Space Mining


Our multipurpose excavator integrates a small percussive shovel head excavator, with dual bucketladders and bucketwheels in continuous operation. Our two wheel bucket rover uses a dragline crane for deep craters and lava tube excavation.

Our efficient Solid Oxide water electrolysis cell can generate 10,000 kg/day of hydrogen and oxygen gas. Utility grid model scaled to a 10 MW fuel cell stack / 4,534 kilos a day operating on Earth at $2.47 /kg.  Fuel, Energy, Air, Heat, and Water.

Our fuel cell generation of wholesale electricity offered at near-term LMP  averages $20 /kg and $60 /kg during peak season,  and real-term on-demand pricing average $80 /kg to $200 /kg per unit,  10 units generates 100MW, from seawater!

Man's Next Step

We stand on the cusp of a new revolution, one where early innovators of commercial space will capitalize on new technological advances, meet material demands to create environmental sustainability, and build spacecraft to transport populations into orbit that drive the exploration, exploitation, and habitation of our solar system. 

Our greatest limitations to advancing into space exploration are the high cost of  launching heavy essential materials and heavy payloads from Earth. (Currently $22,000 /kg) The ability to extract raw materials from the Lunar surface such as water and iron, would form the base of this infrastructure and processing these resources at an advanced space exploration site into useful products such as propellants, breathable oxygen, and power system consumables is known as In-Situ Resource Utilization.

An ISRU system on the Moon, is the last roadblock in significantly increasing robotic and human exploration infrastructure, sustaining life, and opening vast opportunities in space.

The ability to extract or produce large amounts of oxygen and water in-situ could minimize the need to maintain closed life support air and water processing system cycles, change thermal properties and provide radiation protection of habitats, and would influence propellant selection to lunar orbital platforms as gateway for refueling depots and staging areas in traveling to Mars and deep space.  

Planetoid Mines provides the technological mining infrastructure to manage ISRU production, providing life essential resources of fuel, water, oxygen, and other mined resources, to cislunar refueling depots, lunar gateway outpost and orbiting satellites.

Next Steps...

We are launching to the Moon in 2022, but first we will use seawater to produce hydrogen and rocket fuels on Earth.
