Karman+ is developing an autonomous spacecraft designed to travel to asteroids, mine regolith, extract water for orbital refueling, and ultimately enable extraction of rarer materials to support space manufacturing. The team is building hardware and software using off‑the‑shelf components and plans its first launch in 2027. Karman+ projects missions could be run for around $10 million each, compared with past asteroid missions that have cost upward of $1 billion. The company says the refueling market opportunity could be worth single‑digit billions of dollars per year. The spacecraft has not yet been completed or tested, and Karman+ anticipates it will need to raise additional funding as it moves toward launch. Co‑founders include CEO Teun van den Dries and mission architect Daynan Crull; van den Dries previously co‑founded GeoPhy, which was acquired for $290 million in 2022. The company is based in Denver, Colorado and has roots in the Netherlands.
