Opportunity has been making good progress toward Endeavour crater with three drives in the past week.
On Sol 2274 (June 17, 2010), the rover completed over 60 meters (197 feet) driving due east. On Sol 2276 (June 19, 2010), the rover made a small J-turn to avoid a ripple and then headed 72 meters (236 feet) east.
With this drive, Opportunity has passed the distance for a half-marathon (21,097.5 meters, or 13 miles). The rover drove again on Sol 2279 (June 22, 2010), covering over 70 meters (230 feet) to the east/southeast.
As of Sol 2279 (June 22, 2010), solar array energy production has improved to 320 watt-hours, atmospheric opacity (Tau) was 0.257 and the solar array dust factor is 0.5585.
Total odometry is 21,209.69 meters (21.21 kilometers, or 13.18 miles).
