Hubble telescope placed in a multilayer plastic bag [!] to provide extra protection from airborne contamination. The bag will stay on until the telescope is loaded into the orbiter. As an extra precaution, to minimize airborne particles, burning of swamp areas at KSC has been halted until after the HST launch. State of South Australia studies reviving the abandoned Woomera rocket range as a commercial facility for aerospace hardware testing. [marginally space related] SR-71 operations terminated due to high cost and continued USAF confusion about reconnaissance plans. Some Congressmen say government support of private space activity remains lukewarm at best, with DoT taking its time about launch regulations and government agencies not exactly bending over backward to buy private launches rather than running their own. Interest in small military satellites continues to grow. USAF Space Command produces tentative set of requirements for a tactical satellite system. Congress boosts DARPA funding for rapid-replenishment ideas, strongly approves of Taurus, and orders Secretary of Defense to remove the no-technology-demos-in-space restriction from the Lightsat program. One major challenge is getting customer support from lower-level military commanders; smallsat demos during military exercises are being talked about, with emphasis on giving field commanders control of the birds. Ariane manifest in chaos again as launch V35 (Japan's Superbird B and BS-2X) slips due to payload problems. Spacecraft checks after the San Francisco earthquake raised some doubts about reliability of Superbird's main amplifier (the problem is not quake-related). NHK, which owns BS-2X, is unhappy: BS-2X is meant to replace a comsat that is having trouble in orbit, and they want it up ASAP. [The latest word is that the next launch will be Spot 2 and its amateur-radio piggyback birds, with the rest of the 1990 manifest blank pending rescheduling.] ESA puts Phase B work on the Soho solar/heliospheric satellite on hold until the US approves the ESA/US memorandum of understanding for the project. ESA approved it 11 months ago; since then it's been sitting in the US State Dept, held up by quibbling over minor wording problems. Roger Bonnet, ESA science director, says "I can't understand this whole situation -- it is so irrational it surpasses my comprehension." Phase B was meant to start Oct 1. The MOU covers Soho and Cluster, both parts of the International Solar-Terrestrial Science Program. Phase B work on Cluster is underway despite the MOU problems, basically because the US role in Cluster is much less crucial and ESA can do Cluster alone if necessary. Soho depends on a US launch and a US operations package, and going it alone would add $150M to ESA's budget for Soho. Soho is already several months behind schedule and several million dollars over budget because of NASA hardware-delivery delays. Bonnet says ESA will not sign the MOU for Cassini/Huygens -- ESA is to supply the Titan probe for the Saturn mission -- until the Soho/Cluster mess is resolved. Time is getting tight; major work on Cassini/Huygens is to start Jan 1991 and the ESA approval process does take several months. "I cannot go to our [management] seeking approval for another MOU while everyone knows that we are still awaiting US approval of the earlier agreement..." Hardware/software integration problems with the microwave instrument on ESA's ERS-1 remote sensing satellite delay its launch several months. It was originally to go up Oct 1990, and slip to 1991 is now likely. Dassault shows a design study for a two-stage spaceplane, with a large hypersonic aircraft carrying an expendable second stage topped with a Hermes derivative. First Pegasus captive-carry test flown Nov 9. ESA [Roger Bonnet again] says Hipparcos may achieve nearly all of its original mission. No degradation due to the Van Allen belts has yet been seen, and this augurs well for a mission lasting the original 2.5 years. ESA is negotiating with NASA for use of ground-station facilities at Goldstone, which would raise tracking coverage to about 90% in conjunction with the main Hipparcos station at Odenwald and the hastily-added stations at Perth and Kourou. The big concern now is the eclipse period in spring; the eclipses will last quite a bit longer than the ones in Clarke orbit, where Hipparcos was meant to go. However, the engineers think things should be all right, and there may be just enough power to continue operations through the eclipse period instead of having to shut down for a couple of weeks. After the eclipse period, Hipparcos's health will be re-assessed and ESA will decide whether it is necessary to shut it down and start building Hipparcos 2 instead. Pictures of Soviet spaceplane models and prototypes, including a subscale Buran flown to Mach 16 for design verification. [Latest entry in the Why-Wasn't-This-In-Aviation-Week contest, from the 15 Nov issue of Flight International:] NASA releases details of the plans for scaling down user support aboard the space station. NASA will provide less equipment, partly on grounds that NASA historically has not been good at guessing what experimenters will need (example: the complex freezer microscope on Skylab, never used). The US lab module no longer has windows, and the "sewer" -- a venting system for waste gases -- is gone too. There will be no animals in cages (partly as a result of the bad experiences on Spacelab 3). There will be one airlock rather than two, and various gadgets like the acceleration-mapping system are gone. "Main facilities will have to be paid for by the user." User power will be 37.5kW, supplied as DC at 160V and 120V. The active cooling system is gone in favor of passive cooling. The [stupid] idea of private funding for the Flight Telerobotic Servicer has been dropped, although NASA money may come from outside the station budget. [For those not aware of it, the FTS is basically Congress's pork-barrel project for the US robotics industry. It doesn't seem to do anything that the Canadian arm system won't.] There will be no exterior-mounted instrument-pointing systems provided, so users who want them will have to bring their own. The station spacesuit is gone, and shuttle suits will be used for EVA. [From 3 Nov issue of Science] First results are in from the protein-crystal-growth experiment on STS-26. Three of the eleven materials produced crystals "far superior" to any seen before. Most of the remainder produced "showers of little tiny crystals", thought to indicate a vibration problem. Improved versions of the experiment are under development; the payoff of space experiments is much higher than comparable ones on Earth. "We can work for a long time on the ground here to get an improvement much less dramatic..." [And some oddments from the 21 Oct Flight] McDonnell Douglas plans to build another Delta pad at the Cape, including facilities for liquid-hydrogen loading for a planned new upper stage using an RL10 [Centaur] engine. General Dynamics studies another Atlas variant, with solid strap-ons but without a Centaur upper stage. NASA finally releases RFP for studies on the station lifeboat, stressing use of "existing technologies" for a simple and reliable vehicle. Full scale development would start in 1992. -- 1972: Saturn V #15 flight-ready| Henry Spencer at U of Toronto Zoology 1989: birds nesting in engines | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 19 Dec 89 15:28:52 GMT From: frooz!cfa.HARVARD.EDU@husc6.harvard.edu (Bill Wyatt) Subject: Re: Big Bang: Did it happen?

