With NASA trying really hard from quite a few years to find water on the surface of Mars, they have been collecting real good proof over the years. To add another evidence to the lot, Curiosity, the Rover sent by NASA on Mars, came across pebbles near the Gale Crater. Pebbles are usually formed when they are eroded by wind or water, and these pebbles seemed pretty close to the ones formed due to water, the same way as on Earth. Pebbles roll and bump onto other pebbles and settle at places, eventually forming their well rounded edges. Wind couldn't be the reason behind them since these pebbles seemed too big, about 1.5 inches in diameter. These kind of pebbles have not only been found near the Gale Crater but also on other parts of the Red Planet.
Many rock formations and landscapes on Mars have been found to look similar to the ones carved out of rivers and streams on our planet, still adding to the possibility that water once flowed over the barren planet. The parts where these pebbles were found are reported to have had ankle deep water and sometimes have been waist deep. The pebbles have also been analysed and found to have not travelled a distance more than nine miles.
Mars has always been in the news frequently, with Curiosity finding something interesting almost every month. This planet is supposed to be the closest to the conditions seen on Earth, but with time Mars might have died away. The people at NASA are determined to find water on the dusty planet and are really hoping in to bump into extra-terrestrial life up there soon. And while Curiosity keeps on looking for more, we anticipate some great discoveries to be unveiled.
