    This is awesome! Really excited to see new activity happening there.

    But I keep getting hung up on one detail in the article:

    It carried a vacuum to suck up moon dirt for analysis

    Does anyone know more about this? The lunar surface effectively is a vacuum, so I wouldn’t expect it to work at all. Why not just scoop up the samples?

      On its own, it would not work. Part of the test is actually to test the vacuuming technology, including the approach of brining the necessary gas along with it...

        Ah, thank you for the context! This is a good quote about it: Makes a lot of sense that they want to reduce the possible points of failure by going as solid-state as they can.

        Ah, thank you for the context! This is a good quote about it:

        “There’s no digging, no mechanical arm to wear out requiring servicing or replacement – it functions like a vacuum cleaner,” Harris said. “The technology on this CLPS payload could benefit the search for water, helium, and other resources and provide a clearer picture of in situ materials available to NASA and its partners for fabricating lunar habitats and launch pads, expanding scientific knowledge and the practical exploration of the solar system every step of the way.”

        Makes a lot of sense that they want to reduce the possible points of failure by going as solid-state as they can.

          It's usually an interesting consideration when you trade risk of failure/cost of redundancy of the mechanical mechanisms with the limiter and cost of bringing your own fuel. I suspect that this...

          It's usually an interesting consideration when you trade risk of failure/cost of redundancy of the mechanical mechanisms with the limiter and cost of bringing your own fuel. I suspect that this approach is driven primarily as a test and proof of technology, and at some point later down the line it will be considered within the context of a larger trade study.

    Bit of a sad sentence there amid a mostly optimistic article. I wonder what effects, if any, this sort of debris will have on the moon for future generations.

    The moon is littered with wreckage not only from ispace, but dozens of other failed attempts over the decades.

      I’m not condoning the debris but it’s important to keep a sense of scale. The surface area of the Moon is about the size of Russia, Canada, Australia, and India combined. Whatever impact our little wreckage has caused there is a tiny, tiny drop in the bucket.

        Not only is it a drop in the bucket, we're increasing the value of a future degree in lunar archeology. Won't someone think of the future lunar archeologists?

          Those moon whalers are really gonna throw a wrench in their doctorate programs..

        Oh definitely, I'm not saying it's a huge deal or anything. I was mostly just wondering if there are any unforeseen issues that leaving something on the moon could cause (though of course if we know about it then it wouldn't be an unforeseen issue...). Like there's not really any environment there to fuck up, so maybe it's a moot point. Just curiosity is all.

          Fun fact: Space probes are sterilised to avoid bringing with them microorganisms from Earth to other celestial bodies. There's probably no chance they would survive on the Moon, but some extremophiles might potentially survive in "friendlier" climates, like Mars, Venus, Europa, and Titan.

      It's uh... going to give my mom so. many. options. to plan to visit when we go on that family moon tour in 20 years? I for one can't wait to rent my first pedal powered lunar rover. Not too sure...

      Not too sure how exciting the Mare Imbrium zip line is gonna be. But, yes, I'm going to ride it. And YES I'm going to buy the T-shirt.
