Answer:

Explanation:

La exploración intensiva a la que se está sometiendo el planeta Marte nos está revelando gran cantidad de datos sobre sus propiedades y sobre su pasado. Sin embargo, existen dos grandes incógnitas por desvelar: ¿cuáles fueron las diferencias que provocaron que el planeta sea tan distinto de la Tierra? ¿Existe o ha existido actividad biológica en el planeta rojo? Especialmente revelador es el estudio comparativo de ambos planetas.

Desde la distancia, la Tierra y Marte nos muestra profundas diferencias. En el primer caso, dominan blancos y azules, correspondientes a las nubes y a los océanos, y los marrones de los continentes. Por tanto, la existencia de agua en sus diferentes estados (sólido en los casquetes polares, líquido en los mares y gaseoso en la atmósfera) es evidente. Y la presencia de agua sugiere, de manera casi inmediata, la existencia de vida. De hecho, incluso desde satélites en órbita es posible apreciar la intensa actividad biológica del planeta, como es el caso de las banquisas antárticas o el cambio estacional de la superficie forestal.
