A technical glitch prompted Japan's space agency to abort a mission to use a mini-rocket to send a satellite into orbit just seconds after liftoff on Sunday.
According to reports, the SS-520 rocket stopped sending data to ground control.
The spacecraft, which stands around the size of a power pole, lifted off at 8.33am into a clear sky at the Uchinoura Space Centre in southern Kagoshima Prefecture.
The rocket, regarded as one of the smallest units in the world capable of sending satellites into the space, was carrying the three-kilogramme (6.6 pound) "TRICOM-1" observation satellite.
But officials aborted the mission within minutes of takeoff after the space agency stopped receiving data from the rocket after the launch.
Local media said data stopped arriving 20 seconds after liftoff.
"The first stage of the rocket's flight went as planned. However, we were unable to receive from the unit as it continued the flight," the agency said in a statement.
The rocket later fell back to earth, landing within a designated safety area in waters off the coast of southeast Japan, according to officials. The country's space agency is expected to provide a more detailed debrief about the nature of the mishap as more information becomes available.
