SB SPACE @ ARL $ARLS010 ARLS010 Phase 3D update ZCZC AS18 QST de W1AW Space Bulletin 010 ARLS010 From ARRL Headquarters Newington, CT July 31, 1996 To all radio amateurs SB SPACE ARL ARLS010 ARLS010 Phase 3D update AMSAT says the Phase 3D international satellite could launch as early as mid-February, 1997, as a passenger on the next European Space Agency (ESA) Ariane 5 mission, AR 502. ESA said the launch will come ''within the first six months of 1997.'' AMSAT officials now are completing all integration and testing efforts for the Phase 3D satellite in time for the launch, which had been set for this fall. However, the failure of the first Ariane 5 mission in June set back the launch schedule. An ESA board of inquiry blamed a software glitch for the Ariane 501 failure. The latest announcement came July 27 during a joint AMSAT-Germany/AMSAT-North America presentation on Phase 3D's status to the 1996 AMSAT-UK Colloquium at the University of Surrey in England. The decision reaffirming the use of the Ariane launch vehicle followed a series of high-level meetings between AMSAT and ESA officials July 23 and 24. Phase 3D project leader Karl Meinzer, DJ4ZC, AMSAT-DL president, was upbeat about the announcement. Meinzer said AMSAT had been assured that ESA is taking the inquiry board's recommendations to heart ''and are now rolling up their shirtsleeves to correct those deficiencies in time for the Ariane 502 launch next year.'' Meinzer said he's ''very confident'' that ESA will do all to insure a successful launch. AMSAT-NA's Keith Baker, KB1SF, was equally positive about the latest developments for Phase 3D's launch. ''The fact that the investigators were able to use recovered debris and subsequent laboratory analysis to duplicate the exact sequence of events that caused the AR 501 failure gives us renewed confidence for the prospects of a successful launch on AR 502.'' AMSAT-NA President Bill Tynan, W3XO, also viewed the latest launch developments for the Phase 3D satellite as good news. ''However, this still places responsibility for completion and testing of Phase 3D firmly in our court,'' he said. ''We must still finish final integration and testing of the satellite by year's end, conduct the launch campaign, and insure the necessary funds are secured to do so.'' Tynan said even if the launch comes off as planned, the unanticipated delay of a year or more ''translates directly into a critical need for additional funding to insure Phase 3D is complete and flight-ready when ESA tells us it is time to launch.'' The Phase 3D satellite, now under construction by AMSAT, will be the largest, most complex, and most expensive Amateur Radio satellite ever built.
