Alien Life

In 2025, detailed analysis of rocks collected by NASA's Perseverance rover has uncovered tantalising clues suggesting past microbial life on Mars. Features like 'leopard spots' and greenish mineral nodules resemble those linked to microbes on Earth. However, confirming these signs requires returning the samples to Earth, a mission now at risk of cancellation.

The initial excitement stemmed from a possible detection of dimethyl sulphide, a molecule linked to life on Earth. However, further observations confirm only methane and carbon dioxide in the planet's atmosphere.
