A vein-filled rock is catching the eye of the science team of NASA ’s Perseverance rover.
The arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopic life in the distant past.
The rock exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago .
Other explanations for the observed features are being considered.
A key objective of Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life.
Could the olivine and sulfate have been introduced to the rock at uninhabitably high temperatures creating an abiotic chemical reaction that resulted in the leopard spots?.
