Science and technology are shaping both the future and the legacy of major infrastructure today. American Airlines says it will bring SpaceX’s Starlink internet to more than 500 aircraft from 2027, underscoring how satellite connectivity has become a new battleground in commercial aviation. But Starlink’s rapid rise is also exposing tensions on the defense side, with the Pentagon reportedly disputing what SpaceX wants to charge for military use during the Iran conflict. Elsewhere, the energy transition was made vividly physical in Australia, where the towering chimneys of the retired Liddell coal station were felled in a controlled demolition, marking the end of a half-century industrial landmark. And in Canada, Infini Resources is narrowing uranium targets at Portland Creek ahead of new drilling, a reminder that as old energy assets come down, the search for materials tied to the next phase of power production is only intensifying.
