Nasa space treaty to allow establishment of lunar 'safety zones'

US accused by Russia of trying to circumvent 1967 treaty banning ownership of areas of the moon

Countries joining Nasa's exploration of the moon will be asked to sign up to a series of guiding principles known as the Artemis accords. Announced on 15 May, the accords are a set of broad themes that the agency hopes will form the basis of agreements to be negotiated with each country involved in the effort to land the next humans on the moon by 2024.

Based in part on the UN's outer space treaty of 1967, the Artemis accords reassert that all activities should be undertaken only for peaceful purposes, and add that all plans should be communicated transparently with no secrecy. They commit the partners to using open international standards to allow machinery and equipment to function easily together, to provide emergency assistance to other astronauts and to mitigate the creation of space debris.
