That was how it started a discussion about a strange rock that appeared in photographs taken by the robot Opportunity , which rolls by Mars since January 2004. Now, NASA scientists discovered that was rover , and when stepping from a higher rock which designed the piece of rock for that location.

A photograph taken from the ground by Mars rover on January 8 showed a rock four inches, with a strange look. When the scientists compared that

picture with another of the same place, taken four days earlier, found that the rock was not there before.

After much discussion on the rock (several theories for the origin of rock emerged from being a shard of the result of a meteorite impact, to be a being-alive), which received the name of Pinnacle Island, scientists NASA explained on Friday, thanks to new photos, which after all was all the fault of Opportunity .

“So we move Opportunity , and then inspecting the Pinnacle Island, we could see directly into the hillside up a rollover with the same unusual looking rock,” said Ray Arvidson, principal investigator at <> Opportunity , of Washington University in St. Louis. “We went up there. You can see the marks [left by Opportunity ]. That is where Pinnacle Island comes. “
