Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.
Oppy is opening an exciting new chapter in her adventure at Cape York. Having driven down to, over and past Whim Creek, she has now explored halfway down Cape York, to a promising fin-like ridge of dark rock.
It's an active time in interplanetary exploration! Curiosity has begun roving Mars, and Opportunity's not wasting any time either. Dawn has just departed Vesta and begun the more than two-year cruise to Ceres. Juno is in the middle of a big deep-space maneuver, setting up next year's Earth flyby.
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.
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.
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.
