The Entire History Of Mars Exploration Explained Slowly (For Sleep)

🔴 Right now, while you're settling in for sleep, there are robots on another planet doing science on our behalf. Perseverance is parked in an ancient dried lake bed, drilling into rocks that formed at the bottom of a lake three and a half billion years ago. Curiosity is climbing a mountain made of layered sediment, reading the geological diary of a planet that once looked a lot like Earth. The Mars Reconnaissance Orbiter is passing overhead, photographing the surface from space at a resolution sharp enough to see your car if you parked it there. And somewhere on the flat plains of Utopia Planitia, China's Zhurong rover has gone quiet — but it was there, and it drove, and it found things. This is a 2-hour calm, slow, sleep-friendly documentary walking you through the entire history of Mars exploration — from the ancient Babylonians watching a reddish point move against the stars, all the way to the sample tubes Perseverance is leaving on the Martian surface right now, waiting for a future mission to bring them home. We go slowly. We take our time. If you fall asleep somewhere in the middle, that's the whole point. 🔴 Subscribe for calm, slow, sleep-friendly science documentaries released regularly — new episodes every week.
