The ingot does not deploy. It does not phone home. It becomes debris—a silent, 500-kilo brick now in a slightly lower parking orbit than the satellites it just supported. This is where the story gets controversial.
But as on-orbit manufacturing and refueling become real, the ingot’s days are numbered. Future rockets will likely use or active mass shifters to balance the stack, turning the ballast into usable fuel. launch ingot
For decades, lead bricks and concrete rings sufficed for test flights. But as the industry pivoted to (think SpaceX’s Transporter missions or Rocket Lab’s dedicated smallsat flights), a new problem emerged: variable mass. The ingot does not deploy
