In Jules Verne’s 1865 novel From the Earth to the Moon, members of the fictitious Baltimore Gun Club, all disabled Civil War veterans, restlessly search for a new enemy to conquer. The Phase 1 winners are scheduled to be announced on August 13. The Challenge is currently in Phase 1, and while I can’t find any information on Phase 2, the fact that there’s a Phase 1 does imply that the winning team (or teams) might have the opportunity to further prove out their concept in additional challenge phases. It’s good to see that some testing has already been done on Earth to characterize how rocket plumes interact with a simulated icy lunar surface, but managing all the extra dust and rocks that will get blasted up along with the ice particles could be the biggest challenge here, especially for a system that has to excavate a lot of this stuff over a long period of time.įortunately, this is all part of what NASA will be evaluating through its Break the Ice Challenge. The concept video looks pretty awesome, but there’s certainly a lot of work that needs to be done to prove the rocket mining system out, especially once you get past the component level. It’s a little bit tricky to get a sense of how well a concept like this might work. And Lunar Outpost were some of the folks behind the MOXIE system on the Perseverance Mars rover. Honeybee Robotics has developed hardware for a variety of missions, including Mars missions.
Masten has built a variety of operational rocket systems, and is developing some creative and useful ideas with NASA funding like rockets that can build their own landing pads as they land. The stored water can be electrolyzed as needed into oxygen and hydrogen utilizing solar energy to continue powering the rocket engine for more than 5 years of water excavation! This system would also allow us to rapidly excavate desiccated regolith layers that can be collected and used to develop additively manufactured structures.ĭespite the horrific backronym (it couldn’t be a space mission without one, right?) the solid team behind this rocket mining system makes me think that it’s not quite as crazy as it sounds. Our system doesn’t require heavy machinery or ongoing maintenance. And most importantly, it’s scalable and cost effective. Unlike traditional mechanical excavators, the rocket mining approach would allow us to access frozen volatiles around boulders, breccia, basalt, and other obstacles. During this process, ejecta from multiple rocket firings blasts up into the dome and gets funneled through a vacuum-like system that separates ice particles from the remaining dust and transports it into storage containers. It utilizes a 100 lbf rocket engine under a pressurized dome to enable deep cratering more than 2 meters below the lunar surface.
ROCKETSHIP BLUEPRINTS SERIES
This method disrupts lunar soil with a series of rocket plumes that fluidize ice regolith by exposing it to direct convective heating. (It’s what they call, brace yourself, their Resource Ore Concentrator using Kinetic Energy Targeted Mining-ROCKET M.) The agency has launched a competition to solve this lunar ice mining challenge, and one of competitors thinks they can do it with a big robot, some powerful vacuums, and a rocket engine used like a drilling system. The extraction and purification of this dirty lunar ice is not an easy problem, and NASA is interested in creative solutions that can scale. If that water ice can be extracted, it can be turned into breathable oxygen, rocket fuel, or water for thirsty astronauts.
This is certainly the case for Mars, and it’s likely also the case for the Moon-even though the Moon is not all that far away (in the context of the solar system). It’s stupendously inefficient to send stuff there, especially when that stuff is, with a little bit of effort, available on the Moon already.Ī mix of dust, rocks, and significant concentrations of water ice can be found inside permanently shaded lunar craters at the Moon’s south pole. Realistically, in-situ resource utilization seems like the only way of sustaining human presence outside of low Earth orbit.
