Wow, that shot really gives a sense of the terrain. Notice how the amount of haze increases with distance, as on Earth (but unlike the Moon).

Wow indeed! :lol: That has to be one of the most impressive views we've seen from the rovers to date. Any idea how big those dust devils are?

wish I could paint...that scene with the dust devils would make an incredible painting

At unmannedspaceflight somebody estimated it 197 meters wide and at least 750 meters tall. It seems to be at a distance of 4.7 km. Both DD's also feature impressive shadows.

Robot From Earth Climbs Mountain On Mars (http://www.spacedaily.com/news/mars-mers-05zzzp.html)


428 sols after reaching the foot of the Columbia Hills and 582 sols after landing, Mars Exploration Rover 'Spirit' has finally arrived atop Husband Hill - some 90 metres above the basaltic floor of Gusev Crater.

Best picture of Mars yet. Ansel, eat your heart out.

All,
Has Spirit made it to the summit?
All the raw image pics from sol 583 seem to show horizon all around!

Is this the first ever ground-level view of a Martian dust devil?

BTW, I only get an empty pic from the link in the OP.

Yes, it's almost there.

No, Spirit has got many views of dust devils. This one is one of the largest seen so far.

See this (http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20050819a.html) and this (http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20050708a.html) page. There are several dust devil movies taken by Spirit.

Spirit finishes mountain marathon (http://www.nature.com/news/2005/050822/full/050822-3.html)


After a long uphill hike, there's no better reward than the view from the summit. So it is understandable that the operators behind the Mars rover Spirit had their robot pause to survey the terrain after it reached the top of Husband Hill, even if the area does look remarkably similar to the area from which the rover just came.

"It's a beautiful view," says Ray Arvidson, a geologist from Washington University in St Louis, Missouri, and second-in-command of the rover science team.

No, Kullat Nunu, it WAS there.

See the Nature link from ToSeek, "Spirit has been exploring the red planet for 582 martian days, or sols, and the rover just keeps on keeping on." 582! So it WAS on the summit on sol 583!!!
YeeeeeeeHA!
Am I the first member of the public to recognise that!

Gloat!

WELL DONE SPIRIT!

Strangely, the Rover site has nothing at all about it!

One thing that might be different is that there might be cinder cones or even a maar on this side of the hills. See the images linked here:

According to this glossary cinder cones don't involve interaction with water:

Volcanic and Geologic Terms.
http://volcano.und.nodak.edu/vwdocs/glossary.html

If the flat area is indeed a maar then perhaps the nearby cones are tuff cones which like maars are created through volcanic water interaction:

Another sol (day) for rovers on Mars (http://www.nj.com/news/ledger/index.ssf?/base/news-2/1125037550191370.xml&coll=1)


They move slowly and take naps. Their camera lenses are mottled by dust, their wheels sometimes gimpy.

Remember the Mars rovers? After a year and a half on the red planet, Spirit and Opportunity are still puttering along, poking at rocks that tell the story of the planet's warm and watery ancient environment.

On Sunday, Spirit crawled backward to the top of 300-foot-tall Husband Hill -- the highest any rover has been -- ending a climb that took more than a year. Today, the rover is set to finish a panoramic picture, which NASA plans to release next week.

Good links there Bob, cheers! Certainly a tuff ring looks very like what 'home plate' looks like.

That's great. I saved it, and may use it as a desktop wallpaper.

How did NASA fake that one? Just kidding! I thought I was on a woo-woo forum for a moment.

Spooky moment!

Went to the raw images page from Spirit to see what was new. Scanned down the nearly 250 pics from Sol 586. http://marsrovers.jpl.nasa.gov/gallery/all/spirit_p586.html
Just over half way down - WHOA! WHAT's THAT?? FOOTPRINTS???

No, of course they aren't. Look at the pic itself: http://marsrovers.jpl.nasa.gov/gallery/all/2/p/586/2P178390930EDNAE03P2276L4M1.HTML

But the tracks do look like moonboot prints, don't they? J.

Spirit Samples Husband Hill (http://skyandtelescope.com/news/article_1586_1.asp)


For much of its nearly two-year mission, NASA's Mars Exploration Rover Spirit has been the forgotten child. Its twin, Opportunity, was the first to find geological layering and evidence for past liquid water, and its landing site is covered by diverse rocks and soils. But for many months, whenever Spirit sampled a rock, it always sniffed the same thing volcanic basalt. The floor of Gusev Crater, Spirit's home, was uniform in composition and, put bluntly, somewhat boring.
