Remember Opportunity, the explorer on Mars? It’s sending back from great new pictures of the Red Planet.

I blogged lots last year about Phoenix, the probe on Mars that landed, found evidence of water, and died on the red planet.
There are other probes on Mars, though: the Mars Exploration Rover (MER) mission has two probes – Opportunity and Spirit – that, despite having three-month lifespans, are still rolling around four years later. In fact, they’re both heading off on their biggest journeys ever.
