NASA finds 500-meter-long track on Mars

NASA scientists have discovered a nearly 500-meter-long track on Mars. But, the strange dotted path was not left there by aliens; rather it was created by an irregularly shaped boulder that zigzagged downhill.

The images of the track were first captured and sent to back to Earth by the High Resolution Imaging Science Experiment (HiRISE) camera of the American space agency's Mars Reconnaissance Orbiter on July 3 this year.

The Mars Reconnaissance Orbiter, which has six high-tech science instruments, including HiRISE, is being managed by NASA's Jet Propulsion Laboratory, a division of Pasadena-based California Institute of Technology.

The long trail left on the slope by the tumbled rock has a pattern that suggests that the rock was irregular and could not roll straight and smoothly.

It came to rest with its longer dimension vertical. In the downward-looking reflection, the rock looks just 11.5 feet (3.5 meters) in width. The shadow cast by it in mid-afternoon sunlight suggests that it is around 20 feet (6 meters) in height.

The tumbling of the huge rock on Mars showed that unchanging surface of the Red Planet is also subject to some of the same natural forces that we see on earth.
