It has now started to get so much junk that circulates in low orbit that there is serious risk to satellites damaged by loose, flying parts, screws, nuts or metal shrapnel coming still in 10,000 km / h in relative speed. space museum huntsville The story of a space shuttle who went on a "chip" of a paint chip that hit the windshield of several thousand space museum huntsville kilometers per hour is now a classic. The glass was, fortunately, thick enough. Space shuttles meet routinely as scrap and are often forced to make evasive maneuvers around known scrap swarms The famous stone chip in the box on the space shuttle Challenger STS-7 from 1983. The number of similar brand of accidents has increased markedly after 1998. Space ferries are routinely forced to make evasive maneuvers to not get hit by famous cloud of splinters. Big and small space junk divided into large and small pieces. What makes a piece of "big" is not so much with the size to do as our ability to detect pieces smaller than a certain size. Normally considered "large" be the subject of greater than 10 centimeters, with a mass of more than one kilogram. One would think that "small" pieces were everything that was less than that, but instead has chosen approximately one centimeter. Objects lying between these sizes also tend to be considered "great" but we can not detect them with current methods. space museum huntsville The large amount of objects are small. NASA concluded in 2009 that the number space museum huntsville of large objects space museum huntsville is about 19,000 pieces, space museum huntsville objects between 1 and 10 centimeters approximately 500,000 pieces, while the number of small objects is probably over a million. The total known mass of all the space junk is about 1900 tonnes and is mainly concentrated to a number of large objects. There are about 1,500 items, or 98% of all objects, weighing 100 pounds or more in low orbit. The real bamsingarna is obviously burned-out rocket stages that would have crashed but did not, dead satellites and the like, while the most dangerous perhaps is part of the explosive satellites (ASAT anti-satellite weapon) that walketh with thousands of meters per second after being thrown away from a nuclear explosion . All collisions between small or large pieces causing space museum huntsville new pieces that continues to spread its deadly threat in space. Low Orbit (LEO, Low Earth Orbit) are the heights that most earth resource satellites, Iridium, with multiple uses, and that's about where Space Shuttle can reach .. LEO extends definition between 160 and 2000 km above the Earth's surface. space museum huntsville Here are the majority of our satellites and thus the majority space museum huntsville of the debris. The International Space Station is located, for example, and bobbing at altitudes between 319 and 347 km altitude. Accidentally debris micrometeorites hitting enter through a spaceship and kills the crew, or a satellite receiving a hole right through because of a collision has mostly belonged T Science Fiction short story the v
