THE LUNAR LEDGER:

A GLOBAL LUNAR DATABASE OF OBJECTS AND ACTIVITIES

Powered by the Open Lunar Foundation, a Permanent UN COPUOS Observer

The Lunar Ledger Project, launched in 2022, aims to establish a centralized and reliable system for tracking lunar exploration activities. It brings together information from all stakeholders and public sources to create a comprehensive record of missions and operations.

By providing a transparent, shared baseline of lunar activity, the Ledger supports coordination, reduces risk, and is fundamental to the safe and sustainable development of the Moon.

value for every stakeholder

  • Commercial lunar actors

    Reduce risk, improve planning, and increase operational efficiency with centralized, neutral, and verified mission data.

  • Government and state actors

    Upholding privacy, transparency, and global alignment through collaborative governance and strong regulatory partnerships.

  • MIT - AstroAnt

    academics and Researchers

    Leverage mission intelligence to identify cost-sharing and payload opportunities, accelerating shared deployments.

A Lunar Ledger enables responsible, cooperative development.

Shared commitment is central to sustainable, safe, and coordinated lunar activity.

Humanity is returning to the Moon, with governments, scientific organizations, and commercial ventures preparing for new opportunities. Over 100 missions are planned by 2030, supported by significant investment and increasing momentum towards a sustained lunar presence.

However, current progress highlights a need for greater transparency and coordination. Clear, reliable information is essential to support safety, effective planning, and responsible growth.

The Lunar Ledger is a collaborative initiative developed to address this need. By providing centralized, verified mission data globally, it enables stakeholders across sectors to reduce risk, improve coordination, and contribute to a sustainable lunar environment.

Participate in the Lunar Ledger to support informed decision-making and shared success on the Moon.

"A Lunar Registry could work as an essential tool for coveted locations where we will see increased activities, such as the Peak of Eternal Light or the Lunar South Pole."
