NASA's Perseverance rover might be out there on Mars since 2021, collecting rock samples and finding hints of water, but that doesn't mean its predecessor has already retired from its explorations. In fact, the Curiosity rover has been observing Martian clouds during twilight to build upon its previous survey on night-shining clouds. And on February 2nd, Curiosity captured a rare sight on camera, making it the first time we've seen crepuscular rays (or "sun rays") this clearly from the Martian surface.
