Introduction
Waste management in space is a complex yet critical aspect of long-term human space exploration. As humanity aims for missions to the Moon, Mars, and beyond, effective waste processing systems are essential. The new Trash Compaction and Processing System (TCPS) developed by Sierra Space, in collaboration with NASA, could mark a significant breakthrough in sustainable space operations.
The Problem
Currently, managing garbage on the ISS is not ideal for long-term missions. Every astronaut on the ISS generates waste, including food wrappers, wipes, and old clothes, which are collected and stored temporarily. At present, all the trash is packed into resupply vehicles like the Russian Progress ship or Northrup Grumman’s Cygnus, which later burn up in the atmosphere. This practice works for ISS missions but would not be feasible for journeys to Mars or long-term lunar bases.
Challenges with Current Waste Disposal Methods
Space limitations: Garbage takes up valuable room on spacecraft.
Health hazards: Wet trash can generate harmful gases and bacteria if left unattended.
Resource wastage: No current system reclaims water or gases from the waste.
NASA recognizes the need for a self-sustaining and environmentally friendly waste management system. This led to the development of the TCPS, a device designed to solve multiple issues associated with space trash.
The Innovation: Trash Compaction and Processing System (TCPS)
The TCPS is a state-of-the-art machine developed by Sierra Space that reduces waste volume, extracts resources, and provides additional radiation protection. Its development marks a major advancement in waste processing technology for space exploration.
Key Features of the TCPS
Volume Reduction: The TCPS compresses waste into tiles, reducing its volume by up to 75%.
Water Reclamation: Nearly all water content from wet trash is recovered for reuse.
Radiation Shielding: The compacted trash tiles serve as an added layer of protection against cosmic rays.
Catalytic Oxidizer: The system includes a Catalytic Oxidizer (CatOx) to eliminate volatile organic compounds and other harmful gases.

“Long-term space travel requires the efficient use of every ounce of material and every piece of equipment. Every decision made on a spacecraft can have far-reaching consequences, and waste management becomes a matter of survival and mission integrity in the vacuum of space.” — Tom Vice, CEO of Sierra Space
How TCPS Works
The TCPS is a stand-alone system designed for ease of use. It requires only access to power, data, and air-cooling interfaces. Once installed, the TCPS will compact trash using heat and pressure, turning waste into dense, square tiles. These tiles are safe to store and handle, and they provide the added benefit of shielding against cosmic radiation.
The TCPS’s Catalytic Oxidizer neutralizes harmful gases released during the compaction process. This ensures that the space environment remains safe and sterile, protecting the crew from possible health hazards.
Sierra Space emphasizes that the TCPS is a leap forward in sustainable space technology. By reclaiming water from waste and using trash tiles for radiation protection, the system minimizes resource wastage and optimizes space use.

Why TCPS is Crucial for Future Space Missions
Long-Duration Space Travel
Missions to Mars could take anywhere from 6 to 9 months one way. Efficient waste management is not just about hygiene but also about survival. The TCPS will enable astronauts to reclaim valuable resources and minimize the impact of waste on living quarters.
Radiation Protection
One of the biggest threats to astronauts on long-term missions is space radiation. Currently, radiation protection relies on heavy shielding materials that add to the spacecraft’s weight. Using waste tiles as an additional barrier offers a clever and resource-efficient solution.
Health and Safety
In confined spaces like spacecraft, waste buildup can create serious health hazards. Harmful gases and bacteria can endanger the crew if not properly managed. The TCPS ensures a safe and sterile environment by using the Catalytic Oxidizer to neutralize these threats.
The Heat Melt Compactor created a sample trash tile. It compressed the trash to less than one-eighth of its original volume. NASA provided the information.
Future Testing and Deployment
NASA plans to test the TCPS on the ISS by late 2026. The initial ground tests have shown promise, and Sierra Space is finalizing the Flight Unit for space testing. If successful, the TCPS will be a game-changer for long-duration missions.
Initial Design and Review
Sierra Space was first awarded a contract in 2023 and completed the design phase in early 2024. Following rigorous reviews, NASA approved the development of a Flight Unit. The TCPS Ground Unit is already undergoing system evaluations, ensuring its readiness for deployment.
The TCPS isn’t just a trash compactor. It’s a revolutionary system that supports NASA’s Artemis program, the Lunar Gateway, and even potential Mars colonization efforts. Waste management and resource efficiency are two crucial aspects of establishing a sustainable human presence beyond Earth.
Artemis Missions: The TCPS will ensure efficient waste processing on the Lunar Gateway, supporting the long-term stay of astronauts on the Moon.
Mars Exploration: With journeys to Mars expected to be lengthy, the TCPS provides a solution for handling waste and protecting the crew from radiation.
Facts About Waste Management in Space
Astronauts generate about 2.5 pounds of waste daily.
Wet trash can be more dangerous than dry trash due to bacteria growth.
