We understand that it operates in such a manner that all that matters is the "Holy Bible". That is, the paperwork. Whether the **hardware** works does not matter to NASA or the contractors. We here on the usenet use a different system: we examine whether the hardware works or not. We don't care whether the paperwork was doen correctly .. for example, the paperwork for the (last) challanger launch was in perfect shape: it was OK to launch in cold weather. This was official, agreed to by management. That it was not the opinion of the people who knew did not matter. Except that people died. The paperwork said that the Hubble Space Telescope mirror was the most perfect ever made. Despite the fact that the manufacturer has tests that clearly said it was defective. Despite the fact that the defective test they used to say it was perfect was based on a kludged device that clearly was not assembled according to specs. Despite the fact that the mirror was indeed wrong. The point is that NASA often simply defines their political position to be correct, despite the fact that it is wrong. Because of this undeniable record (just **try** to deny it and see how far you get .. we have the death certificates and the measured performance of the HST to prove you wrong) we **must** assume that anything NASA says is likely a political lie and the "unsupported rumors" should be examined very carefully, to see if we can predict an upcoming fiasco in advance.

News flash: the new NASA brochure describing the Clementine mission should be off the presses next week. Sorry, don't have title or serial number. Clementine, which is bending metal *now* and aims for a January 1994 launch, is a 140-kg spacecraft which will orbit the Moon for two months, then depart to fly by the asteroid 1620 Geographos in August 1994. Some contributors to sci.space are involved in this project. The major purpose of Clementine is to test SDI sensors in space. As long as they need to fly a couple of UV-visible and IR cameras, and a laser altimeter/LIDAR, they decided to do some lunar and asteroid science with them. They would like to map the Moon in twelve bands and get as much altimetry as they can. This is jointly managed by the Strategic Defense Initiative Organization and NASA. Spacecraft is being built by the Naval Research Laboratory and sensors are from Livermore. I detect no JPL involvement (sorry, Ron). -- O~~* /_) ' / / /_/ ' , , ' ,_ _ \|/ - ~ -~~~~~~~~~~~/_) / / / / / / (_) (_) / / / _\~~~~~~~~~~~zap! / \ (_) (_) / | \ | | Bill Higgins Fermi National Accelerator Laboratory \ / Bitnet: HIGGINS@FNAL.BITNET - - Internet: HIGGINS@FNAL.FNAL.GOV ~ SPAN/Hepnet: 43011::HIGGINS ------------------------------ Date: 11 Mar 93 10:33:12 -0600 From: Bill Higgins-- Beam Jockey Subject: Clementine resolution (was Re: Lunar Ice Transport) Newsgroups: sci.space In article <1993Mar10.221401.9227@sol.UVic.CA>, rborden@uglz.UVic.CA (Ross Borden) writes: > In article henry@zoo.toronto.edu (Henry Spencer) writes: >>The lunar map situation is, roughly speaking, incredibly poor.

Well, that *is* what we were talking about, Tom, which is why several of us are questioning this idea of replacing the whole thruster on SSF instead of using refueling technology that would allow us to either boost more fuel per load or else have room for other stuff in addition to the fuel. That 12k lbs or so dry weight on lifting thruster units would hold a lot of 'second payload'.

Anyway, he has been a prof here at MIT for a few years coming here from Raytheon, I believe. He had a big part in the increased reliability of the Patriot missle (reliability, as in it fires when you want, not as in it hits when you want). He tought a spacecraft design course which a few of my friends took, and said was decent. I saw him give a number of talks, and he sounded like a fellow with a great deal of common sense.

I couldn't say for certain, but I would certainly expect to find most small bodies orbiting appreciably larger bodies to be tidally locked (within a certain limit for 'small' -- if it is too small to have real tidal forces across its diameter, I would suspect that tidal locking wouldn't take place). We used to think that Mercury was tidally locked to the Sun, but it turns out that it is not. It is also worth noting that the tidal forces of the smaller body upon the larger also slow the rate of revolution of the larger body. For example, the Earth used to have a faster rotation than it does now. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Ames Dryden ------------------------------------------------------------------------------ Fred.McCall@dseg.ti.com - I don't speak for others and they don't speak for me. ------------------------------ Date: Thu, 11 Mar 1993 13:59:18 GMT From: Dave Stephenson Subject: NASA and gold Newsgroups: sci.space >In article <1993Mar10.164358.294@nhqvax.hq.nasa.gov> jthompso@nhqvax.hq.nasa.gov writes: >>Does anyone know why NASA uses gold in the satellites when it has the >>third lowest resistivity next to silver and copper? ... >Uses gold in the satellites for *what*?

As you should know, payloads spend long periods of time on the ground waiting for launch, therefore resistance to corrosion is important. You may not know that even in orbit there is energetic monoatomic oxygen present that can pose corrosion problems. Gold also has excellent mechanical and thermal properties that make it well suited to the extreme environments a space payload will face during construction, launch, and deployment.

Any help appreciated. It does not corrode, and is extremely malleable and ductile, and is therefore more easily manipulated and less fragile in thin films or fine wires. Also, at high frequencies almost all conduction takes place along the surface of the conductor, so the freedom from corrosion actually may make gold a better conductor at high frequencies (corrosion tends to make the surface topology more "fractal"). -- -------------------------------------------------------------------------- All opinions are MINE MINE MINE, and not necessarily anyone else's. det@phlan.sw.stratus.com | "Laddie, you'll be needin' something to wash | that doon with." ------------------------------ Date: Thu, 11 Mar 1993 15:45:32 GMT From: fred j mccall 575-3539 Subject: NASA and gold Newsgroups: sci.space In <1993Mar10.164358.294@nhqvax.hq.nasa.gov> jthompso@nhqvax.hq.nasa.gov writes: >Hello, >Does anyone know why NASA uses gold in the satellites when it has the >third lowest resistivity next to silver and copper?

You can find biological rockets if you look hard, actually, although the squid isn't one. (The bombardier beetle uses a hydrogen-peroxide rocket engine as a defensive weapon, for example.)

I make an exception for Robert McElwaine and a very few others, as they have clearly shown the presence of hard cranial vacuum. If someone feels a need to post anonymously, I have no real problem with that per se. I may take that fact into account when reading some types of subject matter, but I do not make an a priori judgement based on it. Some people will automatically discount an anon posting. Let them. Others of us don't care who wrote it (usually), as long as it is intelligently presented, or witty, or even amusingly unusual. Why is this such a holy cause?
