New research reveals that asteroid 2022 OB5 is an "ultra-fast rotator," spinning once every 1.542 minutes. This discovery, made using the HiPERCAM instrument, suggests that many small, accessible asteroids exhibit similar rapid rotation rates.
For space mining ventures, this presents a significant challenge. The high centrifugal acceleration at the asteroid's equator could make it extremely difficult for spacecraft to land or anchor, potentially being ejected back into space. While companies like Astroforge claim to have solutions, the findings underscore the critical need for detailed physical characterization before undertaking resource extraction missions.
