This person isn't uneducated, I guess, but they have more money than we all can shake our stick at *g*. Whatever: if you follow ebay auctions closely (and those buying there should certainly do that), you get a feel for how much things cost.

[meteorite-list] Mars Exploration Rover Update - November 8, 2004
http://marsrovers.jpl.nasa.gov/mission/status.html OPPORTUNITY UPDATE: Journey toward 'Burns Cliff' Continues - sol 265-271, November 08, 2004 Opportunity's trek towards Burns Cliff continues. The journey has been much more difficult than anticipated. The rover has experienced drive slippage of up to 100 percent. The plan is to attempt a couple of sols of up-slope, switchback driving and then review options to get to Burns Cliff. The rover team celebrated Opportunity's 300-percent mission success anniversary on sol 270. The rover is showing no signs of slowing down despite its advanced age. Spacecraft health is excellent, and solar power is plentiful. Sol details: On sol 265 Opportunity began its drive away from a boulder called 'Wopmay.' The rover performed 45 minutes of remote observations and then attempted a 21-meter (69-foot) drive away from Wopmay. The drive stopped after 3.5 meters (11.5 feet). Opportunity experienced a drive and mobility goal error due to high current draw in the steering motors. Sols 266, 267, and 268 were planned as a single 3-sol weekend plan. Due to the rover's heading at the end of sol 265, the morning uplink session on sol 266 was occluded by the panoramic camera, raising concern that we might fail to get the 3-sol command load to the spacecraft. To avoid this problem, the team instead chose to implement a high-priority communication window at 11:30 local solar time and to uplink all sequences at that time, activating the sol 266 master sequence by real-time command. This plan worked as designed, and all sequences got onboard. The original plan for sols 266 and 267 was to place the alpha particle X-ray spectrometer on the filter magnet for extended integrations. However, Opportunity's position against a buried rock (informally named Son of Bane) and the churning up of sandy terrain meant that we could not rule out the possibility of an unseen rock in the robotic arm's work volume. As a consequence, the arm deployment was cancelled, and the activities for sols 266-267 were limited to remote-sensing observations. On sol 268, Opportunity drove away from Son of Bane. The rover turned and drove forward a short distance to get out of the hole it had dug for itself. It drove about 4.5 meters (about 15 feet) cross slope, and then began an up-slope drive designed to cover 9 meters (29.5 feet). Only about 0.4 meter (1.3 feet) of this last leg was achieved before the rover again encountered 100 percent slip. Due to the large slippage and unsuccessful drive on sol 269, the day was used to take detailed images of the rover's position and to allow the rover mobility team to plan drive strategies for subsequent sols. Opportunity performed more than two hours of remote observations. The rover began a routine of forfeiting deep sleep for as many sols as the battery state of charge would allow. Solar exposure has been favorable enough to reduce the need for deep sleep. In an effort to reduce the backlog of onboard science telemetry that has not been downlinked, Opportunity will support early morning Mars Odyssey communication sessions as long as the battery state of charge is not impaired. Sol 270 was the first sol dedicated to a potpourri of mobility maneuvers to gain a better understanding of the terrain on which Opportunity is driving. The rover completed the drive with no errors and achieved a positive elevation change of more than a meter (3.3 feet). Driving at a 45-degree angle to the slope appears to be the most productive operation. With enthusiasm running high, the uplink team employed strategies of the drive from sol 270 to plan sols 271's drive. Opportunity was to drive up-slope at an angle heading east, towards Burns Cliff, as part of a longer switchback drive operation. But as has often been the case recently, the drive was not successful. Opportunity moved 0.78 meters in a beeline (about 2.6 feet) but experienced 100 percent slippage for most of the drive and ended up approximately 0.35 meters (1.1 feet) lower. Sol 271 ended on Oct. 28, PDT. The result of this drive calls into question Opportunity's ability to reach Burns Cliff with the current approach. The team is assessing other possibilities. Total odometry after sol 271 is 1664.43 meters (1.03 miles). __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Crater question????
The tectonic structures in the Great Rift Valley are amongst the most studied on the planet. We are better equipped today to distinguish volcanic craters from meteoritic ones- I expect that the geology of this caldera is fairly well understood. It certainly couldn't be older than a few million years given the degree of uplift in the area. A personal observation (and quite non-expert) is that this structure's eccentricity argues against an impact origin.

