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 Grummanβs 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%.

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 NASAβs 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.

How Accessible is Titanium on the Moon? A Closer Look at Lunar Resources
Titanium, a valuable metal used in industries such as aerospace and manufacturing, is abundant on the Moon, primarily found in the mineral ilmenite. While titanium extraction on the Moon presents significant challenges, such as transporting heavy machinery and powering it in an airless environment, it holds promise for future space exploration. Ilmenite mining could also serve a dual purpose by providing oxygen for rocket fuel or breathable air, making it a valuable resource. Though titanium mining is not yet economically feasible, technological advancements in the coming decades may make it a crucial part of space exploration and lunar colonization efforts.
Summary
Titanium’s presence on the Moon is mostly in the form of ilmenite.
Ilmenite, a titanium-iron oxide mineral, can also release oxygen when processed.
Earthβs titanium supply, especially from mines like Tellnes in Norway, is sufficient for current needs.
Transporting mining machinery to the Moon would require many rocket launches.
Using solar and nuclear energy to power the mining operations could be feasible.
It may take up to 20 years to scale mining operations to produce large amounts of titanium.
Early lunar mining efforts could focus on oxygen extraction rather than titanium.
The long-term benefits of lunar mining could support Earth industries and space exploration.
Mining titanium on the Moon might initially be more valuable for supporting space missions than for direct economic purposes on Earth.
Introduction
Mining the Moon is a concept long imagined in science fiction, but with modern space missions, itβs becoming a more tangible possibility. One of the most abundant resources found on the Moon is titanium, a valuable metal used in industries like aerospace, manufacturing, and nanotechnology. But how feasible is it to mine titanium from the lunar surface, and what would the process look like? To answer these questions, weβll dive into the scientific studies, current technologies, and future prospects of lunar titanium extraction.
Why is Titanium Important?
Titanium is prized for its strength-to-weight ratio and corrosion resistance, making it essential in building materials, especially for spacecraft and aircraft. On Earth, itβs valued at around $10,000 per ton, with a wide range of industrial applications. However, while we have abundant titanium deposits on Earth, the lure of mining titanium on the Moon stems from its potential to support space missions and even future colonization efforts.
Lunar Titanium: Abundance and Location
The Moonβs titanium is primarily contained in ilmenite, a black mineral composed of iron, titanium, and oxygen. Unlike Earth, where ilmenite is mined directly for titanium, lunar mining could serve a dual purposeβproviding oxygen for life support or rocket fuel alongside valuable titanium. According to researchers, ilmenite makes up about 20% of some lunar rocks found in areas like the Sea of Tranquility, where the Apollo missions landed.
How Much Titanium Could We Extract?
In a recent paper by Renaud Merle, Mikael HΓΆΓΆk, Valentin Troll, and Alexander Giegling from Uppsala University, scientists estimate the concentration of ilmenite in lunar soil. They compared this with the Tellnes mine in Norway, one of the most productive titanium mines on Earth. Tellnes produces about 750 kilotons of ilmenite annually, representing roughly 5% of the global titanium output.
In comparison, lunar ilmenite deposits in the Sea of Tranquility, with concentrations ranging from 3% to 15%, could potentially yield about 500 kilotons of titanium per year. However, achieving this would require 20 years of scaling up operations.
Here’s a close-up of a titanium lattice ball. It was made using a 3-D printer. The European Space Agency says it has a “complex external geometry.” This means its shape is intricate and detailed on the outside. We can’t make it with normal manufacturing methods. Credit goes to ESA for the image.
Mining Operations: Challenges and Solutions
Transporting Heavy Machinery
Mining equipment is heavy and difficult to transportβan important factor when considering lunar mining. Caterpillar trucks and excavators, used in Earth-based mines like Tellnes, would require 40 Saturn V rocket launches to bring their 2,500 tons of machinery to the Moon.
Powering the Equipment
Once the equipment is on the Moon, the next obstacle is powering it. Traditional diesel engines used on Earth cannot function in the Moonβs airless environment. Researchers suggest using a combination of solar energy and nuclear power to meet the required 11 MW of energy. However, solar panels would need to cover large areas, and nuclear reactors would add to the already enormous weight.
