Re: asteroid almost hits earth ---------------------------------------------------------------------- Date: 19 May 89 02:49:15 GMT From: cwjcc!mailrus!jarvis.csri.toronto.edu!utgpu!utzoo!henry@tut.cis.ohio-state.edu (Henry Spencer) Subject: space news from April 17 AW&ST NASA seeks exemptions from the Freedom of Information Act, to restrict flow of data to foreign nations. Congress isn't enthusiastic. Production of ammonium perchlorate oxidizer at Pacific Engineering's new plant will be delayed until May due to minor funding delays. Goddard Spaceflight Center requests commercial launch services for three satellites, with options for twelve more. The three are Wind, Geotail, and Polar, part of the International Solar-Terrestrial Physics project. NASA approves expanded studies for a space-station rescue vehicle that would remain docked to the station. NASA may be hoping to use the studies to shorten the "advanced definition" stage, once a new administrator is in charge and can make decisions. Army initiative to educate field commanders about the uses of space capabilities is being hampered by excessive secrecy, says BG Robert L. Stewart (ex-astronaut, dep. cmdr. Army Strategic Defense Command): "The world of space reconnaissance is too closed... This is an area that doesn't need to be guarded that closely any more..." US military commanders express concern about lack of a US Asat system, and about the "less operationally oriented" US launch systems (compared to the Soviet ones). DoD considers severe budget cuts for the Aerospace Plane; it is unlikely that NASA could pick up the slack. SDI reconsidering Brilliant Pebbles cost estimates. SDI laser development, in particular, has been moving very slowly and is eating up a lot of the SDI budget, which dampens enthusiasm for costly new projects. NRC panel tells NASA that the Commercially Developed Space Facility is too expensive and not useful enough, and that most near-term microgravity work can be done with an extended-duration shuttle orbiter. It does say that the idea should be reconsidered if the space station is delayed more than a year or two. [Do they *really* expect that it *won't* be delayed at least that long???] Panel says that NASA could build the platform for only slightly more than it would cost to lease it. [Oh really?] CDSF would give more power and better microgravity, but neither is critical for near-term experimental work, says the panel. Finally, panel says that there is little chance of substantial commercial activity in microgravity work in the near future. Space Industries and others are not so sure. SI points out that the panel was solid basic-research people, and simply doesn't know what's going on in the commercial world. Max Faget [SI's founder] says stronger private- sector role must be provided if the US civil space program is to succeed: "The government has dominated, providing all the infrastructure to date. Every time [it does] a program, it takes longer than before..." Another industry official [unnamed] is strongly critical of the report, saying that of course the panel found no need for more power or better microgravity: all the experiments they looked at were designed to fly on the shuttle! The shuttle imposes major constraints on designers. "These guys recognized things, covered them up and then drew the most negative conclusions possible.. The conclusions are very conservative. They... reflect the stacking of the committee with fundamental scientists." He says the panel based its conclusions mostly on "expert opinion" from NASA. Others who briefed the panel agree. The Senate will conduct major commercial-space hearings in May, and will presumably reexamine this issue. Payload Systems' planned June 15-Oct 1 payload flight aboard Mir is now in doubt due to the Soviet decision to leave the station unattended for a while. PS says it has not yet been officially told of any delay. Soviet engineers have visited PS recently to start flight-approval procedures for the equipment, which is scheduled to go to the USSR in May. The PS experiment consists of three sealed modules which cannot be examined in detail by the cosmonauts. Each module contains a number of solution wells, with a wall between two compartments broken by an external thumbscrew to start the experiment. The cosmonauts will photograph the inside of each well through a window at the end, so that PS can determine whether broken crystals were intact before reentry. Speaking of Mir... Mir cosmonauts prepare Mir for "two to three months" of unmanned flight to give the USSR time to mount a repair mission to deal with electrical-power problems. Electrical failures have begun to severely limit available power, a worrisome issue because life support is the biggest power user. A Soyuz mission carrying a repair crew will be launched in the