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 |

I have a xerox of an article from some journal like a major pub of the Geological Society of America or some such from the early 60's... maybe 1964 or 3. It's a carefully considered review of geological possibilities to look for during the exploration of Mars. It's thoughtful, well reasoned, raised essential questions regarding the possibility of finding folded mountain belts, volcanic features, erosional patterns.... etc. It totally missed the possibility of impact craters and the possibility of large areas with terrains that resulted from having minimal internal geologic activity for the majority of the planet's lifetime.
The overwhelming science results from Mariner 4 boiled down to three items. 1.) Some of the surface is REALLY old with lunar like cratering, probably impact craters. (whatever really old is). 2.) The surface pressure is confirmed by occultation to be at about 1/200'th atmosphere, as suggested by recent spectroscopy, and not the 1/10'th atmosphere most recent analyses had suggested the last couple <?> decades. Accordingly, the atmosphere must be mostly CO2 (enough to explain the spectra) 3.) There is minimal if any global magnetic field and thus no radiation belts. Thus the core is not molten or not driven to provide an active dynamo. Pretty impressive results for such an early mission. |