Re: [meteorite-list] Soyuz Capsule Flown Heat Shield
Hi, I have several of these. The ablation and flow lines are interesting, especially in the plugs, and well worth having for comparative purposes. However, the flow lines are in a resin coating of the plug (which is very light weight), not in metal. Re-entry speeds of artificial satellites are much lower than those of meteorites so we shouldn't expect the massive ablation that the latter experience. I am told that the Chinese simply use wood as a re-entry shield. Would be fun to get ahold of some of this. But how would we know it is authentic?

Yes Sterling, I agree with you. Sonic booms are more often than not produced by man-made causes, no matter how much the aviation authorities deny that there were no aircraft in the area. And thanks for pointing out all the misconceptions in this article. But I think the most glaring omission was that there was not one mention of bolides as a possible cause for sonic booms.

Webb [EMAIL PROTECTED] To: Ron Baalke [EMAIL PROTECTED] Subject: Re: [meteorite-list] Suspected Sonic Boom Heard Over England Hi, All, One of many sonic boom reports. Some things to bear in mind. National air forces always deny immediately that one of their planes are responsible. Notice that in this story that the RAF is investigating, but have already denied it was a military plane. What, then, are they investigating? They do so because pilots are not supposed to pop the sound barrier over the civilians and we all know pilots never do anything they're not supposed to, right? As was said in the story, There are regulations governing supersonic flight... And regulations are never broken! Some years ago, I spent a lot of time investigating a sonic boom in my region that was felt over an eighty mile area, a substantial event that broke some windows over a thirty mile wide area. Really big boom. Could well have been a meteor. After about a week of military denials, it turned out that it had been a test flight of a new plane with an enthusiastic test pilot from the plane's manufacturer. He hadn't reported violating flight regulations, of course, until the story wouldn't go away. As for civilian planes being incapable of causing sonic booms, that too is a myth. They are perfectly capable of doing so, but are not supposed to, an entirely different matter. In times past, all large planes were designed with the possible conversion to military use in mind. Many commercial planes in use today could easily go supersonic, but would the pilot and crew want to badly dent their careers by admitting that it had happened, even accidentally? (It's easier than you think...) An uncle of mine, a private corporate pilot, took delivery of a brand new Boeing 707 back when that plane was the very latest craft (1960). As it was to be a cargo carrier, it had no seating and no creature comforts. It was a bare stripped-down shell, all engines and fuel tanks. After having shaken down the ship flying from Seattle to New York, he refuelled and set out to fly from New York to Saudi Arabia non-stop, a long and tedious trip which he enlivened by travelling at a speed comfortable for the vehicle in this configuration. Almost all of his route was over ocean, except for crossing Italy, but then Italy is rather narrow and he thought it wouldn't really be a problem. He was quite surprised when what seemed to be the entire Italian air defense force was scrambled to intercept him as he passed south of Rome at 1120 mph. A lot of explaining to do. It seems they thought he might be a Russian bomber. A silly notion, as the Russians in 1960 didn't have any plane that large that could fly that fast. Then, there are the cases of the many sightings of a hypersonic experimental craft for more than a decade and whose existence is still thoroughly denied. But it's been seen, often over the North Atlantic, so many times and with such agreement in detail that you can go and buy a plastic model of this airplane that doesn't exist. A vehicle travelling at speeds of up to 5000 mph creates a sonic boom that carries for many hundreds of miles and whose extent and persistence is very hard to predict accurately. If only every sonic boom was a meteor about to deposit a fresh fall... But it ain't necessarily so. Sterling K.

We believe there was a sonic boom, but it was not a British aircraft that caused it, said Lt Col Stuart Green. t was not one of ours.

[meteorite-list] Cassini Discovers Music of the Rings
http://www.newscientist.com/news/news.jsp?id=ns6639 Cassini discovers music of the rings David L. Chandler New Scientist November 9, 2004 Saturn's magnificent ring system - a huge disc resembling an old gramophone record - turns out to share another property with the LP: it constantly emits a melodic series of musical notes. The surprising discovery was made by radio and plasma wave detectors on board the Cassini spacecraft as it passed over Saturn's rings during its arrival at the planet in July. The tones are emitted as radio waves. Don Gurnett of the University of Iowa says his team reduced their frequencies by a factor of five to bring them into the range of human hearing. Gurnett says he was completely astonished when he heard the musical notes. The tones are short, typically lasting between one and three seconds, and unlike the ethereal sliding tones associated with other cosmic processes, every one is quite distinct. The evidence suggests that each tone is produced by the impact of a meteoroid on the icy chunks that make up the rings. Each hit, Gurnett says, creates a pulse of energy that is focused along the surface of a cone from the point of impact. By estimating the energy involved, he calculates that the impacting objects are about 1 centimetre across - although he cautions that his estimate could be out by as much as a factor of 10. The findings were reported on Monday at the annual meeting of the American Astronomical Society's Division of Planetary Sciences. Noisy collisions Planetary scientists have assumed that meteoroids constantly collide with Saturn's rings, says Cassini imaging team leader Carolyn Porco, and that process has been suggested as a possible cause of the shifting, spoke-like formations seen in the rings by Voyager 2. But nobody thought it would be possible to detect the impacts so directly. Cassini's close-up observations have produced a wealth of new information about Saturn's ring system, including complex details in the shapes and spacing of bands that have already revealed signs of three new moons - in addition to the three other moons Cassini had already discovered further out. The craft's discovery of one of the new moons, and a thin ring near the so-called F-ring, were reported by the International Astronomical Union on Monday. __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list

