Miscellaneous Items. (This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.) GRO (1991-027B) was maneuvered in October 1993 to move to a higher apogee at 450 km; a similar maneuver in late November will move the perigee to 450 km. These maneuvers enable extension of the life span of the spacecraft. ESA BULLETIN, August 1993, pages 91-94 A DESCRIPTION OF MIR STATION The MIR space station circles the Earth at an altitude of between 350 and 400 km in an orbit with an inclination of 51.6 degrees. In its present configuration, MIR consists of four main modules: the MIR core module and the scientific modules known as KVANT, KVANT-2,Ó and KRISTALL. The MIR core module, which was launched in February 1986, has a mass of approximately 21 tons, a length of about 13.1 m, and a maximum diameter of 4.2 m. It consists primarily of a passage area with five docking ports, a working area housing the command station, living/eating and hygiene facilities, and a propulsion section through which a tunnel allows access to the KVANT module. KVANT, an astrophysics module that accommodates instruments from several countries, was docked to the MIR core module in April 1987. It is about 5.8 m long, has a maximum diameter of 4.15 m, and a mass of about 11 tons. KVANT-2, a module housing scientific and technological experiment equipment, a shower facility, and an airlock supporting extravehicular activities (EVA) by the crew, was docked to the station in December 1989. It has a mass of 19.5 tons, a length of 11.9 m, and a maximum diameter of 4.35 m. The KRISTALL module joined the station in June 1990. It is mainly dedicated to technological research, such as semiconductor and biological experiments. It also houses Earth-observation instruments. The mass and dimensions of KRISTALL are similar to those of KVANT-2. In August 1992, a thruster package, known as SOFORA, was installed on a 14-m mast mounted on top of the KVANT module. These thrusters allow efficient and propellant-saving attitude control of the station. Two further modules are plannned to be added to MIR. The PRIRODA module, mainly dedicated to Earth- observation tasks such as ocean surface-temperature measurement and studies of ocean/atmosphere interactions, and the SPECTR module, supporting studies of the Earth's atmosphere. Logistical resupply of MIR is provided by the unmanned PROGRESS system, with a payload capacity in the order of 2.5 tons. The crew is transported to and from the station with the SOYUZ-TM vehicle, which can accommodate three astronauts/cosmonauts per trip. Both the SOYUZ-TM and PROGRESS are expendable systems and are launched by the SOYUZ launch vehicle. The results of the experiments, including samples, film, etc., are usually returned to Earth by the astronaut/cosmonaut on board the SOYUZ-TM capsule. A special unmanned re-entry capsule enhances these return capacities. ERRATUM In SPX-472 covering February 1993 launches, the correct launch date of OXP-1 (1993-009A) is 9 February 1993. SPACEWARN BULLETIN ------------------- This Bulletin is intended to serve as an international communication mechanism for the rapid distribution of information on satellites and space probes. The material it contains is based on guidelines in "COSPAR Guide to Rocket and Satellite Information and Data Exchange", COSPAR Transactions #8, December 1972, and various Committee on Space Research (COSPAR) resolutions. The SPACEWARN Bulletin is issued to COSPAR's national contacts for satellite information, Satellite Regional Warning Centers, and various leaders and participants in COSPAR activities. Recipients are requested to arrange for any further appropriate distribution of this bulletin to interested individuals and institutions in their regions or countries. All bulletins beginning with January 1991 (SPX-447) are now available on-line; the SPX number increases by one for each succeeding month (for example January 1993 bulletin is SPX-471).

CATEGORIES OF SPACECRAFT To improve the effectiveness of international distribution of satellite and space probe information via the SPACEWARN system, spacecraft are identified in categories according to the urgency and detail of information needed by the scientific community as: CATEGORY I: Spacecraft particularly suited for international participation, especially those for which prior arrangements have been circulated through COSPAR channels: essentially continuous satellite radio beacons usually on frequencies less than 150 MHz designed for cooperative ionospheric experiments; satellites with continuous telemetry of scientific experiments. Some of these may be balloon satellites, flashing satellites, or satellites in orbits of particular interest for which optical observations from the ground constitute a scientific experiment. CATEGORY II: Space experiments of unusual general scientific or popular interest: manned space flights or space probes if not for some reason included in Category I. CATEGORY III: All other space experiments: satellites with command telemetry only, test vehicles, etc., if not included in Category I or II. The SPACEWARN Bulletin contains the following information. Please note the accompanying explanations, where appropriate, as to coverage and sources of information since this is not repeated in the text. A. List of Recent International Designations. This list continues the tables given in previous bulletins.It also confirms the tentative designations assigned by the IUWDS World Warning Agency for Satellites acting on behalf of COSPAR via telegrams distributed over the SPACEWARN system. B. Texts of Launching Announcements. This section gives the texts of launching announcements of satellites and space probes received by the IUWDS World Warning Agency for Satellites at the NSSDC/WDC-A-R&S during the previous month. C. Spacecraft Particularly Suited for International Participation (Category I). These data are based on launching announcements or on information received from individuals, launching authorities, FBIS reports, and news magazines. Also included are decays of major objects, and miscellanous items.
