Opportunity is now within 2 kilometers (1.2 miles) of the first landfall on the rim of Endeavour crater, at a place called "Spirit Point."
With multi-sol planning for the 4th of July holiday weekend, the rover drove only once in the past week with a drive to the southeast on Sol 2645 (July 3, 2011), of over 162 meters (531 feet). On Sol 2642 (June 30, 2011), the Alpha Particle X-ray Spectrometer (APXS) performed another atmospheric argon measurement. On the next sol, a forward link ultra-high frequency (UHF) test was conducted with the Mars Reconnaissance Orbiter.
As of Sol 2647 (July 5, 2011), solar array energy production was 421 watt-hours with an atmospheric opacity (Tau) of 1.03 and a solar array dust factor of 0.596.
Total odometry is 31,630.68 meters (31.63 kilometers, or 19.66 miles).
