I'll ignore the capital equipment. But if I follow your argument, all flights not related to research should be provided by a private firm? What about training? What about flights in and out of Edwards? I'd bet that NASA owns a few flight articles that are used for operations and not for research. Do we apply your argument against using the shuttle for operations to those areas as well? The Shuttle supporters (for the most part) continue to question whether or not the DC-X/Y/1 supporters are suggesting that we cancel Shuttle before DC-X/Y/1 is operational. I've requested that the DC-? proponents put up a straw man proposal of exactly when the Shuttle would be phased out. This request was ignored. I'll reiterate the request: Exactly when do you propose discontinuing Shuttle operations? Exactly when do you believe DC-1 will fly? Exactly what will happen if DC-1, for whatever reason, is years late, or turns out to be as problematical or more problematical as the Shuttle? Its my impression that the Shuttle supporters are against shelving the United States' manned space program merely to save a few billion a year. They aren't against saving money, they aren't against DC-1, they just believe that there are unacceptable risks associated with depending on a system that isn't flight ready, let alone exist. I will not support a position that requires the cancellation of the US's manned space program years in advance of a replacement from the private sector. But if you continue to believe that the supporters of the Shuttle are, by definition, anti DC-X/Y/1, then continuing any discussion is pointless.

TELEPHONE (818) 354-5011 MARS OBSERVER MISSION STATUS January 5, 1993 The Mars Observer spacecraft is being prepared for the outer cruise flight sequence. Adjustments to point the high-gain antenna directly at the sun are continuing through Jan. 6, 1993, at which time the antenna will be powered on to begin receiving and sending engineering and science data. The spacecraft team reports that all spacecraft subsystems and instruments are performing well. The camera "bakeout" to prepare the instrument for operation will continue through Jan. 14, followed by a focusing test on Jan. 18. Today the spacecraft is about 43 million kilometers (27 million miles) from Earth, traveling at a speed of about 36,000 kilometers per hour (23,000 miles per hour) relative to Earth. The spacecraft is traveling at a heliocentric velocity of about 97,000 kilometers (61,000 miles per hour). One-way light time is approximately 128 seconds. ##### ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | Choose a job you love, and /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | you'll never have to work |_____|/ |_|/ |_____|/ | a day in your life. ------------------------------ Date: 5 Jan 93 19:21:00 GMT From: soc1070@CRABAPPLE.SRV.CS.CMU.EDU Subject: Moon Dust For Sale Newsgroups: sci.space,sci.astro,alt.sci.planetary In article <1993Jan5.162900.14264@aio.jsc.nasa.gov>, kjenks@gothamcity.jsc.nasa.gov writes... >In article <1iaeeuINN7kq@darkstar.UCSC.EDU> banshee@cats.ucsc.edu (Wailer at the Gates of Dawn) writes: >NASA is part of the Executive Branch of the U.S. Government.

