HOUSTON.- La NASA abri\u00f3 el martes la sonda de la misi\u00f3n Osiris-Rex que recolect\u00f3 fragmentos de un asteroide y anunci\u00f3 que hall\u00f3 “polvo negro y restos” en su interior, aunque a\u00fan no ha examinado el grueso de la muestra.<\/p>\n
Siete a\u00f1os despu\u00e9s de su despegue, la sonda aterriz\u00f3 el domingo en el desierto estadounidense en Utah, tras una maniobra de alto riesgo. <\/p>\n
La muestra, tomada en 2020 del asteroide Bennu, contiene alrededor de 250 gramos de material, seg\u00fan estimaciones de la agencia espacial estadunidense.<\/p>\n
Durante aquella operaci\u00f3n, la NASA se percat\u00f3 de que la tapa del recipiente colector no pod\u00eda cerrarse. Pero finalmente se logr\u00f3 asegurar la muestra y transferir a la sonda de acuerdo con lo previsto. <\/p>\n
Sin embargo, debido a este fallo, los cient\u00edficos esperaban encontrar restos de la muestra fuera del compartimento de recolecci\u00f3n, en la caja donde estaba colocado. <\/p>\n
El martes se abri\u00f3 una primera tapa en una c\u00e1mara herm\u00e9tica del Centro Espacial Johnson en Houston, Texas. <\/p>\n
Los equipos de la NASA inmediatamente “encontraron polvo negro y restos”, anunci\u00f3 la agencia espacial, sin precisar si se trataba de fragmentos de asteroide. <\/p>\n
Este material ser\u00e1 analizado y se llevar\u00e1 a cabo un “cuidadoso proceso de desmontaje” del compartimento de recogida, “para poder acceder a la muestra principal que se encuentra en su interior”, escribi\u00f3 la agencia espacial. <\/p>\n
Est\u00e1 prevista una conferencia de prensa para el 11 de octubre para “dar a conocer la muestra”. <\/p>\n
El an\u00e1lisis de la composici\u00f3n del asteroide Bennu permitir\u00e1 a los cient\u00edficos comprender mejor c\u00f3mo se form\u00f3 el Sistema Solar y c\u00f3mo se volvi\u00f3 habitable la Tierra.<\/p>\n
Los cient\u00edficos creen que ese cuerpo espacial (de 500 metros de di\u00e1metro) es rico en carbono y contiene mol\u00e9culas de agua encerradas en minerales.<\/p>\n
Existe un peque\u00f1o riesgo (una probabilidad en 2 mil 700) de que Bennu golpee la Tierra en 2182, lo cual ser\u00eda catastr\u00f3fico. En 2022, la NASA logr\u00f3 desviar la trayectoria de un asteroide impact\u00e1ndolo.<\/p>\n","protected":false},"excerpt":{"rendered":"
