    The world of Mars long ago was likely habitable — which is why the new Mars rover Perseverancehas a suite of instruments that will get us closer than ever to confirming if there was life on Mars. Perseverance is exploring Jezero Crater, a meteorite impact site that later became a lake bed. A few lakes like thisexist on Earth today. “These environme...

    Mount Sharp appeared to have formed from layers of sediment deposited in a lakebed over tens of millions of years. The observations of the sedimentary beds revealed the conditions under which they formed. Looking at the images of Mount Sharp, the team noticed radical changes. Above the base of Mount Sharp, there were wide, tall cross-bedded structu...

    Why it matters —Of all the planets in the Solar System, Mars is the most similar to Earth. Therefore, revisiting Mars’ history allows us to peer back in time into the history of our own planet. “There is absolutely no way we're gonna learn about this on Earth because the first billion years of evolution on Earth has disappeared off the record,” Rap...

    What’s next — On February 18, NASA’s Perseverance rover landed on Mars to begin its mission of searching for clues of ancient life. Perseverance will explore Jezero Crater,a dried-up, ancient lake that may have once housed microbial life billions of years ago. Exploring Jezero Crater will provide scientists with more clues since that environment us...
