NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.<p>"You had water transporting these gravels to the downslope of the fan," NASA researchers say.

The High Resolution Imaging Science Experiment at The University of Arizona, <a href="http://hirise.lpl.arizona.edu/releases/msl-descent.php">which released the image</a>, explains:<p><blockquote><p>"The parachute appears fully inflated and performing perfectly. Details in the parachute such as the band gap at the edges and the central hole are clearly visible.

But because it takes about twice that long for signals to travel from Mars to Earth, scientists won&#39;t know anything about the landing until after it&#39;s already over.</p><p> Sun, 05 Aug 2012 11:39:21 +0000 Véronique LaCapra 4246 at http://news.stlpublicradio.org ‘Curiosity’ reaches Mars tonight: Wash U researcher helps rover traverse red planet
