SYSTEM FOR EXTRACTING WATER FROM LUNAR REGOLITH AND ASSOCIATED METHOD
20250237144 · 2025-07-24 ·

The system extracts water from lunar regolith and includes a regolith intake having a digging bucket that collects lunar regolith soil and a gravel separator that separates and discharges gravel and passes a mixture of ice-regolith powder having ice grains that are about 10-100 microns along the conveyor. A pneumatic separator receives the ice-regolith powder and pneumatically splits the ice-regolith powder into streams of different sized lithic fragments and ice particles per the ratio of inertial force and aerodynamic drag force of the lithic fragments and ice particles. Each split stream may include a magnetic separator that separates further the magnetic and paramagnetic lithic fragments from ice particles to discharge up to 80 percent of lithic fragments to slag.

Lunar water collection device

Techniques and systems extract water from lunar regolith using microwave radiation and may also produce fuel from the extracted water. The system can distill the extracted water to remove impurities before electrolyzing the purified water into oxygen and hydrogen gases, which may then be cooled to form liquid oxygen and liquid hydrogen. A portion of the system may reside on a lunar landing module. Another portion of the system may be affixed to a robotic arm that is extendable from the lunar landing module. This portion of the system includes a water extraction unit, comprising a cone used as a cold trap. The cone may include cooling channels to keep the temperature of the smooth inner surface of the cone cold enough to trap particles of frost that attach to the inner surface. The frost is then scraped from the inner surface and collected.

Heat recovery arrangement

Described herein are embodiments directed to a heat recovery arrangement for collecting vaporized gas trapped in regolith. The heat recovery arrangement generally comprising a rover that carries heat recovery elements that cooperate with a primary heat source. The heat recovery elements include a preheat contact element that preheats a region of regolith before the region is brought to high heat by the primary heat source. As the rover moves forward, the preheat contact element receives heat collected from the high heat region via a heat recovery sled that moves in contact with the high heat region. Heat is transferred between the heat recovery sled and the preheat contact element via a heat transfer medium that circulates through the heat recovery sled and preheat contact element.

Compound parabolic concentrator arrangement

Described herein are embodiments directed to collecting vaporize gas via a CPC arrangement. The CPC arrangement generally comprises a transporter that carries around a cover with one or more cryogenically cooled plates (or some other cryogenically cooled surface) therein. A plurality of CPCs dispersed on the transporter each have a concave reflective bowl that captures and directs sunlight through a fiberoptic cable where the sunlight is focused on regolith in an internal environment defined within the cover when resting atop the regolith. The focused sunlight heats the regolith and liberates the gas from the regolith, which is trapped in the internal environment. The gas in the internal environment condenses on the cooled plates where it can be collected and processed.

Electrostatic filtration arrangement

Described is a particle filtration system that protects a gas segregation region from lunar regolith dust by using an electrostatic filter arrangement. An ionizing element (screen or bar, for example) generates one or more electron curtains that charge neutral dust particles, which are then drawn to paired conductive plates via electrostatic attraction. The system operates efficiently in vacuum conditions, leveraging field emission from sharp triangular apexes of the ionizing element/s to create high-density electron streams. A final-stage ULPA mesh filter captures any remaining particles, ensuring only gas enters the gas segregation region. This design enhances dust mitigation, improves gas collection efficiency, and protects sensitive components in harsh extraterrestrial environments.
