After spending much of October driving around and taking pictures on Matijevic Hill, Opportunity hunkered down for Halloween and spent the holiday quietly, staying out of mischief's way and the Mars Exploration Rovers (MER) mission roved another month closer to its ninth anniversary of working on the surface of the Red Planet.

Sols 3060 - 3088

Posted by A.J.S. Rayl on 2012/10/03 01:58 CDT | 1 comments

On reconnaissance of Matijevic Hill, Opportunity has driven right into another Martian mystery, compete with new kinds of “berries," tiny white veins running through two distinctive outcrops of rock, and orbital data indicating that somewhere here clay minerals are hiding, all of which has put the Mars Exploration Rover (MER) mission back in the science spotlight and made for another September to remember at Meridiani Planum.

I know it’s been all Curiosity, all the time on this blog for the last couple of weeks, and that’s not likely to change much for the next couple of weeks. But I don’t want people to forget that there’s another rover exploring Mars’ ancient geology. Opportunity has been taking spectacular photos of Whim Creek and Endeavour Crater this last week.

Oppy close to the edge…

Posted by Stuart Atkinson on 2012/06/05 10:00 CDT

Since you last visited, Opportunity has continued to drive downhill – well, what passes for ‘downhill’ on Cape York! – and is now not far at all from the northern edge of the Cape. From where she is now she sees the Meridiani desert stretching away to the north and west, the eastern hills on her right, and the Cape itself behind her. And around her? lots and lots of Homestake-like gypsum veins.

An update on Opportunity, and a plea for some volunteer desktop publishing help

Posted by Emily Lakdawalla on 2012/04/03 05:00 CDT | 2 comments

A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.
