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 recall reading about that proposed orbiter. I vaguely remember Dr James Van Allen being one of the proponents of it.
Basically Galileo was a hybrid space vehicle in order to do both spining (which is better for the particles and fields instruments) and a stable (better for imaging) platform. And after all the suffering involved in engineering it, a lot of those involved swore they would never try another dual-spin spacecraft again. Cassini was supposed to be the "cheaper' vehicle... although it seems to me that at 3 billion dollars it ended up more expensive. Difficult to be sure, since Cassini was developed later and hence with inflated dollars compared to Galileo. Also, the antenna failure on Galileo introduced a lot of extra operations expenses, on a program that already was delayed several times, and redesigned a few times. I don't think I've ever seen a final tally on Galileo's costs, but I'm pretty sure it ultimately went over 2 Billion. |
