Genesis a coute plus de 250 millions US et beaucoup de chercheurs & d'etudiants gradues ont du pleurer ce jour la (le 9 sept dernier)
L'analyse preliminaire vient d'identifier la cause probable, une erreur de design GROSSIERE qui a fait qu'un capteur qui devait declancher un parachute avait ete monte A L'ENVERS.
The sensors, which are estimated to be less than an inch (2.5 centimetres) wide, were apparently installed in a circuit board in the wrong orientation - rotated 180° from the correct direction. But the problem stemmed not from the installation but the design, by Lockheed Martin, based in Bethesda, Maryland.
