6. the INTELSAT 17 Satellite
TWO COMMUNICATIONS SATELLITES READY FOR LAUNCH Arianespace will orbit two communications satellite on its fifth launch of the year: INTELSAT 17 for the international satellite operator Intelsat, and HYLAS 1 for the European operator Avanti Communications. The choice of Arianespace by leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Based on its proven reliability and availability, Arianespace continues to confirm its position as the world’s benchmark launch system. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads. Arianespace and Intelsat have built up a long-standing relationship based on mutual trust. Since 1983, Arianespace has launched 48 satellites for Intelsat. Positioned at 66 degrees East, INTELSAT 17 will deliver a wide range of communication services for Europe, the Middle East, Russia and Asia. Built by Space Systems/Loral of the United States, this powerful satellite will weigh 5,540 kg at launch. It will also enable Intelsat to expand its successful Asian video distrubution neighborhood. INTELSAT 17 will replace INTELSAT 702. HYLAS 1 is Avanti Communications’ first satellite. A new European satellite operator, Avanti Communications also chose Arianespace to orbit its HYLAS 2 satellite, scheduled for launch in the first half of 2012. HYLAS 1 was built by an industrial consortium formed by EADS Astrium and the Indian Space Research Organisation (ISRO), using a I-2K platform. Fitted with Ka-band and Ku-band transponders, the satellite will be positioned at 33.5 degrees West, and will be the first European satellite to offer high-speed broadband services across all of Europe. -
Atlas Launch System Mission Planner's Guide, Atlas V Addendum
ATLAS Atlas Launch System Mission Planner’s Guide, Atlas V Addendum FOREWORD This Atlas V Addendum supplements the current version of the Atlas Launch System Mission Plan- ner’s Guide (AMPG) and presents the initial vehicle capabilities for the newly available Atlas V launch system. Atlas V’s multiple vehicle configurations and performance levels can provide the optimum match for a range of customer requirements at the lowest cost. The performance data are presented in sufficient detail for preliminary assessment of the Atlas V vehicle family for your missions. This guide, in combination with the AMPG, includes essential technical and programmatic data for preliminary mission planning and spacecraft design. Interface data are in sufficient detail to assess a first-order compatibility. This guide contains current information on Lockheed Martin’s plans for Atlas V launch services. It is subject to change as Atlas V development progresses, and will be revised peri- odically. Potential users of Atlas V launch service are encouraged to contact the offices listed below to obtain the latest technical and program status information for the Atlas V development.

Building and Maintaining the International Space Station (ISS)
/ Building and maintaining the International Space Station (ISS) is a very complex task. An international fleet of space vehicles launches ISS components; rotates crews; provides logistical support; and replenishes propellant, items for science experi- ments, and other necessary supplies and equipment. The Space Shuttle must be used to deliver most ISS modules and major components. All of these important deliveries sustain a constant supply line that is crucial to the development and maintenance of the International Space Station. The fleet is also responsible for returning experiment results to Earth and for removing trash and waste from the ISS. Currently, transport vehicles are launched from two sites on transportation logistics Earth. In the future, the number of launch sites will increase to four or more. Future plans also include new commercial trans- ports that will take over the role of U.S. ISS logistical support.

Launch Vehicle Control Center Architectures
Launch Vehicle Control Center Architectures Michael D. Watson1, Amy Epps2, and Van Woodruff3 NASA Marshall Space Flight Center, Huntsville, AL 35812 Michael Jacob Vachon4 NASA Johnson Space Center, Houston, TX 77058 Julio Monreal5 European Space Agency, Launchers Directorate, Paris, France Marl Levesque6 United Launch Alliance, Vandenberg AFB and Randall Williams7 and Tom McLaughlin8 Aerospace Corporation, El Segundo, CA 90245 Launch vehicles within the international community vary greatly in their configuration and processing. Each launch site has a unique processing flow based on the specific launch vehicle configuration. Launch and flight operations are managed through a set of control centers associated with each launch site. Each launch site has a control center for launch operations; however flight operations support varies from being co-located with the launch site to being shared with the space vehicle control center. There is also a nuance of some having an engineering support center which may be co-located with either the launch or flight control center, or in a separate geographical location altogether. A survey of control center architectures is presented for various launch vehicles including the NASA Space Launch System (SLS), United Launch Alliance (ULA) Atlas V and Delta IV, and the European Space Agency (ESA) Ariane 5. Each of these control center architectures shares some similarities in basic structure while differences in functional distribution also exist. The driving functions which lead to these factors are considered and a model of control center architectures is proposed which supports these commonalities and variations. I. INTRODUCTION Launch vehicles in both Europe and the United States have been operating successfully for several decades. -

Yet very little is known about this story, and about the politics and perceptions that are continuing to drive Japanese efforts despite many outright failures in the indigenization of the industry. This story, therefore, is important not just because of the widespread economic and technological merits of the space launch vehicles sector which are considerable. It is also important because it speaks directly to the ongoing debates about the Japanese developmental state and, contrary to the new wisdom in light of Japan's recession, the continuation of its high technology policy as a whole. -