Hello List especially Denver members. They say there is a building in Denver that has a step that is exactly one mile high. I heard on the news that the ice cap is melting due to global warming and that sea level has raised three inches. I want to know if it is true, so if someone can see if that step is still one mile and not one mile and three inches, I would appreciate it. : ) Seriously, do you all think this is true, and if so, does it affect anything?

[meteorite-list] Crater question????
Tom AKA James Knudson wrote; Hello List, It seems that every meteorite made crater was first thought to be volcanic, including the craters on the moon. We all know what Barringer had to go through to prove meteor crater was in fact a meteor made crater. If you compare the crater pictured in this link with the craters on page 152 in your rocks from space book, they look quite a bit a like. I am wondering if anyone ever searched for evidence of this crater being meteoric as apposed to volcanic? It would make a fine dinosaur killer! http://goafrica.about.com/library/gallery/afar/tanzania/blgallery-afar-tanzania1.htm Geologists have studied the Ngorongoro Crater.

Re: [meteorite-list] **OT** Denver help
Hi, Since the continents do not float on the oceans, the mark will not have moved. If the mark was one mile above sea level before the three inch rise, it would now be 5279 feet 9 inches above sea level, not 5280 feet 3 inches above sea level. The statistic that sea level has raised three inches is meaningless without a since. Since yesterday? Since last year? Since 1950? Since 1900? Since 1776? Since 1066? Since The Fall of Rome? What? Actually, I believe the touted three inch rise is for the twentieth century, or a phenomenal 0.75 millimeter per year. Since I live at 441 feet above sea level, that means that the Gulf of Mexico will be lapping gently at my front doorstep in only another 179,222 years and 5 months. Guess I'd better start packing. Living in Colorado won't help. At that rate, it will get to the marker on the Colorado Capitol steps in just 2,145,792 years! Keep a weather eye out! OK, seriously, as a news item, it's just another piece of classic Global Warming Hype Scare, like today's new report that ultimately the expansion of wind power will change the Earth's climate. Both are examples of ridiculous Politico-Pseudo-Science for media consumption. 1. The Earth IS CURRENTLY IN AN ICE AGE. Do you see ice anywhere on Earth? If your answer is Yes, then IT'S AN ICE AGE! 2. The current slightly milder climatic episode is called an interglacial, meaning that during this period the ice remains but does not advance. The longest interglacial on record in the last 100,000 years is 11,200 years. This current interglacial has persisted for 10,800 years. To quote Clint Eastwood, Do you feel lucky, punk? 3. Despite insane warnings that the climate is warmer now than it has ever been in recorded human history, the climatic peak of warmth occurred about 6,000 years ago when it was 10 degrees warmer than it is now. Far from being a disaster for mankind, this peak of warmth coincides with the beginning of civilization, the founding of the first cities, the birth of agriculture, the invention of writing, science, literature, and human culture generally. 4. The normal climate for this era (the last couple of hundred thousand years) are the conditions you find if you excavate the French Riviera at the 18,000 to 25,000 year old horizon: the permafrost was six to nine feet thick and 85% of the animal bones are reindeer, about like Barrow, Alaska today. Very few bikinis in evidence. 5. Evidence from ice cores and lake varves, et cetera, shows that the turn from interglacial mildness to normal ice age conditions can happen on a time scale of less than 1 year to maybe 50 years. No one knows what triggers the return of normal ice age climatic conditions. 6. Anyone who thinks that it's a good idea for humans to intervene on a planet-wide basis to cool the Earth's climate down as much as possible is an irresponsible idiot. Having now given offense as widely as possible and seeing no other sacred cows on the horizon, I'm going to go toss some more carbon-laden fuel into my personal CO2 generator and toast my feet by its waste heat while thumbing through my well-worn copy of the works of Milutin Milankovich.
