"NASA’s Ingenuity Mars Helicopter acquired this image using its navigation camera. This camera is mounted in the helicopter’s fuselage and pointed directly downward to track the ground during flight. This image was acquired on November 6, 2021 (Sol 254 of the Perseverance rover mission) at the local mean solar time of 12:06:00. This was the date of Ingenuity’s 15th flight.

NASA's Ingenuity helicopter made its 33rd mission to Red Planet's atmosphere. The interesting detail in this mission is one piece of foreign debris that is found on the surface. That debris is one of the most interesting things what that small helicopter has seen.
But Ingenuity itself is an interesting system. A similar system that uses nuclear batteries can use to map the high atmosphere of gas giants like Jupiter and Saturn. And also Ingenuity can use to map the Venus and Titan moon.

"Perseverance Workspace at ‘Skinner Ridge’: NASA’s Perseverance rover puts its robotic arm to work around a rocky outcrop called “Skinner Ridge” in Mars’ Jezero Crater. Composed of multiple images, this mosaic shows layered sedimentary rocks in the face of a cliff in the delta, as well as one of the locations where the rover abraded a circular patch to analyze a rock’s composition.

One of the most interesting questions is could the Ingenuity or Perseverance find life on Mars?
The fact is that there is remaining organic material and structures that look like ancient bacteria. There are theories that Mars has changed its trajectory during history. Also, that planet faced even more violent geological upheavals than Earth. Mars lost its entire lithosphere.
So there is a possibility. That on Mars-planet was some kind of primitive lifeforms like procaryotes that are similar to cyanobacteria on Earth. But that thing requires more research to confirm.
If the positions where researchers find those bacteria are very rare. That tells they are coming from somewhere else than on Mars. But where lifeform can come from? One possibility is Earth.
There is the possibility that the bacteria traveled to Red Planet with probes that are not well-sterilized. But that thing means. There should be DNA (or RNA) molecules in the bacteria remnants. If bacteria is transferred to the Martian rock, that requires its living. If there is no DNA or RNA remnant, that means there should be some reason for that.
Of course, the UV radiation of the Sun can explain why some bacteria are lost their DNA. But if the position where those fossils are found is mainly in shadow. That means the UV radiation will not reach those bacteria.
The requirement that the UV radiation destroys the DNA or RNA is that the radiation can touch that molecule. If that molecule is in shadow that denies the possibility that the UV can destroy it.
One interesting place where researchers can search for life or remnant of lifeform is the asteroid or dwarf planet Ceres. There is some kind of cryovolcanic activity on that asteroid.
If there are similar bacteria or bacteria remnants that are found on Mars, that thing causes a re-estimation of the place where the first organisms came to Earth. But the first thing is that researchers must make sure that the fossils are bacteria remnants. Without DNA or RNA bites that thing is almost impossible.
