Japoneses recolectaron muestras de asteroide. Científicos asombrados.

Científicos japoneses se quedaron sin palabras por muestras de un asteroide de 300 millones de kilómetros de distancia.

Japoneses recolectaron muestras de asteroide. Los científicos dijeron el martes que se quedaron sin palabras cuando vieron cuánto polvo de asteroides había dentro de una cápsula entregada por la sonda espacial Hayabusa-2 en una misión sin precedentes.

La sonda japonesa recogió polvo de la superficie y material del asteroide Ryugu el año pasado, a unos 300 millones de kilómetros de distancia, durante dos atrevidas fases de su misión de seis años.

Este mes la sonda envió una cápsula que contenía las muestras. Se convirtió en una bola de fuego cuando entró en la atmósfera de la Tierra y aterrizó en el desierto australiano antes de ser transportada a Japón.

Los científicos de la agencia espacial japonesa JAXA retiraron el martes los tornillos del contenedor interno de la cápsula, habiendo encontrado ya una pequeña cantidad de polvo de asteroide en la capa exterior.

Cuando realmente lo abrimos, me quedé sin palabras. Fue más de lo que esperábamos y hubo tanto que me quedé realmente impresionado, dijo el científico de JAXA Hirotaka Sawada. No eran partículas finas como el polvo, pero había muchas muestras que medían varios milímetros de ancho.

Los investigadores esperan que el material arroje luz sobre la formación del universo y quizás ofrezca pistas sobre cómo comenzó la vida en la Tierra.

Los científicos japoneses que recolectaron las muestras del asteroide aún no han revelado si el material en el interior de la sonda es igual o tal vez incluso más que los 0.1 gramos que habían dicho que esperaban descubrir.

Seiichiro Watanabe, científico del proyecto Hayabusa y profesor de la Universidad de Nagoya, dijo que, no obstante, estaba emocionado.

Hay muchas [muestras] y parece que contienen mucha materia orgánica, dijo.

Así que espero que podamos descubrir muchas cosas sobre cómo se han desarrollado las sustancias orgánicas en Ryugu.

La mitad de las muestras de Hayabusa-2 se compartirán entre JAXA, la NASA y otras organizaciones internacionales.

El resto se guardará para estudios futuros a medida que se realicen avances en la tecnología analítica.

Pero el trabajo no ha terminado para la sonda Hayabusa-2. Pues ahora comenzará una misión extendida dirigida a dos nuevos asteroides. Ya veremos que descubre.
