SB SPACE @ ARL $ARLS025 ARLS025 Shuttle contacts PRC ZCZC AS25 QST de W1AW Space Bulletin 025 ARLS025 From ARRL Headquarters Newington, CT July 15, 1997 To all radio amateurs SB SPACE ARL ARLS025 ARLS025 Shuttle contacts PRC It didn't come off without a hitch, but the crew aboard the shuttle Columbia during mission STS-94 in July nonetheless managed a first for the Shuttle Amateur Radio EXperiment (SAREX) program. On Monday, July 14, the shuttle crew spoke with students at Tsinghua University. The contact was via a telebridge link with Gordon Williams, VK6IU, in Western Australia. The successful QSO marked the first SAREX contact with a school in the People's Republic of China. On the first scheduled orbit for the Tsinghua University contact, the designated crew member, Payload Specialist Roger Crouch, was busy with primary mission duties. The SAREX ground team stayed up late and managed a successful QSO on the following orbit. There were 30 people in the Tsinghua University audience, along with Chinese television, Chinese government officials, and some Chinese IARU representatives. David Chang, BY1QH, coordinated the contact at the university's end. Despite some rough copy, the contact went ''very well'' with 10 questions asked and answered, according to SAREX Principal Investigator Matt Bordelon, KC5BTL. The Chinese contact was one of 17 scheduled SAREX QSOs the STS-94 crew members completed during their 16-day mission. Overall, ham radio had a very prominent role in the mission, which not only completed all of the scheduled SAREX contacts with school groups but made numerous random QSOs with earthbound hams. Aboard the shuttle were Jim Halsell, KC5RNI, the mission commander; Janice Voss, KC5BTK; and Donald Thomas, KC5FVF, who set up the orbiting ham shack and completed 19 random contacts before the ''official'' scheduled test pass. Toward the end of the mission, the Columbia crew averaged three dozen or so random voice contacts per day during the 16-day mission. The packet robot was activated nine days into the mission. The other SAREX schools on mission STS-94 were: Alvin C. York Agricultural Institute, Jamestown, Tennessee; Center Street School, El Segundo, California; Crittenden Middle School, Mountain View, California; Discovery Place Inc, Charlotte, North Carolina; Du Bois Middle School, Du Bois, Pennsylvania; Dunn's Corners Elementary School, Westerly, Rhode Island; Edgewater High School, Orlando, Florida; Foursquare Radio Amateur Youth, Oxnard, California; Ione Junior High School, Jackson, California; Lawrence Intermediate School, Lawrenceville, New Jersey; Lexington Traditional Magnet School, Lexington, Kentucky; Mountain View Elementary School, Prescott Valley, Arizona; Public School No 9, New York, New York; Robert J. Burch Elementary School, Tyrone, Georgia; S.J. Davis Middle School, San Antonio, Texas; and Yeso Elementary School, Artesia, New Mexico. STS-94 marked the 24th SAREX mission. The mission--a ''refly'' of the aborted STS-83 mission in April--carried the same crew members and the microgravity science lab payload. The Columbia crew will stow the SAREX equipment on July 16.
