> Here an alternative and novel mission concept is analyzed to return a sample from either Titan or Enceladus, without capturing at Saturn. Instead, ballistic free return trajectories are sought which also incur a close encounter of the icy moon. The spacecraft could sample a plume (or upper atmosphere) during the hyperbolic flyby.
The time frames are on the order of 20 years.
OTOH, you would only have a few dozen hours near the planet. ("This 16 year mission, has the Titan flyby occurring about 10 hours prior to Saturn closest approach").
I'm skeptical that it's worth it... because higher powered radios just aren't that expensive, but it's not obviously (to me) impossible either.
Actually capturing your probe back in earth orbit... probably would be prohibitively expensive. But it seems like you could at least get it close by for a shorter communication distance.
