(contracted; show full)unity attempted to grind a shallow hole into a target called "Flat Rock" during its 42nd sol on Mars, ending at 10:51 a.m. Sunday, PST. However, the operation of the rover's rock abrasion tool produced almost no discernable impression on the rock. All indications are that the tool is healthy. Controllers plan to run some diagnostic tests during sol 43 (ending at 11:31 a.m. Monday, PST) to aid with tuning parameters for a second grinding attempt on the target on sol 44.

Opportunity observed 
a grazing [[astronomical transit|transit]] of Phobos across the Sun with its panoramic camera on sol 42 as a practice run for future imaging of Mars' moon [[Phobos]] passing in front of the Suna better transit observation opportunity on sol 45 (see [[Transit of Phobos from Mars]]). The alpha particle X-ray spectrometer was placed against "Flat Rock" for an overnight reading to identify the chemical elements present.

Wake-up song for the sol was "Break on Through (to the Other Side)," by [[The Doors]].
