In Pittsburgh, a quiet but consequential threshold was crossed when Astrobotic fired its Chakram engine — a rotating detonation rocket engine — for a sustained 300 seconds, producing over 4,000 pounds of thrust per engine. Where conventional propulsion relies on steady combustion, this technology harnesses a continuous ring of detonation, a physics-defying loop that has long promised greater efficiency but resisted practical realization. This test does not yet put the Chakram in space, but it places it, for the first time, within reach of the real — a reminder that the distance between theory
