You're right Tesheiner... rolleyes.gif

EDITED: Where is "94 days delay included" it should be read "119 days...", it makes all the difference... wink.gif

Well, it's not an artifact created by GE because this discontinuity is also visible in the map projected JPEG2000 images.
I have two guesses:
1. Something in the map projection software
2. It's a boundary between two CCDs in HiRISE.

Here's a similar artifact near the same area but on a different picture.

Yes, a seam between two CCDs. This is quite common in HiRISE images.

According to this latest map from Ustrax, it's now clear why Oppy made that little "wrong-way" drive on sol 1820: she tried to keep to Ustrax's proposed path! laugh.gif

It also explains the elevated currents in the RF wheel.
She was trying to turn right, but they wouldn't let her wink.gif

Regarding the 1860 driver. There are no images for the end of the 1859 or 1860 drives at either the rover home or exploratorium sites. Was the 1860 drive planned based on the 1857 data? Can the rovers be driven blind for a second sol (without fresh navcam and/or pancam images) using the current software? I'm reading Scott's Mars and Me, at at the begining of the mission I think you couldn't. Possibly images our down, but just not available to us. Can Paolo, or anyone answer my questions.

On the raw image pages. There are, however, images on the ground, that the team can see. Probably just one of those 'give the server a kick' moments that happens from time to time in the raw JPG pipeline.

Roving, roving, roving... smile.gif

90+ meters were added to the odometer this sol (1863) and we've covered almost half of Porcupine's diameter. Not really crossing but just bordering the crater (or its remains 'cause I can't really see it on the navcams).
Check the route map in a few minutes...

And I think it will improve in a few hundred meters. We are approaching an area which looks it has smaller ripples so we may see longer drives, imo.
