The discovery of a collection of strange spherical objects on Mars has caused a stir over at NASA.
Despite all the fuss made over the Curiosity rover in recent months, the discovery has actually come from earlier rover Opportunity.
The strange spheres resemble earlier objects – the ‘blueberries’ – which were discovered to be rich in hematite.
Yet these new discoveries are fundamentally different.
Steve Squyres of Cornell University in Ithaca stated:
[quote]This is one of the most extraordinary pictures from the whole mission. They are different in concentration. They are different in structure. They are different in composition. They are different in distribution. So, we have a wonderful geological puzzle in front of us. We have multiple working hypotheses, and we have no favorite hypothesis at this time. It’s going to take a while to work this out, so the thing to do now is keep an open mind and let the rocks do the talking.[/quote]
More as NASA discover it.