Table 1: Comparison of Earth vs. Moon Mining Operations
While extracting titanium on the Moon may not be immediately economically viable, thereβs another significant benefitβoxygen production. Ilmenite can be broken down to release oxygen, which is essential for everything from rocket fuel to breathable air in future lunar bases. This means that lunar mining may initially focus on oxygen extraction, with titanium being a valuable byproduct.
Technological and Economic Considerations
One of the biggest challenges is the development of technology capable of operating in lunar conditions. Machines will need to withstand extreme temperature fluctuations and operate in a low-gravity, airless environment. Advancements in robotics and autonomous mining systems are expected to play a crucial role.
Economic Viability
At present, the cost of extracting titanium from the Moon is too high for it to be an attractive option for Earth-based industries. However, as space exploration expands, there may be growing demand for lunar materials to support missions on the Moon, Mars, and beyond.
Although lunar titanium mining may not be economically practical right now, advancements in technology over the next two decades could change this. The real game-changer may be the extraction of oxygen from ilmenite, which would have immediate applications for space missions and future lunar bases. As NASAβs Artemis program and private ventures like SpaceX push forward, lunar mining could evolve from theoretical to practical.
Space Elevators and the Queen of the Asteroid Belt: A New Era in Resource Extraction
Space elevators could revolutionize the way humans access resources in space, especially on smaller celestial bodies like Ceres. Unlike Earth, where building a space elevator is technically impossible for now, smaller worlds offer unique opportunities to create such infrastructure with existing technology. This could lead to more efficient space travel and resource extraction, potentially launching a new era of exploration and economic growth in the asteroid belt.
Summary
Space elevators are designed to make space access easier, but Earthβs gravity and materials constraints make them currently infeasible.
On smaller celestial bodies like Ceres, building a space elevator becomes technically possible with existing technologies.
Space elevators have three main components: anchor, tether, and counterweight. The weak gravity on Ceres makes the construction of these components feasible.
Ceres’ surface, made of clay, offers a strong foundation for anchoring the elevator, withstanding forces of around 300N.
Carbon nanotubes, a potential material for tethers, are currently the best option for constructing the elevator on Ceres.
space elevators could serve as a launch platform for asteroid mining and water extraction, crucial for both fuel and life support systems in space missions.
The cost estimate for building a space elevator on Ceres is about $5.2 billion, making it a massive yet potentially revolutionary project.
Though the concept remains theoretical, the development of space elevator technology is slowly advancing, with more research and experimentation in the field.
Space elevators could help reduce reliance on traditional rocket launches and pave the way for more sustainable space exploration.
The Vision of Space Elevators on Earth and Beyond
space elevators have long been a dream for space enthusiasts, holding the promise of revolutionizing space access. Instead of burning fuel to break free from Earth’s gravity, a space elevator could provide a direct line to orbit. Unfortunately, the idea remains science fiction when it comes to Earth. The gravity is too strong, and the materials that would allow for a safe, functional elevator don’t exist yet. However,Β thereβs a different story when it comes to smaller celestial bodies. One such location is Ceres, the Queen of the Asteroid Belt.
Ceres, the largest object in the asteroid belt, provides a unique setting for constructing a space elevator. Unlike Earth, Ceres’ lower gravity and available resources could make this futuristic infrastructure feasible. But what exactly would it take to make a space elevator on Ceres a reality, and why would anyone want to build it there in the first place?
Components of a Space Elevator
Every space elevator requires three essential parts:
Anchor: The point where the elevator connects to the celestial body.
Tether: The long, strong cable connecting the anchor to the counterweight.
Counterweight: The mass at the end of the tether that stabilizes the system.
On Ceres, each of these components has unique considerations, but the challenges are more manageable than on Earth.
The Anchor
Anchoring a space elevator on Ceres is significantly easier than on Earth. The surface of Ceres is primarily composed of clay, a material relatively good for anchoring. Since Ceres has less mass than Earth, the forces exerted on the anchor are lower, around 300N (newtons). This is much less than what would be required on Earth, making asteroid anchoring technology, which has already been used successfully on other missions, a viable option here.
