Whilst not definitive proof of past life in the form of preserved or residual biological matter, exploring the Martian Jezero crater the Perseverance rover has detected organic molecules, gaining insights about the Red Planet’s carbon cycles and the potential to host life as we know it—utilising its deep ultraviolet laser instrumentation with the title acronym for Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals. 
The non-uniformity of these deposits—which will be sampled and hopefully returned to Earth for further study in 2030, suggests that different catalysts were in action to synthesise or metabolise these chemicals over time, preserving them under distinct conditions, possibly consistent with biological processes.
