It is a prediction of who will have the greatest competitive advantage in the commercial market over the next 25 years, based on historical analogy. Background information on Russia, China, Japan, the United States and the European Space Agency, including the launch vehicles and launch services each provides, is covered. The new prospect of space platforms is also investigated. 2 Table of Contents Abstract: ...................................................................................................... 2 Table of Contents ......................................................................................... 3 Introduction ................................................................................................. 5 Literature Review ...................................................................................... 5 Project -
The Wittelsbach-Graff and Hope Diamonds: Not Cut from the Same Rough
THE WITTELSBACH-GRAFF AND HOPE DIAMONDS: NOT CUT FROM THE SAME ROUGH Eloïse Gaillou, Wuyi Wang, Jeffrey E. Post, John M. King, James E. Butler, Alan T. Collins, and Thomas M. Moses Two historic blue diamonds, the Hope and the Wittelsbach-Graff, appeared together for the first time at the Smithsonian Institution in 2010. Both diamonds were apparently purchased in India in the 17th century and later belonged to European royalty. In addition to the parallels in their histo- ries, their comparable color and bright, long-lasting orange-red phosphorescence have led to speculation that these two diamonds might have come from the same piece of rough. Although the diamonds are similar spectroscopically, their dislocation patterns observed with the DiamondView differ in scale and texture, and they do not show the same internal strain features. The results indicate that the two diamonds did not originate from the same crystal, though they likely experienced similar geologic histories. he earliest records of the famous Hope and Adornment (Toison d’Or de la Parure de Couleur) in Wittelsbach-Graff diamonds (figure 1) show 1749, but was stolen in 1792 during the French T them in the possession of prominent Revolution.

That has now changed due to a number of factors, among the more dominant being economics, advanced and improved technologies and national imperatives.

Classification of Geosynchronous Objects Issue 12
EUROPEAN SPACE AGENCY EUROPEAN SPACE OPERATIONS CENTRE GROUND SYSTEMS ENGINEERING DEPARTMENT Space Debris Office CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS ISSUE 12 by R. Choc and R. Jehn Produced with the DISCOS Database February 2010 ESOC Robert-Bosch-Str. 5, 64293 Darmstadt, Germany 3 Abstract This is a status report on geosynchronous objects as of the end of 2009. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring (here defined as orbits with mean motion between 0.9 and 1.1 revolutions per day, eccentricity smaller than 0.2 and inclination below 30 deg) is analysed. From 1161 objects for which orbital data are available, 391 are controlled inside their longitude slots, 594 are drifting above, below or through GEO, 169 are in a libration orbit and 7 whose status could not be determined. Furthermore, there are 77 uncontrolled objects without orbital data (of which 66 have not been catalogued). Thus the total number of known objects in the geostationary region is 1238. During 2009 twenty-one spacecraft reached end-of-life. Eleven of them were reorbited following the IADC recommendations, one spacecraft was reorbited with a perigee of 225 km - it is not yet clear if it will enter the 200-km protected zone around GEO or not -, six spacecraft were reorbited too low and three spacecraft did not or could not make any reorbiting manouevre at all and are now librating inside the geostationary ring. If you detect any error or if you have any comment or question please contact R¨udiger Jehn European Space Operations Center Robert-Bosch-Str. -

GB-ASTRA 3B-Comsatbw-21Mai V
A BOOST FOR SPACE COMMUNICATIONS SATELLITES For its first launch of the year, Arianespace will orbit two communications satellites: ASTRA 3B for the Luxembourg-based operator SES ASTRA, and COMSATBw-2 for Astrium as part of a contract with the German Ministry of Defense. The choice of Arianespace by leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Because of its reliability and availability, the Arianespace launch system continues to set the global standard. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads. Over the last two decades, Arianespace and SES have developed an exceptional relationship. ASTRA 3B will be the 33rd satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to have chosen the European launcher. SES ASTRA operates the leading direct-to-home TV broadcast system in Europe, serving more than 125 million households via DTH and cable networks. ASTRA 3B was built by Astrium using a Eurostar E 3000 platform, and will weigh approximately 5,500 kg at launch. Fitted with 60 active Ku-band transponders and four Ka-band transponders, ASTRA 3B will be positioned at 23.5 degrees East. It will deliver high-power broadcast services across all of Europe, and offers a design life of 15 years. Astrium chose Arianespace for the launch of two military communications satellites, COMSATBw-1 and COMSATBw-2, as part of a satellite communications system supplied to the German Ministry of Defense. The first satellite in this family, COMSATBw-1, was launched by Arianespace in October 2009. -
Positioning: Drift Orbit and Station Acquisition
Orbits Supplement GEOSTATIONARY ORBIT PERTURBATIONS INFLUENCE OF ASPHERICITY OF THE EARTH: The gravitational potential of the Earth is no longer µ/r, but varies with longitude. A tangential acceleration is created, depending on the longitudinal location of the satellite, with four points of stable equilibrium: two stable equilibrium points (L 75° E, 105° W) two unstable equilibrium points ( 15° W, 162° E) This tangential acceleration causes a drift of the satellite longitude. Longitudinal drift d'/dt in terms of the longitude about a point of stable equilibrium expresses as: (d/dt)2 - k cos 2 = constant Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF EARTH ASPHERICITY VARIATION IN THE LONGITUDINAL ACCELERATION OF A GEOSTATIONARY SATELLITE: Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF SUN & MOON ATTRACTION Gravitational attraction by the sun and moon causes the satellite orbital inclination to change with time. The evolution of the inclination vector is mainly a combination of variations: period 13.66 days with 0.0035° amplitude period 182.65 days with 0.023° amplitude long term drift The long term drift is given by: -4 dix/dt = H = (-3.6 sin M) 10 ° /day -4 diy/dt = K = (23.4 +.2.7 cos M) 10 °/day where M is the moon ascending node longitude: M = 12.111 -0.052954 T (T: days from 1/1/1950) 2 2 2 2 cos d = H / (H + K ); i/t = (H + K ) Depending on time within the 18 year period of M d varies from 81.1° to 98.9° i/t varies from 0.75°/year to 0.95°/year Orbits Supplement GEO PERTURBATIONS (CONT'D) INFLUENCE OF SUN RADIATION PRESSURE Due to sun radiation pressure, eccentricity arises: EFFECT OF NON-ZERO ECCENTRICITY L = difference between longitude of geostationary satellite and geosynchronous satellite (24 hour period orbit with e0) With non-zero eccentricity the satellite track undergoes a periodic motion about the subsatellite point at perigee. -
