Below is a list of Medium-class EXplorer (MIDEX) series satellites, including launch dates and links to information on the satellites. If readers know of additional information, please contact the authors using the e-mail addresses at the bottom of this page.


Since all MIDEX-series satellites have other names as well, launch covers and other postal items for these satellites are found under those other names.
