AbstractPlanetary protection is a very wide subject because of the variety of physical conditions on individual planets and their moons. At present, we have good photographs or imagery, as well as other evidence, from most planets and from a selection of their moons. The most important factor is the presence or absence of any form of life. Material samples are available from the Moon and possibly, in the form of a few meteorites, from Mars. The danger of contamination has been recognized in the past and it became clear that some measures would have to be taken. The adoption of measures will have to be universal in missions to planets and their moons because for an undesirable contamination to occur, one failed measure of protection may be enough. The question is, if we can learn from experience gained in the last forty years in adopting laws, rules or unbinding recommendations for space activities. Several examples will be discussed, such as the amount of knowledge at a time when international treaties on space law were adopted, the consequences of the failed discussion at the United Nations on the definition of outer space, or of the break-up of Cosmos 954. Special attention will be devoted to the ongoing discussion of space debris in the UN Committee on the Peaceful Uses of Outer Space and its relevance for planetary protection, to the general compliance with the Registration Convention and to the experience gained with the recommendation to re-orbit geostationary satellites.
