This list includes in-orbit failures of Earth satellites only (with a few exceptions). Failures that occurred before a spacecraft was declared operational (i.e. during in-orbit testing, in transfer orbit etc.) are marked "IOT." Failures that occurred during manufacturing and testing on the ground are not included. Rocket launch failures can be found on a separate page. All dates and times UTC unless otherwise noted.
