SpaceX successfully landed their Super Heavy booster with precision, catching it using unique chopsticks. Vice President Bill Gerstenmaier claimed they had achieved a half-centimeter accuracy, sparking skepticism. An aerospace engineer questions this level of accuracy, citing errors from measurement methods, manufacturing tolerances, and thermal effects. However, they praise SpaceX’s achievement and explain the challenges of controlling a rocket’s position, orientation, and attitude. Ultimately, SpaceX’s ability to control the booster accurately is impressive, but information on the exact precision remains speculative. The engineer suggests simpler positioning systems could offer sufficient accuracy for landing safety.
