The discussion revolves around the feasibility and economic viability of asteroid mining, particularly in light of recent funding announcements for companies like AstroForge. Participants explore the potential for extracting minerals from asteroids versus traditional mining on Earth, as well as the implications of such endeavors.
Participants generally express skepticism about the economic feasibility of asteroid mining, with multiple competing views on its practicality and potential returns. The discussion remains unresolved regarding the viability of asteroid mining as a source of minerals.
Participants highlight the high costs associated with space missions and the potential limitations of asteroid mining compared to traditional mining methods. There is uncertainty regarding the technological and economic challenges that may affect the success of asteroid mining ventures.
Last week AstroForge announced that it had closed a $13 million round of "seed plus" funding, which was led by Initialized Capital, with investments from Seven Seven Six, EarthRise, Aera VC, Liquid 2, and Soma. The company presently has seven employees, and this will allow that number to double. AstroForge is planning a launch in January 2023 of a small satellite to perform a refining demonstration in low Earth orbit. After that, the company is planning two more missions into deep space, and this funding will provide the runway to carry AstroForge that far.
"We don't need that much capital," Gialich said. The company plans to design spacecraft small enough to fly as part of rideshare launches. "We're going after this by bringing along a very, very small spacecraft to mine asteroids. So our first return mission is not going to return trillions of dollars. It's not going to return billions of dollars. It's going to return tens of millions of dollars."
Platinum is currently priced at $31,000 a kilogram, so the company is likely talking about bringing hundreds of kilograms of platinum back to Earth, or less. To be clear, this is still an enormous leap—NASA's OSIRIS-Rex mission is believed to be returning about 1 kg of unrefined material from the surface of an asteroid at a mission cost of about $800 million.
To do this, the company plans to build and launch what Gialich characterized as a "small" spacecraft to a near-Earth asteroid to extract regolith, refine that material, and send it back toward Earth on a ballistic trajectory. It will then fly into Earth's atmosphere with a small heat shield and land beneath a parachute. The goal is to build each of these satellites at a recurring cost of significantly less than $10 million.
