Autonomous Spacecraft

One of the fundamental technologies enabling space mining is the use of autonomous spacecraft. These spacecraft are designed to operate independently, without human intervention, which is crucial for missions that take place millions of miles away from Earth. The autonomous systems on these spacecraft include:

Navigation Systems: Advanced navigation systems use a combination of star tracking, inertial measurement units (IMUs), and ground-based tracking to accurately determine the spacecraft’s position and trajectory. This precision is essential for reaching and landing on target asteroids.
Propulsion Systems: High-efficiency propulsion systems, such as ion thrusters and solar-electric propulsion, provide the necessary thrust for long-duration missions. These systems are designed to maximize fuel efficiency, allowing spacecraft to travel farther and carry out extended operations.
Onboard AI: Artificial intelligence (AI) is integrated into the spacecraft’s systems to enable real-time decision-making and autonomous operations. AI algorithms process data from sensors and cameras to identify optimal landing sites, avoid obstacles, and manage the extraction process.

Robotic Mining Systems

Robotic mining systems are at the heart of Tengri’s space mining operations. These systems are designed to perform the physical tasks of mining in the harsh environment of space. Key components of our robotic mining systems include:

Mining Robots: Specialized robots equipped with drills, scoops, and cutting tools are deployed to extract material from asteroids. These robots are capable of operating in low-gravity conditions and can be remotely controlled or operate autonomously.
Material Handling Systems: Once material is extracted, it needs to be transported and processed. Our material handling systems include conveyor belts, robotic arms, and storage containers designed to function in microgravity. These systems ensure that extracted material is efficiently moved from the mining site to processing units.
Surface Mobility: Mobility solutions such as robotic rovers and hoppers allow our mining robots to navigate the rugged terrain of asteroids. These systems are designed to handle the low-gravity environment and can traverse rocky surfaces, craters, and slopes to reach mining targets.

In-Situ Resource Utilization (ISRU)

In-Situ Resource Utilization (ISRU) is a critical technology that allows us to process and utilize resources directly on the asteroid, reducing the need to transport raw materials back to Earth. ISRU technologies being developed by Tengri include:

Regolith Processing: The extraction of valuable minerals from regolith (the loose, fragmented material covering the surface of asteroids) is a key focus of our ISRU efforts. Techniques such as heating, electrolysis, and chemical processing are used to separate metals and other valuable elements from regolith.
Water Extraction: Water is a vital resource for space missions, and many asteroids contain significant amounts of water ice. Our water extraction systems use thermal and microwave techniques to melt and capture water from the asteroid’s surface. This water can be used for life support, radiation shielding, and as a component of rocket fuel.
Manufacturing and Construction: ISRU technologies also include the ability to manufacture tools, components, and structures using materials found on asteroids. Additive manufacturing (3D printing) and other fabrication techniques enable the creation of parts and equipment directly in space, reducing the need for resupply missions from Earth.

Plasma-Based Extraction

Plasma-based extraction is an innovative technology that utilizes plasma (a highly ionized gas) to break down and extract valuable minerals from asteroids. This method offers several advantages over traditional mining techniques:

High Efficiency: Plasma-based extraction is highly efficient at breaking down complex materials, allowing for the recovery of a wide range of elements, including rare earth metals, platinum group metals, and more.
Environmental Impact: The use of plasma reduces the need for chemical reagents and minimizes the generation of waste. This makes plasma-based extraction a more environmentally friendly option for space mining.
Adaptability: Plasma systems can be adapted to different types of materials and mining conditions. This flexibility allows us to target a variety of asteroids with different compositions.

Advanced Sensors and Instrumentation

Accurate data collection and analysis are essential for successful space mining operations. Tengri employs a range of advanced sensors and instrumentation to gather information about target asteroids and monitor mining activities:

Spectrometers: Spectrometers analyze the composition of asteroid surfaces by measuring the light reflected from them. This helps identify the presence of valuable minerals and guide mining efforts.
Radar and Lidar: These technologies are used to create detailed maps of asteroid surfaces, identifying features such as craters, ridges, and potential landing sites. Radar can penetrate the surface to reveal subsurface structures, while lidar provides high-resolution topographical data.
Thermal Imaging: Thermal cameras detect temperature variations on asteroid surfaces, which can indicate the presence of certain materials and provide insights into the asteroid’s structure.
Seismometers: Seismometers measure vibrations and seismic activity on asteroids. This data helps us understand the internal structure of asteroids and assess the stability of mining sites.

Communication Systems

Reliable communication is crucial for coordinating space mining operations and transmitting data back to Earth. Tengri’s communication systems include:

Deep Space Networks: We utilize existing deep space networks, such as NASA’s Deep Space Network (DSN), to maintain communication with our spacecraft. These networks provide high-bandwidth communication links over vast distances.
Relay Satellites: In some cases, relay satellites are deployed to enhance communication capabilities. These satellites orbit the asteroid or are positioned at strategic points to relay signals between the spacecraft and Earth.
Data Compression: Advanced data compression techniques are used to efficiently transmit large volumes of data, such as high-resolution images and sensor readings, over limited bandwidth connections.

Energy Systems

Sustaining mining operations in space requires reliable and efficient energy systems. Tengri employs a variety of energy solutions to power our spacecraft and mining equipment:

Solar Power: Solar panels are the primary source of energy for our spacecraft. These panels convert sunlight into electricity, providing a renewable and sustainable energy source. Solar arrays are designed to be lightweight and efficient, maximizing energy capture.
Battery Storage: Energy storage systems, such as lithium-ion batteries, store excess energy generated by solar panels. These batteries provide a stable power supply during periods when the spacecraft is not in direct sunlight, such as during eclipses or while operating on the dark side of an asteroid.
Radioisotope Thermoelectric Generators (RTGs): For missions requiring long-duration power supply, we use RTGs. These generators convert the heat released by the decay of radioactive isotopes into electricity, providing a reliable power source for years.

Safety and Sustainability Technologies

Ensuring the safety of our operations and minimizing environmental impact are paramount concerns for Tengri. Our R&D team has developed several technologies to address these challenges:

Radiation Protection: Space mining missions are exposed to high levels of cosmic radiation. Our spacecraft and equipment are designed with radiation shielding materials to protect electronic systems and ensure mission longevity.
Collision Avoidance: Autonomous navigation systems are equipped with collision avoidance algorithms to prevent impacts with other spacecraft or debris. This enhances the safety and reliability of our operations.
Environmental Monitoring: We employ sensors to monitor the environmental impact of our mining activities. These sensors track parameters such as dust generation, surface disruption, and potential contamination. By continuously monitoring these factors, we can implement mitigation measures to minimize our ecological footprint.
