Rocket mining robot built to collect water from the Moon’s crust

Aerospace manufacturer Masten Space Systems has built a roaming rover capable of mining water from the moon’s crust using rocket blasts.

We’re reportedly closer to achieving one of NASA Artemis’ key goals – establishing a human presence on the Moon within the next three years.

Case in point, with the staggering costs of shipping supplies from Earth, how will NASA create a water network on the lunar surface for drinking, fuel production, and growing food?

Apparently, it’s a lot trickier than blasting hydraulic mining astronauts into outer space.

As with most of its inter-planetary missions, NASA is outsourcing ideas and tech prototypes from some of the world’s savviest engineering companies.

Specifically, the brief dubbed ‘Break the Ice’ is calling for sophisticated rovers to travel to shadowed areas of the lunar south pole, where deposits of permafrost ice lay within craters 3.5 meters deep.

Once mined, transported to a basepoint, and processed, this ice could provide all the water needed to start building conditions on the Moon for lengthy human expeditions. That’s 170 million lbs, to be precise.

Of course, for this to happen the rover in question will need onboard mining capabilities itself.

With that in mind, the most promising entrant thus far is a 2500lb solar powered machine called ‘Rocket M,’ developed by aerospace manufacturer Masten Space Systems.

Infeasible as it sounds on paper, the vehicle is able to break up large clumps of ice quickly through firing precise downward facing rocket pulses.

Rolling across the surface at 2.14 mph, the Rocket M will navigate its way to pre-selected mining spots where its rockets use convective heating to pierce the surface up to 2 meters deep.

Thankfully, unlike traditional rockets, nuclear energy isn’t used to provide thrust for these rockets. Instead, the system runs on oxygen and hydrogen electrolysed from water, meaning it effectively mines its own fuel. Nice.

Once mined, icy ore is hoovered at close range into the rover where it is separated from sediment using sophisticated magnets. The excess then passes through a second filter called an electrostatic sorter, which uses cold plates to capture any remnants of water vapour still hidden in the mix.

Sounds complicated right? Yet the process takes all of 5 to 10 minutes.

Having tested the system thoroughly on ‘simulated lunar ice’ – which we presume is likely just ice – Rocket M’s creators assert that up to 12 craters can be mined per day. At around 220 lbs of icer per crater, that works out at 426 tons recovered in a single year.

As automated assistants go, even in 2021, it’s pretty damn efficient.

Because of its light weight and mobility, Rocket M is able to navigate around boulders, breccia, basalt, and any other mysterious obstacles it may encounter along the way.

In terms of its uses, it could also prove to be super versatile. Masten Space Systems claims the machine can mine regular land for building materials if required to do so. Elon Musk will be picturing that mansion and Earth view pool right about now – all paid for in Doge.

Nuts as a rocket firing rover sounds, granted, the Rocket M is comfortably the most effective solution we’ve seen to date in excavating water from the Moon’s surface. Again, it’s unanimous among those in the know that sending water from here simply isn’t feasible.

If the Rocket M wins NASA’s challenge, which looks likely at this stage, its rovers could be altered for similar purposes on Mars, enabling exploration about our cosmos all year round.

Only time will tell to see if the Rocket M performs as well in the wild as it sounds in theory.
