You might be wondering about life on Mars after our Performance Assessment (Three-Week Test). In the test, you had to make models of 4 compounds. Yes, all four of those compounds have been found on Mars. Only methane is organic, and it's only found in the atmosphere. It was probably not made by living organisms.

THERE HAVE BEEN NO OTHER ORGANIC COMPOUNDS FOUND ON MARS! So, there's still no direct, solid evidence of life there. Scientist still keep looking.
