Well Opportunity is less than a two weeks from Mars. I'm really looking forward to seeing the difference in terrain between the two sites! The Panorama that JPL released tonight is fantastic!

Okay, I took a swipe at color correcting the photo you've posted to bring the four color keys more in-line with the photo you've shown that's supposed to be from the lander when it's here on Earth. I didn't nail the exact hues, but the colors are close enough.....so what's up with your point? Are you just saying that they're adding an extra dash of poetic license to the photos to make them Mars-ier or is there something else afoot that we should know about? Do tell!

True Colors of Mars

This image [below] taken on Mars by the panoramic camera on the Mars Exploration Rover Spirit shows the rover's color calibration target, also known as the MarsDial. The target's mirror and the shadows cast on it by the Sun help scientists determine the degree to which dusty martian skies alter the panoramic camera's perception of color. By adjusting for this effect, Mars can be seen in all its true colors.



part of the reason "blue" shifts to "pink" is that that particular shade of shows a strong spectral response in one specific filter wavelength outside our normal perceptual range (but which is valuable for scientific study)

Steve Squyres and Jim ( Pancam lead Scientist ) talked about this exact thing a few briefings ago.

Okay, so it's a possible coverup.

I see that Keith also has an interest in the Martian geological feature known as "the face". Even the hard sci-fi author Ben Bova was inclined to put relics on Mars and there are many archaeological sites here on Earth that could not be proven to be made by intelligent life if you were to have seen photographs of them from a satellite. Physical on-site investigation is the only way to prove it.

But. The odds are so incredibly against that feature being anything other than just that, a feature, I remain disinclined to believe that intelligent life has ever existed on Mars. I welcome the opportunity for someone to disprove me.

Then I want them to prove that it ever existed here.

Oh no!

They're reporting that the Gusev Crater is "blanketed in volcanic material" and that any evidence of sedimentary deposits were either scored away over the aeons or buried beneath volcanic emissions. They're trying to figure out if Spirit can hightail it off to the far away hills to get closer to potential sedimentary deposits.

Time for a road trip!

Good news for Europe and scientists everywhere!
The Mars Express satellite has been delivering fantastic images of the planet's surface!!


Dr John Murray, of the Open University, UK, who is on the camera team, told BBC News Online: "This is the first 3D camera sent to Mars.

"It is 10 times better than anything sent before. We have high hopes for it and how it will advance our understanding of Mars."

He added: "These first images are the culmination of more than 10 years of work. In a matter of minutes, we are able to map an area greater than Great Britain and Ireland showing details down to a few metres in diameter.

"At the end of the two-year mission, we will know the surface of Mars better than we do the Earth.

What are the sheeplike drones of local news reporters going to say when it turns out that the Mars Express mission WASN'T a "failure".

First Mars Express pictures

click for bigger versions

Picture taken by the High Resolution Stereo Camera (HRSC) onboard ESA's Mars Express orbiter on 14 January 2004. It shows an area 1057 miles (1,700 km) long and about 41 miles (65 km) wide that was captured by the HRSC as the satellite flew at an altitude of 171 miles (275 km).

Meanwhile, over in Gusev crater...

Spirit is heading for the target rocks "Adirondack", "Sushi" and "Sashimi" in the "Wasabi region"
and making donuts along the way



mmmm donuts...

Yeah, I started reading Robinson hardcore in school.

It doesn't even have to be colonization - when we establish a research outpost there, all of the same dynamics we go through here will crop up there.

Of course, with Robinson came Zubrin and that led to British conference on Mars habitation etc., etc. Heck! I had planned on using my thesis to investigate the architectural implications for a Mars habitat. I mean, from an architectural point of view, can we import our "rituals of living" to Mars and expect it to work? What kind of changes will we need to face to adapt to a martian environment? Talk about cabin fever, right? So many questions - structure, shelter, materials, psychology... Well. This post is a little OT from the rover mission, but the question you posed concerning Robinson reminded me of something that I haven't looked at in a long time and got all excited again!

okay... for those who don't like or dispute the photographic colours of Pancam

Today, Spirit returned the first spectrographic images of Gusev soil


Alpha Particle Xray Spectrometer

Quote:
This graph or spectrum taken by the alpha particle X-ray spectrometer onboard the Mars Exploration Rover Spirit shows the variety of elements present in the soil at the rover's landing site. In agreement with past missions to Mars, iron and silicon make up the majority of the martian soil. Sulfur and chlorine were also observed as expected. Trace elements detected for the first time include zinc and nickel. These latter observations demonstrate the power of the alpha particle X-ray spectrometer to pick up the signatures of elements too faint to be seen before. The alpha particle X-ray spectrometer uses alpha particles and X-rays to measure the presence and abundance of all major rock-forming elements except hydrogen.