[...] Well, the BB in general is separate from inflation theory. And no, inflation theory certainly does not do `a fine job': it is a pretty theory completely at odds with observations. Most theorists really *want* the Universe to be closed (i.e. Omega >= 1.0), so much so that they call these the `standard' theories. People ignore the fact that the standard theories currently require exotic (i.e. unknown) physics. The inflation theory predicts Omega is exactly 1.0000... , but every piece of observational evidence says Omega is between 0.1 and 0.3, so the Universe is open. There are lots of truly creative ways of reconciling the discrepancies; shadow matter, tailored particles, etc., etc. None of them has any observational basis; their sole reason for being is to close the Universe.

The collection of many engineers, in many companies, working on micro- minaturization of ICs for space applications, funded by NASA for Apollo, freed this pool of talent from the constraints of "business necessities". My suspicion is that the pace of the IC industry growth benefited enormously from this freedom, and that if IR&D had to fund the 4Mb DRAM antecedents and associated technology (rather than NASA & USGov.), we would not see these at this time. Apollo created a large body of of engineers, (and the public), aware of what microminiturized technology could do. "It put a man on the Moon" etc. The technical success of Apollo and micro-tech was demonstrated for all of the Corporate Boards of the world, and many of these decided to give more money to their IR&D people. After all, you might be able to make some interesting products from these smaller ICs, especially since NASA paid many basic research costs. In effect, Semitech, Semiconductor Research Corporation (SRC), MITI, and DARPAs continued semiconductor research support, all mimic what NASA did at this time. It`s unlikely that IR&D would have carried us to this point, this fast, by itself if not for the politics of the space program, and its high visibility. Put another way, ICs were proved and sold by Apollo, in the biggest way possible. Great advertising!

There is very little activity at Space Shuttle Launch Pad 39A at Kennedy Space Center. The orbiter remains powered down. Heaters remain on in the orbiter's OMS pods, the solid rocket booster's aft skirts and the forward reaction control system. Some maintenance work is underway on the launch processing system in the launch control center. United Press International reports that astronaut Mission Specialist David Low will carry a pair of very old tan silk socks into space on the next space shuttle mission. The heirloom hosiery was worn by Cornell University founder Ezra Cornell on his wedding day in 1831. Johnson Space Center spokesman Jeff Carr says the pair of socks "doesn't sound unusual" to NASA. Astronauts usually carry small, lightweight mementoes from their alma maters. The socks weigh less than an ounce. Aerospace Daily says a revised space shuttle manifest will not come out before mid-January. Mission managers will wait until after the STS-32 mission to assess what effect the launch delay will have on the other nine missions scheduled for 1990. The Australian government has approved plans for a commercial spaceport. Space Daily says the facility on the Cape York peninsula will exclusively use the Soviet Union's Zenit boosters for commercial satellite launches. The initial launches from the proposed $450 million spaceport are scheduled for 1995. The publication says the decision to use the Soviet built rockets was based on much lower costs and proven reliability. The proposed Cape York site is located 14 degrees below the equator. An environmental impact study is scheduled to begin in March. A search for customers and private funding is also underway. White House Science Adviser D. Allan Bromley says the pre-college educational system in the United States is a "disgrace and a scandal." The Yale University scientist-educator told the Washington Post that many U.S. university graduate departments for science and engineering are entirely populated by foreign students. Bromley says the White House is "working agressively" on a program to set national education goals for science studies. * * * * ----------------------------------------------------------------- Here's the broadcast schedule for public affairs events on NASA Select TV.
