    esoc European Space Operations Centre Robert-Bosch-Strasse 5 D-64293 Darmstadt Germany T +49 (0)6151 900 www.esa.int CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS Produced with the DISCOS Database Prepared by ESA’s Space Debris Office Reference GEN-DB-LOG-00211-OPS-GR Issue 20 Revision 0 Date of Issue 28 May 2018 Status Issued Document Type Technical Note Distribution ESA UNCLASSIFIED - Limited Distribution European Space Agency Agence spatiale europeenne´ Abstract This is a status report on geosynchronous objects as of 1 January 2018. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1523 objects for which orbital data are available (of which 0 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 519 are actively controlled, 795 are drifting above, below or through GEO, 189 are in a libration orbit and 19 are in a highly inclined orbit. For 1 object the status could not be determined. Furthermore, there are 59 uncontrolled objects without orbital data (of which 54 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1582.

  • System Analysis and Design of the Geostationary Earth Orbit All-Electric Communication Satellites
    https://doi.org/10.1590/jatm.v13.1205 REVIEW ARTICLE System Analysis and Design of the Geostationary Earth Orbit All-Electric Communication Satellites Parsa Abbasrezaee1,* , Ali Saraaeb2 1.Sapienza University of Rome – Aerospace Engineering School – Rome – Italy. 2.Khaje Nasir Toosi University of Technology – Aerospace department – Tehran – Iran. *Corresponding author: [email protected] ABSTRACT With the help of gathered data and formulas extracted from a previous conference paper, the all-electric geostationary Earth orbit (GEO) communication satellite statistical design was conducted and further studied with analytic hierarchy process (AHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods. Moreover, with the help of previously determined system parameters, the orbital ascension, orbital maintenance and deorbiting specifications, calculations and simulations were persuaded. Furthermore, a parametric subsystem design was conducted to test the methods reliability and prove the feasibility of such approach. The parametric subsystem design was used for electrical power subsystem (EPS), attitude determination and control system (ADCS), electric propulsion, telemetry, tracking and control (TT&C) in conceptual subsystem design level, which highly relies on the satellite type and other specifications, were concluded in this paper; other subsystem designs were not of a significant difference to hybrid and chemical satellites. Eventually, the verification of the mentioned subsystems has been evaluated by contrasting the results with the Space mission engineering: the new SMAD, and subsystem design book reference. Keywords: All-electric; GEO; AHP and TOPSIS Method; Maintenance; Deorbiting; Parametric. INTRODUCTION From the previous conference paper, the contrast between all-electric geostationary Earth orbit (GEO) communication and other hybrid and chemical satellite design has shown that using all-electric satellite design has many advantages.

Beginning in 1993, the international community came together to develop the medical systems for an international space station. Initially, this collaboration was bilateral in support of the Shuttle / Mir Space Station (Phase 1). However, the framework that was established to serve as the medical authority structure provided a foundation for the multilateral boards and panel, which were codified in the memoranda of understanding. The Multilateral Medical Policy Board, the Multilateral Space Medicine Board and the Multilateral Medical Operations Panel were developed in a collegial and mutually- beneficial environment by the men and women of the space agenicies of Canada, Europe, Japan, Russia, and the United States.

    NEWMARKET U3A: WINGS, WHEELS & WATER GROUP April 2020 Due to the Coronavirus pandemic restrictions this is a brief, light, but hopefully enlightening presentation for home study Space and Lunar Surface Travel: From thoughts in 1969 to the Lunar Rover and Beyond Photo taken at the Moon exhibition, National Maritime Museum, London December 2019 1 Space and Lunar Surface Travel: From Thoughts in 1969 to the Lunar Rover and Beyond As always, Tim’s April presentation for the WWW Group, about Apollo 13, The Apollo 9 Lunar Module bought back memories and set me thinking. In 1969 I was a 12-year-old boy, clearly excited by the Apollo Moon landing and wanting to collect anything and everything. My store of newspaper cuttings and magazines has survived. Last year, on the 50th anniversary of the event I re-read all these documents, and particularly enjoyed a magazine called “Moonslaught, the full story of man’s race to the moon”. It was a Purnell History of the 20th Century magazine, carrying an image of the Apollo 9 Lunar Module (”spider”) in a lunar landing conformation, and cost 4/-. The author was Reginal Turnill. (A copy of the magazine is held in the National Space Centre, in Leicester) An obvious connection of this magazine with Tim’s talk is the Apollo missions, but less obvious is that Reginald Turnill was also the journalist to first report on the Apollo 13 disaster, via the BBC World Service.
