The article "Interuniversal Spaceport: Architecture, Placement, Safety" examines three options for locating a facility for launching and receiving interuniversal expeditions: on Earth, on the far side of the Moon, and in space (Lagrange points L4/L5 or heliocentric orbit). For each option, estimates are provided for construction costs, labor requirements, transportation expenses, and operational costs, including transport hubs (airfield, cosmodrome, docking port) and evacuation means (ground transport, arriving ships, emergency shuttle). The Earth-based option is the cheapest (~$17 billion) and most accessible, but risky due to proximity to populated areas. It is recommended only for 1st generation probes with an instant destruction system. The lunar option (~$130 billion) is optimal for manned missions but requires a critical note: the Moon cannot be lost even in an emergency, as it affects Earth's stability. The space option at L4/L5 (~$255 billion) is suitable for medium-risk missions, while the heliocentric orbit (>10 million km, ~$508 billion) is intended for high-risk missions (pre-atomic universes, contact, reverse infiltration). The main conclusion: the higher the mission risk, the farther from Earth the interuniversal spaceport should be located, but each step into space increases the cost and complexity of the project by orders of magnitude. The article contains numerical engineering estimates and accounts for reverse infiltration risks, distinguishing it from existing conceptual works.
