Mars: Blueberry fields for ever
Jeffrey M. Moore1
Abstract
The Mars saga continues. The latest finds — wide areas covered in balls of haematite, or 'blueberries', and large sulphate deposits in rocks — enable us to draw in more details of the planet's past climate.
We have known for thirty years that channels and valleys were carved into the martian landscape long ago by a fluid that was probably water. But unambiguous evidence for aqueous deposits has been frustratingly lacking.
- Jeffrey M. Moore is at the NASA Ames Research Center, MS 245-3, Moffett Field, California 94035, USA.
