Jarosite as an indicator of water-limited chemical weathering on mars
Article Abstract:
Presenting equilibrium thermodynamic reaction-path simulations that constrain the range of possible conditions under which such aqueous alternation phases are likely to have formed on mars. It is concluded that the presence of Jarosite combined with residual basalt at Meridiani Planum indicates that the alternation process did not proceed to completion, and that following jarosite formation, arid conditions must have prevailed.

Blueberry fields for ever
Article Abstract:
NASA dispatched two rovers, Opportunity and Spirit, to land at sites that were most likely to host accessible aqueous deposits. The wide areas covered in blueberries and large sulphate deposits in rocks explain the details of Mar's past climate.

The devil is in the dust
Article Abstract:
The insights into the role of 'dust devils' in injecting dust into the martian atmosphere is presented. Mars is described as a highly dynamic planet in regards with dust.
