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 |

The same thing almost happened to Voyager, if the BBC documentary series 'The Planets', was accurate in its description of the 'one man' fight to have the moons included as imaging targets for Voyager. Supposedly until the Io pictures came in the mission team was entirely composed of Atmospheric and Astrophysics specialists ready to unravel the mysteries of the Jovian atmosphere... Very early in the planning stage (about 1972/73) MJS 77 got cameras with Mariner 10 heritage. This has not been easy (budget etc.) and I guess this is the "dramatic fight" in The Planets. The moons have been a primary science target at least since then. JPL studied many trajectories and could only get close encounters with three moons at Jupiter. At Saturn, Titan has been a so high priority, Voyager 2 could be sent to it again if Voyager 1 failed. As for Juno: Its not about images first, not even second. It's not a sexy mission imo, but we will learn at lot. Analyst |

At Saturn, Titan has been a so high priority, Voyager 2 could be sent to it again if Voyager 1 failed. I've watched the relevant episode again ('Terra Firma') and it's definitely implied that the argument was not about having cameras on Voyager, but about where they were going to be pointed when Voyager reached Jupiter. As for Juno: Its not about images first, not even second. It's not a sexy mission imo, but we will learn at lot. You're absolutely right there, this is the sort of 'basic science' mission that needs to be carried out so that we can plan properly for the next major mission without any more incidents like dropping the atmosphere probe into the wrong region as happened with the Galileo's mission. And its been a long time in coming, this sort of mission was first proposed by the designers of Pioneer 10/11, even before the first flyby of Jupiter. In that case they planned to use an 'up-rated' version of Pioneer 10/11 to carry out long term (2 yr) observations of Jupiter (or Saturn) during the late 70's/early 80's. In these craft as with Juno, particles and fields studies would have been the main objective while imaging would have taken the back seat, despite the replacement of the Imaging Photopolarimeter with a 'line scanning' imager which would have presumably produced better images. |