next 2-3 months. This is the second time the Soviets have had to do major repair work on a manned space station, the first being Salyut 7. The team that saved Salyut 7 has been put in charge of assembling the Mir repair mission. The Mir cosmonauts have been firing Mir's engines to raise its orbit, to give it a longer unattended lifetime. Management shakeup at IKI [the research institute; note this is an entirely different organization from Glavcosmos, which runs Mir, launchers, and the shuttle] is likely as a result of the Phobos failures. USSR is tentatively considering use of the Phobos ground spare to refly the Phobos mission, possibly in 1992. (This indicates a conservative approach in planning, since there is a Mars window in 1990.) Soviet scientists criticize secrecy and poor planning in Soviet space program, blaming disorganization and internal bickering for the lack of fully-approved planetary missions after Phobos 1/2. Soviets will probably bring their An-225 [their shuttle carrier] to the Paris air show, and may show a shuttle orbiter as well. Arianespace delays first flight of the Ariane 44L, the maximum-lift configuration of Ariane 4. There is concern about high vibration levels seen in the third stage at liftoff in the initial Ariane 4 flights. Arianespace says the delay will be "a few weeks"; the first Ariane 44L had been scheduled for April 28. Letter from David P. Gump: "...Twenty-eight years after the Wright Brothers, the general public could buy passenger tickets on a pan-European airline. Twenty-eight years after Yuri Gagarin, the general public is permitted to clap when five government employees take a short ride costing almost $500 million tax dollars. Only priviate initiative, aided by short-term government incentives, will ever open space to the rest of us..." -- Subversion, n: a superset | Henry Spencer at U of Toronto Zoology of a subset. --J.J.

Last week NASA announced an updated shuttle manifest. In order to make certain that the Shuttle program is capable of launching the probe to the Jovian planet on or about Oct. 12, NASA has scheduled only one shuttle flight between the recent Magellan mission and the upcoming Galileo mission. Originally, the Hubble Space Telescope was scheduled to be launched in between the two planetary missions but has since been pushed to Spring of next year. The manifest looks something like this: STS-28 July 31-DoD mission on Columbia; STS-34 October 12-Galileo on Atlantis; STS-33 mid-November-DoD mission on Discovery; STS-32 Syncom IV deployment/LDEF retrieval on Columbia; STS-36-DoD mission on Atlantis; STS-31-Hubble Space Telescope mission on Discovery; STS-35-ASTRO-Spacelab on Columbia. With the completion of a rigorous six month application process, the NASA Safety, Reliability, Maintainability, and Quality Assurance office has announced eight finalists for the NASA Excellence Award for Quality and Productivity. The eight finalists are: Barrios Technology of Houston; Bendix Field Eng. Corp., Columbia, Md.; Boeing Computer Support Service, Huntsville AL.; Computer Sciences Corp., Houston, Tx.; EG&G FL, Inc. KSC FL.; Grumman Technical Services Div., Titusville FL.; Lockheed Eng. Corp., Downey CA. The winner will be announced at NASA's sixth annual contract conference Oct. 31, 1989. Rear Adm. Richard Truly stated to the Senate Commerce, Science, and Transportation subcommittee that the FY'90 budget is "as tight as a drumhead"; and that any cuts in the $13 billion requested budget would threaten the safety of the space transportation system. In short, either safety concerns would have to be forgone which Truly refused to back off on, or less flights would be planned for the future. Later in a round of debate between Senator Jake Garn and J.R. Thomson, current Director of MSFC and nominated to be NASA's Deputy Adm., Senator Garn stated that developing the ASRM development is not worth the extra cost and that if NASA's budget is cut, the ASRM program should be dropped. J.R. Thomas responded that the development of improved SSMEs and ASRM are key programs in making the Shuttle system safer and that possible catastrophic failures would be caused by the current SSME's and SRMs. The FY'90 request is for $496.6 million for the liquid SSME, and $121.3 million for the ASRM, both will come on line some time in 1994 or 95. Acting Associate Adm. of Space Station Freedom Thomas Moser resigned as of May 15 after working for NASA for 26 years. He stated his resignation has nothing to do with the state of the program, it was just that it seemed like the right time to go. He may have been refering to the ethics legislation which goes into effect this week, which would severely limit the consulting and lobbying work which an ex- employee can legally do in the first year after retirement. President Bush has chosen the name 'Endeavour' for