El \u201cloco proyecto\u201d de desarrollar la tecnolog\u00eda capaz de desviar la trayectoria de un asteroide que, pongamos, venga directo contra la Tierra, dar\u00e1 un gran paso para la Humanidad este lunes con el lanzamiento desde la estaci\u00f3n de Cabo Ca\u00f1averal \u2015y si la imprevisible meteorolog\u00eda de la Florida no lo impide\u2015 de la misi\u00f3n Hera, de la Agencia Espacial Europea (ESA)<\/a>. Lo har\u00e1 a bordo de un cohete Falcon9 de SpaceX y cuando llegue a su destino dentro de un par de a\u00f1os, la sonda se dedicar\u00e1 a estudiar la mella que produjo el impacto cin\u00e9tico, el 26 de noviembre de 2022, de la nave DART, de la NASA, <\/a>contra un asteroide llamado Dimorphos, cuya \u00f3rbita logr\u00f3 alterar 32 minutos. Aquel fue un logro hist\u00f3rico que ahora toca analizar a fondo.<\/p>\n

Las comillas de \u201cloco proyecto\u201d son del italiano Ian Carnelli, director de Hera<\/i>,<\/a> que se paseaba este domingo por las zonas comunes de un hotel en Cocoa Beach, kitsch<\/i> ciudad de vacaciones al lado de Cabo Ca\u00f1averal, con una comprensible mezcla de emoci\u00f3n y nervios alimentados por una incertidumbre \u00faltima hora: una tormenta tropical, llamada Milton<\/i>, se ha formado durante el fin de semana en el Golfo de M\u00e9xico y tocar\u00e1 tierra, previsiblemente el mi\u00e9rcoles por la tarde, en la Costa Oeste de Florida convertido en un hurac\u00e1n de categor\u00eda 3 (de un m\u00e1ximo de 5). El mal tiempo oblig\u00f3 a suspender las actividades de la jornada previa al lanzamiento, que podr\u00eda verse aplazado ante una probabilidad de \u00e9xito, ciertamente baja a \u00faltima hora del domingo, del 15%, seg\u00fan los ingenieros de SpaceX.<\/p>\n

As\u00ed que Carnelli ya no sab\u00eda c\u00f3mo cruzar los dedos. \u201cEl despegue de Hera<\/i> ser\u00e1 el final de un viaje que empez\u00f3 en 2004\u201d, dec\u00eda. \u201cAunque lo m\u00e1s loco es que hayamos sido capaces de montar una misi\u00f3n espacial en solo cuatro a\u00f1os, los que han pasado desde que recibimos los permisos y la financiaci\u00f3n. Normalmente, algo as\u00ed toma entre siete y 12 a\u00f1os y puede costar hasta 800 millones de euros\u201d. La inversi\u00f3n en el proyecto Hera ha ascendido a 363 millones. Y la cosa, desde luego, corr\u00eda prisa: este 7 de octubre se abre una ventana orbital para lanzar la astronave que se cerrar\u00e1 el 27 de este mes. \u201cSi no la aprovechamos, tendremos que mandar el sat\u00e9lite a un museo. Cuando expire ese plazo, ya no ser\u00e1 posible alcanzar Dimorphos\u201d, explica Carnelli.<\/p>\n
