At least one has maneuvered into a higher orbit. This might perhaps be an advanced version of the Navy's White Cloud ocean surveillance system, which is known to use a mother satellite with several auxiliaries. Heavyweight aircraft of the month: British Aerospace and the Soviet Ministry of Aviation Industry propose reviving Hotol [!], using an Antonov Mriya to carry a rocket-powered version of Hotol aloft, avoiding the need for an advanced airbreathing engine. Estimated payload to a low near-equatorial orbit is 7 tons, and costs are estimated to be about $2000/kg, roughly a third of that for Ariane 5. Re-engining Mriya with Rolls-Royce engines is being kept as a reserve possibility against the chance that Hotol will gain weight in development. The Soviets are investigating the carry and separation aspects, and also the possibility of using Soviet oxyhydrogen engines in Hotol. BA is looking into the modified Hotol, plus support and economics. Both sides consider it promising, and estimate an operational date circa 2000 if all goes well and funding (perhaps $4.6G) can be found. Magellan under control after early mishaps, with causes still being investigated. Japan's BS-3A broadcastsat has lost one of its four power supply sectors, the resulting 1.1kW power output being only marginally adequate for its full mission. The solar arrays appear to have deployed fully and on schedule Aug 31, and the nature of the failure is somewhat mysterious. This may be a headache for Japan's broadcasting plans, as BS-2 is near the end of its life and the next BS-3 will not go up until next summer, even assuming that it is not delayed for redesign of power systems. Astro launch scrubs Sept 5 due to yet another hydrogen leak. Another attempt will be made Sept 17; win or lose [the latter], that will push the Ulysses launch several days past the opening of its window Oct 5 unless NASA's normal three-week gap for data assessment is waived to give Ulysses as much margin as possible. [I believe the gap was waived but Ulysses was late anyway, due to some other problem. However, it's on its way.] NASA worried about a leak in one of Discovery's cooling systems, as a fix would make it impossible to get Ulysses off this year. Managers hoping that just topping it off before launch will do; the leak is small. [That's what they did.] [That's it for AW&ST; not much news that week.] [18 July Flight International] ESA Council approves the Huygens Titan probe as part of the Cassini mission, and starts work on Artemis and DRS comsat projects. Artemis is a technology test for mobile communications and intersatellite communications, partly as a preliminary for the Data Relay Satellite system, Europe's equivalent of TDRS to support Columbus and Hermes. Artemis will go up in 1994, DRS in 1996 if full funding is authorized next year. Prime contractor for both is Selenia Spazio of Italy. US government tentatively states that it would approve export licenses for US-build satellites being launched on Zenits from Cape York, and for United Technologies to participate in Cape York development. [Don't remember whether AW&ST reported this or not.] [1 Aug F.I.] NASA's B-52 to commence tests of the shuttle drag chute system, to be installed in Endeavour and retrofitted to the earlier orbiters. Japan's NASDA announces plans for an unmanned space tug, for delivering supplies to the Japanese section of the space station and maneuvering other satellites. Test launch possible in 1995. Martin Marietta design bureau, er oops excuse me I mean Martin Marietta Inc, awarded DoD contract to redesign the payload adapter for Titan IV/Centaur. The Titan IV/IUS launches flown so far have revealed much higher levels of shock and vibration than expected. IV/C launches will be delayed. -- "I don't *want* to be normal!" | Henry Spencer at U of Toronto Zoology "Not to worry." | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 18 Nov 90 14:51:33 GMT From: crash!orbit!pnet51!schaper@nosc.mil (S Schaper) Subject: Re: Free flying lab (was: Re: LLNL Astronaut Delivery) It is named...Columbus, just like in my post.

Why do you suppose Lacrosse looks red? I assume they would not have painted it (and if they did, would you paint it a light absorbing color like red?). Are there solar panels that might reflect that color? Interesting. I must admit, in many years of satellite tracking, I don't recall ever having seen a color associated with a satellite, so this is intriguing (I also have faith in Beresford's observations).

Pretty bizarre to think we've come 20 years, with CAD/CAE and materials engineering and we can't build something which was put together in the '60s.

It is published every week and is made available for unlimited distribution. * MARS VISIBILITY * =================== The planet Mars will be visible to those living on the east coast of the United States. The planet will appear as a reddish "star" in the eastern sky. Best viewing will begin around 8:00PM local time. Mars will be closest to Earth on Tuesday, when it will be about 48 million miles from Earth. Viewing should be equally good through early December. * SALYUT-7 NEWS * ================= The presently unused and long abandoned Soviet space station 'Salyut-7' is tumbling uncontrollably and is predicted to re-enter the Earth's atmosphere in mid-January. Attempts to boost the 60 metric ton structure to a higher orbit have failed. Salyut-7 should produce quite a spectacular light show if it re-enters the atmosphere away from sunlight. Here is element set 633 for Salyut-7 as released by NASA on 14-Nov-90: Epoch : 90 318.01787657 Incli : 51.5983 RAAN : 257.2085 Eccn : 3.837E-04 ArgPer : 109.0767 MeanAn : 251.0680 MeanMo : 15.82804120 Decay : 1.11688E-03 Orbit # : 48841 * PACSAT NEWS * =============== Work continues on UO-14 and AO-16. DOVE-1 will be reset shortly after software testing on the other Microsats is complete. * RS-14/RUDAK-2 NEWS * ====================== Reliable sources within the Soviet Union indicate that the launch of RS-14/ RUDAK-2 is now expected to happen on or about November 24, 1990. UA3CR requests the help of radio amateurs all over the world to collect telemetry and send it via packet radio or via a SSB net to him. The first day's worth of telemetry will transmitted via a CW beacon at 20 WPM on 145.822 or on 145.948 MHz SSB and will be vitally important to ground controllers. Later, after ALL systems are working properly on the RUDAK-2 transponder, PSK/BBS/MODE B operations will begin. * TNX QSL! * ============ A special thanks to all those who sent QSLs, cards and letters to SpaceNews: IW1BMJ: Claudio Ariotti, Casale Monferrato, Italy N6TTR : Doc Pagala, French Camp, California, U.S.A.
