Asteroid 2022 OB5 Spins Too Fast For Current Prospectors Highlighting the Divide Between "Accessible" and "Exploitable"

Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility. But in practice, it is certainly not that simple, and a new paper from some Spanish researchers, available in pre-print form on arXiv, showcases one of the reasons why - many small asteroids are spinning ridiculously fast.
