Summary

Story summary

Recent Mars studies show organic molecules can survive for tens of millions of years when trapped in pure ice, making icy regions more promising than soils for finding microbial traces.
Scientists observed extreme winter conditions in Mars' polar vortex, where temperatures drop significantly and ozone levels rise.
Future missions, such as the ExoMars rover planned for 2028, aim to explore these icy depths for signs of life.

History

Historical Context

The Viking program, launched by NASA in 1975, successfully landed Viking 1 and Viking 2 on Mars in 1976, marking a significant milestone in space exploration. These missions provided over 4,500 images and crucial data about the Martian atmosphere, including the detection of carbon dioxide. Their findings laid the groundwork for ongoing studies into potential microbial life, influencing future missions like ExoMars planned for 2028.
