@alexanderb you might have shared this already so appologies if it’s been asked.
What telescope are you using and is it computer guided?

I feel that every week should be robotics week 🙂
These STEM topics should be part of our children’s education and environment. I can’t help but feel that they passed this resolution to score political points more than anything.
I’ll be impressed when this stuff is passed through the various school boards as part of the mandatory curriculum ????

I tend to agree with @paulrenaud – Python is a must.
I’d stay away from C++ if you’re just starting. Steep learning curve but also used less and less these days. See below…

I’ve seen a live talk by one of their other founders a few years ago. It’s super cool tech. I was a bit bumped at the end once he started talking about the economics of it. I forget the numbers but basically to make a dent in the CO2 levels, you need to build about 1000 of these (or 10,000 I forget) and each costs about $10M so it’s quite unclear who will pay for this. He suggested CO2 tax globally but then again you need everyone to contribute, not just the US.
So I’m hopeful but the practical implementations are complicated.

I have no personal experience with it but given what I see happening in this space in the last 10 years or so, I think it’s safe to say that no solution is bullet-proof. If you’re a small company that dedicates a significant amount of resources to cyber-security and in the end, you get hacked, the fact that your investment might have stopped the other 99% of attainments is meanless if you suffered a PR and/or IP damage.
I think the solution at the end is to just offload the problem to the tech giants (Google, Amazon, etc) and build your systems on their infrastructure. They will always have more resources than you to solve the problem. I’ve never heard of an AWS server being hacked.
That’s what Sony did after their big hack years ago – they just moved all their internal communication systems to Gmail. Other studios followed.
Just my 2c…

I have a couple of older iPhones that I can see being used for this. Let us know if you end up building it and how it went.

This is a guy I’ve been following for a couple of years and have been building his own guidance circuitry (also for sale). He’s got a pretty impressive YouTube channel showcasing all his experiments and launches for anyone interested.

Joe and his “shop” seems to be out. I guess he’s not making enough of them. Either way, too bad he didn’t make his software open source but rather provide a closed app.
I think the benefit of trial/error when building these yourself is really the best way to learn.
I would be in favor of a once a week style program that goes through the basic theory of rockets (i.e. what is thrust, TVC, earth’s orbits, etc). Someone has to curate it though into digestible slides and video clips found online. Perhaps at two levels, one for younger ages (9-13?) and 14-18. If coupled with home experiments students can do at home on each week’s topic, it can be quite a valuable learning experience. Just an idea.
As a side note, here’s a guy who 3D printed his Starship vehicle but opted to use 2 electric motors rather then solid propellants: https://youtu.be/RKs3HPcVy_Q
