USAF Sat Cat: 26694 . COSPAR: 2001-005A. Apogee: 35,801 km (22,245 mi). Perigee: 35,773 km (22,228 mi). Inclination: 0.10 deg. Period: 1,436.10 min.

  Sicral, (Sistema Italiana de Communicazione Riservente Allarmi) was a communications satellite for the Italian defense ministry's procurement division, the Segretariato Generale della Difesa's Direzione Nazionale degli Armamenti. Sicral was built by Alenia Aerospazio and derived from the Italsat series. Its mass was 2596 kg full, 1253 kg dry and it carried a liquid apogee engine. The 3.3 kW, 3.4 m x 4.9 m, triaxially-stabilized spacecraft carried a total of nine transponders in the SHF-, UHF-, and EHF-bands to enable secure communications after parking over 16.2 deg-E longitude. Positioned in geosynchronous orbit at 16 deg E in 2001 As of 26 August 2001 located at 16.27 deg E drifting at 0.004 deg W per day. As of 2007 Mar 9 located at 16.34E drifting at 0.018E degrees per day.

• Artemis - . Mass: 3,105 kg (6,845 lb). Nation: Europe. Agency: ESA. Manufacturer: Alenia. Class: Technology. Type: Communications technology satellite. Spacecraft: Italsat. USAF Sat Cat: 26863 . COSPAR: 2001-029A. Apogee: 32,586 km (20,247 mi). Perigee: 32,451 km (20,164 mi). Inclination: 1.10 deg. Period: 1,272.40 min.

  Artemis was a European Space Agency satellite designed to test new communications technologies. The Ariane 510 vehicle failed to reach its correct orbit. The solid boosters and main stage worked as planned and put the EPS upper stage in the planned near-suborbital trajectory. The EPS stage then fired but the Aestus engine failed to reach full thrust and cut off 1 minute early. Instead of the planned 858 x 35853 km orbit, only a 592 x 17528 km orbit was reached. The 3.1 tonne (with fuel), 2.5 kW spacecraft carried two pairs of ion engines and had adequate xenon propellant for those engines to reach geosynchronous altitude. This was the first ever rescue of a satellite mission using electric propulsion. The satellite reached its operational orbit in 31 January 2003.using the four German RITA electric xenon thrusters. Artemis could then function as originally planned, as there remained sufficient chemical propellant for 10 years' operation. Artemis was to provide voice and data communications between mobile phones in Europe and North America, and act as a relay satellite between low-Earth orbiters and ground stations. Eventually, as part of the planned EGNOS system (to be operational by about 2010) it was to provide navigation/location determination as an independent European counterpart to the GPS and GLONASS fleets. As of 2007 Mar 11 located at 21.40E drifting at 0.001W degrees per day.

  Launch delayed from August 27. Atlantic Bird was a European (EUTELSAT) geostationary communications spacecraft. The 2.7-ton (1550 kg dry with 1150 propellant), 5 kW satellite was to provide voice, video, and Internet services to Europe and the eastern part of America through its 24 transponders after being parked over 12.5° W. As of 2007 Mar 10 located at 12.49W drifting at 0.006W degrees per day.
