This is a re-delivery of the full mission SPK to fix issues discovered during the Proximity Operations phases of the previous file which were caused by converting the SPK type to a format accepted by the DSN. This version fixes those issues, but does now require the Bennu ephemeris to be loaded in order to determine the state for a portion of the trajectory. As with previous deliveries, this file is defined to start prior to SEP through SRC release for nominal Day 06 of the 39-day Launch Period of 2016, and is the open launch case for that day. The delivered trajectory files should be used with the DE424 planetary ephemeris and the small body Bennu ephemeris file sb-101955-76.bsp If you have any questions about this delivery, please don't hesitate to contact me via email and/or phone call.
