However, the robotic arm experienced a stall in the shoulder elevation joint and stopped all further robotic arm activity. The sequenced APXS measurement on Sol 3140 (Nov. 23, 2012), then fortuitously became an atmospheric argon measurement. The joint stall had been experienced before with Opportunity when slow moves are commanded as in this instance. However, the engineering team did review all the associated telemetry and found no indication of any change in the health of the joint.</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; "><span style="letter-spacing: 0.0px">As a further step, a diagnostic move was included at the start of the plan on Sol 3144 (Nov. 27, 2012). That diagnostic showed a nominally functioning joint. The subsequent activity on Sol 3144 (Nov. 27, 2012), included a successful RAT brushing of the target followed by a MI mosaic and placement of the APXS. Also, over the last several sols, the rover has been collecting an extensive color panorama (Pancam), called the "Matijevic pan."</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; "><span style="letter-spacing: 0.0px">As of Sol 3145 (Nov. 28, 2012), the solar array energy production was 559 watt-hours with an atmospheric opacity (Tau) of 0.793 and a solar array dust factor of 0.608.</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; "><span style="letter-spacing: 0.0px">Total odometry is 22.01 miles (35,429.63 meters)."</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; color: rgb(4, 51, 255); "><span style="letter-spacing: 0.0px; color: #000000">Landing sites link - <a href="http://marsoweb.nas.nasa.gov/landingsites/"><span style="letter-spacing: 0px; ">http://marsoweb.nas.nasa.gov/landingsites/</span></a> </span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; "><span style="letter-spacing: 0.0px">Visit the Mars Exploration Rover page at</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; color: rgb(4, 51, 255); "><span style="letter-spacing: 0.0px; color: #000000"> <a href="http://marsrovers.jpl.nasa.gov/home/index.html"><span style="letter-spacing: 0px; ">http://marsrovers.jpl.nasa.gov/home/index.html</span></a>.</span></div><div style="margin: 0px; font-size: 12px; font-family: Arial; min-height: 14px; "><span style="letter-spacing: 0.0px"></span><br></div><div style="margin: 0px; font-size: 12px; font-family: Arial; "><span style="font-family: Helvetica; "></span></div></body></html>
