A long strip image from the high-resolution camera on NASA's Mars Reconnaissance Orbiter shows the Curiosity rover's landing spot in Gale Crater, as well as the terrain leading south toward the mountain known as Aeolis Mons or Mount Sharp. The colors have been stretched to emphasize differences in surface composition. A dune field can be seen in deep shades of blue. Beyond the dunes, mesas and buttes are part of the terrain surrounding the 3-mile-high mountain.
Fresh imagery from NASA's Mars Reconnaissance Orbiter shows the newly arrived Curiosity rover sitting at its landing site in Gale Crater, as well as the sand dunes and rugged terrain that the rover must pass through to conduct its $2.5 billion science mission.
The dunes are painted in colorful shades of ultramarine, but those aren't the true colors: Most of the color images from the orbiter's High Resolution Imaging Science Experiment, or HiRISE, are color-coded to emphasize subtle differences in surface composition. The shades of blue are actually dusty shades of gray to the human eye. The area around the rover itself has a blue tinge because of the dust that was disturbed during Curiosity's rocket-powered sky-crane landing on Aug. 5.
Even some of the pictures sent back from the surface by Curiosity have been brightened up to reflect Earthlike lighting conditions, said HiRISE's principal investigator, Alfred McEwen of the University of Arizona. Pictures from Mars look "blander" because the sunlight has to filter through red Martian dust in the atmosphere, he said. Many of the processed pictures from Curiosity's mission are being provided in both "true color" (Marslike) and "white-balanced" (Earthlike) versions.
Curiosity's primary mission is due to last one Martian year, or almost two Earth years, and the rover might need the first half of that mission to make its way south through the dunes. A picture from Curiosity's vantage point shows the dunes as a dark streak in the distance.
"We need to get to the clays which are just beyond that dune field that you see, and then up into the sulfate-bearing rocks which tend to form these buttes and mesas," said Ashwin Vasavada, deputy project scientist. "You're seeing really the scientific mission before you here."
Vasavada said it's about 5 miles (8 kilometers) as the crow flies between the rover and its science targets at the base of a 3-mile-high mountain (5-kilometer-high) known as Aeolis Mons or Mount Sharp. McEwen said there's roughly 4 miles (6.5 kilometers) between the rover and the bottom edge of the orbital image, which was taken six days after Curiosity's landing from an altitude of about 168 miles (270 kilometers).
The rover is designed to analyze rocks and soil for the chemical signatures of potential habitability — using a laser zapper, an X-ray beam, a drill, an onboard laboratory and other high-tech gear. Curiosity is still going through its post-landing checkouts, but the show could start going on the road in a week or so.

We're the aliens you know. Building our flying saucers, sending our probes to explore other planets, broadcasting our presence into the sky.
This is only the beginning. Our earth is an oasis, a safe place to begin our journey. But these little planets and moons in our solar system... they're our first baby steps into a much larger world, full of wonders we cannot imagine.
Not the first batch of them though - earth is full of evidence of ancient civilizations who may have had advanced technology. We need to figure out what destroyed them, so we have a backup plan to not to become extinct :)
Cool pics...... Looking at the picture gives me a uncontrollable urge to play in Martian sand.... My CURIOSITY is killing me. (snicker)
Science is taking us everywhere. Thanks NASA, thanks Alan, and thanks Curiosity.
I hope we find unmistakable evidence of past life. This is one helluva scientific achievement, kind of like hitting a golf ball in New York and landing a hole-in-one in Bangkok.
Go Science!
amazing stuff. go get 'em NASA
That's a helluva picture Alan. Thanks for another great article.
Did anyone else notice the worm tracks?
Trust me.
There will be worms. (and great pics Alan)
Who are we kidding, Alan? We all know that you took your Nikon camera and aimed it down on your psychadelic ceramic tiles in your Man Cave to take that pic...I saw the same design over at Home Depot; special order only, eh? I could take a match stick to my floor too and get the same effect as where Curiosity 'landed'... LOL!
:-)
PS: Amazing pics and thanks for sharing, Alan...Cheers!
Almost the neatest thing since the invention of the Vagina and only 6 posts. I'd love to have been involved or at least a shuttle flight.
True color or not, that is a beautiful picture. It would be cool to have that printed out in high quality and on gloss paper about 6 feet tall to hang on the wall.

