Astronomical/telescope
satellites


Below are checklists of Astronomical/telescope satellites, including launch dates and images of the satellites. This is a work in progress, and completeness is our goal. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

Note: Astronomical/telescope satellites (such as Explorer-38/49 / RAE, Explorer-42/48/53 / SAS, and Explorer-74 / SWAS) that are part of larger mostly non-astronomical series (in these examples they are part of the long Explorer-series) are listed only as part of that larger series. In other words, in such cases their entries are not repeated in this page.
