Mars may have had rings, & may come back- Scientists

March 23, 2017

A new model developed by scientists at Purdue University in the U.S. suggests that debris that was pushed into space from an asteroid slamming into Mars around 4.3 billion years ago alternates between becoming a planetary ring and clumping together to form a moon. According to one theory, Mars’ large North Polar Basin or Borealis Basin  which covers about 40 per cent of the planet in its northern hemisphere  was created by that impact, sending debris into space. That large impact would have blasted enough material off the surface of Mars to form a ring,” 

 

Know More about Mars:

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.

 

The Mars Orbiter Mission (MOM), known as Mangalyaan is a space probe orbiting Mars since 24 September 2014. It was launched on 5 November 2013 by the Indian Space Research Organization (ISRO). It is India's first interplanetary mission and ISRO has become the fourth space agency to reach Mars, after the Soviet space program, NASA, and the European Space Agency. It is the first Asian nation to reach Mars orbit, and the first nation in the world to do so in its first attempt. The total cost of the mission was approximately ₹450 Crore (US$73 million), making it the least-expensive Mars mission to date.
