Looked around for comparison pictures, but can't find anyone (yet), probably because lunar gateway design is not yet stable. Or is it? I found several different designs.

Do they exist "blueprint" of LG, ISS, and possibly also MIR, to make a comparison?

--- edit ---

Orbital velocity provides a 3d paper model of a "minimal version" of Lunar Gateway, maybe usable to do some measurements:

Orbital Velocity Lunar Gateway 3d paper model


There are only Power Module (PPE), HALO module and Orion capsule.

I did some measurements:

  • PPE: 25x25x31 mm ; panels: 58x197 mm
  • HALO: 33 mm diameter, 16.5mm radius by 60mm length (plus a part around 10mm - protruding from an edge)

Scale is 1:100, hence:

  • PPE: 2.5x2.5x3.1 m; panels = 5.8 x 19.7 m
  • HALO: 3.3m diameter by 7 meters length

The design of the Gateway is still in flux, but here's an illustration from a couple of years ago showing it next to the ISS (lower right corner).
