Meteorite Causes Illness in Peru

eldavojohn writes "A meteorite struck in Peru on Saturday leaving cinders, rock & water boiling out of the ground. Villagers nearby reported headaches & vomiting and attributed it to the event. From the article, 'Seven policemen who went to check on the reports also became ill and had to be given oxygen before being hospitalized, Lopez said. Rescue teams and experts were dispatched to the scene, where the meteorite left a 100-foot-wide (30-meter-wide) and 20-foot-deep (six-meter-deep) crater, said local official Marco Limache.' It's not yet clear whether this is from the meteorite, gas trapped underground that was released or a chemical reaction between the two."

    Ah, I suspect this was either not a meteorite or there is something else going on given that any meteor leaving a 30 meter wide and 20 foot deep crater (meteor being approximately 30 inches wide) is not going to hit the ground steaming hot. On the contrary, it will be cold as ice (or colder) given its composition and time for heating. However, I suppose it could also be a re-entry event from a satellite carrying a toxic payload like plutonium... After all, we have the remnants of many satellites and the debris associated with them still in decaying orbits and you can easily spot many of them. Some satellites particularly those from the former Soviet Union and China have a history of toxic components. Though I suspect we'll know soon enough if it were a satellite, it would have been tracked by numerous agencies and individuals who monitor that sort of thing.

Extra power to run control systems was supposed to come from outside sources. A reactor near meltdown under some configurations may be producing much less power than usual and so this test had applicability to some meltdown research, but this particular design, in weapons production mode, would also have greatly reduced spare power for control in normal operation, so this test was probably to confirm the military applications of Chernobyl 4.

      A couple of fairly close descriptions are here already, but let me take a stab at it.

      The Chernobyl test was to see if they could power all the plant from the momentum of the turbine after an emergency shut-down of one reactor before powering up another reactor. To do this, they had to take a reactor off-line. They gradually reduced its power output, but just before taking it off, there was some bureaucratic reason why they had to delay the test for 12 hours or so. This caused a problem, because at the low power the reactor was down to, "nuclear poison" build up which slows the reaction. After a point can leads to a complete stop, ruining all the fuel in the reactor. When it was time to perform the test the reactor power started dropping precariously, and to keep the power up, the ended up removing NEARLY ALL the control rods, FAR in excess of the number they are allowed to remove. At that point the water and the nuclear poison were slowing the reactions in place of the control rods. To perform the test, they also had to stop the water circulation that goes to the turbine. Eventually, the power level stabilized, as the nuclear poison started reacting more without the control rods. Then power started increasing, until in a matter of seconds all the nuclear poison was gone. Then, without the water circulation, steam bubbles formed as well, removing the water from between the fuel rods, making there be practically nothing in place to restrain the reaction. The meltdown happened well before there was a chance to replace the control rods, blowing many of the control rods out the top of the building. There were other factors, but I believe these are the central ones. Summary: Unsafe design + Unsafe operation + No containment building = bad.

    Actually the winds were moderate when the Tacoma Narrows bridge collapsed.

    It could be said that the bridge was designed to collapse, but not intentionally. The designers failed to take in to account the effect of resonance. From the wikipedia article here:

    "Preliminary construction plans had called for 25-foot-deep (7.6 m) girders to sit beneath the roadway and stiffen it. Moisseiff, respected designer of the famed Golden Gate Bridge, proposed shallower supports -- girders 8 feet (2.4 m) deep. His approach meant a slimmer, more elegant design and reduced construction costs. Moisseiff's design won out. On June 23, 1938, the PWA approved nearly $6 million for the Tacoma Narrows Bridge. Another $1.6 million was to be collected from tolls to cover the total $8 million cost.

    The decision to use the shallower girders proved to be the first bridge's undoing. With the 8 foot (2.42 m) girders, the roadbed was insufficiently rigid and was easily moved about by winds. From the start, the bridge became notorious for its movement. A mild to moderate wind could cause alternate halves of the center span to visibly rise and fall several feet over 4 to 5 second intervals. This led to the bridge being referred to as "Galloping Gertie" by the local residents, due to the apparent "galloping" motion felt by the drivers on the roadway."

    The winds were considered moderate for the day 40-42mph, however they were steady allowing the destructive resonance to build. The bridge was considered strong enough to withstand hurricane force winds. It was not the strength of the wind but the design of the bridge that led to the collapse.

