You should look into the more modern tooling available these days, like the Krita plugin and InvokeAI.
Sure, you still use a prompt in those, but it's not really the focus in many cases -- you just use it to give a very rough guideline of what you're trying to do, then start drawing.
Depending on approach you'd either start sketching your astronaut and see the AI turn the sketch into something polished in real time, or you'd generate an image then polish up the details. I think most artists are more likely to prefer the first approach.
