if anyone has worked at JPL or similar, what's the best resource for learning how to make an actual Mars/Moon rover? I'm very curious about things like, what kind of wheels you need for regolith, how to manage extreme temperatures (electronics, motors, batteries, cameras), how communication works (could you have a remotely-operated lunar rover?), dealing with radiation (SpaceX works with consumer electronics AFAIK, b…

> dealing with radiation I can at least answer this part of the question. (I have had NASA contracts working on radiation tech, though not in that sector currently) You can use COTS. Just depends how reliable you want it. There's a good interview on EEV blog with one of the XPrize contestants. [0] He talks in detail about how they handle radiation (they basically don't and hope for the best). If you have a mission cr…

A few comments - I'm not American, so my best shot is probably to find ESA projects equivalent to SBIR/STTR (if any exist). Yeah Kevlar seems awesome, I didn't realize it has such a huge range of operating temperature! (probably the same goes for Spectra/Dynema, but I didn't immediately find any specs).

Thanks for everything! There's definitely more interest! I'm now going through all the links everybody posted, and all the other resources I've found... I'd be happy to chat more, here or over email (in my profile). I'm also researching other things, like engine control, comms, etc. until I know what to focus on.

Been following SatNOGS for a while now. Building on of the ground station designs has been on my to-do list for a while. Recently checked in on the website and saw the building instructions have gotten better and much clearer.

Well we wouldn't have made it without awesome contributors helping us out. Don't hesitate to join us :D

Awesome! Can I contribute? In other words, how can I, as an experienced backend developer (Java, Python, Scala, Ocaml, some C/C++) but a complete newbie in space, hardware and/or realtime systems, contribute?

Hey tomp. Of course you can. Most of our source code for SatNOGS is actually Python (and Django) and there is a lot you can do with C++ too. Check out our forums and don't hesitate to introduce yourself to the rest of the community https://community.libre.space/t/new-users-welcome/29/278 feel free to also hang-around over our IRC channels at the freenode server #satnogs Matrix bridged here https://riot.im/app/#/room/#satnogs:matrix.org or #librespace Matrix bridge https://riot.im/app/#/room/#librespace:matrix.org
