MAVEN Solar Wind Electron Analyzer seeks answers at microscopic levels

The MAVEN will find many answers to understand Mars. I think similar measurement for Venus would be interested too. Spacecrafts are supposedly to interfere (the measurement of) the interplanetary or upper atmospheric ions, electrons and their magnetic properties, the similar measurements (for example, at microscopic levels) for Jupiter (and Saturn) with their moons must be very complex. The results and properties among Venus, Jupiter (and their moons and Saturn) would be very different, and many new discoveries are expected ; while the MAVEN wants to find some important answers for Mars.
Recent instruments are becoming more powerful light weight smaller low cost robust lower consumption higher sensitivity higher storage higher sampling rate, and perhaps the exponentially growing software capability indirectly solving some important and difficult problems, then to measure these planets becomes possible.
