Opportunity has exceeded 30 kilometers (nearly 19 miles) of odometry! The rover spent the last few sols investigating some exposed rock outcrop en route to Endeavour crater, now just a few kilometers away.

On Sol 2608 (May 26, 2011), Opportunity bumped 60 centimeters (24 inches) to position the outcrop targets within reach of the robotic arm instruments. On Sol 2611 (May 29, 2011), the rover used the Microscopic Imager (MI) to collect an extensive mosaic of the exposed outcrop.

Opportunity then conducted a MI poker test, which exhibited anomalous behavior the last time it was used. The test indicated positive switch trip on just one of three tries. The project is investigating this further.

The Alpha Particle X-ray Spectrometer (APXS) was placed on the surface target, named Valdivia for a multi-sol integration. On Sol 2614 (June 1, 2011), Opportunity drove away with a 146-meter (479-foot) drive, crossing the 30 kilometer (18.64 mile) odometry mark.

As of Sol 2614 (June 1, 2011), solar array energy production was 408 watt-hours with an atmospheric opacity (Tau) of 0.860 and a solar array dust factor of 0.545.

Total odometry is 30,055.50 meters (30.06 kilometers, or 18.68 miles).

A Salute to the Spirit of Mars
Huntsville AL (SPX) Jun 06, 2011
The Voyagers are, perhaps, the best known example. Launched in the 1970s to explore the outer planets, the iconic spacecraft have zoomed far beyond their original targets to the edge of interstellar space itself, 9 billion miles from Earth and still making discoveries. Pioneer 10 and 11, Ulysses, Stardust-NEXT, Deep Impact, and others have similar track records. It has become almost routine for ... read more
