Africa-Press – Comores. <\/strong><\/span>L\u2019habitat, nomme\u0301 Mars Dune Alpha, est situe\u0301 dans le centre de recherche de l\u2019agence spatiale ame\u0301ricaine a\u0300 Houston, au Texas. Ceux qui l\u2019habiteront aideront a\u0300 pre\u0301parer une future mission sur la plane\u0300te rouge. En mesurant leurs performances et leurs capacite\u0301s cognitives, la Nasa comprendra mieux les \u201cressources\u201d qui doivent e\u0302tre pre\u0301vues lors de cet ambitieux voyage, explique Grace Douglas, une responsable du programme CHAPEA, qui encadre cette expe\u0301rience. Un point crucial, compte tenu \u201cdes limites tre\u0300s contraignantes de poids que l\u2019on peut envoyer dans ces missions\u201d, ajoute-t-elle.<\/p>\n

Vrai tapis roulant pour faux astronautes<\/b><\/p>\n

La maison de 160 me\u0300tres carre\u0301s comporte une ferme verticale pour faire pousser des salades, une pie\u0300ce de\u0301die\u0301e aux proce\u0301dures me\u0301dicales, un espace de\u0301tente ou encore des postes de travail. Un sas me\u0300ne vers une reconstitution de l\u2019environnement martien. Sur le sol de sable rouge se trouvent une station-me\u0301te\u0301o, un appareil pour fabriquer des briques, une petite serre et un tapis roulant sur lequel les faux astronautes marcheront suspendus a\u0300 des sangles.<\/p>\n

Une maison pour Mars imprime\u0301e en 3D<\/b><\/p>\n

\u201cOn ne peut pas les faire marcher en rond pendant six heures\u201d, sourit Suzanne Bell, en charge a\u0300 la Nasa du programme \u201cBehavioral Health and Performance Laboratory\u201d. D\u2019apre\u0300s elle, ce tapis reproduira l\u2019effort que ne\u0301cessite l\u2019activite\u0301 physique sur Mars, mais aussi des situations de ramassage d\u2019e\u0301chantillons, de re\u0301coltes d\u2019informations ou me\u0302me de construction. Les noms des confine\u0301s volontaires ne sont pas encore connus, mais on sait de\u0301ja\u0300 que l\u2019e\u0301quipe ne sera pas constitue\u0301e d\u2019astronautes. Ils seront re\u0301gulie\u0300rement soumis a\u0300 des e\u0301le\u0301ments de stress, avec des restrictions d\u2019eau ou des pannes mate\u0301rielles.<\/p>\n

Cette maison a une autre particularite\u0301 : elle a e\u0301te\u0301 imprime\u0301e en 3D. \u201cC\u2019est une des technologies qu\u2019e\u0301tudie la Nasa pour potentiellement construire des habitats sur la surface d\u2019autres plane\u0300tes ou de la Lune\u201d, indique Grace Douglas. L\u2019agence spatiale pre\u0301pare un aller-retour vers Mars, mais le grand de\u0301part n\u2019est pas pour tout de suite. Ce voyage, qui durerait plusieurs anne\u0301es, pourrait avoir lieu \u201ca\u0300 la fin de la de\u0301cennie 2030\u201d, selon le patron de la Nasa, Bill Nelson.<\/p>\n
