Opportunity is making her way towards the first science waypoint of the new extended mission on the rim of Endeavour Crater.
The first waypoint is a feature named 'Spirit Mound,' one of the locations visited by the Corps of Discovery 200 years ago.
The rover has been driving due east and collecting both Panoramic Camera (Pancam) and Navigation Camera (Navcam) panoramas along the way, both to document the terrain and to provide drive-direction paths.
On Sols 4495, 4497 and 4500 (Sept. 15, Sept. 17 and Sept. 20, 2016), Opportunity drove 159 feet, 91 feet and 88 feet (48.35 meters, 27.71 meters and 26.95 meters), respectively.
All of the driving has been down slope and some forward slippages has been apparent.
As of Sol 4500 (Sept. 20, 2016), the solar array energy production is 520 watt-hours with an elevated atmospheric opacity (Tau) of 0.845 and a solar array dust factor of 0.693.
Total odometry is 26.99 miles (43.43 kilometers).
