Utopia Planitia is the largest recognized impact basin on planet Mars. Recent researches conducted by the Shallow Radar (SHARAD) instrument have discovered aqueous deposit underneath. The thickness of this deposit ranges from 80 metres to 170 metres below the surface of the planet. The content is spread in an area much greater than that of the seven sister states put together!

Mars is smaller than Earth. Its density and mass is also lower than earth. Since all these factors are lower, its gravity is also lower than Earth. In fact, the gravity on Mars is 62 per cent lower than Earth, meaning the Martian gravity is 38 per cent of the gravity on Earth. So a 50 kg person on Earth would weigh 19 kg on Mars.

The researchers at the California Institute of Technology say that an ancient delta was found on Mars. Using high-resolution images of a spanning 100 square kilometre area from the Mars Reconnaissance Orbiter (MRO), the researchers discovered the fan-shaped inverted channels that appeared to be emptying into an ancient ocean. The inverted channels appeared as ridges that were made from sediments of coarse material. Slope measurements indicated that the water was spreading out instead of converging. This suggested that these water channels were part of a delta. The researchers also found an abrupt increase in slope downstream suggesting that waters must have emptied into a larger body of water. Since there is no crater nearby, it was suggested that this large body could have been an ocean.

The red dirt in Central Australia closely resembles the red surface of Mars, which also explains the abundant formation of gem-quality opal in the red dirt of the Great Artesian Basin in Central Australia. It is referred to as ‘Mars on Earth’.
