    I think the only one that can solve all of their problems is elon. He would fix it in few weeks. Include him in next launch, he will troubleshoot directly on the Moon. Please, someone, send that asshole to space.

        That sank into a crater. So we built a third one. That burned down, fell over, and then sank into a crater. But the fourth one stayed up. And that’s what you’re going to get, Lad, the strongest spacecraft on all of the Moon.

      The biggest problem with RTGs is the extreme cost and lack of availability. Pu-238 is very expensive and at any moment, there’s only tens of KG of Pu-238 available for RTG use. They’re not really a reasonable choice for private industry at this time.

        As true as that is, they said that it cost them hundreds of millions of dollars, and the mission was only planned to last from 10 to 14 days or so. They could have used just a piece of a waste uranium rod or something as an alternate power source for such a short-lived mission.

        I mean yeah, of course that would still add to the cost and complexity, and I don’t even know what all that would take, but hell if you’re already into the hundreds of millions of dollars range, you ought to consider redundancy and alternate power sources.

          I imagine it’s more complicated than that. For example, Pu-238 only emits alpha radiation. I doubt that reactor waste only emits alpha radiation, meaning you’d have to harden the electronics for a close and potentially extreme emitter of beta/gamma radiation. I also don’t know if random high grade reactor waste gets hot enough to provide meaningful amounts of energy via thermoelectric means. Alternatively, it may be that it gets too hot.

          I doubt they could have simply slapped something together. The cost of developing a new RTG capable of using reactor waste would likely be a significant fraction of the budget to develop the probe itself. It might have been worth it, but I feel that it’s not clear-cut.

      They also used the same design of a prior craft that met the same fate. But private industry are problem solvers. 🙄

      Eh… I think they should stick to solar power. Given how much trouble they’ve been having, let’s not give them any weapons grade isotopes…

      For what it’s worth, just last week, Firefly stuck the landIng on their first attempt. They’re seriously killing it these days, I’m happy for them.

        Solar power? On the south pole of the moon?

        That would just barely work on its own, even if the thing didn’t topple over.

    When one day we get people back on the moon, is there a chance these devices could be brought back online?

      Well, if we have boots on the moon, at that point we don’t need probes like these. At that point you just drop a sensor, or whatever experiment you want directly on the surface.

        I was looking at it from the perspective of all the failed probes we’ve sent and whether or not the lost costs/missions could be recouped or completed somehow.

      Brought back*

      No need for this trash on the moon, even if it works.

    Landing a fridge on those spindly little legs did seem a bit… optimistic…

      I really don’t understand the tall moon lander strategy… I mean, if you’re going to design it with a high center of gravity, then design it to fall over… Just use two landing legs instead of four, to ensure it falls over the right way. Then you put the solar panels on the side, so that when it topples over they’re facing up.

      I’ve literally done this in Kerbal space program, it’s a pretty reliable landing system if your probe is tall.

    Seems Firefly Aerospace has got this all sorted, though. Amazing feat for them last week to have a flawless landing.

    This could have potentially happened to Apollo 11, had Armstrong not taken over manually to steer clear of the targeted landing site with some rough areas. Maybe it would have been just leaning and not a big deal, but at the time we had no clear idea what a real landing would end up like. And I would hazard a guess that even though we’ve done a lot over the decades, the polar regions of the Moon are still pretty unknown.