The difference is that there is no private competition for these facilities and in the case of the private jets, they save money. Shuttle doesn't save a dime and does harm the US commercial space industry by dumping launch services. >The Shuttle supporters (for the most part) continue to question whether or >not the DC-X/Y/1 supporters are suggesting that we cancel Shuttle before >DC-X/Y/1 is operational. As far as *I* am concerned, the two have absolutely nothing to do with each other. It is *MY* belief that Shuttle has failed and must be replaced with cheaper alternatives. I believe that Shuttle has failed on its own merrits and not relative to any hypothetical vehicle. Long time readers of sci.space will know that I held this position LONG before there was a DC program and will continue to hold it regardless of what happens to DC. Now I have no idea how other people feel, I only speak for myself so your use of the plural may not be accurate. >I've requested that the DC-? proponents put up a >straw man proposal of exactly when the Shuttle would be phased out. This >request was ignored. I have already answered that from *MY* point of view. Again, I cannot speak for others so the use of the plural is incorrect above. I will restate it: At this time, DC is too risky a venture to gamble the entire US space program. What is needed is an intermediate system which does those things we actually do with Shuttle but at lower cost. At the same time, the alternative must be commercially funded since Shuttle is consuming too much money to build anything. Finally, it would be nice if didn't destroy all the elements of this intermediate system. What we need is: 1. facility with shuttle like amounts of space, power, and life support where experiments can be run. 2. Human and automated access to that facility 3. A mechanism to return experiments. To get all this, we should: 1. Several companies have offered to build facilities like this. The Industrial Space Facility is perhaps the most famous. All they require is for government to agree to be an anchor tennent if they can build it. Step one would be for NASA to sign just such an agreement. 2. For access, we use a Syouz mated to an Atlas or Titan. This is a cost effective alternative which will work for a long time or can be dropped shold DC pan out. 3. The Russians also make a wide variety of return capsules which we can use for this. In a pinch, we build our own return capsule. This is a very simple vehicle like an Appollo or Gemini capsule. We in the past, and the Russians today make these without much trouble. Surely we aren't so far behind the Russians (and our own capabilites only recently) that we can't do this. Like 1 and 2 above, this is something the government busy, not developes. If government will agree to use these facilities, the private sector can build them. Total development costs should be under one years Shuttle operations costs and operations would be at most 40% of Shuttle costs. If DC works, we save a billion or so more. If it fails, we simply settle for the $3 billion or so this saves. BTW, note that under this scheme we get access for 365 days instead of the 40 or so we get today. All it would take to get it is for NASA to agree to use it when it became available. >Its my impression that the Shuttle supporters are against shelving the >United States' manned space program merely to save a few billion a year. That is why we haven't gotten anywhere in space for the last 15 years. Tell me something, shuttle supporters, how much would a Shuttle system be worth to you? Suppose a flight costs $10 billion; would you still support it? How about $100 billion? >But if you continue to believe that the supporters of the Shuttle are, by >definition, anti DC-X/Y/1, then continuing any discussion is pointless. Again, as far as I am concerned, these are two completely separate issues. Between Shuttle and DC there are four possible pro/con positions. I, myself, know people holding all four positions.

This is most probably an exaggerated account of Krikalev's mission 5/91 - 3/92. He was originally to return in 10/91 but this was delayed until the next crew exchange on 3/92 due to the Kazak cosmonaut being added to the 10/91 mission. Krikalev was never in any unusual danger because of this, and he was never alone on Mir. I met him last August so he made it back okay. This story was grossly exaggerated by the western press. Krikaley got extra bonus pay for staying also. Soyuz are always left attached to Mir for emergency return of the crew. Information is radioed to Mir periodicially about emergency reentry and landing sites available around the world. If cosmonauts really needed to return to Earth from a space station, they need only to fly the Soyuz back like the Soyuz T-14 when Vasyutin got sick. >I recall reading that at some point earlyish in the Russian space >programme that there was a retro mis-fire on one of their missions. >This lead to the unfortunate situation of the space craft in question >flying off directly into the sun.

This last one sounds like stories about the Soyuz 1 accident. There were rumors for years about someone listening to Komarov as he decended to Earth and the parachutes failed (this part is true, he was the first spaceflight fatality). Its very unlikely his wife would even have been in contact during his short and troubled mission. Also, for any manned spacecraft yet constructed I'm sure it would be impossible to reach the Sun by a failed retro burn, there just isn't enough performance. It's probably impossible to even intentionally fly to the Sun.

Because you continually fail to recognize the lobbying power of Rockwell International, Lockheed, and Thiokel to keep the Shuttle going. You have no imagination of the outcry which would occur to use Soyuz as a primary piece of hardware in an American program. "Look, we really don't give a damn about our own technologies anymore, so we will become depending on the Russians." If you don't believe me, wait until the fight occurs to kill Freedom dead and rent space on Mir, which is a MUCH more likely scenario than killing a symbol of technological pride and replacing it with a tin can. Symbolism. So where can I FTP a picture of a Soyuz and Mir on the net? Posters of Shuttle decorate the walls of Aerospace departments and children's bedrooms across the country. Not many of Soyuz. Why does Henry get so huffy about CanadARM on Shuttle flights? :-) Symbolism.

No, Allen, if you're going to use cost as a driver to save money, the penny pinchers on the Hill are just as likely to take it to extreme and send our boys out to the steppes.

After all, it will save sooo much more money than trying to integrate a Soyuz on Titan or Atlas.

Launch of a SLBM would automatically cause panic buttons to be hit all over the place and would result in a MUCH higher alert status of strategic nuclear forces. Which thereby puts the Other Side into a higher alert status and pretty soon everyone is sweating more profusely than either first imagined... Secondly, U.S. forces are EMP hardened, so all you've done is: A) Raised the level of tension B) Invited attack on any space assets you've got C) Tossed public opinion and the world community off your side; NOT a good thing. Tomorrow's battlegrounds are as much as hearts and minds as they are of men and machines.
