SB SPACE @ ARL $ARLS005 ARLS005 Phase 3-D update ZCZC AS13 QST de W1AW Space Bulletin 005 ARLS005 From ARRL Headquarters Newington, CT June 11, 1996 To all radio amateurs SB SPACE ARL ARLS005 ARLS005 Phase 3-D update Ariane 5 failure could affect Phase 3-D launch The spectacular failure of an Ariane 5 launch vehicle, the same type of rocket that's scheduled to carry the Phase 3-D satellite aloft later this year, may have an impact on the Phase 3-D program. The rocket, on its maiden operational test, had to be destroyed June 4 by ground-based command 40 seconds into the flight at an altitude of about 12,000 feet (4000 meters) when it appeared to veer off course. The launch was from the European Space Agency's Kourou launch facility in French Guiana, South America. Ariane 501 carried a group of four scientific satellites known as ''Cluster'' which were destroyed as well. No Amateur Radio satellites were aboard. The AMSAT Phase 3-D spacecraft, now under construction, is manifested on the second flight of the Ariane 5 series (Ariane 502) which, according to ESA's latest schedule, is to be launched in October of this year. AMSAT officials say it's too early to know what effect the Ariane 501 failure will have on the 502 schedule, the possible Phase 3-D launch date, or the vehicle on which it will ride. But they do not rule out a schedule that extends beyond the re-entry of AO-13 into the Earth's atmosphere. AMSAT-DL President Karl Meinzer, DJ4ZC, and AMSAT-NA President Bill Tynan, W3XO, expressed their sadness on hearing the news. In a joint statement they said, ''We at AMSAT have enjoyed a mutually beneficial relationship with ESA for over 15 years, and we are, quite naturally, distressed to hear of this unfortunate occurrence.'' They noted that except for the RS and Fuji satellites, all successful Amateur Radio satellite launches since the early 1980s have been on Ariane vehicles. Both men expressed confidence that the ESA team will overcome this setback and develop a successful launch vehicle. DJ4ZC and W3XO said they stand together in anticipating a successful launch of Phase 3-D on a future Ariane mission. NNNN /EX
