SB SPACE @ ARL $ARLS028 ARLS028 KB5UAC/Mir activity ZCZC AS28 QST de W1AW Space Bulletin 028 ARLS028 From ARRL Headquarters Newington, CT August 14, 1997 To all radio amateurs SB SPACE ARL ARLS028 ARLS028 KB5UAC/Mir activity US astronaut Mike Foale, KB5UAC, continues to be sporadically active on Amateur Radio from the Russian Mir space station. Foale has been using 145.985 MHz while over the US, and the 145.200/800 MHz split pair elsewhere. In a recent packet bulletin, Foale also said he expects his new Mir 24 crewmates, Anatoli Solovev and Pavel ''Pasha'' Vinogradov, to be active on the radio ''once they are settled in.'' The new crew members arrived August 7 aboard the ailing Mir to replace the Mir 23 contingent of Vasily Tsibliev and Alexander Lazutkin, who returned to Earth August 14. Foale will remain aboard Mir until September. ''We are conducting handover activities now,'' Foale related in his message. He said the team will prepare for a so-called ''internal space walk'' on August 20 to relocate power cables from the damaged Spektr module to Mir's Core module. A decision on whether Foale would get a chance to participate in a later space walk in September was pending this week. The Mir crew has been attempting to clear up vexing problems with its onboard oxygen-generation system. ''Lots to do here,'' Foale said in his hurried posting. ''I try to monitor each day.'' Foale has been experiencing problems with his TNC, which has been losing messages. A new TNC was to have been delivered along with the Mir 24 crew members, but that did not happen. NASA, meanwhile, reports that Foale's scheduled replacement, astronaut Dave Wolf, KC5VPF, is undergoing intensive training in Russia in preparation for swapping places with Foale in late September.
