I like this "proposed future roadmap" for Opportunity. :-) From Larry Crumpler's latest blog post:

Proposed Japanese life-search mission to Mars, called MELOS. Would include methane/biosignature detection and a fluorescence microscope.

The Spirit rover may have finished its journey a long time ago, but there is still plenty of data to go through and analyze, and continued study of that data has provided more evidence for one of the rover’s most significant findings: ancient hot springs in this area inside Gusev crater. Hot springs, as on …

More evidence that the Spirit rover found ancient hot springs on Mars, close to the Home Plate outcrop.

a chronicle of planetary exploration
Introduction
The Meridiani Journal is a chronicle of planetary exploration and discovery, both in our own solar system and beyond.

The name is derived from the desert plains of Meridiani Planum on Mars, where the Opportunity rover landed in 2004.

Many recent discoveries, such as the geysers of Enceladus, the subsurface ocean of Europa, the methane lakes and seas of Titan and the growing number of exoplanets found orbiting other stars make this an exciting time of exploration and discovery.

TMJ is published by space writer and blogger Paul Scott Anderson, a life-long space exploration supporter and member of The Planetary Society. He also writes for The Spaceflight GroupAmericaSpaceUniverse Today and Examiner.com.
