SILICON-based alien life form? Projectile hurled by little-green men? What's the fuss? A shiny rock has mysteriously materialised alongside the Mars Opportunity rover.
Admittedly, the rover has just woken up after hibernating through the Martian winter since November.
When scientists compared before-and-after photos of the ground immediately around the robotic explorer, something was out of place.
A stone.
Looks like Opportunity's 'Pinnacle Island' appeared between Sols 3536 and 3540: http://t.co/DBT2yfJ7h8 |
Not just any stone, it would seem.
It's been given the grand name "Pinnacle Island".
It has caused something of a stir among online communities.
