You may remember the $2.5 billion Curiosity rover currently drilling rocks on the Red Planet already found strange shiny things and what was labelled a 'Martian Flower'. But if anything, this is even weirder. An image posted by Nasa on 30 January and taken with the right Mastcam on Curiosity shows what appears to be a 0.5cm metal spoke protruding out of a rock. The strange sight - which looks a bit like a robotic arm - was noticed by imaging editor Elisabetta Bonora from Italy. Whatever it is looks shiny, casts a shadow on the rock below and looks different to the rock it emerges from. Universe Today speculates that it might be a different type of rock more resistant to erosion. Gizmodo instead wonders aloud whether it's evidence of an alien death ship.[/quote] [i]Or[/i] what appears to a rock resistant to erosion. I'm sure you're thinking "It's just a rock".
