It’s already been baptized Neuschwanstein and it has been found only six kilometers (about 4 miles) from (Ludwig II.‘s) famous castle near Füssen (in Bavaria) after a systematic search. The baby meteorite Neuschwanstein is part of a bigger celestial body which may have weighed 600 kg and whose extremely luminous path in the sky was widely observed on April 6, 2002 at about 22:20 hrs CET over Southern Bavaria and Austria. © by DLR –The picture shows the fragment of the meteorite that fell on April 6 and which has been found after a systematic search near Castle Neuschwanstein. According to the place of find, it was named Neuschwanstein. This fragment was found only because of a well-planned, systematic search that was initiated by the German Center for Air And Space Travel (DLR). To make this possible, DLR scientists in Berlin-Adlershof use in particular the data of the European Fireball Network, which regularly surveys the night skies over Central Europe to search for (bright) meteors. Seven pictures of the European Fireball Network taken during the night of April 6 wre successfully chosen for model computations of the possible location of impact. The result was: Several fragments of the meteoroid’s original mass of about 600 kg with an overall total of about 20 kg must have survived the plunge (through the atmosphere) and must have reached the ground (intact). The place of impact of the main mass of the meteorite could be narrowed down to an area of about 700 x 1,000 meters east of Hohenschwangau near Füssen, in a mountainous, hard to reach area. It was only after several systematic search expeditions that the first partial mass could be recovered on July 14th and which was now presented to the press under the name of Neuschwangau. This is the first time in Germany that a meteorite could be recovered on the basis of photographic observations and model computations. As the partial mass of Neuschwanstein has been found only about two kilometers from the predicted point of impact of the main mass, the DLR scientists hope to find the main mass too. It is estimated to weigh about 15 kg. According to the DLR scientists, the recovered partial mass remained undamaged because there was a snow blanket about 1 meter (ca. 40 inches) deep into which it impacted on April 6. The rusty stains on its surface developed after it fell and hint at metal-containing material. Neuschwanstein only a fragment of an asteroid measuring 600 meters? According to the DLR researchers from Berlin-Adlershof, the chemistry and petrology of the precious, extraterrestrial find will now be analysed painstakingly in order to classify it appropriately. In this context, a comparison with the Pribram meteorite (H5) will be of particular interest. This meteorite fell 43 years ago on April 7, 1959, was also photographed by fireball survey cameras and later found in (the former) Czechoslovakia. The model computations showed that the orbital elements of Neuschwanstein are almost identical to those of Pribram, something extraordinary with regard to meteorites. This discovery could well mean that there is an entire stream of meteoritical pieces that possibly formed when a small asteroid broke apart. The work now done in the lab should determine whether both meteorites stem from the same parent body and how long ago the fragmentation of the parent body occurred. Statistical considerations predict that there should be about 1 billion meteorites of similar composition corresponding to an asteroid measuring about 600 meters in diameter.
