  • I don’t know why people insist on trying to diss SpaceX anytime there’s space news… Anyway, last time they missed the Autonomous Drone Ship was years ago when they were first trying to land. So I’m not exactly sure what you are referring to.

    Plus, with space missions there are usually many different mission objectives, and with this mission the main mission was to “demonstrate its highly precise navigation and landing system” which they determined to be a success. The extra credit mission would be if it landed properly and they were able to do more science with it.


  • If you understand gravity wells, think of L1/L2/L3 as the shape of a saddle. If you’re right in the middle of the saddle it’s a pretty stable orbit, but if you get too close to any of the edges you fall right out of it. L4 and L5 are like the peaks of a mountain.

    Also worth pointing out that only L4 and L5 are stable, L1/L2/L3 are only metastable where they require a bit of maintenance to stay there.

    Another fun fact about Legrange Points: There’s a group of asteroids called the Trojan Asteroids. There’s technically two groups of these since they’re stuck in L4 and L5 in the Sun/Jupiter system.
