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 far as I can tell, the Juno team has always planned to include X-band radio frequency capabilities. Does the addition of the Italian Ka-band transponder add a new dimension to the gravity science experiment, or has NASA just outsourced development of that instrument to Italy?
In more general terms, there are a multitude of radio frequencies available for gravity science. Do most space agencies choose X and Ka-bands because of their extensive communications development and because they both just pass through the atmospheric radio frequency window, or are there additional reasons? [Ka-band seems to be the shortest wavelength to still transmit through the atmosphere.] Finally, are Doppler shifts measured concurrently for both frequency bands to achieve signal redundancy, or can we actually improve signal to noise rations with a combined analysis (or something like that)? I’m really looking forward for this bird to get off the ground. |
