The @NASAPersevere Mars rover is headed for an ancient river delta in Jezero Crater.
But how long did it take for water to carve the delta's contours so many years ago?
Years? Decades? Centuries? https://eos.org/editor-highlights/how-fast-did-an-ancient-martian-delta-form

New research @AguAdvances suggests the delta could have formed in as little as a few decades... https://eos.org/editor-highlights/how-fast-did-an-ancient-martian-delta-form
NASA selected Jezero after more than 5 years of discussion.
"The landing site in Jezero crater offers geologically rich terrain, with landforms reaching as far back as 3.6 billion years old." https://eos.org/articles/martian-crater-will-be-the-landing-site-for-a-future-rover

The history of water on Mars and its 'great drying' has been an ongoing mystery

Scientists can trace ancient river shapes and calculate the distances between their meanders. Using these metrics, they inferred that Mars’s rivers once roared with intense runoff events.

@NASAPersevere will assess Martian geology and analyze surface targets for signs of ancient life. https://eos.org/science-updates/seeking-signs-of-life-and-more-nasas-mars-2020-mission
Cool @NASAPersevere rover gadgets: Two instruments on its robotic arm will permit researchers to study rock surfaces with an unprecedented spatial resolution (features as small as about 100 micrometers).
