Opportunity is healthy. The solar array was apparently cleaned again on sol 638. Average solar array energy is around 720 watt-hours after the cleaning event!
Opportunity finished a campaign using the robotic arm on a cobble called "Antistasi." The Moessbauer spectrometer and alpha particle X-ray spectrometer data show that the cobble is very basaltic.

On Sol 645 Opportunity drove 22 meters (about 72 feet) south on an outcrop path around "Erebus Crater." This drive pushed Opportunity's total driving distance past the four-mile mark.

Sol-by-sol summaries


Sol 641 (Nov. 12, 2005): Opportunity unstowed the robotic arm, changed tools to the Moessbauer spectrometer and did a Moessbauer integration on a cobble called Antistasi.

Sol 642: The rover continued the Moessbauer integration on Antistasi up to the afternoon Mars Odyssey pass. It changed tools to the alpha particle X-ray spectrometer and started an overnight integration on Antistasi.

Sol 643: Opportunity changed tools to the Moessbauer spectrometer and started an integration. The rover then monitored dust with the panoramic camera and imaged surrounding cobbles.

Sol 644: The Moessbauer integration on Antistasi continued and panoramic-camera imaging of the surrounding outcrops was conducted.

Sol 645: Opportunity drove about 20 meters (about 66 feet) on an outcrop path so the rover would be able to analyze the outcrops more with the panoramic camera. Also, the panoramic camera was used for studying terrain for future drives.

Sol 646: The rover did untargeted remote sensing.

Sol 647: The plan for this sol is for Opportunity to check its composition and calibration target with the Moessbauer spectrometer, microscopic imager and alpha particle X-ray spectrometer. Also planned are observations of outcrop targets called "Show Low" and "Sedona" with the panoramic camera.

Sol 648 (Nov. 19, 2005): The plan is to conduct Moessbauer-spectrometer integration on the composition and calibration target, and to use the panoramic camera to observe an outcrop target called "Winslow" and a cobble target called "Snowflake."

Opportunity has driven a total of 6,446.45 meters (4.01 miles).

It's only right that Oppy get herself cleaned up a bit for Spirits birthsol party I suppose!

Hehe I knew it was too good to be true that I found something first, oh well, deserved a mention nonetheless....

A bit OT, but this is odd so I'll mention it...

We have the "Olympia" area, with Kalvrita, Antistasi and place names in Greece.

We are now a few meters south on a continuation of that outcrop and this area is physically separated from the "Mogollon" outcrop by sand drifts. But the current place names by Sol 647 (as suggested by the status report above) are Arizona place names.

It appears that, stratigraphically/lithologically, the Rover staff has placed Oppy in the Mogollon area. Which is significant to me because it means that these little changes we have been observing have added up.

But, OTOH it might be a simple matter of geography: Oppy is off that area on the north of the Erebus rim and on the area at the western rim of Erebus; I may be reading more into this than there is.

But here we are....
