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 |

A generic question about trajectories: does anybody in here know how to work the NAIF Spice Kernel tools/files (or whatever it's called ...) I think they would provide more accurate information for my realtime simulations than Horizons, but I just cant understand on how to work them. All I'd need is something to convert the SPK files into the good old 4 dimensions (x,z,y [wrt to solar system barycenter] and time). Feel free to send me a private message as well.
Thanks for your help in advance! -------------------- |

There's no reason that Horizons isn't just as accurate as it's probably just using the SPICE kernels internally anyway. And the orbit is going to be different than any available kernel anyway, based on the launch date and injection errors, TCMs, etc. -------------------- Disclaimer: This post is based on public information only.
