Karman+
|
Asteroid mining has lived at the intersection of scientific research and popular culture for decades, with as many academic papers published as there are books, TV shows and movies about it. Access to resources, with its finite nature and disparate distribution of resources, plays an essential part in the geopolitical web of power and wealth. Ithas defined economic growth to such an extent that we have been using them as primary demarcation lines and identifiers in our history, from the stone to bronze and iron age to our current silicon age. But our resources-driven growth faces a massive existential challenge, with climate change, ecosystem degradation and resource depletion demanding a complete reset. Humanity needs to shift global transportation, manufacturing, construction and energy onto a sustainable path. Expanding beyond the Kármán line is where we believe transformative future growth and innovation will be found. Recent missions by NASA (OSIRIS-REx & DART) and JAXA (Hayabusa2) have firmly pushed the idea of using space resources from academic research into commercial opportunity. We believe the Regolith Age, powered by abundant space resources, is an inevitability that we can accelerate. | $20M / Seed / Feb 19, 2025 | |
