The Flow of Water Found on Mars
Mars rover robot creations National Aeronautics and Space Administration (NASA) found evidence related to the flow of water that have occurred on Mars. These findings provide evidence of the early existence of water on the red planet. This evidence suggests the rocks that once fed by the water and this is the first of its kind. "From the size of pebbles, we interpret the water was moving about 3 feet per second range in depth from ankle to hip," says scientist William Dietrich University of California at Berkeley.
He said many studies reveal about the channels on Mars with a variety of different hypotheses about the flow of water in it. This is the first time that scientists see gravel carried by the flow of water on Mars. Curiosity found this site which is located between the northern part of Gale Crater and the base of Mount Sharp. Initial image captured through the orbit of Mars may provide additional understanding of these pebbles.
A captured image shows alluvial material washed by the water and move to the edges. Spherical shape of some of the rock shows it moving from a distance, where the channel called Peace Vallis pointed to the alluvial fan. The number of channels in the alluvial fan indicates that water flows in continuous motion. The flow was also repeated each time in a long time, not just once or over several years.
