Space Mission Acronym List and Hyperlink Guide

(W through X)

NOTICE: Because this original page had grown so large (~168K), I have split it into 14 pages, including this page for mission acronyms beginning with W and X. Some direct, named links will no longer work. If you are looking for information about a particular mission, please select the appropriate file from the following alphabetical listing. If you cannot find information on the mission you are looking for, you may find some information in the General Information page.

Created September 19, 1996. Last update: May 12, 1997 (additional, minor updates as late as July 26, 2000). Due to changing job assignments, I no longer actively maintain this page, and no one has taken over. I will continue to correct problems on a best effort basis.
