ISRO's Mars Orbiter on Tuesday sent pictures of Phobos—the largest of the two natural satellites that orbit around Mars. The national space agency also shared some time lapse photos on its social networking site.
Phobos along with the Mars' another natural satellite Deimos was discovered in 1877. Phobos was nearing Mars at a rate of 1.8 m every hundred years and at that rate, it would either crash into the red planet in 50 million years or break up into a ring, says NASA, the US national space agency.
