The first images of the underground part of Mars surprised scientists

The research team, led by scientists from the University of California, Los Angeles and the University of California,

Oslo found that the rock layers under the bottom of the Jezero crater, observed by the ground-penetrating radar of the Perseverance rover, are unexpectedly tilted.The position, thickness, and shape of these sites suggest that they were formed either by slowly cooling lava or appeared as natural deposits in what used to be a lake.

Perseverance is now exploring a delta on the western edge of Jezero Crater.The river once fed an ancient lake, leaving behind a large accumulation of mud and rocks that it collected along the way.As the rover collects more data, scientists will learnAnd recently, the rover provided the first images of the subterranean rocks of Mars.They were made by the RIMFAX (Radar Imager for Mars' Subsurface Exploration) scanner.

"We were quite surprised to find the stones stacked at an oblique angle," explains David Page, a professor at the University of California, Los Angeles, and one of the lead researchers on the RIMFAX scanner." We expected to see horizontal rocks at the bottom of the crater.They may have formed when molten rock rose to the surface, or they may have been old delta deposits buried in the crater floor."

The author of the study noted that most of the data collected by the rover so far indicatesBut based on the RIMFAX data, scientists can't yetto say exactly how the inclined layers were formed.

RIMFAX obtains images of underground objects using radar waves that bounce off rock layers and other underground "obstacles."The shapes, density, thickness, angles, and composition of objects affect how radar waves are reflected, creating a visual image.
