I recently saw a really good KSP video titled KSP: Far Future Mission To Saturn [RSS/RO] (please go sub to the person who made it and watch the video it’s soooooooo good) and upon return from Titan, they used a VentureStar-style vehicle, but didn’t use engines to reach orbit and dock with the transfer vehicle, they used a huge balloon to ascend as high as they could, and then accelerated with engines to orbit, etc. I think that’d be super cool for low-gravity, high atmospheric density bodies like Taurus and Nebra. Maybe they could have a radius and height arrow for resizing instead of preset uneditable sizes? Idk, but it’d be heccin’ fun to play around with!
