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
  1. Volume Reduction: The TCPS compresses waste into tiles, reducing its volume by up to 75%.
  2. Water Reclamation: Nearly all water content from wet trash is recovered for reuse.
  3. Radiation Shielding: The compacted trash tiles serve as an added layer of protection against cosmic rays.
  4. Catalytic Oxidizer: The system includes a Catalytic Oxidizer (CatOx) to eliminate volatile organic compounds and other harmful gases.
Table 1: Benefits of the TCPS Technology
Feature Benefit
Volume Reduction Frees up space and makes waste storage manageable
Water Reclamation Increases resource efficiency for long missions
Radiation Shielding Protects astronauts from harmful space radiation
Catalytic Oxidizer Keeps the habitat safe from 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.

Table 2: Waste Processing Comparison

Current Method TCPS Method
Trash packed in resupply vehicles Trash compacted into dense, safe tiles
Water from waste not reclaimed Nearly all water content recovered
Trash burned up during re-entry Waste stored for use as radiation shielding
No processing of harmful gases Catalytic Oxidizer neutralizes harmful VOCs

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.

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.

SpaceX’s Broader Role in Space Exploration

In addition to the U.S. Deorbit Vehicle, SpaceX is heavily involved in other significant NASA missions. SpaceX is developing the Human Landing System (HLS), specifically the Starship HLS, which will transport astronauts to the lunar surface as part of the Artemis III and IV missions. Furthermore, SpaceX has been contracted to launch the core elements of the Lunar Gateway—the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO)—into lunar orbit using a Falcon Heavy rocket in November 2025.

The ISS: A Platform for Scientific Advancement

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 the Outer 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.
