According to page 7 of this PDF, Comet 67P/Churyumov-Gerasimenko, the target comet for Rosetta, will have a close encounter with Jupiter in 2018 (it has encountered Jupiter before in 1840 and 1959). Figure 4 on page 10 says the closest approach distance in 2018 is ~0.4 AU. Rosetta will be arriving at the comet in mid-2014 and will study it until at least December 2015. Obviously I'm wondering if it is at all possible for the probe ride the comet to Jupiter, remaining active (at least minimally with it's solar panels) until 2018 and doing some Jupiter observations during the close approach? Or perhaps if enough fuel remains, after the nominal mission ends in December 2015, it could escape the comet and adjust its trajectory for a flyby at Jupiter and/or one of it's moons?

"A bit", lol. 4 microns +/- 44 microns is zero is layman's terms. The mystery continues...
