China’s Zhurong Rover Finds Evidence of an Ancient Ocean on Mars
China’s Zhurong Rover has made an exciting discovery on Mars! Scientists believe that a huge ocean once existed on the planet. This is a big step in understanding Mars’ history and whether it once had life.
Zhurong Rover’s Discovery on Mars
The Zhurong Rover, part of China’s Tianwen-1 mission, was active from May 2021 to May 2022. It traveled 1.9 kilometers on the Martian surface and studied the ground using Ground-Penetrating Radar (GPR). This special tool helped scientists look 260 feet deep into the planet’s surface.
The rover found sand layers between 33 to 115 feet thick, which look like coastal shorelines found on Earth. This suggests that billions of years ago, Mars may have had an ocean.
Did Mars Have an Ocean?
Scientists believe that about 3.5 to 4 billion years ago, Mars had liquid water on its surface. The ocean, called Deuteronilus, may have covered a large part of the planet. The climate at that time was warmer, and the atmosphere was thicker than today.
Where Did Mars’ Water Go?
Over time, Mars lost its water. Some of it escaped into space because the planet has a weak magnetic field. But some water may still be trapped under the surface in the form of ice or underground lakes
Why is This Discovery Important
This discovery helps scientists understand if Mars was ever habitable. If there was an ocean, then life may have existed on the planet. Future missions will explore Mars’ subsurface to find more evidence of water and past life.
FAQs
1. What is the Zhurong Rover?
