Une m\u00e9t\u00e9orite martienne rare d\u00e9couverte au Niger a \u00e9t\u00e9 vendue pour la somme exorbitante de 5,3 millions de dollars lors d’une vente aux ench\u00e8res de Sotheby’s \u00e0 New York, provoquant l’indignation des scientifiques et des d\u00e9fenseurs du patrimoine culturel qui cherchent d\u00e9sormais des r\u00e9ponses et son retour.<\/span><\/strong><\/p>\n<\/div>\n

\n
\n
\n

En novembre 2023, un chasseur de m\u00e9t\u00e9orites a d\u00e9couvert NWA 16788 dans la r\u00e9gion d’Agadez, au nord\u00a0du Niger<\/strong>\u00a0.<\/p>\n<\/div>\n

\n

Il p\u00e8se plus de 24,6 kilogrammes (54 livres) et est le plus gros rocher martien jamais r\u00e9cup\u00e9r\u00e9 sur Terre, selon Sotheby’s.<\/p>\n<\/div>\n

\n

Les experts estiment qu’il a parcouru 140 millions de kilom\u00e8tres depuis la surface de Mars, probablement d\u00e9log\u00e9 par l’impact d’un ancien ast\u00e9ro\u00efde, avant d’atterrir dans les sables du Sahara.<\/p>\n<\/div>\n

<\/p>\n
\n

La vente aux ench\u00e8res a commenc\u00e9 \u00e0 1,9 million de dollars et a rapidement grimp\u00e9 \u00e0 4,3 millions de dollars, les primes et les frais portant le total \u00e0 5,3 millions de dollars.<\/p>\n<\/div>\n

\n

Cependant, Sotheby’s n’a r\u00e9v\u00e9l\u00e9 ni l’identit\u00e9 de l’acheteur ni celle du vendeur, ce qui alimente les sp\u00e9culations sur la mani\u00e8re dont un objet \u00e9tranger aussi important a quitt\u00e9 son pays d’origine.<\/p>\n<\/div>\n

\n

La vente aux ench\u00e8res a eu lieu pendant la \u00ab Geek Week \u00bb de la maison de vente aux ench\u00e8res, qui pr\u00e9sente des produits li\u00e9s \u00e0 l’histoire naturelle, \u00e0 la science et \u00e0 l’espace.<\/p>\n<\/div>\n

\n

Une galerie priv\u00e9e en Toscane, en Italie, et l’Agence spatiale italienne avaient toutes deux d\u00e9j\u00e0 expos\u00e9 la roche.<\/p>\n<\/div>\n

\n

Conversation sur les m\u00e9t\u00e9orites en Afrique<\/h2>\n<\/div>\n
<\/p>\n
\n

La provenance du sp\u00e9cimen reste toutefois un sujet de d\u00e9bat, comme le rapporte\u00a0Forbes\u00a0.<\/p>\n<\/div>\n

\n

\u00ab La m\u00e9t\u00e9orite NWA 16788 a \u00e9t\u00e9 exp\u00e9di\u00e9e et transport\u00e9e conform\u00e9ment \u00e0 la proc\u00e9dure standard de toutes les m\u00e9t\u00e9orites qui sortent du Niger.<\/p>\n<\/div>\n

\n

\u00ab Comme pour tout ce que nous vendons, toute la documentation pertinente \u00e9tait en ordre \u00e0 chaque \u00e9tape de son voyage \u00bb, explique Sotheby’s \u00e0 Forbes Africa.<\/p>\n

\n

Selon Giovanni Pratesi, professeur \u00e0 l’Universit\u00e9 de Florence en Italie et l’un des auteurs de deux des trois articles r\u00e9f\u00e9renc\u00e9s dans le catalogue de Sotheby’s, il n’a \u00e9t\u00e9 \u00ab impliqu\u00e9 que dans la caract\u00e9risation et l’\u00e9tude de ce sp\u00e9cimen (NWA 16788), sans avoir re\u00e7u, pendant un certain temps, aucune information sur sa provenance \u00bb.<\/p>\n<\/div>\n

<\/p>\n
\n

\u00ab En fait, le lieu de r\u00e9cup\u00e9ration des m\u00e9t\u00e9orites n\u2019est pas si important pour la science car leur v\u00e9ritable provenance, bien s\u00fbr, n\u2019est pas la Terre mais d\u2019autres corps du syst\u00e8me solaire \u00bb, explique Pratesi.<\/p>\n<\/div>\n

\n

\u00ab Quoi qu\u2019il en soit, il ne fait aucun doute que le Sahara repr\u00e9sente un r\u00e9servoir tr\u00e8s important de mat\u00e9riel extraterrestre.<\/p>\n<\/div>\n

\n

\u00ab Une confirmation de cela est donn\u00e9e par le nombre \u00e9lev\u00e9 de sp\u00e9cimens de m\u00e9t\u00e9orites portant le nom NWA (North West Africa) qui est utilis\u00e9 lorsque le lieu exact de r\u00e9cup\u00e9ration n’est pas connu.<\/p>\n<\/div>\n

\n

\u00c0 cet \u00e9gard, je pense que les pays africains devraient organiser un r\u00e9seau pour r\u00e9cup\u00e9rer et valoriser ces m\u00e9t\u00e9orites.<\/p>\n

\n

Cette vente a raviv\u00e9 les inqui\u00e9tudes concernant le commerce non r\u00e9glement\u00e9 des m\u00e9t\u00e9orites, en particulier celles d\u00e9couvertes dans les pays en d\u00e9veloppement.<\/span><\/p>\n<\/div>\n

\n

Les responsables nig\u00e9riens et les organismes internationaux de surveillance culturelle remettent d\u00e9sormais en question la l\u00e9galit\u00e9 et l’\u00e9thique de l’exportation de la m\u00e9t\u00e9orite, et beaucoup exigent sa restitution imm\u00e9diate.<\/span><\/p>\n<\/div>\n

\n

\u00ab\u00a0Il a \u00e9t\u00e9 d\u00e9couvert au Niger\u00a0? Comment se fait-il qu’il ait fini par \u00eatre vendu \u00e0 New York\u00a0?\u00a0\u00bb s’interroge Alia Bar\u00e9, cr\u00e9atrice de mode et fille de l’ancien pr\u00e9sident nig\u00e9rien Ibrahim Bar\u00e9 Ma\u00efnassara, aupr\u00e8s de Forbes Afrique.<\/span><\/p>\n<\/div>\n

\n
\n
\n
\n
\n

Les utilisateurs des r\u00e9seaux sociaux ont exprim\u00e9 leurs inqui\u00e9tudes quant \u00e0 la d\u00e9claration correcte de la m\u00e9t\u00e9orite aux autorit\u00e9s nig\u00e9riennes et au manque de mesures pour emp\u00eacher sa vente.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n
