Excerpt from Cassini Significant Events for 02/16/06 - 02/22/06:
"As mentioned in previous weeks, the project has been working on adopting a new reference trajectory in order to raise the minimum Titan flyby altitude for various encounters. Today the project reached a decision to proceed with the 'optocc2' trajectory. Additional work is still to be performed before delivery of the final files. This will include minor tweaks that have been analyzed in other trajectories, adjusting orbit 68 timing, and capture of an Enceladus plume occultation on orbit 28." For the record, the new reference trajectory will result in an even more spectacular Enceladus-3 flyby [61EN (t) E3] on March 12, 2008. |

I think this is the highest resolution image taken of Enceladus so far:
NAC: http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=45681 WAC: http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=45711 As you can see the narrow angle image seems to have motion blur - from an altitude of 545km. |

According to the Photojournal page, the surface imaged here was actually just 319 km distant, a side-looking shot taken while Cassini was 208 km above the surface. http://photojournal.jpl.nasa.gov/catalog/PIA06252 This is 4 m /pixel, indicating that were it not for blur, imagery from a range of 25 km (which isn't going to happen if C/A is on the nightside, among other reasons), would have a resolution of 31 cm (one foot for Standard fans). |
