3Modules

  • COL - ESA Module ("Columbus")
  • JPM - Japanese Pressurized Module (part of "Kibo")
  • LAB - US Lab ("Destiny")
  • NOD1, NOD2, NOD3 = Nodes, which connect the elements of the ISS.
    • Node 1 ("Unity") connects the U.S. and Russian segments.
    • Node 2 ("Harmony") connects the U.S., European, and Japanese laboratories, as well as PMA-2.
    • Node 3 ("Tranquility") is attached to the port side of Node 1 and provides accommodation for life-support equipment.
  • SMP = Russian Service Module ("Zvezda")

4Absorbed dose is broken out into SAA and GCR contributions, estimated based on the ISS trajectory and a geomagnetic field model
