Video: NASA's Curiosity Rover Finds Old Streambed on Mars

Source - NASAtelevision for Sep 27, 2012:

"NASA's newest Mars rover has found evidence that a stream once ran vigorously across the area on the Red Planet where the rover is now driving. The finding is a different type of evidence for water on Mars than ever found before. Scientists are studying Curiosity's images of rocks containing ancient streambed gravels. The sizes and shapes of stones cemented into a layer of conglomerate rock are clues to the speed and distance of a long-ago stream's flow."

Curiosity Finds Old Streambed on Mars

Curiosity has found evidence that a stream once ran vigorously across the area on Mars where the rover is now driving.

Here is a quote from that article:

 "From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep," said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. "Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we're actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it."

Why Curiosity Matters

A former rock-n-roller turned NASA engineer explains why he thinks Curiosity--both the Mars rover and the human desire to learn new things--matters to ordinary people on Earth.