Orbiter Vehicle-106, the Challenger replacement. The name was selected out of 6,100 submittals by both primary and secondary schoolchildren. James Cook the was British explorer who first commanded the ship Endeavour on its maiden Voyage in Aug. 1768. The discoveries that Cook made in navigation and exploration have led, at least in spirit, to the possibilities of space exploration. At KSC.... The Space Shuttle Columbia has been undergoing basic main engine testing through out the week, with continued functional testing of waste containment systems, power units, fresh water systems and communication systems. Additional tile work was scheduled to begin on Sunday in the area by the payload bay doors. An Air Force Titan 34D roared off the pad at 3:47 EDT from Cape Canaveral on May 10, launching a pair of advanced communications satellites to handle U.S. military and diplomatic communications. The exhaust of the booster set off several brush fires that kept the pad closed for three hours after the launch, no major damage was reported. Space Commerce Corp. of TX, who has signed an exclusive agreement with the Soviet Union to market the services of Soviet boosters, is going to make a formal offer to launch Space Station Freedom components for a price. In addition they will also start lobbying US companies to consider launching their payloads atop Soviet Boosters. As far as NASA is officially concerned the answer is a strict no; it wishes them well but would in no way consider such an offer. As far as commercial payloads are concerned there are specific State Depratment policies forbidding such arrangements with the Soviets.

Certainly long enough to place >doubt upon the viability of a single catastrophy such as the one mentioned. What prevents the effects of a "single catastrophy [sic]" from propagating over a period of a thousand years? On a geological scale of time, the events of a thousand years constitute less than a footnote in a billion-page volume. Life on this planet seems to be pretty durable, in spite of its perceived fragility. We, the living, while certainly not immune from geological, meteorological, or cosmological influences, won't go away overnight unless the whole planet is blasted to smithereens in one swell foop! Look: a thousand years (or even five or ten) really is just a one-nighter (what a party!). The earth may have lost a host of magnificent species, but did life disappear? I believe the metorite/asteroid collision theory to be the best put forward to date to explain the demise of the dinosaurs and their ecosystem. Your objection, Keith, is ill-considered.

The pro-space arguments I was interested in were not intended for consumption by readers of this news group, who, you are probably right in suggesting, are pretty much sold on the idea. The reasons for an aggressive space program, unfortunately, are not "transparently obvious" to most US citizens. At least, not obvious enough to make them willing to actively back the program. It seems to me that getting more of the public actively backing the space program, and supplying legislators with compelling reasons for voting funding for the space program (reasons the legislators can use to justify their votes), are important, though unglamourous, ways of promoting a government-backed program. Even if you believe in a privately funded space program, it will be necessary to sell the program to folks who don't initially share your enthusiams. ------------------------------ Date: 17 May 89 08:42:10 GMT From: eugene@eos.arc.nasa.gov (Eugene Miya) Subject: Re: asteroid almost hits earth > Alverz et al extinction theory as plausible. Wait a minute! You make a good point that 1K years is just a small amount of time on a geologic or planetary (or many other) time scales. I don't quibble about that, but I can't agree you can't look at this without so skepticism (like fusion, conductors, etc.) Several years I went on one of the yearly Caltech ski trips, when this theory was fresh on every's brain (probably about 1982/3). Okay we discuss work on ski trips (we all get our turn). Luis and Walter (and all the others) still got lots of respect, but one of the people who came up, Peter Ray, a botanist at Stanford, I won't just say "He shot holes thru the theory," but he did raise interesting unanswered questions from the botanical community. None of the original LBL people addressed this questions. You have to study some of these questions in great depth and say, "Oh yeah?! I didn't think about that simple idea which remains unanswered..." Happens all the time. Theories are scientific fads. Good find some serious skeptics, I won't try to paraphrase Peter's questions. --eugene miya, NASA Ames Research Center, eugene@aurora.arc.nasa.gov ------------------------------ End of SPACE Digest V9 #445 *******************
