Asteroid mining tech is being tested in space in April by satellite construction company AstroForge. Rowan speaks with their co-founder to hear what they’re hoping to achieve, and discusses the company’s second mission planned for later this year, when they’ll be doing a flyby of a near-Earth asteroid to look for platinum.
