OPP-SOL512-1P173635127EFF55XKP2429L2M1.jpgA boundless sea of dunes...On the way to Erebus (4) - Sol 51258 visiteD'altro canto, se Opportunity riuscisse nell'opera di attraversare questa trappola sabbiosa (sand-trap, come definita dalla NASA stessa) che è diventato il deserto di Meridiani Planum, allora l'insabbiamento di 5/6 settimane nella Duna Purgatorio diventerebbe, a nostro modo di vedere, completamente assurdo (tecnicamente) ed ingiustificabile (nella durata).
E' solo una questione di logica e di coerenza, secondo noi: quella logica e quella coerenza che, purtroppo, stiamo vedendo - nel quadro di questa Missione - sempre di meno.

Spirit è fermo?

OPP-SOL528-1P175057662EFF5702P2439R2M1.jpgErebus Highway (2) - Sol 52958 visite"...But there's a catch: the entrance to the Erebus Highway is not straight South of us, along the troughs. It's a bit off to the East, on a heading closer to approx. 160°. That means that in order to get to it, we'd have to head off cross-country, going up and over quite a few ripple crests. That's do-able, but it's also a lot slower than just bombing straight South down a nice trough.
So: If we do head for the Highway, we make slow progress for awhile, but maybe we get to a better route to Erebus Crater. If we head down the troughs instead, they take us at a pretty decent speed directly to... Erebus Crater!
So it should work either way. We're planning the weekend drive as I type this, and after a bit of discussion we've decided to stay for now in this nice wide trough that we've found and try to get as much southward distance within it as we can. Whether or not we're actually going to "hit the Highway" is an open question at this point, but Erebus isn't too far off either way you cut it..."

OPP-SOL536-1F175770658EFF57KRP1214L0M1.jpgPanorama - Sol 536 (1)58 visiteCaption NASA originale:"The Opportunity Team's current strategy for driving alternates segments of using visual odometry to check for slippage with segments of blind driving for less than 5 mt (about 16 feet).
The strategy and hard work designing and commanding drives through troughs between ripples contributed to the Rover making 89 mt (about 292 feet) of progress over three drive plans.
Rocks and cobbles have begun appearing in images of Opportunity's new surroundings, for the first time in many weeks of traversing through rippled terrain".
