Great articles, as usual, Stu.
Just a correction to the second picture, that one with the distances to all little craters up to the "Waypoint": it's about 270m (and not 1.7km) to that crater.


Ah *****! Corrected, thanks. That's what you get for getting up at 6am to catch up on stuff before going to work... smile.gif

I know we won't be approaching Santa Maria from the south, but I'm struck by some features there... are the "domes" filled-in, older craters? Wind-carved features? They just caught my eye, that's all...

My impression is that we can basically see all of the plains now, up to the near rim of Endeavour.


fredk, looking at that second image of yours...and to think that Endeavour was just a crazy thought some time ago still boggles my mind... smile.gif

Just for fun, a pic showing the relative sizes of Santa Maria and Victoria Crater...

Nice comparison Stu. So Santa Maria is kind of Duck Bay sized, that helps me visualise it a lot, thanks.

The new navcams and pancams are down. Here's a stereo view showing a number of the craters ahead on the plains. In order of distance, the closest is what I labelled D (the "doublet"), then C, then A (the "waypoint"), and finally much farther away is G. Immediately past D is the ultra-flat stretch.

(Oh yeah, and even farther away is a little crater known as Endeavour...)

Nice graphic, Stu. How would you feel about tossing Endurance in there for comparison? smile.gif

Interesting comparison, it looks like santa maria crater is large enough/old enough for the 'capes' and 'bays' formations to form. If that were the case for santa maria then it would indicate that the original crater was smaller than the size we see now.

It would be really interesting to see all the craters above the size of say eagle crater size in Oppys vicinity/on meridiani planum, against each other, a bit like Emily's asteroid montage. It would even be neat to keep the positional relationship to see morphological differences in cratering relating to changes in the plains in which they are punched.

if there is a size correlations with bay formation/depth that would be interesting to see. It might also give some clues as to the erosion rate as larger craters would be expected to be older.

Actually the fabulous stretched pan was from Phil - I only added the labels.

sorry Phil! Thanks to everyone who lets me use their pix on my blog. Much appreciated.

Might try to make an 'all craters' montage, when I'm not so busy. Maybe Christmas. 2030! smile.gif

Here it is!

I put famous craters in one picture, grabbed from Google Earth (also grabbed the strange color of endurance). It roughly the same scale, but not really exact.
The point inside the eagle crater is the lander. The rovers are about the same size (3-4 pixels).

I put also the next waypoints to the picture: Santa Maria and Cape York. Interesting: Cape York could fit into Victoria!
Santa Maria crater is a little smaller than endurance, but Bonneville, visited by Spirit, is larger.

The Home Plate, well visited by Spirit, is just as big as Santa Maria.

Thanks MoreInput!

Funny, I thought Cape York was much much bigger...

Another really fascinating monthly report by A.J.S. Ryal (with help from Stu and Tesh amongst others) has just been released on The Planetary Society website for October, 2010.

Others will be able to post a link and give a far better synopsis than I but it really does provide a lot of detailed information for the MER fan and scientist alike!

Basically, the excitement level with both rovers is growing - Spirit in anticipation of her regaining contact, Opportunity with Santa Maria and the continuation of the journey to Endeavour.

Thanks again to all those who keep us so well informed and up to date with these missions.

Neil

Here's our first navcam view of the new terrain:
