Perseverance has probably discovered signs of Martian life by now

If signs of life really exist on Mars, the Perseverance rover has probably detected them by now. has discovered. Ground-penetrating radar images show the rover is probing the perfect spot for fossilized microbial life.

Perseverance, or Percy as the mission team calls it, has confirmed that at least one of the red planet’s craters was filled with water in the distant past by wandering through a three-billion-year-old landscape on Mars.

Scientists strongly believe that Yezero Crater once had a deltaic system; Because its surface shows signs of a dried up lake bed into which an ancient river flows. For this reason, the Perseverance rover was sent to investigate this crater in February 2021.

Now that researchers can peer beneath the dusty surface of Zero, it’s more likely than ever that Percy has already shown signs of extraterrestrial life. David Page, a planetary scientist and lead author of a new study on subsurface observations on Mars, explains:

From the orbit, we see a collection of different sediments, but we cannot say with certainty that we see them in their original state or that they have undergone long-term surface changes. To understand the formation of these structures, we must examine the subsurface.

Among the seven Perseverance instruments, the ground-penetrating radar, abbreviated as RIMFAX, is the best tool for investigating the subsurface of Mars. This system has the ability to detect ice, water or brine more than 10 meters below the ground surface and can map layers of soil and rock up to 20 meters deep.

Perseverance has spent much of the past year exploring the western rim of Yezero Crater, using its radar to probe its subsurface. The collected data have now provided an unprecedented view of the Martian subsurface in a place where scientists suspected a lake existed.

Subsurface imaging has seriously confirmed scientists’ suspicions. An international team of researchers has found evidence beneath a suspected delta that suggests a 4-billion-year-old impact crater formed by an asteroid impact was later filled with younger rocks and sediments.
