SB SAREX @ AMSAT $STS-71.001 STS-70 SAREX Mission Information The next Space Shuttle mission with the Shuttle Amateur Radio Experiment (SAREX) payload on-board is currently slated for launch on Thursday July 13 at 13:41 UTC. The STS-70 Space Shuttle Discovery mission will carry Amateur Radio operators Don Thomas, KC5FVF, and Nancy Curie, KC5OZX, into a 28.5 degree inclination orbit for an 8 day mission. The primary objective of this flight is to deploy the last spacecraft in the current series of the Tracking Data Relay Satellite System (TDRSS). 10 schools from the U.S. and Argentina have scheduled ham radio contacts with the astronauts. Several of these school group contacts will be performed using AMSAT's worldwide network of telebridge stations. The telebridge allows students to talk to the Astronauts through a remote ground station that is linked to the school though a phone bridge. The Goddard Amateur Radio Club, WA3NAN expects to retransmit some of these school contacts as part of their Shuttle retransmission activities. A limited number of schools who wish to "eavesdrop" on the STS-70 school group contacts via a listen only phone connection are encouraged to send e-mail to Frank Bauer, KA3HDO, with your request. Your request should include an explanation of how you are going to use this listen only dialog in your classroom setting. Mr. Bauer's e-mail address is ka3hdo@amsat.org.
