Aero-News Quote of the Day

"CRISM spotted carbonates here years ago, but we only recently noticed how concentrated they are right where a lakeshore would be. We're going to encounter carbonate deposits in many locations throughout the mission, but the bathtub ring will be one of the most exciting places to visit."

Source: Briony Horgan of Purdue University in West Lafayette, Indiana. the lead author of a paper published in the journal Icarus that identifies distinct deposits of minerals called carbonates along the inner rim of Jezero, the site of a lake more than 3.5 billion years ago. On Earth, carbonates help form structures that are hardy enough to survive in fossil form for billions of years, including seashells, coral and some stromatolites - rocks formed on this planet by ancient microbial life along ancient shorelines, where sunlight and water were plentiful.
