TRICOM-1R was a re-flight of the TRICOM-1 CubeSat. On 14 January 2017 at 23:33 UTC (08:33 JST), the
SS-520-4 three-stage orbital rocket was launched from
Uchinoura Space Center carrying TRICOM-1. 20 seconds after launch, contact was lost with the telemetry transmitter on board the rocket, and the command to ignite the second stage was not sent. The rocket then flew in a
sub-orbital trajectory, reaching a maximum altitude of approximately . TRICOM-1 is believed to have crashed into the
Pacific Ocean with its launcher. Despite loss of telemetry from the rocket, the satellite was automatically released from the rocket around the time it was scheduled to, and ground stations were able to briefly receive telemetry from the satellite. ==See also==
