INTERNATIONAL

ASTRONAUTICAL

CONGRESS

Munich, FRG, 16-23 September 1979 Space Developments for the Future of Mankind The theme “Space Developments for the Future of Mankind” has a broad scope that will be reflected throughout the programme of the 30th Congress of the International Astronautical Federation. It will provide the background for the 19th IAF Invited Lecture, to be followed by a Forum session on “Mission Models and Space Planning” with a panel of leading international space specialists and audience participation. The Congress programme will feature a symposium on “Space Transportation Systems”, another one on “Manned Operations in Space” and a third on “Application Satellites”, in addition to sessions on various specialized subjects, as well as symposia of the International Academy of Astronautics, the annual Colloquium of the International Institute of Space Law, and the 9th IAF International Student Conference. The Congress will be held in Munich, Federal Republic of Germany, from 16 to 23 September 1979, upon the invitation of the Deutsche Gesellschaft fur Luft- und Raumfahrt and co-sponsored by the Hermann-Oberth-Gesellschaft. The Congress is open to participants from all nations. Individuals who wish to present a paper do not have to be affiliated with or sponsored by a Member Society of the Federation, of which there are now 58 in 36 countries. The deadline for abstracts was 15 March 1979. Acceptance of papers for presentation at the Congress does not imply acceptance for publication. Proceedings will appear in a volume of selected general-interest and survey papers. Additional technical papers will be selected for publication in the journal, Acta A’stronauficu.

1.7. XVII GENERAL ASSEMBLY OF IUGG

Information of tbe XW General Assembly of IUGG and Associated IAGA Activities including IMS Symposium in 1979 in Australia (7) Canberra, 2-l 5 December 1979 The XVII General Assembly of IUGG will be held in Canberra, Australia, from 2 to 15 December 1979, in response to the invitation from the Australian Academy of Science. The First Circular was issued in March 1978 by the Local Organizing Committee in Australia. This outlines assembly programmes, scientific excursions, and arrangements for the assembly (including the information on lodging, registration fees etc.). The Second Circular will appear in December 1978, and this will include more detailed information on the scientific symposia, registration forms, paper submission, and remarks for the participants. The IUGG circulars are available from Dr. B. P. Lambert, Executive Director, Organizing Committee for XVII IUGG General Assembly, Australian Academy of Sciences, P.O. Box 783, Canberra, A.C.T. 2601, Australia. In connection with the IUGG General Assembly, all the International Associations under IUGG will have their own scientific sessions. Although the outlines of these Association activities are listed in the IUGG Second Circular, the detailed information is available on request from the Secretaries General of the participating Associations. During the XVII IUGG General Assembly of IUGG, IAGA will hold IAGA sessions in both weeks. Another important activity of IAGA in Australia in connection with the IUGG General Assembly will be the First Major Symposium on International Magnetospheric Study of SCOSTEP and IAGA, to be held during 27 November-l December 1979 at La Trobe University in Melbourne. The following pages describe the general schedule for the IUGG/IAGA Assembly, explanations on the IMS Symposium and those of the IUGG Symposia under IAGA leadership and those IAGA sessions which are of direct (3From IAGA News No. 17, November
