SB SPACE @ ARL $ARLS006 ARLS006 SAREX To Fly In June ZCZC AS85 QST de W1AW Space Bulletin 006 ARLS006 >From ARRL Headquarters Newington, CT May 26, 1995 To all radio amateurs SB SPACE ARL ARLS006 ARLS006 SAREX To Fly In June The Shuttle Amateur Radio EXperiment, or SAREX, will be carried on the 100th US human space mission when the Space Shuttle Discovery launches on June 8, 1995 at 1326 UTC. The mission is designated STS-70, and the crew includes one Amateur Radio-licensed astronaut, Mission Specialist Donald A. Thomas, KC5FVF. The crew has scheduled voice contacts with 8 school groups in the US and one in Argentina. Landing is targeted for June 16 at 1136 UTC at the Kennedy Space Center in Florida. On this mission, the SAREX hardware will be flown in configuration C which includes 2 meter FM voice and packet. Amateurs should use the usual frequency set to make random SAREX contacts. The astronauts will operate split, transmitting and receiving on separate frequencies. Please do not transmit on the shuttle's downlink frequency. The downlink is your receiving frequency. The uplink is your transmitting frequency. The FM voice downlink is 145.55 MHz. The FM voice uplinks are 144.91, 144.93, 144.95, 144.97 and 144.99 MHz. The crew will not favor any of the uplink frequencies, so your ability to communicate with SAREX will be the ''luck of the draw.'' To avoid causing interference to other stations, transmit only when the shuttle is within range and when the SAREX station is on the air. The crew will use KC5FVF as the primary voice call sign. On packet, use W5RRR-1 to log a contact on the SAREX ROBOT.

Include the mission number, date, time in UTC, frequency and mode in your report. You must also include a self-addressed stamped business-sized envelope if you wish to receive a card. The Sterling Park Amateur Radio Club in Sterling, VA has generously volunteered to manage the cards for this mission. The flight will highlight the deployment of a sixth Tracking and Data Relay Satellite. Once deployed, an engine on the satellite will boost it into a geostationary orbit. The TDRS System provides NASA with communication and tracking capability to meet its mission support requirements. SAREX will also be carried on mission STS-71, which is scheduled for no earlier than June 23. During that mission, the Shuttle Atlantis will rendezvous and, for the first time, dock with the Russian Space Station Mir. The shuttle will carry two new Mir crew members (Mir 19) to the station, and return to Earth with the three Mir 18 crew members, including US astronaut Norm Thagard.
