[Tech] Spirit fotografa un 'UFO' nei cieli di Marte

Secondo gli scienziati potrebbe trattarsi del primo meteorite ripreso dalla superficie di un altro pianeta, o forse della sonda Viking 2, spedita su Marte circa 30 anni fa e tuttora in orbita polare intorno al pianeta.

"We may never know, but we are still looking for clues," said Dr Mark Lemmon, from Texas A&M University.



Whatever it was, Spirit was lucky to catch sight of the UFO as the rover's main mission is to look downwards to study rocks and soil on the planet.



Only occasionally does it raise its sights towards the sky to study the atmosphere of Mars.



But it was on just such an occasion when Spirit was observing the sky with the green filter of its panoramic camera that the roving geologist came across the surprise - a streak across the peach-coloured Martian heavens.
