Answer 2

Is there life on Mars?

While definitive evidence for past or present life on Mars has not been found yet, several discoveries over the past few decades have increased the possibility that life may have existed on the red planet at some point in its history.

Some key points:

- The Viking landers in the 1970s carried out biological experiments that produced inconclusive results which both supported and refuted the presence of microbial life. The experiments were not able to definitively prove or disprove the existence of Martian life.

- Methane has been detected in the Martian atmosphere by Mars orbiters like the Mars Express and Curiosity rover. Since methane breaks down quickly in the Martian atmosphere, its presence suggests it must be replenished from an active source like microbial organisms or underground geological processes. However, more data is still needed to confirm the origin of the methane.

- Organic molecules, which are building blocks for life, have been found on Mars by instruments like Sample Analysis at Mars (SAM) on the Curiosity rover. While these detections do not prove the existence of life, they show that some chemical conditions for life may have been present.

- Evidence from past missions and landers like Phoenix and Opportunity point to Mars having environmental conditions in the past that could have supported microbial life, such as a warmer and wetter climate with liquid water on the surface.

More missions are planned in the coming years like ExoMars and Mars Sample Return to further investigate these clues and search for definitive signs of past or present Martian life through new scientific instruments and bringing samples back to Earth for in-depth laboratory analysis. While the scientific consensus remains that no conclusive proof of life has been found so far, ongoing exploration continues to shape our understanding of the possibility of life elsewhere in the solar system.
