  • Too little

    Too many empty pauses. Too much uninteresting small talk. Too little good solid astronomy talk. Please unsubscribe me. Thank you. Also, one needs to send a “nickname” with the comment. I tried 3 and all were “taken.”

  • Mostly Gems

    Mostly Gems, some duds, but if you like, love, or live astronomy there's something in it for you. And it's daily(compiled here weekly)! Open up your mind, truth is stranger (and way more fun) than fiction.

Ep. 753: Why is the Moon's South Pole So Interesting?
Q: Is landing at the South Pole of the moon more difficult than landing elsewhere on the moon?
Yes, landing at the South Pole is significantly more difficult due to complex geology and the need for more propulsion to change orbits.

Q: Will it be safer to mine the asteroid belt in other locations than the moon, considering how important the moon is to the Earth?
