Martian Blueberries - Crunchy on the Outside. Soft in the Middle.

Scientist exam strange spherical formations on the Martian surface. It seems to baffle geologists, who seem to have no solid hypothesis.

"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."

"The fact that they have layers of a mineral called hematite suggests that the spherules were formed by the action of mineral-laden water percolating through rocks. That's how similar spherules formed on Earth, where they're known as thunderballs, shaman stones or Moqui marbles."

Will this be a key into answering the question, "is there life on mars?" It may be an easy introduction for the sheeple.
