solar-terrestrial physics; space astronomy and astrophysics; the study of the solar system, planets and comets; investigation of the atmosphere and the study of the Earth from space; fundamental research concerning microgravitation; space biology and medicine, etc. The Agreement confirms an understanding in principle that an astronaut from the Federal Republic of Germany will participate in a space flight on a Soviet space vehicle and the Mir orbital station. The conditions for this flight are to be agreed between the competent organizations in the USSR and the Federal Republic of Germany on the basis of a separate understanding. v. Co-operation in various aspects of the practical application of space technology 1. In 1978, a Convention on the transmission and use of data from remote sensing of the Earth from space was signed in Moscow. The parties to this Convention are the USSR, Bulgaria, Cuba, Czechos_lovakia, the Democratic People's Republic of Korea, the German Democratic Republic, Hungary, Mongolia, Poland, Romania and Viet Nam. The Convention is a major legal instrument which aims at regulating the parties' activities regarding remote sensing with the help of space vehicles and the development of bilateral or multilateral co-operation in the design a.nd development of the requisite remote-sensing hardware and methods. It played a positive role at the time of the establishment of the international legal regime for.the handling of remote-sensing data and of the information derived from it. The USSR State Committee on Science and Technology has concluded agreements on co-operation in remote sensing with the: Czechoslovak Federal Ministry for the Development of Technol,ogy and Capital Construction (1978); A/Ac.ios/C.2/16/Add.5 page 9 Polish Chief Directorate for Geodesy and .cartography (1978); Romanian National Council for Science and Technology (1979); Hungarian State Committee for Technological Development (1979); Vietnamese State Committee for Science and Technology (1979); 
**Analysis**
