MARS: S putovanja rovera OPPORTUNITY

U gornjem dijelu, desno, se vidi sjeverni dio, ustvari sjeveroistočni, "otoka" Cape York, po kojem se oppy šetala više od godinu dana.

Daleko na jugu, udaljeno0st cca 25 km, vidi se izbačeni materijal (rub) kratera "Iazu".
Promjer (po sjećanju) cca 8-9 km.

sols 3657-3662, May 08, 2014-May 13, 2014: Opportunity Explores Region of Aluminum Clay Minerals

Opportunity is exploring south of 'Solander Point' on the west rim of Endeavour Crater. The rover is exploring the region of aluminum-hydroxyl clay minerals seen from orbit.

On Sol 3657 (May 8, 2014), Opportunity collected a Microscopic Imager (MI) mosaic of the surface outcrop, called 'Ash Meadows,' then placed the Alpha Particle X-ray Spectrometer (APXS) for a multi-sol integration. On Sol 3659 (May 10, 2014), the rover drove just under 85 feet (26 meters) to the east, approaching a region of extended outcrop as a possible site for clay minerals. Also, Opportunity tested the new two-second spacecraft clock correction sequence. Over the next two sols, the rover collected an atmospheric argon measurement with the APXS and performed two more one-second-clock corrections.

On Sol 3662 (May 13, 2014), Opportunity bumped 7 feet (2 meters) forward to approach an exposed rock outcrop for further in-situ (contact) investigation.

As of Sol 3662, the solar array energy production was 761 watt-hours with an atmospheric opacity (Tau) of 0.621, and an improved solar array dust factor of 0.964. Perfectly clean solar arrays would have a dust factor of 1.0, so the larger the dust factor, the cleaner the arrays.

Total odometry is 24.49 miles (39.41 kilometers).

Dust factor 0.964, je samo malenkost manje od tvorničkog. Ovdje su "pijavice"  temeljito čišstile solarne ploče. Tau = 0.621 znači solidnu vidljivost, zato i imamo proizvodnju električe energije od 761 watt-sati. Ovakve proizvodnje nije bilo još od vremena spuštanja na Mars. Dobre prognoze za dugi život ove stare i dobro očuvane dame.  

wow...

sol 3671....brušenje......Nigdje prašine na instrumentima, sve izglancano.
