  • The Aerospace Update
    The Aerospace Update Dec. 28, 2017 Top 2017 Space Images Video Credit: NASA SpaceX Concludes 2017 With Fourth Iridium Next launch SpaceX closed out its most successful year to date Dec. 22nd with the launch of 10 satellites for mobile satellite services operator Iridium, notching a personal best of 18 launches in a single year. The Falcon 9 mission, which took off from Vandenberg Air Force Base in California at 8:27 p.m. Eastern in an instantaneous launch window, was the fourth of eight missions for Iridium, carrying the McLean, Virginia- based operator’s second generation satellites, called Iridium Next. In what now is considered a rarity, SpaceX opted not to recover the rocket’s first stage, instead letting the booster fall into the Pacific Ocean. Video Credit: SpaceX Source: Caleb Henry @ SpaceNews.com Zenit Rocket Launches AngoSat-1 but Ground Control Loses Contact A Russian-Ukrainian Zenit rocket was launched on Tuesday, December 26th, with the aim of delivering into orbit Angola’s first satellite, known as AngoSat-1. However, it appears that contact with the spacecraft was lost after its deployment into orbit. The booster lifted off from Site 45/1 at the Baikonur Cosmodrome in Kazakhstan. Tuesday’s launch marked the first Zenit flight in more than two years when it orbited the Elektro-L № 2 weather satellite for Roscosmos. The rocket returned to flight despite fears that the Russian-Ukrainian conflict, which started in 2014, would kill any joint efforts between these two countries.

Through the years, Italy and the US have a strong and wide... [coughing] ...both as friends and allies. We share the same values and we work side by side on many subjects... [coughing] Space represents one of the fields where our cooperation has proved to be remarkably successful. Since the launch of San Marco satellite from Wallops Island back in 1964, our countries have forged a long-standing cooperation. Let me recall that in a few weeks’ time that astronaut Tom Pesquet, will once again embark upon a long-duration mission to the International Space Station. The main criteria for the success has always been, and I have no doubt it will continue to be, the solid partnership between NASA and Italian Space Agency, ASI. Today's presence of President and Professor of Roberto Battiston whom I work with while come here to the Embassy, perfectly analyzes the special relationship.

    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.
