[VCSE-LevLista] Nem meteorit

[szilard.csizmadia at dlr.de]

Szervusztok!

A listán múlt héten elemezgettük, hogy egy ejtőernyős mellett vajon elhúzhatott-e egy meteorit. Megkésett április 1-i tréfára ugyanúgy gondoltam a reakciómban, mint arra, hogy lehetséges, hogy ez tényleg egy meteorit. Nos, az első gondolatom volt a jó. (A Tűzgömbrajongók nevű facebook-csoportban le is írtam, én nem így képzelek egy el egy friss meteoritot, visszakereshető.)

Hollandul tudók vagy a Google-fordító használói előnyben:

http://www.nrc.nl/nieuws/2014/04/08/helaas-die-noorse-skydiver-filmde-geen-meteoriet-maar-een-steen/

A lényeg: kavics került a becsomagolt ejtőernyőbe, és nyitáskor kiesett... Ez megmagyarázza, miért nem találtak a helyszínen meteoritot két év elteltével sem!

Üdv,
Szilárd

Mivel a Google-fordító a hollandot magyarra nem igazán jól, angolra viszont jól fordítja, itt az automata angol fordítás:

Unfortunately, those Norwegian skydiver filmed not a meteorite . It was a stone
clipping

The gravel that was almost two years as a possible meteorite .
by Annemarie Coevert

It seemed unique images of a unique event : a helmet camera of a Norwegian skydiver could possibly have committed a meteorite . Experts reacted with doubt ; perhaps it was just a rock . Indeed . Today it became clear that the stone was packed with the parachute accidentally.

The images were taken during a jump from the Norwegian skydiver Anders Helstrup he made in 2012. Then we see that narrowly shot what looked like a stone down Infernal Trop back .

Last week we placed a video of the Norwegian broadcaster NRK . Herein viewed Helstrup , a journalist and a geologist , once NASA employee , the films together . The latter explained why he thought he saw . Meteorite in the object

But Steinar Midtskogen , one of the creators of the video , today published a blog with the explanation of this extraordinary incident : it was not a meteorite , it was a stone .
It was a pebble , packed with the parachute

The declaration of Midtskogen was already suggested by several experts , including astronomer Alessandro Patruno : the stone comes from the backpack of the parachutist . How has this come about exactly ? Midtskogen :

    " The stone was clearly far above the parachute , as can be seen in the pictures and did not accelerate . The stone fell a few seconds after the parachute was fully expanded . So what have we overlooked ? Several people were able to discover that everything fell into place . Important clue

    A pebble at most a few centimeters was meegepikt by accident when his parachute Helstrup furled . [ ... ] And he that let go the gravel launched . While the stone on top Helstrup ended up by the wind , the parachute was held back by the ropes . Then made Helstrup his parachute a turn of 250 degrees and at that time the falling stone gets him . The stone was already a few seconds to fall and no longer accelerating . "

The full explanation of Midtskogen is read back here. He makes the comment that the exact details of the incident will never be known, but we know thanks to the insights of experts now that what at first seemed impossible , yet it proved possible : a pebble that does not seems to be accelerating , and still is .

This is a disappointment for the Norwegians behind this amazing movie ? A little bit, but the relief that finally there is clarity prevails , explains Midtskogen out :

    " The ultimate reward had been a meteorite , but honestly we sat down with a mystery for almost two years . We have searched the crowd , and thanks to this crowdsourcing the mystery is solved in all probability within days . That is insane. We are very grateful to everyone who has been involved. The creativity was excellent , and is very much appreciated . "

That the author of this post is self-deprecating movie proves that he placed there , made ​​in response to the mystery a few days ago ...
