    • Umbilicals are connected to the Launch Umbilical Tower (LUT) (JPG: wikipedia.org)

    • From bottom to top, the umbilicals are:

      • Aft Umbilical Carrier #1 - various pneumatic couplings, 8 electrical connectors and a 6" LOX connector

      • Aft Umbilical Carrier #2 - various pneumatic couplings, 8 electrical connectors and a 6" RP-1 connector

      • Aft Umbilical Carrier #3 - various pneumatic couplings, two 4" air conditioning couplings

      • S-IC Inter / "Aft" - LOX fill and drain, and GHe for POGO suppression

      • S-IC Fwd - GN2 air conditioning

      • S-II Aft  - Human access

      • S-II Inter - LH2, LOX, vent line, pneumatic/electrical, air conditioning, and instrument cooling

      • S-II Fwd - GH2 vent, electrical/pneumatic interfaces

      • S-IV B Aft - LH2, LOX, electrical/pneumatic, and air conditioning

      • S-IV B Fwd - Split umbilical, serving S-IVB forward section (GH2, electrical and pneumatic) and IU section (air conditioning, GH2, electrical and pneumatic)

      • Service Module - Air Conditioning, vent line, coolant, and electrical/pneumatic interfaces

      • Command Module Access Arm - crew access

      • Bonus: a 360 degree, 25 ton crane (reddit.com/r/space)
