Shocking! Asteroid strikes brought water on Mars, says study

As scientists have been exploring Mars through the amazing technology onboard the NASA Curiosity Rover, the belief that asteroids and meteorites played a big role in the planet's development is getting stronger. While conclusive evidence for these suggestions have not been found yet, many studies have come out highlighting how the existing evidence points towards extraterrestrial evolution. A study released earlier this year claimed that life on Mars could have begun due to asteroids that brought primitive unicellular organisms to the red planet. And now, a new study has shockingly claimed that even the water on the planet was delivered through a series of asteroid strikes.

The study was published in the Science Advances journal and focused on the crust of Mars to identify whether the existence of water was native or had extraterrestrial roots. The basis of this hypothesis is analysis of 31 space rocks from Mars that have been discovered on Earth. These were water-rich carbonaceous asteroids which were probably large enough to fill out a large lake.

The study suggests that the water was present on the asteroids as solid ice. But once it struck the red planet, enough heat was released to instantly melt the ice and create water. If multiple such asteroids would impact Mars, it could be the primary source of water by creating a global ocean about 300 meters deep. But the theory does not stop there. It also suggests that water on Earth could have been brought here the same way.

But sadly this postulate cannot be investigated further. “The observation that water-rich asteroids bombarded Mars means that there may also have been a contribution to Earth, but this is difficult to quantify. Unlike Mars, Earth has plate tectonics and
