Abstract: In order to make a better plan for China′s scientific exploration for Jovian system，the development status of foreign Jovian system exploration missions were investigated and analyzed.Among the nine space missions that explored Jupiter and its satellites so far，seven are flyby missions.The other two are Galileo and Juno particularly for Jupiter.The Scientific goals，payloads configuration and exploration results were extracted and generalized.The mission characteristics and enlightenment of scientific exploration for Jovian system were obtained.Finally，on the basis of the above analysis and pending problems，the primary mission layout and prospect of scientific exploration for Jovian system in China were proposed.

Key words: Jovian , system；scientific exploration；scientific goals；payloads configuration；flyby exploration；orbiting exploration
