Thanks for the thorough comment—yes, the heat pipes etc haven’t been accounted for. Might be a future addition but the idea was to look at some key large parts and see where that takes us in terms of launch. The pipes would definitely skew the business case further. Similarly, the analysis is missing trusses.

Don’t even get me started on the costs of maintenance. I am sweating bricks just thinking of the mission architecture for assembly and how the robotic system might actually look. Unless there’s a single 4 km long deployable array (of what width?), which would be ridiculous to imagine.
