Probe Captures Avalanche on Mars

mdekato writes "MSNBC reports that NASA's Mars Reconnaissance Orbiter has captured an avalanche on Mars' surface as it happened. Very good still images show what must have been an awesome sight. 'The full image reveals features as small as a desk in a strip of terrain 3.7 miles (6 kilometers) wide and more than 10 times that long, at 84 degrees north latitude. Reddish layers known to be rich in water ice make up the face of a steep slope more than 2,300 feet (700 meters) tall, running the length of the image. Mars' north pole is covered by a cap of ice, and it even snows there. The scientists suspect that more ice than dust probably makes up the material that fell from the upper portion of the scarp.'"

That's what they get for straying off the marked path.

Why they never made Skiwatch

[jollyreaper]

Baywatch was a very popular show. It would seem to follow that Skiwatch would also be very popular. You're talking about athletic, fit people doing marvelous adventuresome things. Then I realized the problem: it's hard to show sufficient skin to entice the reptile brain audience when that would only lead to frostbite. A babe in a parka looks like a hunk in a parka looks like an IT nerd in a parka -- nobody could tell the difference. Skiwatch would never succeed. If that's the case, Martian Skiwatch would be

Why not? There are plenty of proposals for skintight [wikipedia.org] suits.

The only problem is the helmets, but I'm sure that can be addressed with a 360 degree glass bubble.

Sorry about the avalanche. I accidentally started the reactor. It was just so tempting to put my hand in the alien handprint.

As small as a what?

I know that we've sent various missions to mars; rovers, probes, environmental impact [wikipedia.org] among other what-have-you; but, and this, I feel is important, when did we send the office furniture?

My question is, if there's an avalanche on Mars, does it make any noise? If so, what color?

Re:

NASA, as part of the government, is bureaucratic by nature. Everything must be supervised by some guy behind a desk. It's considered a hardship post, but ever since the first Viking lander, someone has been on Mars to supervise the government work going on. And of course he has to have a desk.

In true bureaucratic style, the supervision must be supervised from even farther away. Thus the camera systems searching Mars. Well, they may find the desk, but they'll still have trouble spotting the dude himself

In Martian News Today

[Hoi Polloi]

"A skier died in an avalanche today while attempting a decent of the dangerous Xplplplt Cliffs near the North Pole. Search and rescue teams found the victim's body which suffered 8 broken limbs, damage to 2 heads, and 1 missing attenna. The victim did not appear to be wearing a teleporter as recommended for skiing in the backcountry."

He would have been OK, except

It's not that much of surprise when you think about it. It is, after all, the only logical progression for outsourcing; who's better for IT support? Some random guy or a spaceman? Soon, despite the cool, we'll be relieved that the help line's only over in Bangalore...

And a spy satellite looking at us would see how much then? Can they look into office buildings? What about a camera in a building 10 blocks away?

The original link, with many more stunning shots

[sighted]

The original story from NASA [nasa.gov] contains some fascinating additional details, a beautiful picture of the Earth and the Moon taken from Mars orbit, and links to thousands of other Mars Reconnaissance Orbiter images that were also released yesterday.

Re:The original link, with many more stunning shot

[AndGodSed]

That picture of Earth is awesome. I guess we are no longer a "Lonely Planet"... still small in the bigger scheme of things though...

Re:The original link, with many more stunning shot

[ittybad]

Wait a second! Wait one gosh darn, cotton pickin' second. I have a question: This may be ignorance speaking, so I hope someone can shed some light on the subject. If you check out the image of Earth and our Moon, why do we not see stars? Where did they go?

Re:

[sighted]

It's a question of exposure levels. Go out and take a picture of the full moon. If you have exposed the moon correctly, you won't see any stars around it, either. Its light will have washed them all out. Same deal here.

Re:

[Ihlosi]

If you check out the image of Earth and our Moon, why do we not see stars? Where did they go?

They went to the same place that they go to during the day. Hey, I don't know where that is, but I don't see any stars when the sun is shining, so they must have gone somewhere, right ?

