OPPORTUNITY UPDATE: Diggin' into 'Tennessee' - sol 138-140, 
June 18, 2004

Opportunity spent sol 138 grinding an 8.12-millimeter (0.32 inch) 
hole into the rock target called "Tennessee." It took the rover 
2 hours and 4 minutes to complete this grind, which is the deepest 
yet of the mission. After all this hard work, the rover went into 
a deep sleep for the night.

On sol 139, Opportunity used the microscopic imager to analyze the 
hole in Tennessee. The rover also performed both a daytime 
Mossbauer spectrometer observation and an overnight alpha particle 
X-ray spectrometer integration on the abraded surface.

Opportunity was busy finishing up some miniature thermal emission 
spectrometer observations of Tennessee on sol 140 and then began a 
long Mossbauer integration that ran for the entire sol. Opportunity 
enjoyed some more deep sleep after these activities and will finish 
up the last of the Tennessee observations the morning of sol 141.