Compacted trash tiles could serve as building blocks for future space habitats.
The TCPS reduces the need for frequent trash disposal trips back to Earth.
Resource reclamation is crucial, as water in space costs thousands of dollars per gallon.

The New SpaceX Dragon Capsule Designed to De-Orbit the ISS
The International Space Station (ISS) has been a remarkable symbol of international collaboration and scientific advancement for over 25 years. Since its launch, it has hosted over 270 astronauts, cosmonauts, and commercial astronauts from various space agencies around the world. As the ISS approaches the end of its operational life, plans for its safe deorbit and disposal have been set in motion. In January 2031, a specially designed spacecraft by SpaceX, known as the U.S. Deorbit Vehicle, will undertake the critical task of de-orbiting the ISS. On July 17th, NASA held a live press conference to unveil the details of this mission, including a first look at the modified SpaceX Dragon capsule responsible for the deorbit process.
Unveiling the U.S. Deorbit Vehicle
During the press conference, NASA revealed several key features of the U.S. Deorbit Vehicle. SpaceX shared details and an image of the special Dragon via their official X account (formerly Twitter). According to SpaceX, the modified spacecraft will have six times the propellant and four times the power of today’s Dragon spacecraft. The image released shows a robust service module replacing the trunk used by the standard Crew Dragon vehicle. This new service module is larger and equipped with additional fold-out solar arrays, as well as hull-mounted solar panels, to provide the necessary power for the mission.
The modified Dragon capsule also appears to have more Draco engines than the standard Crew Dragon vehicle. The standard Crew Dragon is equipped with 18 Draco engines, each capable of generating 400 Newtons (90 lbf) of thrust, totaling 7,200 N (360 lbf) of thrust. The U.S. Deorbit Vehicle is expected to have 72 Draco thrusters arranged concentrically, capable of generating close to 30,000 Newtons (1,440 lbf) of thrust. This significant increase in thrust power is crucial for the controlled deorbit of the massive ISS structure. The image also shows the spacecraft docking with the Kibo module operated by the Japan Aerospace Exploration Agency (JAXA).
Contract and Development
NASA announced the selection of SpaceX in late June to develop the U.S. Deorbit Vehicle as part of a single-award contract valued at up to $843 million. While SpaceX is responsible for the development of the spacecraft, NASA will take ownership once it is complete and operate it throughout the mission. The spacecraft, along with the ISS, is expected to break up during re-entry, with the remains landing in the “spacecraft cemetery” in the South Pacific. The contract for the launch services has not yet been awarded but is expected to be announced shortly.
Since its launch in 1998, the ISS has served as a unique platform for scientific research and technological demonstrations that are not possible on Earth. The ISS is a collaborative effort involving five space agencies: NASA, the Canadian Space Agency (CSA), the European Space Agency (ESA), JAXA, and the Russian State Space Corporation (Roscosmos). Throughout its operational lifetime, the ISS has hosted a wide range of experiments, including studies on the effects of microgravity and space radiation on human, animal, and plant physiology. This research is crucial as NASA and its international partners plan for long-duration missions to the Moon and Mars in the coming decades.
A Symbol of International Cooperation
Beyond its scientific contributions, the ISS stands as a symbol of international cooperation and peaceful use of outer space, in line with theOuter Space Treaty and its core philosophy that “space is for all.” NASA, CSA, ESA, and JAXA have all committed to operating the ISS through 2030, while Roscosmos has committed to continue operations until at least 2028. The safe deorbit of the ISS is a shared responsibility among all five space agencies, ensuring a controlled re-entry and disposal process.
Enhanced Capabilities of the U.S. Deorbit Vehicle
The U.S. Deorbit Vehicle is a big improvement over the current Dragon spacecraft. It has six times more fuel and four times more power. This modified spacecraft can de-orbit the ISS. De-orbiting means guiding the space station back into the Earth’s atmosphere.
The vehicle has a strong service module. A service module is the part of the spacecraft that holds the main systems, like power and propulsion. It also has more solar panels to collect energy from the sun. Additionally, it comes with more Draco engines. Draco engines help the spacecraft move in space. All these upgrades are important. They help the spacecraft do its job well.
The service module is particularly noteworthy. Unlike the standard Crew Dragon vehicle, which uses a trunk for storage and supports various mission operations, the U.S. Deorbit Vehicle’s service module is larger and more powerful. The additional fold-out solar arrays and hull-mounted solar panels ensure that the spacecraft has the necessary power to sustain its systems and perform the de-orbit burn.

Draco Engines: Powering the Mission
The increased number of Draco engines is another significant modification. The standard Crew Dragon’s 18 Draco engines generate a total thrust of 7,200 Newtons (360 lbf). In contrast, the U.S. Deorbit Vehicle will feature 72 Draco thrusters, arranged concentrically, capable of generating close to 30,000 Newtons (1,440 lbf) of thrust. This substantial increase in thrust is essential for maneuvering the massive ISS and ensuring a controlled deorbit.
