L'espace est tellement vaste qu'un aller-retour \u00e0 destination de Mars, l'une des plan\u00e8tes les plus proches, peut durer plusieurs ann\u00e9es. Avant que des astronautes puissent r\u00e9aliser des voyages aussi longs et p\u00e9rilleux, il est judicieux de tenter de conna\u00eetre autant que possible les probl\u00e8mes auxquels ils seront confront\u00e9s. C'est pour cette raison que l'ESA envisage de s'associer aux Russes pour envoyer un \u00e9quipage sur Mars au printemps de l'ann\u00e9e 2008.<\/p>\n<\/div>\n

Non, cette mission n'est pas r\u00e9elle. Il s'agit d'une simulation de vol baptis\u00e9e Mars500. Pendant ce \u00ab voyage \u00bb de 500 jours, l'\u00e9quipage vivra et travaillera sur un site d'isolement sp\u00e9cial situ\u00e9 \u00e0 Moscou. Enferm\u00e9s dans des caissons m\u00e9talliques, les volontaires devront faire face \u00e0 de nombreuses situations susceptibles de se produire pendant un voyage \u00e0 destination de la Plan\u00e8te rouge. Ceci signifie qu'ils devront \u00ab vivre \u00bb un lancement, un voyage 'aller' de 250 jours, une exp\u00e9dition sur la surface martienne et un long retour sur Terre.<\/p>\n

ESA s'efforce maintenant de d\u00e9terminer des exp\u00e9riences scientifiques qui permettront d'en savoir plus sur la tension mentale et physique suscit\u00e9e par une mission de telle dur\u00e9e, et sur les solutions possibles. Par exemple, comment les astronautes arriveront-ils \u00e0 vivre loin de chez eux, dans un espace aussi restreint ? Comment r\u00e9agiront-ils face aux urgences soudaines et \u00e0 des d\u00e9lais de communication pouvant atteindre 20 minutes ? Pourront-ils survivre avec des r\u00e9serves limit\u00e9es de boisson et de nourriture, sans espoir de r\u00e9approvisionnement ? Souffriront-ils de sautes d'humeur et d'insomnies ? Finiront-ils par se disputer et se brouiller ? Vous le saurez bient\u00f4t\u2026<\/p>","protected":false},"excerpt":{"rendered":"
