Here, in Icarus today...
http://arxiv.org/abs/1312.6554 Abstract QUOTE The solar wind electric sail is a novel propellantless space propulsion concept. According to numerical estimates, the electric sail can produce a large total impulse per propulsion system mass. Here we consider using a 0.5 N electric sail for boosting a 550 kg spacecraft to Uranus in less than 6 years. The spacecraft is a stack consisting of the electric sail module which is jettisoned at Saturn distance, a carrier module and a probe for Uranus atmospheric entry. The carrier module has a chemical propulsion ability for orbital corrections and it uses its antenna for picking up the probe's data transmission and later relaying it to Earth. The scientific output of the mission is similar to what the Galileo Probe did at Jupiter. Measurement of the chemical and isotope composition of the Uranian atmosphere can give key constraints for different formation theories of the solar system. A similar method could also be applied to other giant planets and Titan by using a fleet of more or less identical electric sail equipped probes. P |

Cassini Saturn-escape trajectories to Jupiter, Uranus, and Neptune Okutsu et al Fly-bys were not considered a viable alternative to orbital science at Saturn, IIRC. Especially since the flight time was 26 and 41 years to Uranus and Neptune. |
