The Kounotori8 is claimed to be the 'the world's biggest transport space ship' by Japan's space agency JAXA.

The launch was completed successfully and as planned, the payload separated from the launch vehicle, about 15 minutes later, stated MHI. The unpiloted cargo ship carried more than 4 tons of supplies, batteries, and a prototype laser-communications system, according to reports. MHI is reportedly the prime contractor for the Japanese H-IIB rocket. The launch was successful in its first liftoff attempt itself - a month after its delay due to a fire in the launchpad.

Sept 10 initial launch cancelled

According to international reports, the earlier launch on September 11 was cancelled after a fire broke out on the launch platform a few hours before launch. Reports quote MHI saying that the fire had likely occurred due to static electricity generated when liquid oxygen from the rocket came into contact with heat-resistant material on the launchpad. MHI had reportedly stated that the material has now been covered with aluminum sheets to prevent a recurrence. MHI added that on the scheduled launch day, there were unusually low winds at Tanegashima, which complicated the launch.
