The solar system is a happening place this week! I just learned of a major storm in Saturn's northern hemisphere, being monitored by the usual band of talented amateurs. See this site for a list of recent images. Chris Go's site has a particularly nice image.

I hate to ask this question, but I'm really curious. If Cassini had a scan platform, would on-demand retargeting be a lot more feasible? I'm thinking, yes, we'd simply be trading off imaging vs. imaging, not imaging vs. the whole suite. But I don't know enough about the sequencing. Would a spacecraft with a scan platform have a separate sequence for the scan platform that could be modified by itself?

QUOTE (stevesliva @ Dec 16 2010, 07:55 PM)  I hate to ask this question, but I'm really curious. If Cassini had a scan platform, would on-demand retargeting be a lot more feasible? It would certainly be simpler, but nothing in spacecraft operations is simple. There would still be numerous issues to be resolved- what pre-planned observations would be displaced, where would the data be put and when would they be downloaded, thermal implications of the new scan platform orientation would have to be checked, and new command sequences would have to be developed and tested. The Mars Rovers are always responding to new information on ~24 hour timescales, but they and their operations are designed from the ground up to be able to do that. Orbital missions are never that flexible. John |
