Africa-Press – C\u00f4te d’Ivoire. <\/strong><\/span>L’Agence spatiale europe\u0301enne (ESA) a pre\u0301sente\u0301 mardi 11 fe\u0301vrier 2025 a\u0300 Toulouse son satellite Biomass commande\u0301 a\u0300 Airbus Defence and Space en 2016 et qui cartographiera, a\u0300 partir d’avril, les fore\u0302ts autour du globe afin de mesurer leur capacite\u0301 d’absorption de carbone. \u00ab\u00a0Il va mesurer les tonnes de bois par hectare contenues sur Terre, ce qui nous aidera a\u0300 mieux comprendre l’e\u0301quilibre climatique (…) afin de mieux mesurer et e\u0301valuer le climat de la Terre et les changements climatiques a\u0300 venir\u00a0\u00bb, a explique\u0301 a\u0300 l’AFP le Dr Marc Steckling, responsable de l’observation de la Terre, des sciences et de l’exploration chez Airbus Defence and Space.<\/p>\n

\u00ab\u00a0C’est vraiment un engin spatial incroyable\u00a0\u00bb<\/b><\/p>\n

Biomass permettra \u00ab\u00a0une meilleure compre\u0301hension (…) du ro\u0302le que les fore\u0302ts jouent dans le cycle du carbone\u00a0\u00bb, a souligne\u0301 Simonetta Cheli, en charge des programmes d’observation a\u0300 l’ESA. D’une masse au de\u0301collage de 1.230 kg, le satellite quittera la Terre depuis le port spatial europe\u0301en de Kourou, en Guyane franc\u0327aise, pour e\u0302tre place\u0301 sur une orbite he\u0301liosynchrone a\u0300 666 km d’altitude.<\/p>\n

Capable de cartographier l’inte\u0301gralite\u0301 de la surface terrestre en neuf mois, le satellite Biomass devrait permettre d’e\u0301tudier l’e\u0301volution des fore\u0302ts mondiales sur les cinq ans que doit durer la mission. Il analysera la biomasse forestie\u0300re avec une pre\u0301cision d’environ 200 m2, \u00ab\u00a0jamais vue auparavant\u00a0\u00bb. \u00ab\u00a0C’est vraiment un engin spatial incroyable, car faire ces mesures sur le terrain serait extre\u0302mement difficile\u00a0\u00bb, a salue\u0301 le Dr Steckling.<\/p>\n

Initialement pre\u0301vu pour 2021, retarde\u0301 par la pande\u0301mie<\/b><\/p>\n

Initialement pre\u0301vu pour 2021, le lancement du satellite a e\u0301te\u0301 retarde\u0301 notamment par la pande\u0301mie de Covid-19 et les re\u0301percussions sur la chai\u0302ne d’approvisionnement qui en ont de\u0301coule\u0301, a explique\u0301 le Dr Steckling. Outre les fore\u0302ts, Biomass sera en mesure d’observer les re\u0301serves d’eaux fossiles dans les re\u0301gions de\u0301sertiques afin d’y trouver de nouvelles sources d’eau, et contribuera a\u0300 l’e\u0301tude de la dynamique des masses glaciaires et de la ge\u0301ologie.<\/p>\n

Ses donne\u0301es, fournies en acce\u0300s libre, pourront par ailleurs aider a\u0300 mettre en \u0153uvre \u00ab\u00a0les le\u0301gislations internationales sur le climat et sur l’environnement\u00a0\u00bb, a estime\u0301 Mme Cheli, de l’ESA.<\/p>\n
