ANS reports on the activities of a\nworldwide group of Amateur Radio operators who share an active interest in\ndesigning, building, launching and communicating through analog and digital\nAmateur Radio satellites.\n\nPlease send any amateur satellite news or reports to:\n\[email protected]\n\nIn this edition:\n* Please Do Not Use AO-51 While the Satellite is in Eclipse\n* Maryland-DC PICetSat Balloon Launch on May 29\n* AMSAT Videos From Dayton Hamvention\n* Downlink Signal Successfully Received From Venus-bound UNITEC-1\n* Report on ARISS Contact at the National Air and Space Museum\n* AMSAT-DL Symposium and AGM\n* NASA Listens One More Time for Phoenix\n* ARISS Status - 17 May 2010\n\n\nSB SAT @ AMSAT $ANS-143.01\nPlease Do Not Use AO-51 While the Satellite is in Eclipse\n\nAMSAT News Service Bulletin 143.01\n  From AMSAT HQ SILVER SPRING, MD.\nMay 23, 2010\nTo All RADIO AMATEURS\nBID: $ANS-143.01\n\nAfter a brief outage on May 16 the AO-51 Command Team has turned\nthe repeater back on on AO-51, including the 67 Hz PL mode. The\nCommand Team has a favor to ask of our Southern Hemisphere users,\nincluding those in South America, Southern Africa, Australia, and\nNew Zealand:\n\nPlease avoid using AO-51 while the satellite is eclipsed.\n\nMost tracking programs indicate illuminated or eclipsed states, and\nit can always be found by whether the footprint of the satellite is\ncrossing or in contact with the footprint of the sun. Generally this\nis occurring when the satellite is South of 30 degrees South latitude\nat present. AO-51 eclipses are predicted to reach almost 20 minutes\nby July 2010.\n\nAMSAT-NA VP of Operations, Drew Glasbrenner, KO4MA said, \"I realize\nthis is a large favor to ask, but the alternative right now is moving\nto a scheduled type operation, which I would like to avoid. Please pass\nthis to your friends, other users you know, and your national satellite\nemail lists and forums.\"\n\nFor this summer eclipse season, the eclipsed periods are while AO-51 is\nover mostly unoccupied Antarctica and surrounding areas. This means when\nthe batteries alone are supporting the transmitter there are not likely\nto be any users. The power management software combined with the PL,\nshould mean the satellite's batteries can be protected from over-discharge,\nwhile still providing the strongest possible downlink signal and highest\npossible availability.\n\nObservations from the southern hemisphere while entering and leaving\neclipse are very helpful. Post your reports on the AMSAT-BB or e-mail\nyour report to the AO-51 Control Team via [email protected]. AO-51\noperators also monitor the Live OSCAR Satellite Status page\n(http://oscar.dcarr.org/). Analysis of AO-51's Whole Orbit Data (WOD)\nfiles shows the distribution of the satellite's users.\nSee: http://tinyurl.com/2ehbxv5\n\nIf the eclipse periods get too long too fast the repeater may shut off\ndue to a low battery voltage watchdog. If this happens, please email\nDrew directly via [email protected].\n\nRead the latest AO-51 Control Team News at:\nhttp://www.amsat.org/amsat-new/echo/CTNews.php\n\n[ANS thanks Drew, KO4MA, for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-143.02\nMaryland-DC PICetSat Balloon Launch on May 29\n\nAMSAT News Service Bulletin 143.02\n  From AMSAT HQ SILVER SPRING, MD.\nMay 23, 2010\nTo All RADIO AMATEURS\nBID: $ANS-143.02\n\nIf you're in the Washington DC - Maryland area you're invited to join\nPat Kilroy, N8PK for a PICetSat Lite balloon launch on Saturday, May 29\nat about 10:00 AM EDT.\n\nPat says the launch site can be any place in Carroll County, Maryland.\nCoordination will be on the 145.410 MHz K3PZN/R machine in Westminster,\nMD.

The contact was part of their parti-\ncipation in the annual Lockheed Martin Space Day event.\n\nFifteen Boy Scouts from Troop 417 of Waldorf, MD were given the\nopportunity to speak directly to astronaut Tracy Caldwell Dyson,\nKF5DBF, aboard the International Space Station (ISS) via amateur\nradio.  The contact was facilitated via ground station VK4KHZ in\nAustralia.\n\nEach scout was able to ask at least one question during the nearly\n10 minute contact window.  During the whole program audience members\nwere able to watch a real time satellite track of the ISS on a large\nvideo monitor beside the stage.\n\nThe program was introduced by astronaut Dan Tani, KD5DXE, himself\nhaving recently returned from four months aboard the ISS.  On hand\nto locally MC the event was Dave Taylor, W8AAS.  At the controls of\nthe sound system and the telebridge interface was Bob Curran, KE3GG.\nThe coordinator of the Boy Scout participation in the program was\nBob Davidson, KB3KOW.\n\nLocated a short distance left of the stage where the ARISS contact\nwas taking place, AMSAT had a large display table showcasing amateur\nradio and amateur radio satellites.  In addition to fielding questions\nabout amateur radio and explaining the various satellite samples on\ntheir table, they also had an example of the amateur radio antennas\ninstalled on the ISS and were running a video explaining the ARISS\nprogram on a large video monitor.\n\n[ANS thanks Jim Cross, WI3N; Dave Taylor, W8AAS; and Bob Curran,\n  KE3GG for the above information]\n\n/EX\n\n\n\n\nSB SAT @ AMSAT $ANS-143.06\nAMSAT-DL Symposium and AGM\n\nAMSAT News Service Bulletin 143.06\n  From AMSAT HQ SILVER SPRING, MD.\nMay 23, 2010\nTo All RADIO AMATEURS\nBID: $ANS-143.06\n\nThe SouthGate ARC web site carried a summary of the The 2010 Symposium\nand AGM of AMSAT-DL that took place on April 24 in the Amateur Radio\nfacility at Bochum with its spectacular 20 metre dish.\n\nThe Symposium was told that a successor to the COMPASS-1 CubeSat will\nbe built.
