The latest version and other formats (e.g. ASCII text) of all documents       
for the Deep Impact and EPOXI missions are available in the Deep Impact       
and EPOXI documentation dataset, DI-C-HRII/HRIV/MRI/ITS-6-DOC-SET-V4.0,       
available online at http://pds.nasa.gov.  However, several of the most        
useful documents are duplicated here in PDF/A format for convenience.
