The Space Investigations Documentation System (SIDS) Report DECEMBER 1974 NATIONAL SPACE SCIENCE DATA CENTER NATIONAL AERONAUTICS AND SPACE ADMINISTRATION * GODDARD SPACE FLIGHT CENTER, GREENBELT, MD. NSSDC 74-16 The Space Investigations Documentation System (SIDS) Report December 1974 FOREWORD The Space Investigations Documentation System (SIDS) report is prepared by the National Space Science Data Center (NSSDC) at Goddard Space Flight Center for the Office of Space Science (OSS) at NASA Headquarters. The report will serve as a users guide for OSS manage- ment. In addition it is intended to provide the professional community with information about OSS current and planned investigative activity in a broad range of scientific disciplines. The report provides brief descriptions for these investigations, as well as the approximate time periods when each investigation operates and collects data. The SIDS report replaces the Space Science and Applications Program document (NHB 8030.2) from April 1960 to August 1968. Information on the supporting research and technology (SRT) and sounding rocket (SR) programs contained in that predecessor report has been deleted from SIDS, but it is available from the Office' of the Associate Administrator for Space Science. The SIDS report differs from the Report on Active and Planned Spacecraft and Experiments, edited by Julius Brecht and published by NSSDC in January 1974, in that it includes experiments and spacecraft of direct concern to OSS. At the spacecraft level, the report includes names of the program scientist and program manager. At the experiment level, the report shows whether an experiment was approved or approved conditionally, specifies the responsible OSS Division, and lists the SIDS investigation discipline codes. I would like, to acknowledge the cooperation of Battelle Memorial Institute, NASA Headquarters, and the National Space Science Data Center for assisting in the development of the report, obtaining informa- tion, and offering suggestions for the preparation of this report. NSSDC plans to publish a supplement to this report within 6 months and a cumulative edition annually. Henry J.

INTRODUCTION The Office of Space Science (OSS) and the professional community have a. continuing need for information relating to and describing the scientific experiments conducted on OSS space flight missions. The Space Investigations Documentation System (SIDS) report includes all active and planned experiments approved by the Associate Administrator for Space Science, plus a few other missions of direct interest to OSS. The SIDS report is arranged to provide information in a number of forms, i.e., geographic, institutional, principal investigators or team leaders, etc. SIDS is a formalized information system to meet these goals. The SIDS report and subsequent editions will provide details on current and planned experiments. The objective of SIDS is to establish, maintain, and operate a Space Science Steering Committee flight experiments project information system providing the capability to respond to report requirements and also internal and external queries on flight experiments. It has been designed to provide, as a single source, summaries of all approved space flight investigations and experimental and theoretical supporting research. The SIDS report will provide the professional community with information on current as well as planned spacecraft activity in a broad range of scientific disciplines for OSS. By providing brief descriptions of the spacecraft and experiments, as well as the approxi- mate time periods when data are being accumulated, it is hoped that this report will be useful to many people interested in the scientific, applied, and operational uses of such data. The contents and format of individual sections are described at the beginning of each section. 1.1 AVAILABILITY OF THIS REPORT The Space Science Steering Committee Secretariat will provide copies of the SIDS report and future supplements to an individual or organiza- tion who can establish a need, in writing or by telephone, for this infor- mation. The official address for requests is: NASA Headquarters Office of Space Science Space Science Steering Committee Secretariat Code: SS Washington, D.C. 20546 Phone: 202 755-8393 1.2 REQUESTS FOR ADDITIONS/CORRECTIONS All additions/corrections to the SIDS report should be sent directly to the Secretariat of the Space Science Steering Committee. To be included in the June 1975 supplement, these must reach the Secretariat by April 14, 1975. 2. DESCRIPTIONS OF SPACECRAFT AND EXPERIMENTS This section contains descriptions of spacecraft and experiments. They are sorted fir-s»1-gl3^ spacecraft common .name.- Within each spacecraft listing, experiments are ordered by the principal investigator's or team leader's last name. If the spacecraft common name is not known, the spacecraft can be found by referring to an alternate name found in the Index of Spacecraft and Experiments, section 3.1. Each spacecraft entry heading consists of the spacecraft common name, alternate names, NSSDC ID code, last reported state of the space- craft, launch date or planned launch date, weight, launch site, launch vehicle, sponsoring country and agency, orbit parameters if appropriate, and personnel. For unlaunched satellites, a set of planned orbit parameters is given. For launched orbiting spacecraft, two sets of orbit parameters are given; i.e., initial orbit parameters calculated shortly after launch and recent orbit parameters. No orbit parameters are given for lander or fly-by missions. The spacecraft brief description follows immediately below each heading. Each experiment entry heading consists of experiment name, NSSDC ID code, last reported state of the experiment, the OSS division, the relevant SIDS disciplines, and the experiment personnel. The experiment brief description follows immediately below each heading.
