Atlantis had been moved from the Vehicle Assembly Building to launch pad 39-B on Friday. Following the move, auxiliary power unit #3 on Atlantis was successfully hot- fired. Work occurring at the pad today includes the helium signature leak check of Atlantis' main propulsion system. This is the third day of very heavy rain and high winds in the Kennedy Space Center area. As a result, about 10 gallons of rain managed to intrude into the Pad B orbiter aft area. That water is being cleared out now and is not considered a problem. Also because of the rain, the STS-37 flight crew was diverted from the Shuttle Landing Facility to Patrick Air Force Base yesterday when they flew in from Houston. The crew is in Florida for the STS-37 terminal countdown demonstration test, which begins tomorrow and concludes on Wednesday at 11:00 am. Space Flight and Kennedy Center management have decided to install on Discovery the flapper valve door closure assembly from Columbia. Columbia's two assemblies are presently at Rockwell International Space Division's Downey, Calif., plant for refurbishment. They are expected back at the Cape this week for installation into Discovery. KSC technicians expec able to roll Discovery from the Orbiter Processing Facility to the VAB by March 28. * * * * * * * * * * * * * * * * Kennedy Center and NASA Life Sciences Division management will hold a press showing of the Spacelab Life Sciences-1 Spacelab module tomorrow, March 19, at 1:00 pm EST in the Operations and Checkout Building. Members of the STS-40 SLS-1 payload processing team will be on hand to answer questions about the module and how it is processed. The main objective of the STS-40 SLS-1 mission, now scheduled for launch in May, is to study the dynamics of certain physiological changes which occur during space flight and to investigate the consequences of the body's adaptation to microgravity. * * * * * * * * * * * * * * * * Jet Propulsion Laboratory flight controllers report that Ulysses is performing well and continues with routine science data collection. Flight controllers say a low level of wobble was detected during maneuvers carried out to improve the spacecraft's high-gain antenna pointing. These wobbles are not expected to recur in this mission phase, though. Ulysses is presently about 175 million miles from Earth and travelling at a heliocentric velocity of about 56,800 miles per hour. The spacecraft has another 274 million miles to go before reaching Jupiter in February 1992. * * * * * * * * * * * * * * * * Marshall Space Flight Center engineers tested an advanced Space Shuttle Main Engine for 170 seconds this past Friday. Marshall technical assistant Dan Dumbacher said they had a "full-duration test and an initial look at the computer data indicates it was a successful test." It was the 21st test firing at the Technology Test Bed facility at Marshall's West Test Area since testing began in September 1988. * * * * * * * * * * * * * * * * NASA has terminated the operation of the Dynamics Explorer-1 (DE-1) spacecraft. The spacecraft, which acquired the first global images of the aurora, was launched on August 3, 1981. It was designed to last three years and to study the coupling of energy, electric currents and mass between the Earth's upper atmosphere, ionosphere and magnetosphere. Project scientist Dr. Robert Hoffman said the quality and quantity of data returned from DE-1, and a companion spacecraft, far exceeded their expectations. The spacecraft was terminated because it had refused to accept commands since Nov. 17 and because of operation cost considerations and the diminishing value of the data returned.

Publisher's address is - South Pacific Science Press 8 Maddox St Alexandria, NSW 2015 AUSTRALIA I found it in a newsagents; I don't have anything to do with it, but thought you'd like to know. As far as Cape York goes, there are now "believed to be up to twelve expressions of interest with the Australian Space Office". Companies and consortiums can compete for the running of the project. "... all this is subject to the satisfactory completion of an environmental impact report. It would be surprising if this process did not itself result in changes to the proposal. A finding that Temple Bay is not the best launch site in Australia should surprise no one. In fact, it seems the whole project is up for redefinition. Who will build and run it, where and when, is now uncertain."

