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? Another Phil |

As discussed above, imaging with JunoCam is a peripheral goal for the mission. But Juno will be the first Jupiter probe to be placed into a polar orbit, and we are beginning to see the advantages of this orbital inclination from Cassini (Monster Storm).
Does anyone know JunoCam’s pointing direction and whether it will be able to ride along with any of the other instruments? The Juno team reports that primary science measurements are taken at ± 3 hours from perijove for all science orbits. Furthermore, only two science modes (and thus pointing directions) are necessary for the entire primary mission. These include radiometry and gravity science. Since the closest passes over Jupiter’s polar regions are included in the primary science windows, will the team allow JunoCam to image the poles during the mission, or is this something they will focus on late in the game? Can we expect similarly informative and stunning Jupiter polar images from Juno as we will get from Cassini? |

An obvious problem is that Jupiter's poles never get much sunlight due to Jupiter's low axial tilt (~3°). Compare this to Saturn's ~27°. Obviously the poles are not in darkness but they are more difficult to image and you cannot image a big around around the pole in a single image (or over a period of several minutes). Vertical relief is also less pronounced on Jupiter since the atmosphere is more 'compressed' than Saturn's.
