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.

Dusty girl

Posted by Emily Lakdawalla on 2012/01/23 05:32 CST

Today Opportunity sent back to Earth the last few frames of the "deck pan" self-portrait she took during the waning days of 2011. Her solar panels are very dusty, which isn't helpful. It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.

Curiosity in context: Not exactly "Viking on wheels," but close

Posted by Emily Lakdawalla on 2011/11/21 06:51 CST
