During the course of the Mariner 10 mission to
Mercury special Status Bulletins were published by the Mariner Venus/Mercury
1973 Project Office. These bulletins serve as a valuable guide to the
day-to-day events during the long cruise and the encounters. The bulletins
reproduced below in Adobe Acrobat format were scanned by Annie Bennett
and Jana Ruhlman at the USGS, Astrogeology
Branch, Flagstaff.
