Surely the only thing I can blog about today is this absolutely incredible news that NASA has successfully flown a helicopter on mars. “The drone, called Ingenuity, was airborne for less than a minute, but Nasa is celebrating what represents the first powered, controlled flight by an aircraft on another world.” Of course, there’s not much I can say about it, other than how awesome I find it. As a guy who has trouble controlling his powerchair sometimes, I can’t even begin to imagine the technical ingenuity which must have gone into this feat. In terms of human achievement, surely this is another huge milestone.
