ISAM

In-Space Servicing, Assembly, and Manufacturing TECH

On-orbit operations that refuel, upgrade, repair, assemble, or build spacecraft — extending lifetimes and enabling larger structures than any rocket fairing.

DEFINITION

In-Space Servicing, Assembly, and Manufacturing (ISAM) covers any operation performed in orbit on a satellite or structure after launch: refueling, life extension, repair, augmentation, on-orbit assembly of larger structures, and additive manufacturing.

WHY IT MATTERS

ISAM is the architecture layer that lets you stop treating spacecraft as disposable. Refueling alone breaks the propellant-budget tyranny that drives most spacecraft mass. Northrop Grumman MEV, Orbit Fab, Astroscale, and a wave of well-funded entrants are turning ISAM from demo to commercial service.

WHERE YOU'LL SEE IT
  • Life-extension docking for GEO comsats
  • Refueling depots for high-cadence missions
  • On-orbit assembly of large structures (telescopes, antennas, habitats)