Mossbauer

Quote:
This graph or spectrum captured by the Moessbauer spectrometer onboard the Mars Exploration Rover Spirit shows the presence of three different iron-bearing minerals in the soil at the rover's landing site. One of these minerals has been identified as olivine, a shiny green rock commonly found in lava on Earth. The other two have yet to be pinned down. Scientists were puzzled by the discovery of olivine because it implies the soil consists at least partially of ground up rocks that have not been weathered or chemically altered. The black line in this graph represents the original data; the three colored regions denote individual minerals and add up to equal the black line. The Moessbauer spectrometer uses two pieces of radioactive cobalt-57, each about the size of pencil erasers, to determine with a high degree of accuracy the composition and abundance of iron-bearing minerals in martian rocks and soil. It is located on the rover's instrument deployment device, or "arm."

It's alive, it has functioning power systems, some software capabilities, and some communications... but it seems to be bouncing all around the fault tree. They can't get the same error code out of it twice in a row, apparently. \

And, to boot, it refuses to downlink it's main telemetry which carries the debugging data. :P

So it's there, it's just in its own little personal spinning wheel of doom.

Bah! Better five Mars threads than five Bush treads.

I go straight to NPR now for all of my "get him out of office, NOW" news... Sure sure, we have all that "sour grapes" talk from the former Treasury official, but it's always more revealing than a web forum when you hear things like the founder of the modern EPA (a staunch Republican all his life), talk about what an incredibly deceitful bunch Bush and his cronies are.

Maybe I should stroll over to the Alien Conspiracy thread to find out if it was the worker-class Martian or the dirigible-class Martian that is holding Spirit for ransom!

Oh! Good news! They appear to have received a 20 minute burst of info from the Spirit rover! All isn't lost!

They were supposed to be drilling into Adirondack when the communications bobble occurred. Hopefully that data has been gathered!?

Also, they had a NASA spokesman on Letterman last night. Dave was really busting his chops about why we would need to send men to Mars. He had a series of photos of the Martian regolith snapped by Spirit...he took a look at one and said "I can tell you right now there ain't nothin' up there!". About five pictures later there was a suspicious looking item on the lefthand side...the camera zoomed in and it was an Applebee's that had been photoshopped into the picture.

Dave said "I guess I was wrong!"

Saw the briefing today. Despite the fact Spirit is behaving confused pentium it was awesom! They went through the actual data gathered during decent and how the "decenter" had compensated for thinner air and more vertical vind than expected. The above picture and the landers way through that picture was explained.

I say to hell with Mars! THe engineering complexity is much more interesting than a dead red rock.

Wow, it's continually rebooting itself...that's not good for the batteries especially if it's continuing that behavior throughout the night. The forensics team will, I suppose, be running tests on the Earthside version of the rover to narrow down what might be the cause of the bad behavior.

Wasn't there a solar flare during the trip? I'd be surprised if they DON'T discover if the problem was due to radiation, landing shock or inherent poor design.

We're not yet ready to send humans in 2004. In 18 years? Surely we must.



Edit: There are some new computer animations posted up on the JPL site that show Spirit's descent and bounce path - gathered by the sensors onboard. Would be a lot neater if the darned thing was working right now.

Ah the power of being a mod.

Please go to the first page and answer what I think is an importent question.

My take: For the same resources unmanned missions will give us much more information than manned missions. It doesn´t have to be rovers in every mission. It could be a platform lander that had a heavy duty drill that was able to look beneath the surface. It could be a ballon station that could send up ballons. The possibilities are huge and you won´t have to use billions to build huge space to transport a few humans there and back.