The fear of contaminating Jupiter's moons, especially Europa, spurred NASA to decide to plunge the probe into Jupiter's atmosphere rendering it harmless. This occurred almost four years ago to the day (Sept. 21, 2003).

All of them would have a shallow entry angle that would result in a low velocity for anything that did hit the ground.

    As you speculated, when events like this are reported, the various space agencies are usually very quickly able to identify possible satellites that may have entered during a given time frame. For example, a Russian booster entered over my home county about 10 years back. It had already been identified the next morning. Incidentally, it burned up completely. No crater.

    Regarding a plutonium carrying satellite. Although I've mentioned such couldn't account for such a crater, there have been quite a few put into space. Cosmos 954, which failed to reach orbit and disintegrated over Canada (note that it was not designed to survive re-entry) is a notable example, but the Russians built dozens of these satellites. Actually, the Cosmos RORSATS were powered by uranium-fueled nuclear reactors, not plutonium RTG's. Anyway, when the RORSATS reached the end of their life, the fuel bundle was actually ejected by a small rocket into a 1000 km disposal orbit, which will delay their re-entry by several hundred more years. I suppose most of the satellite bodies themselves have already re-entered.

    Interestingly, this has been found to be a rather major source of space debris, as some of the liquid sodium coolant was ejected simultaneously with but free from the core. Once free from the heat of the reactor, the liquid sodium hardens into little metal spheres.

The village was built into the side of a mountain. The stream ran through the town, and water had been diverted into the pools on a series of cultivated terraces that led up to the monastery. There was no sign of life in the steep winding street or by the pools. The valley was littered with large boulders which would serve as cover if necessary, but he did not expect resistance on a military level. He lowered his glasses, signaling for the men to follow.

    They crossed a stone bridge two at a time, covered by the men behind them. If any defenders were going to open fire, now would be the time and place to do it. Beyond the bridge the street twisted up the mountainside. On both sides there were stone huts, many of them fallen into ruin and obviously deserted. As they moved up the stone street, keeping to the sides and taking cover behind the ruined huts, Yen Lee became increasingly aware of a hideous unknown oder. He motioned the patrol to halt and stood there sniffing.

    Unlike his counterparts in western countries, he had been carefully selected for a high level of intuitive adjustment, and trained accordingly to imagine and explore seemingly fantastic potentials in any situation, while at the same time giving equal consideration to prosaic and practical aspects. He had developed an attitude at once probing and impersonal, remote and alert. He did not know when the training had begun, since in Academy 23 it was carried out in a context of reality. He did not see his teachers, whose instructions were conveyed through a series of real situations.

    He had been born in Hong Kong and lived there until age twelve, so that English was a second language. The his family had moved to Shanghai. In his early teens he had read the American Beat writers. The volumes had been brought in through Hong Kong and sold under the counter in a bookshop that seemed to enjoy freedom from official interference, although the proprietor was also engaged in currency deals.

    At the age of sixteen he was sent to a military academy, where he received intensive training in the use of weapons. After six months he was summoned to the Colonel's office and told that he would be leaving the military school and returning to Shanghai. Since he had applied himself to the training and made and excellent showing, he asked the Colonel if this was because his work had not been satisfactory. The Colonel was looking not at him but around him, as if drawing a figure in the air. He indicated obliquely that while a desire to please one's superiors was laudable, other considerations were in certain cases even more highly emphasized.

    The smell hit him like an invisible wall. He stopped and leaned against a house. It was like rotten metal or metal excrement, he decided. The patrol was still in the ruined outskirts of the village. One man was vomiting violently, his face beaded with sweat. He straightened up and started toward the stream. Yen Lee stopped him: "Don't drink the water or splash it on your face. The stream runs through the town."

    Yen Lee sat down and looked once again at the town through his field glasses. There were still no villagers in sight. He put his glasses down and conducted an out-of-body exploration of the village - what westerners call "astral travel." He was moving up the street now, his gun at the ready. The gun would shoot blasts of energy, and he could feel it tingle in his hands. He kicked open the door.

    One glance told him that interrogation was useless. He would get no information on a verbal level. A man and a woman were in the terminal stages of some disease, their faces eaten to the bone by phosphorescent sores. An older woman was dead. The next hut contained five corpses, all elderly.
