Also testifying will be the panel's vice chairman, Laurel L. Wilkening. * * * * * * * * * * * * * * * * * * * * * Over 52 million miles from Earth and traveling 73,000 miles per hour, the Ulysses spacecraft has begun a series of radio science experiments, as Earth passes directly between the spacecraft and the sun. The series of special tracking passes to obtain radio science data began last week, in preparation for the December 30 solar opposition, and controllers say the bulk of the radio science passes will continue through Friday. Ulysses' wobble has been eliminated at this point in its orbital trajectory, and contingency plans are being worked out to fly the spacecraft should the wobble return in February or March of this year. A spurious event of unknown origin temporarily affected science experiments aboard Ulysses, December 19th. The glitch, which corrupted the spin rate measurement of the spacecraft, affected three, and possibly four of the spacecraft's nine active experiments. Controllers returned experiments to nominal operation on December 20th, and the cause of the anomaly remains under investigation. * * * * * * * * * * * * * * * * * * * * * * * * * * Over the holidays, Kennedy Space Center technical crews performed annual ground system checks to support Space Shuttle operations. Work continues to replace the launch facility's uninterruptable power system and is expected to be completed within two weeks. The Space Shuttle Discovery will be powered up this afternoon to continue its preparation for launch of the DOD STS-39 mission in March. Discovery's payload bay doors will be opened, and later this week, installation of the Forward Reaction Control System will continue. A high pressure main propulsion test is also scheduled for this week. Meanwhile, Atlantis is scheduled to be powered up Friday and installation of the remote manipulator system "arm" to be used in deploying the Gamma Ray Observatory is scheduled to begin.

Space-Vehicle Aerothermodynamics [W. Berry, J. Haeuser] Discusses ESA's past, present and future activities in the field of aerothermodynamics, a technical discipline embracing classical aerodynamics, thermodynamics and thermochemistry. The aerothermo- dynamics of a number of projects are discussed followed by a discussion of necessary tools and engineering facilities. The article concludes with a summing up of activities designed to get ESA's aerothermodynamics technology ready for the future. Definition des Formes Aerodynamiques d'Hermes [C. Dujarric] (French) The article discusses the shape of Hermes and why it will get that shape. It contains a set of nice windtunnel photographs. Operating Europe's Future In-Orbit Infrastructure [U. Christ, W. Frank, N. Gargir, R. van Holtz] The in-orbit infrastructure will consist of the Columbus Attached Laboratory, the Columbus Free Flying Laboratory, the Hermes Space Plane, the European Polar Platform and the European Data-Relay System. The article describes centralised functions and decen- tralised functions for operating this in-orbit infrastructure and gives a short description of the tasks of each of the centres responsible for these functions, how they will communicate and how planning activities are conducted. The Columbus Free Flying Laboratory - A stepping Stone Towards European Autonomy [J. Collet] The Columbus Free Flying Laboratory will provide Europe with facilities for the support of men in space. It will also be the initial core element of the future manned space infrastructure. The New European Astronauts Centre [A. Ripoll, K. Damian, W. Peeters, F. Rossitto] The article describes selection criteria and procedures as well as training of European astronauts. The training concept and facilities are then described, as well as the organisation of the training. [An Antarctic Crossing as an Analogue for Long-Term Manned Spaceflight [H. Ursin, J.-L. Etienne, J. Collet] The article describes an expedition by a six-man international team that crossed the Antarctic continent. The results of this expedition where used to analyse psychological problems during an international expedition involving prolonged isolation in a hos- tile environment. Giotto's Reactivation and Earth Swingby [T.A. Morley] The article describes the problems encountered during the reacti- vation from hibernationm of Giotto, the Earth-gravity assist manoeuvre to swing Giotto en route to an encounter with comet Grigg-Skjellerup in 1992 and re-hibernation until the encounter in 1992. The Hipparcos Mission - On the Road to Recovery [H. Hassan, K. Clausen, M.A.C. Perryman, J. van der Ha, D. Heger] The article describes the adaptation of the Hipparcos mission to the new constraints imposed by the highly anomalous orbit caused by the failure of the apogee boost motor. Olympus Manoeuvres in Transfer Orbit - An ESA First [J.H.C. Auburn, D. Suen] This article describes the fifteen attitude manoeuvres performed by the Olympus spacecraft to calibrate the four on-board gyros- copes in order to achieve an accurate attitude during the apogee engine firing. The Olympus Utilisation Programme [C.D. Hughes] The article describes the payloads of the Olympus-1 technology satellite (the largest civil communications satellite) and how these payloads are and will be used by commercial and scientific institutions. The 'PAX' Experiment on Olympus [D. Tunbridge] This article gives a description of the PSDE Accelerometer Ex- periment. The main objectives of this experiment are to measure the in-orbit behaviour of a typical telecommunications satel- lite's structure in order to obtain data for the Silex PSDE optical payload which requires high pointing accuracy. The sec- ondary purpose of PAX is to monitor the different mechanisms on board Olympus at intervals throughout their lifetime in order to detect trends in their performance. Extensions of the ESTEC Test Centre [A. Classen] The article decribes the new Test Preparation Area, the Large European Acoustic Facility and a Compact Payload Test Range at ESTEC. Together with the existing Large Space Simulator, the electrodynamic Multi-Shaker System and the large test preparation area they provide Europe with an integrated test centre. Computer Networking via High-Speed Satellite Links [C. Garrido, P. Viau, J. Stjernevi] A description is given of the connection of two Local Area Net- works via a point-to-point link through the 20/30 GHz payload of ESA's Olympus communications satellite, using of-the-shelf hard- and software. o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o | Harm Munk | | o Knowledge Base Systems Group | Of course I only o | Philips Centre for Software Technology | can speak for my- | o P.O.

