Japanese Smallsat Launcher Fails in Maiden Flight

The world’s smallest launch vehicle failed in its maiden launch from a Japanese spaceport on Sunday.

JAXA’s SS-520-4 booster took off from the >Uchinoura Space Center at 8:33 a.m. local time carrying the TRICOM-1 CubeSat. The space agency said although the rocket’s first stage fired normally, the second stage failed to ignite. The booster and its payload fell into the ocean.

The SS-520-4 is an upgraded version of a Japanese sounding rocket that is designed to launch micro-satellites. The three-stage booster stands only 9.5 meters (31.3 ft) tall and has a diameter of .52 meters (1.7 ft).

The TRICOM-1 spacecraft was developed by the University of Tokyo. The 3-kg (6.6 lb) CubeSat included store-and-forward communications equipment and Earth observation cameras.
