NASA's Explorer Missions |
 | | NASA's Explorer spacecraft series is not simply the longest running series of spacecraft, it has produced highly-durable (i.e., well-engineered) spacecraft as well. |
 | | Of the 73 successful Explorer missions depicted, fully five of them had had missions which lasted 10 or more years, the longest of which (IMP 8) has been operational for over 26 years now and still produces valuable information about the solar wind. |
