Este fragmento de casi un kilo es parte de la corteza de Marte que, tras ser expulsado del planeta rojo por un impacto, termin\u00f3 llegando a la Tierra. La roca, adem\u00e1s, es una de las muestras m\u00e1s antiguas conocidas del planeta vecino. Se estima que tiene al menos 4,100 millones de a\u00f1os.

Mientras las agencias espaciales preparan futuras misiones a Marte, algunas de las respuestas siguen llegando a la Tierra en forma de meteoritos extraordinariamente improbables.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Un an\u00e1lisis de una extra\u00f1a roca hallada&#46;&#46;&#46;<\/p>\n","protected":false},"author":1,"featured_media":519105,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[46],"tags":[],"class_list":["post-519104","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tecnologia"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
