CRITICAL MINERALS

Critical Minerals

Critical Minerals Required for Deep Space Missions

Deep Space Missions, which involve exploration beyond Earth's Orbit—such as journeys to the Moon, Mars, asteroids, or further—depend on Advanced Technologies that must function reliably in extreme conditions like High Radiation, Temperature Fluctuations, and the Vacuum of Space. These technologies, including Spacecraft, scientific instruments, life support systems, and propulsion units, rely on a range of critical minerals. These minerals are essential due to their unique physical and chemical properties, such as strength, conductivity, heat resistance, and lightweight characteristics. Below is an overview of the key categories of critical minerals and their roles in enabling deep space exploration.

1. Structural and Lightweight Metals

Spacecraft and habitats require materials that are strong yet lightweight to minimize launch costs and ensure durability. Key minerals in this category include:

• Aluminum: Widely used in spacecraft frames and panels for its low density and high strength, making it ideal for structural components.

• Titanium: Valued for its exceptional strength-to-weight ratio and resistance to corrosion, often used in critical structural parts and engine components.

• Magnesium: Incorporated into lightweight alloys to reduce mass while maintaining structural integrity.

These metals form the backbone of spacecraft, rovers, and other equipment, allowing them to endure the mechanical stresses of launch and deep space travel.

2. Electronics and Sensor Materials

Deep space missions rely heavily on sophisticated electronics for navigation, communication, and scientific data collection. The following minerals are indispensable:

• Silicon: The foundation of semiconductors, used in computers, sensors, and communication devices that control mission operations.

• Gallium: Employed in solar cells (e.g., gallium arsenide) and optoelectronic devices for efficient power generation and data transmission.

• Rare Earth Elements (REEs): A group of 17 elements (e.g., neodymium, dysprosium) critical for powerful magnets, lasers, and phosphors in sensors and communication systems.

These materials ensure that spacecraft can process data, maintain contact with Earth, and conduct scientific experiments in remote environments.

3. Energy Storage and Generation Materials

Powering deep space missions requires reliable energy sources, especially where solar energy may be limited. Key minerals include:

• Lithium: A cornerstone of high-energy-density batteries, essential for storing power for spacecraft and rovers.

• Cobalt and Nickel: Used in battery cathodes to improve energy capacity and stability, supporting long-duration missions.

• Platinum Group Metals (e.g., Platinum, Palladium): Critical for catalysts in fuel cells and other energy conversion systems.

• Uranium and Plutonium: Utilized in radioisotope thermoelectric generators (RTGs) to provide consistent power for missions far from the Sun, such as those to the outer planets.

These minerals enable energy solutions that sustain spacecraft operations over vast distances and extended timeframes.

4. Propulsion and Thermal Management Materials

Propulsion systems and thermal protection are vital for navigating and surviving the harsh conditions of space. Relevant minerals include:

• Nickel and Chromium: Found in superalloys for rocket engines and components that must withstand high temperatures and stresses.

• Carbon and Boron: Used in composite materials (e.g., carbon fiber, boron nitride) for lightweight thermal shields and structural reinforcement.

• Tungsten: Prized for its high melting point, potentially used in applications requiring extreme heat resistance, such as nozzles or shielding.

These materials ensure that spacecraft can travel efficiently and protect sensitive systems from thermal extremes.

5. Life Support and Environmental System Materials

For crewed missions or long-term exploration, life support systems are crucial to sustain human life. Key materials include:

• Zeolites: Naturally occurring or synthetic minerals used in air and water purification systems to remove impurities.

• Activated Carbon: Employed in filters to recycle air and water, maintaining a habitable environment.

• Catalysts (e.g., Platinum, Palladium): Facilitate chemical reactions in life support systems, such as oxygen generation or carbon dioxide removal.

These materials are vital for recycling resources and ensuring a stable environment for astronauts during extended missions.

Why These Minerals Are Critical

The minerals listed above are deemed "critical" for deep space missions because they possess properties that are difficult to replicate with substitutes and are indispensable for mission success. For example, titanium’s strength-to-weight ratio is unmatched for structural applications, while rare earth elements provide magnetic properties essential for compact, high-performance electronics. Additionally, the extreme conditions of deep space—radiation, vacuum, and temperature swings—demand materials that can perform reliably without degradation.

