NASA’s Perseverance rover has made a groundbreaking discovery on Mars — evidence that the Red Planet may have hosted habitable environments multiple times throughout its history. In the Jezero Crater, scientists found over two dozen minerals formed through interactions with flowing water, revealing three distinct episodes of water activity. From acidic and harsh conditions to cool, alkaline waters ideal for life, Mars has a far more dynamic past than we ever imagined.

Could life have started — and restarted — on Mars?

00:00What if I told you Mars didn't just maybe host life once?
00:03But several times?
00:05NASA's Perseverance rover just dropped a bombshell from Mars.
00:08In the ancient Jezero crater,
00:10scientists discovered two dozen minerals shaped by flowing water.
00:14Not once, but three separate times.
00:17Each episode changed the planet's surface in powerful ways.
00:20The first was harsh—acidic, boiling water
00:23that would have crushed most life as we know it.
00:26The second? Much better.
00:28Cooler, neutral water across a larger area.
00:30Life could have had a real shot.
00:32And the third?
00:33It was the jackpot—low temperature, alkaline water, spread wide.
00:38The kind of conditions where life loves to thrive.
00:40These discoveries reveal that Mars wasn't just a frozen desert.
00:44It evolved through waves of habitability.
00:46And Earth-like minerals tell us.
00:48The red planet might have been blue more than once.
00:51So, is Mars dead?
00:52Or are we just now uncovering its living history?
00:55NASA's not just looking for life.
00:57It's tracking the chapters of an alien story written in Martian rock.
01:01The 2nd.
