> 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").
