Hey friends! Join us today for an info-packed episode of the Space Nuts podcast. We'll dive into Ingenuity's bittersweet end after a groundbreaking 72 flights on Mars. Stick around to hear the upside-down lunar landing tale of Japan's SLIM mission and the passing of physics giant Arno Penzias. Plus, new insights on our galaxy's weird dark matter halo that might make the Milky Way unique. We'll round it out with a possible explanation for Mars' mysterious methane burps. Lots of space news and expert analysis from astronomer Fred Watson - let's jump in! I'll kick things off sharing the latest on NASA's Ingenuity Mars helicopter. After exceeding all expectations, its last attempted flight ended with a broken rotor blade. But the tech demo accomplished its goals and more - flying over 10 miles in nearly 3 years! The data gathered will inform future aerial explorers like Dragonfly destined for Saturn's moon Titan. Shifting to the moon, I'll recap Japan's SLIM lander mission. It successfully touched down in January but toppled over, landing upside down on the lunar surface! Still, it beamed back images including a cheeky shot of its own rocket nozzle pointing skyward. While not all experiments will work properly, the team did demonstrate superb precision landing. We'll take a moment next to remember the late Nobel laureate Arno Penzias. He helped cement evidence of the Big Bang by chance while testing a radio antenna in 1964. Stay tuned to hear the pigeon poop story! After that, new measurements of stars in our galaxy's outskirts suggest our dark matter halo drops off uniquely compared to other galaxies. I'll unpack what that might mean for the Milky Way's structure and evolution. Finally, simulations point to a possible atmospheric pressure driver behind Mars' puzzling methane plumes.
