I thought that it was time to start a new thread devoted to the JUNO Jupiter
Orbiter mission. This New Frontiers Mission #2 seems to be a "stealth" project
with little information available on the Web. In fact, the official NASA JUNO
web site is quite pitiful. It contains the minimal amount of information on what
seems to be an intriguing mission, in terms of both science and engineering.

Does the UMSF community have information on this mission that has not
been widely seen before?

JRehling, I think that sensing several bulges moving around Jupiter is actually a three dimentional problem (or at least two, if we assume a symmetry regarding the equatorial plane).



mcaplinger, in fact you reply my previous question: "is Juno position measurement accurate enough to sense high ranking harmonics and detect tidal effects?". After your reply, it is not, and by several order of magnitude.


detecting only the first three harmonics will only allow to sense the inner spherical layer structure, and even not very accurately. No hope to detect vortexes or other exotic things.

To achieve a better accuracy would require that Juno sense three pulsars with a high accuracy, or three natural masers. But I am afraid that this would involve very large antennas, much too large for a ship like Juno.


The only practical solution would be to have a kind of GPS positioning around Jupiter.

I already said several times in this forum that a GPS positioning and radio relay (with large data storage) would be one of the first things to do for seriously exploring any planet. Such small satellites would be designed to last for tens of years, for further missions.

On Jupiter, this is especially difficult, with the radiation belts. But could be a ship like Juno be left in orbit, once it exhausted its fuel, and be used as such a relay? This would just require some tens of kilos of additional mass, and be very useful for further missions.
