C()Uf?SE ON “MOTION OF THE ORBITING SPACE VEHICLE” Toulouse, France, 2-13 June 1980
Since 1965, the Centre National d’Etudes Spat&s (CNES) has organized every year a Course of Space Technology intended for French and foreign research workers, engineers and students. In 1980 the subject of the course will be: “Motion of the Orbiting Space Vehicle”. 15
The aim of this course, to be held from 2 to 13 June 1980 at the Toulouse Space Centre (France), is to give a basic tuition on the methods of attitude and orbit determination, interplanetary trajectories and atmospheric re-entry. Many examples taken from space systems which are now operational, such as Argos, Symphonie, Meteosat, or under study, like Venera, asteroids, SPOT, Telecom 1, will be provided to illustrate the lectures. This course, which is of the Master of Sciences level, is especially designed for: engineers who wish to get a better understanding of the problems related to the motions of the orbiting vehicle and the techniques used to control these motions; research workers who will have to propose space experiments and wish to deepen their knowledge on orbital and attitude constraints; students who wish to perfect their training. The following main topics will be covered: notes on mechanics; orbit determination; attitude determination; control of orbiting satellites - orbit insertion, station keeping. . . ; astronautics - planetary missions; atmospheric re-entry - guided or natural re-entry. The number of French and foreign participants is limited. Lectures will be given in French only and foreign applicants should have a good knowledge of the French language. No registration fee is requested. Registration forms were to be returned to the address indicated below before 1 March 1980. Late applications will be considered if places are still available.

1.10.SUMMER SCHOOL OF SPACE PHYSICS: FORMATION OF PLANE-TARYSYSTEMS
Grasse, France, l-28 August 1980 Since 1966, the Centre National d’Etudes Spatiales (French Space Agency) has organized a Summer School of Space Physics every two years to enable some 40 young French and foreign research workers with Master’s degree or equivalent to improve their knowledge on a theoretical subject of space physics. With the development of planetology, it seems quite opportune that the 1980 Summer School should deal with the origin of the solar system, and more particularly the 16
