NASA's Perseverance Found Green Sand on Mars

In the Jezero crater of Mars, the NASA Perseverance rover has studied mineral rocks that are four billion years old.

Unexpected results surprise scientists

Mars orbiters discovered an olivine-rich rock formation a few years ago.

It is a mineral that is widespread on the earth and abundant.

Scientists anticipate finding sedimentary rocks at Jezero that are coloured red.

Persistence made the startling discovery that most of the rocks weren't the ordinary sedimentary rocks that rivers typically deposit at the lake's bottom.
