A picture of Spirit that's too poetical for words

Emily Lakdawalla • May 25, 2011

Yesterday, I remarked that despite the declaration of her death we'll be seeing Spirit frequently over the next few years, as long as Mars Reconnaissance Orbiter is still monitoring her landing site with its HiRISE camera. I said that Spirit is a lump that's relatively easy to spot because of her dark shadow. Well, Spirit's managed to make herself even easier to spot than that.

Sad news for Spirit: It's All Over But the Crying

A.J.S. Rayl • April 30, 2011

As Opportunity drove her little robot heart out, breaking the 28-kilometer mark on her odometer, and driving the longest backward drive ever, April proved to be another month of exhilarating highs for the Mars Exploration Rover mission and one extended low with only silence from Spirit, despite intensified efforts by her Earth crew to establish contact.
