Paragon Space Development Corporation, a subcontractor for Dynetics which is one of the three companies NASA has selected to begin work on designs for human lunar landers, was just awarded a Small Business Innovation Research (SBIR) Phase I grant to develop its ISRU Collector of Ice in a Cold Lunar Environment or ICICLE. The system will use a cold trap for collecting and purifying water from ice mining the permanently shadowed regions of the lunar poles. The purification and collection of lunar water is a critical step in generating in-situ propellant, breathable oxygen, and potable water for space settlements and the cislunar economy.
In a recent thread on Twitter referring to a forthcoming paper, Kevin M. Cannon calculates the optimum path for rover access down into the cold traps in lunar craters at the Moon’s poles. The entire dataset including an ice prospecting guide is available on Cannon’s website which is now linked on our In Situ Resource Utilization page

NASA’s Jet Propulsion Laboratory is developing a CubeSat that will utilize near-infrared lasers and an onboard spectrometer to prospect for ice in the permanently shadowed craters at the Moon’s south pole. The suitcase size spacecraft will inform future Artemis missions on where to begin in-situ resource utilization of this valuable commodity for space settlement
This artist’s concept shows the Lunar Flashlight spacecraft, a six-unit CubeSat designed to search for ice on the Moon’s surface using special lasers. The spacecraft will use its near-infrared lasers to shine light into shaded polar regions on the Moon, while an onboard reflectometer will measure surface reflection and composition.

Joel Sercel of Trans Astronautica Corporation was recently awarded a Phase II NIAC grant for a Lunar Polar Mining Outpost (LPMO) that promises to greatly reduce the cost of commercializing propellant production on the Moon. The system utilizes two patented innovative concepts for generating power and processing regolith. The first invention is a several meters tall solar reflector tower called a Sun Flower™ to gather sunlight at the permanently illuminated areas near the poles and reflect it down to megawatt level solar arrays near the outpost. The second concept called Radiant Gas Dynamic (RGD) mining combines microwave and infrared radiation to sublimate ice out from the regolith for storage in cryotraps on electric powered rovers. The outpost elements are designed to be delivered to the lunar surface using Blue Origin’s New Glenn rocket and Blue Moon lander.
Sercel states that “…LGMO promises to vastly reduce the cost of establishing and maintaining a sizable lunar polar outpost that can serve first as a field station for NASA astronauts exploring the Moon, and then as the beachhead for American lunar industrialization, starting with fulfilling commercial plans for a lunar hotel for tourists”
