Avalanche on Mars

I love the NASA site!



An Avalanche on Mars

Explanation: What caused this sudden cloud of dust on Mars? An avalanche! The first avalanche imaged in progress on another planet was recorded last month on Mars by NASA's robotic Mars Reconnaissance Orbiter. Visible in the above picture, digitally rescaled, are several layers of white ice thawing over red rock, with darker colors toward the right indicated Martian soil that mixed with lesser amounts of ice. As the cliff of over 700 meters high was thawing, falling ice crashed down raising plumes of ice and dust so thick they cast visible shadows. The scarp has slopes with grades greater than 60 degrees. The entire scene is illuminated from the upper right by the Sun. A thaw occurs each spring in the Northern Hemisphere of Mars, as the warming climate causes solid carbon dioxide ice to sublimate directly to vapor. Studying such avalanches allows planetary geologists to better understand soil configurations on Mars.

Re: Avalanche on Mars

See, not yet sure about life on the planet but definate signs of weather irregularities!

When shall the "Global warming on Mars" crowd form?

Re: Avalanche on Mars

Bah, avalanche, boring (unless of course your a geologist I guess). I know this a bit older, but this picture clearly blows the socks off your avalanche. Both were taken by MRO.

The High Resolution Imaging Science Experiment (HiRISE) camera would make a great backyard telescope for viewing Mars, and we can also use it at Mars to view other planets. This is an image of Earth and the moon, acquired on October 3, 2007, by the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

At the time the image was taken, Earth was 142 million kilometers (88 million miles) from Mars, giving the HiRISE image a scale of 142 kilometers (88 miles) per pixel, an Earth diameter of about 90 pixels and a moon diameter of 24 pixels. The phase angle is 98 degrees, which means that less than half of the disk of the Earth and the disk of the moon have direct illumination. We could image Earth and moon at full disk illumination only when they are on the opposite side of the sun from Mars, but then the range would be much greater and the image would show less detail.

Re: Avalanche on Mars

to bad they didn't have this camera in 03, Mars's opposition was the best in 60.000 years...that would have made a spetacular photograph, this one aint bad either....

Well, I'm sure the "it's just a theory" crowd shall not form since there's little doubt this is the theory of gravity in action.

I love that movie. I know that the big thing now is to play Pink Floyd's song Echoes during the "Jupiter and Beyond the Infinite" sequence. I tried that and it does make for a good backdrop and now every time I hear the song I associate the two.

Some nice reflections on a theme;

Good samples for DJ mashers on their way to the Red planet.
