    ne of the best series I have ever read (heard on audiobook). Absolutely unique, and alternately exciting and funny. Real good, hard sci-fi.

    Sorry, can't do that. The problem with AI is that most of it is just image and pattern recognition. We're still a long ways from critical thinking or actual sentience. So we're going to need your brain in a robot to handle what the AI can't on the Mars robot slave colony. Just don't be one of the first volunteers. They may end up being the equivalent of a lobotomized house cat.

    I agree that would be, "we missed having a bad day", but even worse would be that color imagine from the decent stage after failing to cut the cables connecting it to the descent stage, showing the Skycrane flying off to make its own uncontrolled landing on the surface, a safe distance away from Perseverance, but to our horror, Perseverance is being held captive.

    I entered "rent 3d printer near me" into Goggle search and was surprised how many places around me rent 3d printers.
    This was under that search result too:
    How much does it cost to rent a 3D printer?
    For $50-$150/week you can bring a printer into your home. Build the parts you need for your project, try out a specific printer before buying, or just find out what 3d printing is all about.

    Taking that one step further:

    Depending on your 3D printing desires, renting could be a substantial percentage of buying outright.

    After watching a few YouTube videos on 3d printers, I would also add to your comment that 3d printing has a learning curve that doesn't make renting really practical either, so having an experienced friend with one would be nice.

    Some of those NASA models are cool and can see my bookcases being filled with them.

    That is cost heavy. In two weeks rental you could own one.

    My latest. I bought it for less last black Friday.

    I downloaded a few of the NASA 3D files. The ones I tried (shuttle, ISS and Saturn 5) were not in STL format. they are in MAC OS 3DS format.

    I used anyconv.com to convert them and the Saturn 5 was way too small / low res to be useful. The shuttle was too complex and large but also unusable.

    Their selection of 3D printable STL files is more limited. bummer.

    Being that "Blue is Good and Red is Bad"... The scale involved in this picture is going to be critical in getting the rover out of where it is, and then traversing the 1.7km to where it was supposed to land, and then to the actual crater they want to explore.

    [​IMG]

    From this altitude, it looks like the rover is surrounded in all directions by "bad" with only a few small, narrow pathways to get out of the red and back onto the blue. :notsure:

    Really it just depends how bad the red really is. Red was bad for landing, but might not be that bad for travel. They've said they're more concerned about sand than traveling over rocks. We'll probably see how bad the red areas are when we get that sweet high def landing footage.

    Good points.

    I can't wait to see the landing footage as well as some of the driving and drone footage. That is, provided NASA decides to share any of that with us peons.

    Blender and you can scale things a lot. I think there's also a 3d printing thread somewhere...

    For 400 you can get a pretty good one that doesn't need much tweaking since it's self levelling (CR-6)

    Also, you can always try the local library.

    There really aren't any printers under 1,000 that are not going to require tweaking and modifying. They'll work for now, but give it 2-3 months and you'll be troubleshooting them, finding out they cheaped out on the parts, and then upgrading them.
