I was building a rocket to go really close to the sun, and I wanted to be able to keep my heat sheild pointed derectly at the sun in order for my cooling panels on the rear to work properly. its a simple thing, but I think this would be super useful for crafts stuying the sun.
Okay, stupid me. I didn't realize pitch and yaw were correlated to the relative body, so a sun orbit craft would be facing the sun at pitch -90...
