Tal vez Superman fuera capaz de ver a trav\u00e9s de las paredes con su visi\u00f3n de rayos X, pero los cient\u00edficos europeos han desarrollado una capacidad a\u00fan m\u00e1s llamativa. Con la sonda del radar MARSIS de la sonda orbital Mars Express, de la ESA, pueden ver a trav\u00e9s de varios kil\u00f3metros de hielo o roca s\u00f3lida.<\/p>\n<\/div>\n

Hasta hace poco tiempo, s\u00f3lo era posible explorar la superficie de un planeta. La \u00fanica manera de obtener informaci\u00f3n acerca del subsuelo era posarse en la superficie y empezar a cavar o perforar. Sin embargo, esos m\u00e9todos s\u00f3lo permit\u00edan sondear hasta una profundidad de tal vez medio metro, y esto s\u00f3lo se pod\u00eda realizar en un punto determinado de todo un planeta.<\/p>\n

MARSIS, el primer instrumento de su claseen orbitar en torno a otro mundo, ha demostrado que es posible mirar bajo la superficie de un planeta entero desde la \u00f3rbita. Ahora, al disponer de mayores conocimientos sobre las posibilidades que ofrece una sonda de radar, el equipo de la MARSIS se plantea empezar a explorar otros objetos del Sistema Solar.<\/p>\n

The interiors of asteroids and comets could be thoroughly scanned by a radar sounder. Here on Earth, the MARSIS technique could be invaluable for studying Antarctic ice sheets. For the first time, there is the potential for three-dimensional studies of planets and moons \u2013 thanks to radar\u2019s see-through vision.<\/p>\n

La luna de J\u00fapiter, Europa, es uno de los lugares donde un instrumento como MARSIS podr\u00eda obtener resultados espectaculares. Europa contiene un oc\u00e9ano (\u00bfcon vida?) debajo de su gruesa y helada corteza. El radar tambi\u00e9n podr\u00eda medir la profunidad de los lagos de hidrocarburo de Tit\u00e1n, la luna de Saturno. Tambi\u00e9n podr\u00eda estudiar los potentes g\u00e9iseres que brotan en Enc\u00e9lado, otra de las lunas de Saturno.<\/p>\n
