The Spin

Scientists have long been fascinated by the idea of discovering liquid water on Mars. The most recent findings give evidence that Mars possesses liquid water under its surface, in addition to the frozen water visible at its poles. If confirmed, this discovery would be game-changing for scientists interested in the possibility of life on Mars and the continuing effort to determine the planet's habitability.

Finding liquid water on Mars suggests there could be life, but as of yet, no life has been detected. According to the dominant theory, Mars never had life. Even though Mars had the same basic ingredients as early Earth and similar watery conditions, it never had the necessary conditions for life to develop. There were inorganic geological and chemical processes, but no organic life on Mars. The Sun removed Mars's atmosphere over three billion years ago, drying out any liquid surface water and causing its current appearance.

There is an 11% chance we will find life on Mars by 2050, according to the Metaculus prediction community.
