There's an asteroid out there worth $100,000 quadrillion. Where is it?

While asteroids are rich sources of precious and valuable materials, scientists still haven't fully committed to mining them.On Oct. 13, 2023, NASA launched a mission to 16 Psyche, a large, metal-rich asteroid about six years  away, to learn more about how planetary interiors form.

The asteroid has a jaw-dropping estimated monetary value: $100,000 quadrillion. That's because 16 Psyche is a literal goldmine, packed with rare elements essential to cars and electronics, like platinum and palladium.

To explore — and perhaps settle — space, we'll need extraterrestrial sources of materials. Companies such as AstroForge and TransAstra are already looking into building mines on asteroids like Psyche. But how close are we  to mining them and reaping their cosmic treasures? Technologically speaking, we're pretty close, said Philip Metzger, a planetary physicist at the University of Central Florida. The only difference between mining on an asteroid versus on Earth is the need for equipment that can withstand low-gravity, high-radiation conditions. The equipment also needs to be able to function autonomously — it could take 20 minutes or more for a radio wave with instructions to reach an asteroid, especially if it's on the other side of the sun.All that technology has already been developed and tested in a laboratory setting, but it's not quite ready for implementation, Metzger said. On NASA's Technology Readiness Levels scale, which ranges from 1 to 9, our current equipment for space mining sits between a 3 and a 5.

"The technologies need to be advanced — about a 6 to 7 — before we're ready to start building a flight mission," Metzger told Live Science. "What's lacking right now is funding." If all that money poured in now, we might see small-scale asteroid mining in five years, Metzger added.


Any progress toward asteroid mining will likely come from the private sector, said Kevin Cannon, an assistant professor of geology and geological engineering at the Colorado School of Mines' Space Resources Program. But there's at least one potential obstacle: explaining to potential investors why we should mine asteroids in the first place.

It's a fair question. Bringing materials back to Earth is "economically dubious," Cannon told Live Science. It would be extraordinarily expensive to do so, and platinum group metals are actually declining in price. But asteroids might be an important source of material for development in space, he added.

"So, for example, if we extracted water from [a] water-rich asteroid, we could split that apart into hydrogen and oxygen, and use that as rocket propellant to refuel spacecraft," Cannon said. Metals mined from asteroids, meanwhile, could be transformed into large structures in space.

That raises another question: Why not just mine the moon? All of the materials we'd want to mine from asteroids also exist there, albeit in lower concentrations. And, of course, it's much closer.

The benefit of the moon is, it's just days away, Cannon said. "Even these near-Earth asteroids that people talk about, if you consider how long it takes to wait for the orbits [between the asteroids and Earth] to line up, which you need to get back, it's many hundreds of days." Psyche, with its $100,000 quadrillion bounty, will take years to reach, with first contact estimated to occur in 2029.

Even if we aren't ready to mine asteroids, scientists are still interested in exploring thesspace rocks. Less than a month before the Psyche mission launched, NASA's OSIRIS-REx spacecraft returned from its mission to the asteroid Bennu, with samples in tow. In 2020, the Japanese spacecraft Hayabusa2 returned with samples from the asteroid Ryugu, before taking off to explore two other asteroids: 2001 CC21 and 1998 KY26. And in October, the European Space Agency will launch a mission to the asteroid Hera.

None of these missions are focused explicitly on mining. The research goals of both OSIRIS-REx and Hayabusa2 included developing a better understanding of ancient Earth's geology and chemistry, while Hera is investigating planetary defense technology.

"There's no magic technology that we have to invent to mine asteroids. We have the technology," Cannon said. "It's a matter of having the will to do so and putting the capital towards doing it."
