SB SPACE @ ARL $ARLS004 ARLS004 Ham radio on STS-76 ZCZC AS12 QST de W1AW Space Bulletin 004 ARLS004 From ARRL Headquarters Newington, CT March 13, 1996 To all radio amateurs SB SPACE ARL ARLS004 ARLS004 Ham radio on STS-76 Mission managers at the NASA Kennedy Space Center have announced March 21 as the official launch date for the Space Shuttle Atlantis, and mission STS-76. The mission marks the third time the shuttle will dock with the Russian Mir Space Station. The astronauts are also planning to conduct Amateur Radio activities as part of the Shuttle Amateur Radio EXperiment (SAREX). Five student groups have been selected to make scheduled radio contacts with the crew. The shuttle will also carry a SPACEHAB laboratory, providing the astronauts with a working environment to conduct microgravity research and development, and to help resupply Mir. The astronauts may find time to make contacts with the amateur community and their own families. All of the contacts will be 2-meter FM voice, using the shuttle's VHF Mir-docking radio. Frequencies, call signs and general operating information can be obtained from the new ARRL SAREX World Wide Web site at http://www.arrl.org/sarex/. The following pre-launch Keplerian elements can be used by most computer tracking software to predict the ground track of the shuttle. The elements are based on a scheduled launch of March 21 at 0835 UTC. Thanks to Ken Ernandes, N2WWD, for the following elements which were found on the AMSAT Web site at http://www.amsat.org.
