<p>By plying its ground-penetrating radar in the depths of Mars&rsquo;s Jezero Crater, this rover has found even older deltas buried beneath those seen on the surface from space</p>
Mars rovers are robotic vehicles designed to explore the surface of Mars. They are equipped with scientific instruments to analyze soil, rocks, and atmosphere, providing valuable data about the planet's geology and potential for past life.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is commonly used in various fields, including archaeology, geology, and environmental studies, to detect and map structures beneath the ground.
