SB NEWS @ AMSAT $SPC0202 * SpaceNews 02-Feb-98 * BID: $SPC0202 ========= SpaceNews ========= MONDAY FEBRUARY 2, 1998 SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is published every week and is made available for non-commercial use. * STS-89 MISSION NEWS * ======================= Space Shuttle mission STS-89 came to an end on 31-Jan-98 at 2235 UTC with a smooth landing on runway 15 at the Kennedy Space Center (KSC) in Flordia. The primary objective of this flight was to rendezvous and dock with the Russian space station Mir and perform a crew exchange of U.S. astronaut David Wolf from Mir with Andrew Thomas from the shuttle. Andrew Thomas is the last U.S. astronaut assigned to visit the Mir complex. Endeavour's next mission will carry the U.S. Node Module to support the construction of the International Space Station (ISS) in July. [Info via the ISIR Newsline Digest] * MIR 25 CREW LAUNCHED * ======================== French cosmonaut Leopold Eyharts and two Russians, Talgat Musabayev and Nikolai Budarin, were launched to the Russian space station Mir from the Baikonur Cosmodrome aboard a Soyuz booster on 29-Jan-98 at 1633 UTC. The three man crew aboard Soyuz TM-27, known as Mir 25, docked on 31-Jan-98. Musabayev and Budarin will replace the current Russian crew aboard Mir, Anatoly Solovyev and Pavel Vinogradov, who will return to earth in a few weeks with Eyharts. Soon after the Soyuz lift-off, the U.S. space shuttle Endeavour undocked from Mir after spending a few days linked to the complex to retrieve U.S. astronaut David Wolf, and leave astronaut Andrew Thomas and supplies for the next few months. Thomas is scheduled to remain aboard Mir until May. He is the last of a series of U.S. astronauts who have been aboard Mir: Norm Thagard (Feb 95 - Jun 95) Shannon Lucid (Mar 96 - Sep 96) John Blaha (Sep 96 - Jan 97) Jerry Linenger (Jan 97 - May 97) Mike Foale (May 97 - Sep 97) David Wolf (Sep 97 - Jan 98) Andrew Thomas (Jan 98 - Present) [Info via the ISIR Newsline Digest] * SKN '98 BEST FIST WINNERS * ============================= Ray, W2RS, extends his thanks to all who participated in AMSAT-NA's OSCAR SKN '98. Although activity was down from prior years due to the loss of RS-10, the temporary loss of Mode K on RS-12 and the unfavorable position of AO-10, a good time was had by those who took part. Once again our first-place winner was Rusty, NM1K, who received five separate nominations. Two more 1998 winners also had been nominated in previous years: G3RWL and W1NU. Joining the winners' circle for the first time in 1998 were AG2R, K4IPH and VE5SWL. Heartiest congratulations to all. * AMSAT-OSCAR-10 STATUS * ========================= Stacy Mills W4SM, reports that AO-10's signals are improving and are quite strong even at apogee, except for periods of deep QSB, which can be largely corrected by changing antenna polarization. These findings suggest strongly that AO-10 has switched (glitched) itself to its hi-gain antennas. There is probably a component of Z-axis wobble accounting for the QSB. As illumination has improved, the FMing heard earlier appears to have disappeared. The switch to hi-gains would also explain the often poor signals near perigee when the squint angle is particularly bad. AO-10 is currently experiencing long (90 minute) solar eclipses with onset after apogee. The MA of onset will continue to increase and the length of the eclipse will continue to decrease until the period ends on 23-Feb-98. AO-10's apogee has moved into the northern hemisphere (ArgP > 180). Apogee will continue to rise higher to the north for the rest of 1998, peaking at ArgP = 270 in December. Stacey Mills has updated his Web page to include discussions of AMSAT-OSCAR-10's status as well as smoothed Keplerian elements for the spacecraft.

Limebear, G3RWL, on behalf of AMSAT-UK, is requesting comments regarding the construction and funding of future OSCAR satellites carrying Mode A (145 MHz UP, 29 MHz DOWN) communications transponders. Based on comments and feelings expressed by some satellite users, it is believed that: 1) There is a need for Mode-A satellites for new satellite operators to train on, as well as for those amateurs who prefer analogue rather than digital operations; and 2) The present supply of Mode-A satellites is fast decreasing with the demise of RS-10/11, problems commanding RS-12/13, battery troubles with RS-15, and the non-availability of RS-16. No Mode-A spacecraft has been produced by a Western group for the past 20 years (Oscar-8 in 1978). AMSAT-UK is giving some consideration to this state of affairs but, before they go further, they need to determine whether a new Mode-A package would a) be wanted; b) be used; and c) be supported. In other words, do satellite operators (ie: YOU) want it to happen? Is it worth someone's time and effort to design, produce, and launch such a satellite? How many people would use a new Mode-A spacecraft? It would be pointless to spend several hundred thousand dollars if it only attracted a few hundred users (so the cost is 1000 dollars per user). Would YOU use it? This several hundred thousand dollars doesn't just appear magically. The money has to be raised by satellite operators (ie: YOU). Would you give your own money to a group who promised to develop and launch a Mode-A transponder?
