Opportunity Status at end of sol 44

On Opportunity's 44th sol, ending at 12:10 p.m. PST on Tuesday, March 9, the rock abrasion tool ground a 3.1 millimeter-deep (just over one-tenth of an inch) hole in the "Mojo 2" target on "Flatrock." Yesterday, diagnostic testing determined a voltage adjustment was necessary to overcome some mechanism "stickiness" in the routine during which the rock abrasion tool finds the highest point in the target area.

The routine worked perfectly on this grind with the new voltage setting. After one hour and five minutes of successful grinding, the rock abrasion tool grind motor stalled, probably while grinding into one of the spherules also known as "blueberries." These objects are known to obstruct the grinding tool and cause it to terminate its sequence.

Late in the martian morning, the Moessbauer spectrometer was placed on the hole, followed later by the alpha particle X-ray spectrometer. The miniature thermal emission spectrometer took two long atmospheric measurements. The panoramic camera was busy taking images of the hole as well as surrounding target areas.

The wake-up songs were "Try (Just a Little Bit Harder)" by Janis Joplin for the rock abrasion tool's second attempt at "Mojo 2," and "X-ray Eyes" by Kiss for the alpha particle X-ray spectrometer.
