Opportunity Under One Mile from Crater Rim

Opportunity has exceeded 32 kilometers (nearly 20 miles) of distance on Mars and is now less than 1.5 kilometers (approximately a mile) from the first landfall on the rim of Endeavour crater.

On Sol 2649 (July 7, 2011), the rover drove over 141 meters (463 feet) to the southeast. Available energy permitted Opportunity to wake very early for an ultra-high frequency (UHF) relay pass to return extra data to Earth.

On Sol 2651 (July 9, 2011), an atmospheric argon measurement was performed with the Alpha Particle X-ray Spectrometer (APXS).

Also on that sol, a test of trying to warm the rover's electronics to mitigate clock drift was performed by keeping the rover awake longer. On the next sol, the rover drove over 150 meters (492 feet), continuing in the roughly southeast direction towards "Spirit Point" on the rim of Endeavour.

Then on Sol 2654 (July 12, 2011), Opportunity drove 80 meters (262 feet) to the southeast, crossing the 32 kilometer (nearly 20-mile) odometry mark.

As of Sol 2655 (July 13, 2011), solar array energy production was 435 watt-hours with an atmospheric opacity (Tau) of 0.996 and a solar array dust factor of 0.596.

Total odometry is 32,003.14 meters (32 kilometers, or 19.89 miles).

Mars Opportunity Rover Nears Endeavour Crater Rim
Pasadena CA (JPL) Jul 15, 2011
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 Spectr ... read more
