jupiter, seen hst

the exploration of jupiter has consisted solely of number of automated nasa spacecraft visiting planet since 1973. large majority of missions have been flybys , in detailed observations taken without probe landing or entering orbit; such in pioneer , voyager programs. galileo , juno spacecraft spacecraft have entered planet s orbit. jupiter believed have relatively small rocky core , no real solid surface, landing mission impossible.

reaching jupiter earth requires delta-v of 9.2 km/s, comparable 9.7 km/s delta-v needed reach low earth orbit. fortunately, gravity assists through planetary flybys can used reduce energy required @ launch reach jupiter, albeit @ cost of longer flight duration.

jupiter has 69 known moons, many of have relatively little known information them.