Both design and operation were usually controlled outright by industry, though in some cases (eg roads) these were contracted out. All of them served existing markets in a well-defined way (eg speeding up delivery of mail), rather than developing new products. In this way, infrastructure in search of customers was largely avoided. Current space infrastructure is being designed from scratch by government agencies, with no economically scaled antecedents, and with business analysis (if any) thrown in as an afterthought. In large part, that why it is failing. -- Nick Szabo szabo@sequent.com "What are the _facts_, and to how many decimal places?" -- RAH -- : Nick Szabo - via FidoNet node 1:102/851 (818)352-2993 : ARPA/INTERNET: Nick.Szabo@p0.f851.n102.z1.fidonet.org : UUCP: ...!{elroy!bohica,elroy!wciu,cit-vax!wciu}!mcws!851.0!Nick.Szabo : Compu$erve: >internet:Nick.Szabo@p0.f851.n102.z1.fidonet.org ------------------------------ Date: 11 Mar 91 16:30:00 GMT From: agate!linus!philabs!ttidca!quad1!bohica!mcws!p0.f851.n102.z1.fidonet.org!CARY.OLER@ucbvax.Berkeley.EDU (CARY OLER) Subject: SOLAR TERRESTRIAL BULLETIN - 11 MARCH (INFO UPDATE) From: oler@HG.ULeth.CA (CARY OLER) Path: wciu!elroy.jpl.nasa.gov!swrinde!zaphod.mps.ohio-state.edu!magnus.ircc.ohio-state.edu!tut.cis.ohio-state.edu!ucbvax!HG.ULeth.CA!oler Newsgroups: sci.space Subject: SOLAR TERRESTRIAL BULLETIN - 11 MARCH (INFO UPDATE) Message-ID: <910311013041.208022b2@HG.ULeth.CA> Date: 11 Mar 91 08:30:41 GMT /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ SOLAR TERRESTRIAL BULLETIN 11 March, 1991 Updated Solar Activity Information Potential Geomagnetic Storm Warning Cancellation /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ UPDATED SOLAR ACTIVITY INFORMATION The Potential Geomagnetic Storm Warning for middle latitude regions has ended as of 11 March. Geomagnetic activity has been at quiet to unsettled levels now since approximately 07:00 UT on 10 March. Conditions are expected to remain generally quiet to unsettled over middle latitudes. High latitudes could experience brief periods of minor storming, although it appears that even high latitudes will remain generally unsettled to active with little (if any) magnetic storming. The activity which occurred over the past 48 hours has been attributed to the major flaring which occurred on 07 March. A well placed coronal hole is also believed responsible for contributing somewhat to the activity. Solar flare activity over the past 24 hours has been relatively dormant. No M-class flares have been noted today. The most powerful flare was a class C7.4/SF from Region 6538. Spot activity is quite a different story. Region 6538 has continued to be impressively active with regards to spot activity. This region has bloomed with spot activity. The inner area of this region is fairly dense with spots. Region 6538, now located at S23E20, has continued to increase in size and complexity. A magnetic delta configuration has now appeared together with the beta-gamma configuration. Spot count has increased to 109 in this region today. It covers a large 27 degree angular extent. Region 6537 (S08E01) has also increased in size and magnetic complexity over the past 24 hours. This region now encompasses 28 spots and has been reclassified as a magnetic beta-gamma configuration. This region was responsible for spawning an X-class flare earlier this week. Region 6538 is now well place for providing high terrestrial impacts should a significant major flare erupt. Within the next 48 to 72 hours, this region will also be capable of producing potentially strong proton and PCA activity if a major proton flare occurs. It is somewhat unusual that this region is as inactive as it has been over the past 24 hours. This may be a sign of stabilization, but considering the amount of spot activity occurring in the region and the continuing magnetic complexity, significant major flaring is still very possible from this region. Isolated major M and/or X-class flares continue to be a threat. HF propagation conditions have returned to normal over most low and middle latitudes. Significant high-latitude improvements have also occurred over the past 24 hours. Increased signal stability and decreased absorption are expected over the next several days. A strong possibility exists for SID-induced SWF's. However, any SWF's should be relatively short but could be of moderate to high intensity (particularly if a major flare occurs). VHF propagation conditions could be quite good on the lower bands. MUF's have increased recently and may now support possibly widespread openings on 6 meters, particularly over the shorter distances (under approx. 3000 km [1900 miles]). Frequencies near 50 MHz are more likely to support potential DX. The most favorable times for potential DX exist when the sun is at its highest elevation in the sky at the midpoint of the signal path. For north-south paths, this optimal time occurs near local noon. Auroral activity has diminished significantly over the past 24 hours and is now not visible over the middle latitudes. No further activity is expected over the next 24 hours. Whether activity increases after 48 to 72 hours is heavily dependent on whether any major flaring occurs. ** End of Bulletin ** -- : CARY OLER - via FidoNet node 1:102/851 (818)352-2993 : ARPA/INTERNET: CARY.OLER@p0.f851.n102.z1.fidonet.org : UUCP: ...!{elroy!bohica,elroy!wciu,cit-vax!wciu}!mcws!851.0!CARY.OLER : Compu$erve: >internet:CARY.OLER@p0.f851.n102.z1.fidonet.org ------------------------------ Date: 18 Mar 91 19:54:41 GMT From: sdd.hp.com!caen!uflorida!cs.fau.edu!news@ucsd.edu, Ertem@andrew.cmu.edu Subject: Looking for satellite imagery.