Well, you know the old saying.....

"It's great to see something so dynamic on Mars. A lot of what we see there hasn't changed for millions of years."

Mars has dust storms quite often, with some covering the entire planet. How would this have not changed anything during millions of years?

Re:

[Aegis Runestone]

True, but we've never witnessed an avalanche on Mars before. Now that's pretty cool (no pun intended). This does not, however, necessarily show that the planet is active. As far as plate tectonics on Mars go--it's dead. :/

Re:

[iamlucky13]

Well first of all, he obviously said "A lot" hasn't changed, not all. The dust storms don't result in noticable changes to anything from a reasonable distance, certainly not from space. The recent storm that cut into the rovers solar power deposited a layer of dust not even thick enough to be opaque (fortunately), and for any natural objects, it's just dust that was already on them anyways. The dust is ultra-fine grit; nothing that catches the eye by itself.

The polar CO2 icecaps come and go with the seas

Re:

[pipatron]

The dust is ultra-fine grit

Grits in an avalanche... I guess it's not very hot grits then?

You aren't getting it

[dreamchaser]

Most of the Martian terrain has apparantly been static for up to millions of years. Dust storms are one thing; we know there is a dynamic atmosphere with seasons and weather there. Capturing an actual avalance, where the surface features are moving and changing, is another matter entirely.

Global Warming or Al-Quida???

[choochb71]

So...did Mars global warming cause this (Democrats) or is it some kind of Al-Quida plan to keep us from Mars (Republicans)? I think it was Ralph Nader.

Re:

[truthful cynic]

The upper, steepest section, which appears highly fractured due to blocks pulling away from the wall, is the likely source zone for the falls. The precise trigger mechanism is not yet known, although the disappearance of the carbon dioxide frost

Isn't it obvious by the loss of frost? Damn oil companies are ruining Mars already.

Re:

[Ihlosi]

More like increases in solar energy. Wouldn't that be a hoot, disproving the global warming idiots by using a whole other planet as evidence.

You'd still have to explain why the other seven^H^H^H^H^Hsix planets (and the dozens of moons) in our solar system are unaffected by the assumed increase in solar power output.

Re:

[truthful cynic]

If you really want to have a a /serious/ thought discussion on this, consider the following:

1) Nothing much can be said about objects with not much atmosphere, since the only observable outcome would be the temperature of the body which would just fluctuate due to radiational cooling since there's no atmosphere to keep any excess heat in. This would eliminate Mercury and most of the moons.

2) Thinking there will be any measureable outcome from single digit changes from an object that appears as a tiny

[wizardforce]

speaking of "avalanches" of dust and rock, the image that was thought to indicate present day water movement on mars may actually be the result of one of these dust avalanches instead.

Re:

[Foo2rama]

I do not think this was a dust avalanche. If you look at the pictures you see the snow line above, and that line looks pretty broken up, that tied with the number of these caught on film makes it look like a fairly common occurrence. So yes this is water movement, but a landslide/avalanche does not leave the same footprint as water based geological weathering. For example water would not leave a talus field.

Why they always gotta be outdoing earth?

[philspear]

They never do anything small on mars, do they? They have that red dot that's apperantly something like 1000 times worse than any earth hurricane ever, they have two moons as opposed to our one. And now this 60 kilometer long avalanche visible from orbit. It wouldn't suprise me if someone responds with a link to a story that your average marsquake would be about 80 on the richter scale.

Re:

[ittybad]

Well, while the mountains are vastly larger, your comparisons are misguided. The red spot? Wrong planet. Your think Jupiter. Big Earth-quake? Can't hit 80. The scale only goes to 10. Anything worse than a 10 is still a 10. At any rate, would that not be called a Mars-quake?

Re:

[wattrlz]

You're thinking of the warp scale. The richter scale goes up past ten, it's just that, being a logarithmic scale, getting up to and beyond ten would require energy on a scale not often discussed outside of astronomy or science fiction.
