The Interplanetary Expansion Treaty is the first binding multilateral framework for the peaceful, permanent, civilian-led colonisation of the Moon, Mars, and Venus. We are calling on governments to sign it — now, before the window closes.
– signatories from – countries
China has a permanent orbital station and a declared lunar base programme. Russia retains deep-space propulsion expertise and treaty leverage. The Artemis Accords are a US-led framework — neither universal nor binding. The Moon is ungoverned. Mars is ungoverned. Venus is ungoverned.
The nation — or coalition — that defines the rules of the solar system now will shape the next five centuries of human civilisation. That window is open today. We are calling on the governments of the world to act.
