What does it mean to discover life on Mars

Is there life on Mars?

Dr. Winkler, why is Mars actually in the special interest of space research?

Mars is the most Earth-like of all the planets in our solar system, if only because its environment is similar to that of Earth. Mars is a little smaller than the earth, it has a similar morphology, i.e. texture and atmosphere. It is also the most accessible planet for us.

Mars has always fascinated mankind. Today we know a lot about the red planet from the probes that have already landed there. And there are even Martian stones on Earth: Meteorites hit Mars, loosening rocks that then reached Earth. We know that there was liquid Mars water and many minerals that we know from Earth. Scientists believe that there was an ocean there a long time ago.

Today Mars looks a bit like the earth in times after mankind can be imagined: a completely dry desert planet. However, there are also differences: Mars, for example, does not have a large moon like Earth. Therefore the climate development is much more unstable than on earth.

The information about what it could have looked like on Mars is surely not the only reason why one is so keenly interested in them?

We are interested in it for a completely different reason: the question of where we humans come from and how life is created in the first place. Does it arise relatively easily when water and chemical starting materials are available or is the process very complex and many favorable environmental conditions and long-term stability are required?
