Probing Mars' subsurface

Relatively deep subsurface sampling on Mars has yet to be achieved, despite the number of landers that have arrived there since the Viking landers in the 1970s. Of the three space probes currently heading for Mars, the NASA and Chinese probes carry landers, while the .United Arab Emirates probe is an orbiter only.
The two Mars landers are not equipped to drill deep into the Martian soil, that operation will have to wait until NASA's Rosalind Franklin lander on the ExoMars probe is scheduled for launch in 2022.
On arrival at Mars, the ExoMars lander will be equipped for performing subsurface drilling. There's a possibility that microbial life could exist not far below the surface, and on the assumption that water is present.
Dimitra Atri a research scientist at the Centre for Space Science at NYU Abu Dhabi, said, "It is exciting to contemplate that life could exist in such a harsh environment, as few as two metres below the Martian Surface." He added, "The MarsExo lander is well-suited to detect extant microbial life and hopefully provide important insights." Its possible that a steady rain of penetrating cosmic rays could have provided enough energy to create organic activity in the Martian soil. The study is published in the journal Scientific Reports.

Our knowledge of Mars has increased significantly in recent years. So, we found out that there is no vegetation and water in liquid form on the planet, but the surface contains large reserves of ice. But we still have to learn even more: not a single research vehicle has yet returned to Earth with samples of Martian soil, and we have not found solid evidence that life once existed on Mars.

The combinations of substances in the samples that the probes will receive are very interesting. How much the minerals there correspond to the composition of the earth's minerals, how much the proportions differ. What if there are some new elements? The periodic table was also not completely created immediately.
