During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade. -

Alexander, Editor Marshall Space Flight Center • MSFC, Alabama National Aeronautics and Space Administration Marshall Space Flight Center ° MSFC, Alabama 35812 August 1996 PREFACE The effects of the natural space environment on spacecraft design, development, and operation are the topic of a series of NASA Reference Publications currently being developed by the Electromagnetics and Aerospace Environments Branch, Systems Analysis and Integration Laboratory, Marshall Space Flight Center. This primer provides an overview of seven major areas of the natural space environment including brief definitions, related programmatic issues, and effects on various spacecraft subsystems. The primary focus is to present more than 100 case histories of spacecraft failures and anomalies documented from 1974 through 1994 attributed to the natural space environment. A better understanding of the natural space environment and its effects will enable spacecraft designers and managers to more effectively minimize program risks and costs, optimize design quality, and achieve mission objectives. .o° 111 TABLE OF CONTENTS -
Clarification on the MDES's Demand Regarding Thaicom 5
- Translation – TC-CP 020/2020 12 November 2020 Subject: Clarification on the Ministry of Digital Economy and Society’s demand regarding Thaicom 5 To: The President The Stock Exchange of Thailand Reference is made to the Ministry of Digital Economy and Society (MDES)’s demand that the Company build and transfer the ownership of a new satellite to replace Thaicom 5 or otherwise pay MDES compensation in an amount equal to the price of a new satellite, which has resulted in a dispute to be resolved by arbitration. Thaicom Public Company Limited (the “Company”) would like to clarify that the Company has already fulfilled its obligation to launch satellites as required by the terms of the Concession. Therefore, the Company has no obligation to build a new satellite to replace Thaicom 5 as demanded by MDES. In addition, currently there are still two other satellites, i.e. Thaicom 4 and Thaicom 6, in operation, the ownership of which the Company has transferred to MDES. The operational life of the two satellites is also beyond the term of the Concession, and MDES has the right to manage the two satellites thereafter. The Concession was entered into nearly 30 years ago, with the parties agreeing to the terms regarding the work plan and principles for contract implementation which reflected the plan which had been proposed by the Company and approved by MDES. The focus was on the continuity of satellite service throughout the term of the Concession. The work plan, which forms part of the Concession, states that the Company will build 2 generations of satellites, with a total of 4 satellites. -

Classification of Geosynchronous Objects
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.

Ariane 5 Lifts Record Payload Into Space 11 August 2005
Ariane 5 lifts record payload into space 11 August 2005 This morning (Aug.11) an Ariane 5G launcher lifted off from Europe’s Spaceport in French Guiana. On board was the largest telecommunications satellite ever to be placed into geostationary transfer orbit. The mission was initially delayed during the two- hour-long launch window to verify telemetry readings from Ariane 5's mobile launch table, and the countdown subsequently resumed for an early morning takeoff from the ELA-3 launch zone. The heavyweight THAICOM 4 (IPSTAR) satellite had a lift-off mass of almost 6500 kg. Before this morning’s launch, the record for the heaviest telecommunications satellite to be placed into orbit belonged to the Anik F2 satellite, launched by an Ariane 5 launcher in July 2004. THAICOM 4, built for Shin Satellite Plc of Thailand, will provide businesses and consumers throughout Asia, Australia and New Zealand with various levels of Internet access services. The satellite has a total data throughput capacity of over 45 Gbps. This is the fourth Shin Satellite to be launched by an Ariane vehicle. An Ariane 4 vehicle launched the first satellite in 1993. The next launch to take place from Europe’s Spaceport will be Flight 168, an Ariane 5G dual launch mission scheduled for 29 September.
