Checking on the MER Filenames Decoder (fantastic resource which everyone should have bookmarked, if only to prevent the embarrassment of "spotting" something "new" on an old image, like I've done in the past!: http://www.greuti.ch/oppy/html/filenames_ltst.htm ) that "dusty" image was taken on Tue May 18th. Today's Exploratorium images include shots taken on Sat May 22nd, which show a much clearer view...

Wow that IS clear. I think I can see smectite.

 When are we going to get this NASA "high resolution view" then, do you reckon? -------------------- |

QUOTE (ngunn @ May 26 2010, 09:55 AM)  What I don't know is the transverse baseline length between the two vantage points. From the sols for the two vantage points, you should be able to measure the baseline from Tesheiner's map. |

Probably after the new employees over at JPL finally get their desks organized and learn where the bathroom is. Then we'll start seeing some really nice image products. -------------------- If Occam had heard my theory, things would be very different now.

I'm sure Tim Parker will be doing that job, and he already knows where the bathroom is. But he may be tied up with MSL site mapping these days.

QUOTE (fredk @ May 26 2010, 03:36 PM) you should be able to measure the baseline Yes, since Stu has helpfully provided the missing link in the form of that great filename decoder I'll probably have a go. Is it safe to assume that pancams taken on driving days are taken at the end of the drive? Unfortunately exploratorium seems a bit intermittent - working this morning but not right now. EDIT: Estimating distances and angles from the map I think my calculation with the 50m baseline was about right. This would place the near horizon at 2500m or thereabouts, somewhere near the 1395 contour. That's about 20 m lower than we are now so we're looking down at it at an elevation angle of minus 0.4 degrees. If that's right Santa Maria will not come into view until we've travelled that 2500 m. Hopefully the lip of the Endeavour depression will be visible sooner. |

You can be sure by comparing with the local times that the ultimate hazcams were taken - those always follow the drive. You can also compare the site and drive numbers - they'll change after the drive. |

To complement CosmicRocker's gorgeous 3D view, I've stitched together a bunch of 1:1 IAS Viewer zoom views of the region of the Endeavour rim Oppy will be arriving at (I think?)...

What looks like large chunks of ejecta dug up by the small crater on the south end might make interesting targets.

Simulated HiRISE views of what we're all dearly hoping to see eventually... scale as accurate as I can make it...
Oppy approaching the foot of the hills...
And Oppy at the summit of the closest Faraway Hills...

Very nice Nirgal!
Have to be honest, my views aren't so much 'simulations' as 'messing about withs'

Thanks! That gave me an idea. I've taken your mosaic and have overlaid upon it the CRISM color map from the phyllosilicate paper I posted about earlier. I think it helps to see the CRISM mineralogical anomalies overlain on the high resolution image you provided. In this image ferromagnesian phyllosilicates (smectites) are shades of red and polyhydrated sulfates are shades of cyan.
Correction: I actually lifted the CRISM colors from the image that Emily posted on her blog. Her image was larger than the one in the pdf and it was not annotated. -------------------- ...Tom
