    I read the name and the first logical thought that came to mind was that of a platform to have AI agents iterating on rockets design. How doomed am I?

      I figured it was a typical no-info HN title; I was happy to discover it actually conveyed some meaning.

      Just reading the name I wouldn't have been surprised if it had nothing to do with rockets whatsoever - I was half expecting it to be some kind of "agentic platform to accelerate your product development" etc.

      I think I need to go for a walk.

      OpenRocket has a little optimizer built in but of course it neglects structural integrity which it knows nothing of…

    This is pretty cool. I remember having fun simulating my rockets using the BASIC programs from G. Harry Stine's "Handbook of Model Rocketry" when I was a kid. This looks like a way to recreate some of that fun.

    I helped out with a user interface redesign of OR many years ago. It was pretty incredibly unintuitive back then, and many hobby rocketeers paid for Rocksim instead.

    Well THAT's cool. I was just talking about getting back into model rocketry... I'm not sure my 6yo daughter will like it as much as I did/do but I want to get back into it and launch a few and see if she's into it. Timing here is great as I need to start looking at starting from scratch with kits etc.

      I bought my son a Estes kit about 10 years ago. He's now at University studying aerospace engineering as a direct result. So you never know!

    I wonder how crazy the scale here can get. How far can I go? The bps.space guy is heading into space. Can the community hit the moon? Literally.

      Space Concordia, a Canadian university space-oriented student group, which is sort of amateur-level given that it’s driven by students and donations, attempted to reach space not that long ago with a liquid fueled single staged rocket. Here is a video of the launch https://www.youtube.com/live/610YciEs8qg?t=4594&is=aAWo8Y7vi...

      Might be worth checking out the "Copenhagen Suborbitals" group (they have a YouTube channel) and see if they're still active! It's been years but I think I recall they were trying to build something capable of getting a person into space (not sure if orbit was a goal).

      "Space" is 100km. The moon at its closest is about 350,000km.

      So the jump from the former to the latter is... significant.

      • hermitcrab 2 minutes ago
        And you need a serious amount of money, effort and expertise to each 100km with a rocket.

      Amateur rocketry achieving orbit would be significant. Reaching the moon would be substantially more difficult.

    With the current wars this will only gain more interest.

    The miracle of 3D printing. First ghost guns, and now ghost rockets. Will be curious to see what prediction markets will have for these.
    • altruios 2 hours ago
      you get some good, you get some bad.

      Building a rocket shell is probably just fine: you need to fuel yet - that you can't 3D print. probably fine...

      Overall 3d printing is a lot more than ghost guns and ghost rockets. That the conversation dominates this small sub-section reeks of 'think-of-the-children' screeching that hides explicit power grabs in regulation and surveillance with the main intent seemingly to be 'enforce copywrite' (of only the big players that can afford to throw their weight around).

      Fear pushes people's buttons.

      i've recently had youtube randomly suggest me a video where this dude was building his own opensource manpads, with a single rocket costing under $100 in parts (there was no explosive payload so that makes it just a rocket and not a missile, i guess). not long after, someone posted it here on hn but i think it's been removed (by the mods, i imagine) since.

      i find these projects both fascinating and terrifying. seeing a single person building what normally involves huge defense corporations and government contracts, these things in their bedroom is amazing. it shows how information wants to be free and how ingenious people can get with whatever motivates them.

    I hope this is for students' project and for sending a gopro to the stratosphere?
  • evanwolf 2 hours ago
    Is there a similar drone design simulator?

    Oh i've been looking for a project for my 11 year old... he's a very project oriented learner, which schools don't seem to do anymore.

    Bookmarked :)