Conclusion

The success of deep space missions hinges on a suite of critical minerals that enable the construction and operation of spacecraft, instruments, and life support systems. These include structural metals like aluminum, titanium, and magnesium; electronics materials such as silicon, gallium, and rare earth elements; energy-related minerals like lithium, cobalt, nickel, platinum, uranium, and plutonium; propulsion and thermal materials including nickel, chromium, carbon, boron, and tungsten; and life support materials like zeolites, activated carbon, and catalysts. As humanity pushes further into the cosmos, securing access to these minerals will remain a priority to support the technological backbone of space exploration.

Critical Minerals are minerals that are vital for Humanity, Energy, Defense, Consumer Goods, Manufacturing, Pharmaceutical and many more sectors.

The USGS National Map of Surficial Mineralogy can help identify minerals in the United States. The USGS also has a program called Earth MRI that aims to improve the country's knowledge of critical mineral resources. 

• The U.S. Geological Survey (USGS) published a list of 50 Critical Minerals in 2022.

Aggregate and Industrial Minerals

Location and volume of limestone and sand and gravel aggregate reserves in Texas.

Due to the current population growth and rapid urbanization, the use of construction materials has increased significantly. This recent boom in construction has also significantly increased the demand for aggregate. To meet the demand, new sources of aggregate are being explored and new aggregate quarries are being developed.

Aggregate is a mostly nonrenewable natural resource, but research is being conducted with an emphasis on using aggregates in a more sustainable manner. Recycled aggregates, industry waste, and new sources of aggregates are being used in the construction industry. However, alternate sources of aggregates represent only a small percentage of the total aggregate need. As a result, reserves of natural aggregates are being depleted rapidly in some areas of the state. According to the U.S. Geological Survey, 30% of aggregate is used for highway construction. Although natural aggregate sources are widely distributed throughout Texas, they are not universally suitable for consumption. In many cases the local aggregate sources do not meet the required organizational aggregate specifications (e.g. TxDOT requirements for different types of road construction). Rapid expansion of residential, industrial, and commercial areas and increasingly stringent environmental regulations have begun limiting aggregate mining, particularly in and around urban areas. In areas where acceptable quality aggregate is not locally available, it may become necessary to improve the quality of local aggregates, to import aggregates from outside sources, or to use artificial aggregates instead of local aggregates. Therefore, it is important for research to study these materials, how and where we use them, and develop policies for aggregate use and strategies for ensuring adequate future aggregate supplies. Where end use applications for aggregates overlap with the large Texas energy industry base, research collaborations exist with CEE and other Bureau programs for trends, activity and future developments.

Research topics include:

• Resource analysis

  • Geologic mapping of aggregate resources

  • Mapping geologic setting of the aggregate used in Texas (including surrounding states and Mexico)

  • Quantifying aggregate reserve and overburden

  • Calculating the volume and tonnage of aggregate reserve, calculate overburden volume that will be removed to extract the resource, create an economic mineral resource model showing economics of increasing depth, expanding horizontally, and permitting costs and restrictions for mining below the ground water level and near ground water bodies

  • Mapping favorability for extraction

  • Mapping proximity to end users, transportation infrastructure, metropolitan areas, and other characteristics like resource quality and stripping ratio to build a combined map of new favorable mining sites in Texas

• Application

  • Identifying favorable locations for aggregate use (applied aggregate specifications)

  • Mapping regions by aggregate specification and best usage principles

  • Exploring the characteristics of aggregate for construction, concrete, pavement and other engineered materials

  • Exploring the behavior of recycled and blended aggregate products for sustainability

• Logistics and transportation economics

  • Evaluating favorable modes of transportation

  • Creating network datasets for all modes of transportation infrastructure in Texas, modeling costs of transportation, and calculating optimum routes using one or more modes of transportation

  • Identifying new infrastructure development opportunities

  • Evaluating impact of new transport infrastructure like rail roads, highways, freight transfer stations etc. near mining sites and explore prospects and potential benefits for new infrastructure

• Other Industrial Minerals in Texas currently being researched:

  • Sulfur

  • Gypsum

  • Cement

  • Salt

  • Caliche

  • Clay

  • Zeolites

  • Dimension stone (granite, limestone, gabbro, etc.)