In every Space SciFi movie, the laser designed for geology, is always the weapon of last resort to kill the alien that has already eaten all but the last crewman.
I think I scored a hole in one.
Let's nuke it from orbit, just to be sure.
Asta LaVista, baby.
I wonder if they were able to take a picture that included the sky crane crash site?
There's a picture showing that site that came out a few days ago:
http://hirise.lpl.arizona.edu/images/2012/details/cut/sky_crane.jpg
You can see chunks...
@ Alan We've been trying to find out how "smart" the electronics were on the sky crane here at work. While the two main Power PC 650 computers are on Curiosity, were there any "brains" on the sky crane? Unfortunately, we are now looking at the only off-earth superfund site with 300 lbs of Hydrazine sublimating. Was there any way to program the sky crane to touch down softly instead of just veering off and crashing? Since it hovered, I would think it could have taken a shot at a soft touchdown. Any info on this would be greatly appreciated.
What happens when Curiosity gets stuck in the dunes?
That is definitely something they don't want to do. The mission managers have said multiple times that they'll be able to find their way through the dunes. Hope they're right.
i hope somebody paid up their aaa card?
it goes to show what our scientist can do.and what our people can build.
who says space exploration does not pay off? here is proof of what can be achieved and used here on earth.
what a show nasa.
"Turn left... in... 200 yards. Recalculating....."
Cool picture of a dot NASA.
Maybe you should invent a camera and/or lens that will take better images AND be lightweight and energy efficient enough to travel on a spacecraft.
I wonder what the feathery, arc-like structures, are - the ones splayed hand-like just 'up-picture' from the beginning of the blue dune field - especially the three or four neat little ones located just 'up-picture' from the 'blue finger' that prijects 'up-picture' from the right side of the dune field, and just to the left of those hydro-thermal looking features at the fingers tip.
The larger ones seem to be burried and to have been 'exposed' - while the three newer (if I may) looking ones by the (geysers?) seem to be 'on top' of the sediments covering the others, eh?
Hmmm.....Newsflash, August (??)th, 2012, Sol (?? ?, even) NASA Curiosity Rover finds Petrified Martian Fungus?
I believe they are worm tunnels.
I use to read all the biographies of famous explorers. They captured my imagine with their fearlessness of the unknown. Can't believe I'm now rooting for a robot explorer.
We take what we can get, right? I too wish it was humans up there but at least we have something up there doing the research. Someday that first man on Mars will be a household name.
imo, NASA needs to be defunded. This mission will accomplish nothing new.
I see. What are your science credentials, Ken?
@VetInVA None. Don't feed the troll......
I bet it will accomplish more than you will ever accomplish, Ken. Just my opinion.
Good thing our founders didn't have that attitude or your name "ken1776" would need to change.
Wow...just wow. Just landing there was a major accomplishment. Everything else is gravy.

Earth Is The True Planet Of War, Not Mars (Curiosity Rover)

I'm a little confused as to why Mars/Earth colors are necessary. Why not just show us as it is?
Well, I know with distant objects, like Pluto or the moons of Saturn, there simply isn't enough light. The Sun is really far away, barely more than a slightly larger and brighter star. So if you saw the pictures "as it were if you were there, looking out the transparent, untinted window of your spaceship" the scene would be very, very dim.
I'm not sure about Mars, though. What would it look like to a naked human eye, if we could arrange such a thing? What exactly are the true colors of Mars? Does the atmosphere change the default light away from what we're used to? How much smaller and dimmer IS the Sun at that distance?
#18
Excellent point, colour is what is reflected and what the atmospheric gases allow to reach out retinas, so in reality, when the gas mixtures differ from those that we are used to, so does the colour palate, so nice question, the answer I would assume, :-) not ( Arse U me) if you do not mind, is that most people might not be aware of that scientific fact, and so it " makes life easier for them ";-)
I remember a story about the first Mars landing (can't seem to find it on the internet). The lander had only a black and white camera and used filters to send back three images. The images were then combined to give a color image of what the lander was seeing. The first color image they created had a red sky. So they adjusted the balance of the three images until the sky was blue. I wasn't until they had printed a bunch of copies that someone noticed the stripes on the flag that was visible in the image were blue instead of red.
I've seen the final image with true colors and a nice rosy red colored sky and a nice red white and blue flag in the bottom of the image. I heard the designer of the lander put the flag in that location so they would have a definite color palate to balance the images with.
If you want to see an example of Earth light verses Mars light, take an object and view it under a non-color adjusted light bulb (most lights you buy for your home are color adjusted to give a warmer feeling). Then take the object and look at it outside on a bright sunny day. Or the same object on a sunny verses a cloudy day. Do they look different? Different light sources (and Earth atmosphere verses Mars atmosphere give different light sources) make the color of objects appear different.
I think the main reason they change the colors is to enhance very small differences in real color. In real life, the color changes are very subtle, but it can make the difference between sandy and rocky terrain. By digitally enhancing these different colors, it is easier to see the differences and therefore you can make better decisions about where to go or what to focus on. The object of the rover is not to send pretty pictures, but to send detailed pictures that can enhance what we know about the planet.
Thanks for the helpful answers, all! I'm going to see if I can find any of those pictures of the discolored flag. All of this is so fascinating!
Thanks Alan!
YUP! Thats DUNE BUGGY Territory!
Don't Like the Blue! Makes it Look Like BLUE LAGOON Water!
There: the Lonely Mountain.
"It seemed as if darkness flowed out like a vapour from the hole in the mountain-side, and deep darkness in which nothing could be seen lay before their eyes, a yawning mouth leading in and down."
I wonder why they didn't land closer to their target site?
After how many MILLIONS of miles, you want to know why they couldn't get CLOSER??? Sure, YOU try throwing a basketball at a hoop from 5 miles away and get nothing but net.
Besides, this provided an optimal landing site. They didn't want to risk setting down in the dunes farther south or on the rocky slope of the mountain even further south. Realistically, this site was the best option.
The article states that it is a two year mission and the first half will be spent driving to their target location.
Getting there is half the fun.

Its Speed/distance/day is about a " football field " so 6Kms is a long distance.
The biggest impediment is " power " and without the PV power 110watts a day is not much at all.
That's 110 W per hour = 2600 W-hr per day. That is fed to the rechargeable Li batteries, which are then used for the electrical needs of the Rover. The MER rovers had a maximum of about 900 W-hr and survived on less than 200 on some periods.
Another artice on the Slate said that Curiosity runs on plutonium from a Soviet-era nuclear weapons plant.
This accomplishment is remarkable. Hopefully it inspires a new generation of explorers and scientists.
the quertion . was there life on Mars? NO. never was suitable in the first place.
#23.5
Thank you, I should have stated watts/Hour, the actually useful watts are actually 2080 taking losses into account, and both spirit and opportunity have an RTG. Their PV power was and hence what was said earlier more " efficient " and hence " if it is not broken do not fix it " eight years reliable PV power is " not broken "