To put this into perspective, the standard Crew Dragon’s Draco engines are designed for precise maneuvering and controlling the spacecraft’s orientation. However, the U.S. Deorbit Vehicle’s mission requires more power to lower the ISS’s orbit and ensure it re-enters Earth’s atmosphere at the correct trajectory. The additional engines and increased thrust capacity will provide the necessary control and power for this critical operation.
Docking with the Kibo Module
The image released by SpaceX shows the U.S. Deorbit Vehicle docking with the Kibo module, a Japanese experiment module operated by JAXA. The Kibo module is one of the largest and most versatile modules on the ISS, featuring an external platform for experiments exposed to the space environment, a logistics module for storage, and an airlock for deploying satellites and other payloads. The U.S. Deorbit Vehicle’s docking with the Kibo module underscores the collaborative nature of the ISS program, involving multiple international partners.
Financial and Operational Aspects
The $843 million contract awarded to SpaceX underscores the significant financial investment in the safe deorbit of the ISS. While SpaceX is responsible for developing the U.S. Deorbit Vehicle, NASA will own and operate the spacecraft once it is completed. This arrangement highlights the collaborative effort between NASA and SpaceX, combining SpaceX’s innovative spacecraft development capabilities with NASA’s operational expertise.
SpaceX’s Role in Future Space Missions
In addition to the U.S. Deorbit Vehicle, SpaceX’s involvement in the Artemis program and the Lunar Gateway project demonstrates the company’s integral role in future space missions. The Starship HLS, developed by SpaceX, will transport astronauts to the lunar surface as part of NASA’s Artemis missions. The Artemis III and IV missions are crucial steps toward establishing a sustainable human presence on the Moon and preparing for future missions to Mars.
SpaceX’s contract to launch the core elements of the Lunar Gateway—the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO)—further cements the company’s role in NASA’s lunar exploration plans. The Lunar Gateway will serve as a space station in lunar orbit, providing support for long-term human exploration of the Moon and beyond. The Falcon Heavy rocket, which will launch the PPE and HALO into lunar orbit, is one of SpaceX’s most powerful launch vehicles, capable of carrying heavy payloads to deep space destinations.
The Scientific Legacy of the ISS
The ISS has been a cornerstone of scientific research in space for over two decades. It has enabled countless experiments and technology demonstrations that have advanced our understanding of space science, biology, physical sciences, and technology development. Some notable areas of research include the effects of microgravity on human health, plant growth in space, and the development of new materials and technologies that can withstand the harsh conditions of space.
For example, studies on the ISS have provided valuable insights into how microgravity affects muscle and bone density, cardiovascular health, and immune system function. These findings are critical for preparing astronauts for long-duration missions to the Moon and Mars, where they will be exposed to the space environment for extended periods.
In addition to biological and physiological research, the ISS has also hosted experiments in fundamental physics, materials science, and Earth observation. These experiments take advantage of the unique conditions of space to explore phenomena that cannot be studied on Earth. The knowledge gained from these experiments has applications beyond space exploration, contributing to advancements in medicine, materials science, and environmental monitoring.
A Symbol of Peaceful Cooperation
The ISS is not only a scientific laboratory but also a symbol of peaceful cooperation among nations. The collaboration between NASA, CSA, ESA, JAXA, and Roscosmos demonstrates how countries can work together to achieve common goals in space exploration. This spirit of cooperation is enshrined in the Outer Space Treaty, which promotes the peaceful use of outer space and the principle that space is the province of all humankind.
The commitment of these space agencies to operate the ISS through 2030, and Roscosmos’ commitment through 2028, reflects their dedication to maintaining this symbol of international partnership. The safe deorbit of the ISS is a shared responsibility, ensuring that the legacy of cooperation continues even as the station’s operational life comes to an end.
The Future of Space Exploration
The deorbit of the ISS marks the end of an era, but it also paves the way for the next generation of space exploration. NASA and its international partners are already looking toward the future, with plans for the Lunar Gateway, Artemis missions, and eventual human missions to Mars. The knowledge and experience gained from operating the ISS will be invaluable as humanity takes its next steps into the cosmos.
Conclusion
The development of the U.S. Deorbit Vehicle by SpaceX marks a significant milestone in the safe deorbit and disposal of the ISS. With enhanced capabilities and a robust design, the modified Dragon spacecraft will ensure a controlled re-entry and minimize risks associated with the deorbit process. The ISS has been a cornerstone of scientific research and international cooperation for over 25 years, and its safe deorbit is a shared responsibility among NASA, CSA, ESA, JAXA, and Roscosmos.
As we look to the future, the lessons learned from the ISS will guide us in our exploration of the Moon, Mars, and beyond. The spirit of cooperation and discovery that the ISS embodies will continue to inspire future generations of scientists, engineers, and explorers.
