Water on Mars, ice on the moon

[Nickelson Profile]

On the basis of High Resolution Imaging Science Experiment (HiRISE) images of two successive years we observed changes of a gully on the Russell crater dune field. Within the first year the length of a ∼2 m wide incised gully channel grew about 50 m downslope, and ∼120 m within in the second year. Gully activity occurred in early spring between LS ∼198° and ∼218° in the first year and between LS ∼192° and ∼221° in the second year. Based on the channel morphology, spectral data and modeled surface temperatures, the changes can be best explained with transient melting of small amounts of H2O-ice triggering slurry flows consisting of sand mixed with liquid water.

We present new polarimetric radar data for the surface of the north pole of the Moon acquired with the Mini-SAR experiment onboard India's Chandrayaan-1 spacecraft. Between mid-February and mid-April, 2009, Mini-SAR mapped more than 95% of the areas polewards of 80° latitude at a resolution of 150 meters. The north polar region displays backscatter properties typical for the Moon, with circular polarization ratio (CPR) values in the range of 0.1–0.3, increasing to over 1.0 for young primary impact craters. These higher CPR values likely reflect surface roughness associated with these fresh features. In contrast, some craters in this region show elevated CPR in their interiors, but not exterior to their rims. Almost all of these features are in permanent sun shadow and correlate with proposed locations of polar ice modeled on the basis of Lunar Prospector neutron data. These relations are consistent with deposits of water ice in these craters.

This is actually the same thing as saying.

WE ARE NOT ALONE AND E.T IS NEARBY!

My sense is telling me we're coming closer and closer to full disclosure by the officials IMO.

Well thanks, but I think I am in the wrong place here regarding space news. No replies what so ever

Where there is water, there is life is it not?

I tend to agree, although maybe not the life as we know it, we might not even recognize it... but cool article anyways heheh

But shouldn't it be: Water on the Moon, Ice on Mars...? Or do I suddenly have my astrophysical knowledge wrong

On your last statement I think it goes both ways.
They found meters thick of ice in the northern craters of our Moon and floating water on the surface of Mars. That's what they claim though.

And to reply on you first statement. We wouldn't even know it if it in some cases stand right in front of us.

But life which is similar as life as we know it also is out there, you can bet your mother in law on that.

True all the way, just had to think again for a while.... although I don't have a mother in law... but if I had, I would deffinetly make the bet
