> Our analyses by testbed instruments that are on or will be sent to Mars unveil that although the mineralogy of Red Stone matches that detected by ground-based instruments on the red planet, similarly low levels of organics will be hard, if not impossible to detect in Martian rocks depending on the instrument and technique used. Our results stress the importance in returning samples to Earth for conclusively addressing whether life ever existed on Mars.

This study seems to support the Mars Sample Return Mission, which has been controversial lately due to its high costs: https://arstechnica.com/space/2023/07/the-senate-just-lobbed...

> The concern expressed by some scientists, including former NASA science chief Thomas Zurbuchen, is that the ballooning cost of Mars Sample Return will cannibalize funding from other science missions. And if the price is already approaching $10 billion now, then it is likely to spiral further out of control.