In fact, research suggests that the technology exists today to create anchors that can withstand up to 500N of force, meaning that building an anchor on Ceres would not pose much of a technical hurdle.
The Tether
The tether is the heart of any space elevator, and this is where Earth’s dreams break down. No known material can handle the immense stress and strain a tether would experience when tied to Earth. However, carbon nanotubes are a strong candidate for space elevators on Ceres.
Carbon nanotubes have an exceptional strength-to-weight ratio, which makes them the best known option for a space elevator tether. As this study highlights, while the tether for Ceres would still need more technological development, the idea is much closer to becoming a reality in space environments with lower gravity.
However, even with carbon nanotubes, the challenge of producing long, continuous strands remains. This is a limitation that needs to be overcome before we can make a functional space elevator on Ceres. Still, as technologies improve, this hurdle could be cleared in the not-too-distant future.
The Counterweight
The counterweight is perhaps the simplest part of the space elevator design. A big mass at the end of the tether provides the necessary balance to keep the system stable. On Ceres, the required mass would depend on the length of the tether. A heavier counterweight allows for a shorter tether, while a lighter counterweight would require a longer tether. This tradeoff allows flexibility in the design process.
Why Build a Space Elevator on Ceres?
Now that we know itβs technically possible, the next question is: Why build a space elevator on Ceres? The answer lies in the strategic importance of Ceres in the asteroid belt. With its abundance of water and its central location, Ceres offers unique advantages.
Water Extraction and Resource Mining
One of the biggest draws to Ceres is its proximity to water. Ceres has a vast supply of water stored beneath its surface. This water could be used for drinking, as a component of biological systems, or converted into hydrogen and oxygen for rocket fuel. This makes Ceres a valuable hub for both space exploration and potential colonization efforts.
By using a space elevator to launch materials from Ceres, we could access other valuable resources in the asteroid belt, making it a central point for future mining operations. The asteroid belt holds a wealth of metals and other materials that could be vital to industries back on Earth or in space colonies.
Gravity Assist for Interplanetary Travel
Another advantage of Ceres is its location in the solar system. Using a gravity assist from Jupiter, space travelers could send materials back to Earth or other destinations much more efficiently. This could dramatically reduce the cost of transporting resources across the solar system.
The Cost of a Space Elevator on Ceres
No large infrastructure project is cheap, and a space elevator on Ceres is no exception. The estimated cost is around $5.2 billion. While this is a huge sum, itβs within the realm of possibility for large-scale space exploration budgets. As this Universe Today article points out, smaller tests of space elevator technology are already underway, and with more investment, the technology could be scaled up for Ceres.
This figure, $5.2 billion, may seem like a lot, but itβs important to put it into perspective. Large space missions, such as NASAβs Artemis program or the James Webb Space Telescope, have similarly hefty price tags. If the benefits of asteroid mining and water extraction pan out, the long-term return on investment could far outweigh the initial cost.
The Future of Space Elevators
For now, space elevators remain largely theoretical, but there are signs that the technology is moving forward. As Isaac Arthur explains in his discussion of space elevators, while the concept might be difficult to implement on Earth, places like Ceres present more feasible options. As more nations and private companies get involved in space exploration, the economics of space elevators could shift, making them a more viable investment.
Even if space elevators donβt become common in the next decade, their development will likely continue to improve. This might start with smaller, more localized systems, like those proposed for lunar exploration or asteroid mining, before eventually leading to the grander vision of elevators capable of launching missions deep into the solar system.

Space elevators give us an exciting look at the future of space exploration and resource gathering. Right now, the technology doesn’t work on Earth. However, smaller places in space, like the dwarf planet Ceres, could be a better option for building them. Ceres has weaker gravity compared to Earth. This lower gravity could allow current technology to make space elevators possible there. If built, these elevators could help in collecting resources and enabling travel between planets.

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 todayβs 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 Vehicleβs service module is larger and more powerful.
