text: re-usable spacecraft for t~e study of the Earth's environment from space. The programme and conditions of co-operation in the areas· referred to in the Protocol will be defined by individual protocols or by specific agreements between the parties. There has been bilateral Soviet-United States co-operation in the exploration and use of outer space for peaceful purposes since 1958. Initially it took the form of contacts and exchanges between individual scientists and specialists and then it came to be based on agreements between the USSR Academy of Sciences and NASA. Two intergovernmental agreements concerning co-operation in space were concluded in 1972 and 1977. A third Agreement between the USSR and the United States of America concerning co-operation in the exploration and use of outer space for peaceful purposes was signed in April 1987. It defines specific areas of~ and projects for co-operation; the list of these may be expanded by mutual agreement. The Soviet Union attaches great importance to the expansion of co-operation in the peaceful use of outer space with developing countries. Space co-operation with India takes various forms and has a long and successful history. The Agreement on the further development of economic and trade co-operation between the USSR and India concluded in 1973 contained a general undertaking by the parties to develop and strengthen scientific and technological co-operation, including in the field of space research. Between 1972 and 1979, three agreements of an interdepartmental nature were signed between the USSR Academy of Sciences and the Indian. Space Research Organization (ISRO). In 1977, a Soviet-Indian -station for the observation of artificial Earth satellites was set up on Indian territory. The scientific equipment for this station was provided by the USSR and the countries members of INTERCOSMOS. The joint flight by Indian and Soviet astronauts on a Soviet spacecraft 
analysis: The text discusses international cooperation in the peaceful use of outer space, mentioning agreements and projects between the Soviet Union and the United States, as well as between the Soviet Union and India. The focus is on scientific research and technological cooperation, with a specific emphasis on the study of the Earth's environment from space. This suggests that the category should be related to scientific research and technology.
