Los científicos han descubierto un interior fragmentado en Marte, con el manto del planeta conservando antiguos restos de su violenta formación hace miles de millones de años, según un nuevo estudio de "marsquakes" basado en los datos de la misión InSight de la NASA.

Scientists have used seismic data from NASA's InSight mission to gain new insights into the interior of Mars. Their research indicates that Mars's mantle acts as a geological time capsule, preserving evidence of the planet's formation and early history. Unlike Earth, where tectonic activity continually recycles the crust and mantle, Mars has retained much of its original structure. The study, conducted by researchers from Imperial College London and collaborators, used artificial intelligence to analyze marsquake data, revealing a complex, non-uniform internal structure. These findings provide a rare glimpse into the early history of rocky planets and offer new perspectives on planetary evolution.

Cómo un estudio de los "marsquakes" ayudó a revelar una cápsula del tiempo geológica

Los científicos han descubierto nuevos detalles de esta misión a Marte que despegó en 2018. Dicen que el manto de Marte ha creado una cápsula del tiempo geológica de cuando se formó el planeta hace miles de millones de años. Lo que encontramos fue bastante inesperado. Y ofrece pistas tentadoras sobre algunos de los mayores interrogantes de la exploración espacial. Una de las preguntas fundamentales es: ¿estamos solos? Y relacionada con ésta, ¿hasta qué punto es única la Tierra? La investigación, basada en los datos de la misión InSight de la NASA, desafía los modelos tradicionales de planetas rocosos como estructuras de capas suaves. Este audio de un terremoto en Marte, es decir, cualquier actividad sísmica que sacuda el suelo de Marte, muestra retrasos e interferencias, lo que indica un patrón fractal en lugar de uno uniforme. Lo que hemos conseguido aquí en este nuevo estudio es la mirada más detallada, la mirada más fina que hemos tenido en el interior de un planeta rocoso, planetas rocosos como Marte, Venus, Mercurio. Constantino Charalambos es investigador del Imperial College de Londres. Dice que cuando Marte se selló, preservó un interior que contenía restos de una cápsula del tiempo geológica. Estos son probablemente escombros, o estamos viendo las secuelas de estos colosales impactos. Y son productos de océanos de magma que cristalizaron hace más de cuatro mil quinientos millones de años. A diferencia de la Tierra, donde las placas siguen inyectando materiales nuevos y reciclados. Así que básicamente, en la Tierra, la historia ha sido reescrita mil veces, mientras que en Marte, estamos viendo este registro más prístino, este primer borrador de su historia que aún se conserva allí. El estudio fue analizado por investigadores del Imperial College de Londres y colaboradores mediante inteligencia artificial. Lo explica Tom Pike, profesor del Imperial College de Londres. Todo lo que sabíamos era lo que teníamos en la Tierra, y ahora hemos puesto el segundo punto de datos aquí. Y el hecho de que sea bastante diferente, creo, es muy interesante y nos da una perspectiva de lo especial que puede ser la Tierra.
