Depuis le 21 Juillet 1969 une ere nouvelle s'est ouverte dans 3 notre connaissance du systeme TerreLune avec l'accu. mulation de mesures 3 de distances ultraprecises aux reflecteurs laser deposes sur la surface lunaire. Au cours des recherches effectuees a partir de cette nouvelle technique il s'est tres vite avere que le champ d'applications etait 3 considerable et qu'il fallait completement reviser certaines theories anterieures. Avec des observations au niveau de quelques centimetres 3 il n'est plus possible d'etudier des phenomenes isolement et3 quel que soit le pole d'interet fixe il est necessaire aussi d'etudier 3 conjointement les autres aspects du systeme. Tres vite3 il est alors apparu que les recherches potentielles relatives a ce type d'observa tions ne se bornaient pas seulement aux applications lunaires mais pouvaient recouvrir un domaine plus vaste en Astronomie Geodesie 3 3 Geophysique Cosmologie etc . . . C'est ainsi qu'est ne le programme 3 3 international EROLD avec comme but plus specifique l'etude de la 3 rotation terrestre mais avec des aspects connexes lies en particulier 3 a la dynamique du systeme TerreLune dans son ensemble. Il etait alors naturel de faire le bilan a un niveau eleve de ces annees de recher 3 3 ches dans cette nouvelle phase de la connaissance. Par ailleurs d)autres types de techniques modernes ont egale 3 ment vu le jour durant cette derniere decennie avec entre autres 3 applications la determination de la rotation de la Terre.
