"Reservoir of liquid water found deep in Martian rock. Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet.
The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which touched down on the planet back in 2018. " (BBC website)

Searching for stuff out is space, has nearly always been centred on the search for ET life. The probability of finding life is not really quantifiable, because calculating the likelihood requires using parameters which are extremely variable and requires assumptions over which we have no prior knowledge.

We have assumed that conditions for life, must be broadly consistent with our own on Earth. However, we are finding organisms that can live and flourish in extreme conditions on Earth.
Mars' conditions are broadly similar to Earth's, except for the reduced oxygen content of the atmosphere, and lack of water.

Until now.

Water is considered one of the major elements in the creation an sustainment of life. I suppose another spacecraft will have to be sent to sample the water on Mars to see if it contains any life.
