Space Logistics Definitions

The current definition of Space Logistics as approved by the SLTC is:

The theory and practice of driving space system design for operability and managing the flow of materiel, services, and information needed throughout the system lifecycle.


  • EEO: Earth Equatorial Orbit
  • EML1: Earth-Moon Lagrange point 1
  • EPO: Earth Polar Orbit
  • ESL2: Earth-Sun Lagrange point 2
  • ISS: International Space Station
  • LEO: Lunar Equatorial Orbit
  • LPO: Lunar Polar Orbit
  • MEO: Mars Equatorial Orbit
  • MPO: Mars Polar Orbit


  • Space logistics: The art and science of managing the flow of materiel needed to support space operations.
  • Fuel depot: An in-space or surface space logistics node dedicated to propellant storage.
  • Logistics vehicle: A vehicle dedicated primarily to the movement of materiel between logistics nodes, such as the Space Shuttle, Progress, or ESA ATV.
  • Maintenance: Scheduled removal, rurbishment, replacement and upgrades.
  • Repair: Unscheduled remediation of equipment failures.
  • Space infrastructure: A network of surface and in-space nodes and arcs populated by space stations, surface bases and fuel depots, and the transportation systems that connect them.
  • Space station: An in-space node of a space logistics network.
  • Supply chain management: Distribution and inventory control of consumables, construction supplies and spares.
  • Surface base: A space logistics network node located on a planet, moon or asteroid.
