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, ...
