterrestrial bases. The TCPS operates independently, requiring only power, data, and air-cooling connections, and features a user-friendly interface for the crew.

"Space travel requires the highly efficient use of material and equipment. Waste management is critically important, especially for long duration missions," said Sierra Space CEO, Tom Vice. "We're addressing this challenge through technological innovation and commitment to sustainability in every facet of space operations. Efficient, sustainable, and innovative waste disposal is essential for the success of crewed space exploration."

The system also features a Catalytic Oxidizer (CatOx), which processes volatile organic compounds (VOCs) and other gases to maintain a safe and clean space environment. This CatOx technology is more energy-efficient and safer than traditional VOC removal techniques and is also a component of Sierra Space's Environmental Controls and Life Support Systems (ECLSS). The TCPS compacts trash into solid tiles that are easy to store, safe to handle, and can offer radiation protection. Additionally, the CatOx technology eliminates harmful contaminants to ensure crew safety.

Sierra Space finished the initial design phase in January, presenting the TCPS for Critical Design Review with NASA. Now, the team is focused on finalizing the ground unit, which will undergo system evaluations before the flight unit is launched to the ISS for testing.

The project began with Phase A in May 2019, when Sierra Space developed a TCPS prototype. Phase B, initiated in August 2022, will continue with in-orbit testing through 2026 and beyond.
