Launch Ingot May 2026

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.

This is the ingot’s moment of sacrifice. The upper stage performs a “ballast jettison” burn. Explosive bolts fire. Pneumatic pushers shove the ingot away from the stack at 1.5 meters per second. launch ingot

He taps the metal. “This thing will outlast every satellite on this manifest. Long after the last telemetry packet dies, the ingot will still be up there. Circling. Waiting.” Is the launch ingot a necessary evil or a reckless source of debris? For decades, lead bricks and concrete rings sufficed

This is the . And without it, the satellite industry would grind to a halt. The Ballast Problem To understand the ingot, you first have to understand physics. A rocket is a column of fire seeking balance. To fly straight, its center of gravity must sit perfectly above its center of thrust. But the primary payload—say, a massive GEO communications satellite—rarely fits that equation on its own. The upper stage performs a “ballast jettison” burn
