Los hallazgos en Marte

El rover Curiosity fue lanzado al espacio hace 10 años. Sus grandes descubrimientos alentaron a las autoridades de la NASA a enviar a Marte a su gemelo: Perseverance. ¿Qué se sabe sobre el planeta?

El rover Curiosity fue lanzado al espacio hace 10 años. Sus grandes descubrimientos alentaron a las autoridades de la NASA a enviar a Marte a su gemelo: Perseverance. ¿Qué se sabe sobre el planeta?

Después de más de una década de trabajo intenso para su fabricación, la principal agencia espacial del mundo reveló 5 datos clave obtenidos de las expediciones.

Se detectaron moléculas orgánicas en muestras de rocas recolectadas del cráter Gale. Su presencia en Marte sugiere que el planeta pudo haber albergado vida.

Compuestos orgánicos

1

Los científicos han detectado fluctuaciones en la abundancia de metano, aunque Curiosity no está equipado para determinar si fue originado a partir de procesos biológicos.

Variabilidad del metano

2

Datan de aproximadamente 4 mil millones de años. Esta información científica puede descifrar cambios inducidos por la radiación en los compuestos orgánicos e identificar firmas biológicas.

Formación rocosa

3

También ha arrojado luz sobre cómo el planeta se ha secado. Parte de esa evidencia es la presencia de jarosita, un mineral que sólo se forma en ambientes acuosos.

Agua en Marte