In Ottewell's 1991 Astronomical Calendar there are fine drawings of the path of the umbra across the globe on 11 July. Ottewell remarks that he scaled the drawings to show the globe as it would be seen from geostationary orbit -- which got me to thinking... There are these fine weather satellites looking down on the west coast and pacific. Would it be possible for one of them to take pictures of the umbra, a 300 kilometer oval of shadow, as it sweeps over Baja or Mexico on that day? Just one picture would be keen, while a "movie" sequence could be really splendid -- if the shadow will have visible contrast, if the weathersat has a fast enough exposure time and wide enough field of view, etc etc. Does anyone know? How would one get this idea to the people who can follow it up effectively?

Graham) Subject: Adam Brody, where are you? The above headline describes my problem. I have been trying to send e-mail to Mr. Brody, looking for information about docking, and a local sysop (named Shirin Tabibzadeh) sent the mail back, indicating Mr. Brody as an unknown user. So, just in case Mr. Brody is looking in, here are my questions: In article <7749@eos.arc.nasa.gov>, you write... >I have been researching the manual control aspects of docking operations >(control modes, braking gates...) for about six years including 2 masters >theses. I know this info is not quite what you wanted but I thought >I would offer. It's plenty close enough. Could I prevail upon you to e-mail some titles? In article <7743@eos.arc.nasa.gov>, you write... [Soviet docking history deleted...] After a brief review of the above history, I have come up with a couple questions, which maybe you can help out with if you have time: o can you give me a more detailed reference for each of the following: - Sedej & Clarke, 1988 - Clark, 1988 - Hillyer, 1986 o what can be said about laser range-finders? Is there an appropriate reference? I have looked into definitions of terms for optical guidance (some form of position measure, based on star position, as opposed to inertial navigation) and range-finders (horizontal distance, needing some reflective surface), and, using your article as a starting point, I will try to use our own library to locate more information...I am just interested in picking up whatever information you might have handy. Thanks much. RG ------------------------------ End of SPACE Digest V13 #021 *******************
