NATIONAL COMMITTEE OF THE INTERNATIONAL SCIENTIFIC RADIO UNION Publication 1468 NATIONAL ACADEMY OF SCIENCES NATIONAL RESEARCH COUNCIL Washington, D.C. 1966 Library of Congress Catalog Card No. 55-31605 Available from Printing and Publishing Office National Academy of Sciences 2101 Constitution Avenue Washington, D.C. 20418 Price: $10.00 October28,1966 Dear Dr. Seitz: I ampleasedto transmitherewitha full report to the NationalAcademy of Sciences--NationalResearchCouncil,onthe 15thGeneralAssemblyof URSIwhichwasheldin Munich,September5-15, 1966. TheUnitedStatesNationalCommitteeof URSIhasparticipatedin the affairs of the Unionfor forty-five years. It hashadmuchinfluenceonthe Unionas,.for example,in therecent creationof a Commissiononthe Mag- netosphere.ThisnewCommission,whichis nowvery strong,demonstrates the ability of theUnion,oneof ICSU'sthree oldest,to respondto the changingneedsof its field. AlthoughtheUnitedStatessendsthelargest delegationsof anycountry to the GeneralAssembliesof URSI,theyare neverthelessrelatively small becauseof thestrict mannerin whichURSIcontrolsthe size of its Assem- blies. This is donein order to preventineffectivenessthroughuncontrolled participationbyvery largenumbersof delegates.Accordingly,our delega- tions are carefully selected,andcomprisepeoplequalifiedto prepareand presentour NationalReportto the Assembly.Thepre-Assemblyreport is a report of progressin radio sciencein the UnitedStatesduring the precedingthree years (notto be confusedwith thepost-Assemblyreport herewith). It will be publishedin thepresentinstancepartly in the November 1966issueandpartly in theDecember1966issueof "RadioScience,"a journal publishedby ESSAof the U.S.Departmentof Commercein coopera- tion with theUnitedStatesNationalCommitteeof URSI. Becauseparticipationatthe URSIAssembliesis sostrongly limited, our Committeefeels that it is incumbentuponit to publisha full report of the scientific andadministrativeproceedingsof eachAssemblyas soonas possibleafterwards. AlthoughURSIitself alsopublishescompletereports, theseare very expensiveandslowin appearing.Ourreport is notpolished followingan Assembly(heldin Decemberin Assemblyyears),andrelatively inexpensive.To accomplishthis requires diligent andprompt reportingby manymembersof the Delegation,muchcooperationandassistancefrom theAcademystaff, a subsidy,andaboveall, muchwork onthepart of our Vice-Chairmanonwhomtheresponsibilityfor editingandproducingthe report traditionally falls. In transmittingthepresentreport, therefore, I wantto expressthe gratitudeof the Committeeto all membersof its Dele- gationwhoservedas reporters; to our staff assistantMiss JoyeeHannaum whocompiledall thematerialin Munichandtypeda largepart of it in pre- liminary form; to NationalAeronauticsandSpaceAdministrationHead- quartersfor avery essentialsubsidy;andaboveall to our Vice-Chairman Professor E. C. Jordanof theUniversityof Illinois. TheCommitteealso acknowledgeswith muchgratitudethe supportof governmentagencies, particularly the NationalScienceFoundationandthe Officeof NavalResearch, in providingtravel fundsto a substantialnumberof personsfrom academic institutionsin theDelegation. Thegreatvalueof thesepost-Assemblyreports of the UnitedStates NationalCommitteehasbeenwidelyrecognizedoutsidethe UnitedStates andthis time theUnionitself is undertakingto report in a rapid andin- expensivemanner.If the Union'seffort is successful,this maybethe last time that theUnitedStatesCommitteeitself will mountsuchaneffort. Lastly, it is my pleasureto inform youthat Professor SamuelSilver of the Universityof CaliforniawaselectedPresidentof URSI;Professor William E. Gordonof RiceUniversity receivedthevan der Pol GoldMedal AwardandwaselectedVice-Chairmanof the Commissionon RadioPropa- gationin Non-IonizedMedia;Professor Colin O.Hinesof theUniversityof ChicagowaselectedChairmanof the Commissiononthe Ionosphere;Pro- fessor HenryG.Bookerof theUniversity of California at SanDiegowas re-elected Chairmanof theCommissionontheMagnetosphere;andProfes- sor Marvin Chodorowof StanfordUniversitywaselectedVice-Chairmanof the Commissionon RadioElectronics. Yoursvery truly, Millett G.Morgan,Chairman UnitedStatesNationalCommittee InternationalScientificRadioUnion NationalAcademyof Sciences--NationalResearchCouncil Dr. Frederick Seitz,President NationalAcademyof Sciences--NationalResearchCouncil 2101ConstitutionAvenue Washington,D.C. Preface Because of severe restrictions on the size of the delegation to a General Assemby, those appointed as delegates have an obligation to inform their colleagues as quickly as possible on the activities of the Assembly. For this reason the U.S. National Committee of URSI considers the prompt issuance of its report to be one of its major responsibilities to the scientific community. This report attempts to summarize the administrative actions as well as the scientific sessions of the General Assembly. The report itself represents the combined efforts of the entire United States delegation, for nearly every delegate was called upon to report at least one session. The major burden of the task fell to the U.S. Com- mission chairmen-designate, each of whom, as Chief Reporter for his Commission, was responsible for the reporting of its sessions. Partly because of the thoroughness of the re- porting, it has been necessary to condense many of the con- tributions to keep the over-all size of this report within reasonable bounds. The chief reporters were: Commission I Dr. Bruno Weinschel Commission II Mr. Arthur B. Crawford (for Dr. D. C. Hogg) Commission III Professor O. G. Villard Commission IV Professor K. L. Bowles Commission V Professor W. Erickson Commission VI Dr. R. C. Hansen Commission VII Professor H. Heffner It is a pleasure to acknowledge the unstinting cooperation of each of the chief reporters, and through them to thank all reporters. It would not have been possible to meet publication dead- lines without the generous aid of the National Academy of Sciences staff, and particularly the competent help of Miss Joyce Hannaum, Administrative Assistant, USNC-URSI. She deserves the thanks of the entire National Committee for invaluable assistance in the preparation of this report, both during and after the General Assembly. E. C.

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.
