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.
