Space One, hoping to become the first private Japanese firm to put a satellite in space, said that what went wrong was "under investigation". TV footage showed the Kairos rocket blasting off from the launch site in the coastal Wakayama region of western Japan at 11:10 am (0210 GMT) up into the blue sky.

But shortly afterwards, the slim, white 18-metre (60-foot) rocket appeared to run out of power and head back downwards in a spin. "We determined that mission success was difficult and implemented flight termination measures," Tokyo-based Space One posted on X. It was unclear where it landed. The rocket was carrying several satellites including one for a high school in Tokyo, according to the firm. The company's first launch attempt ended in spectacular failure in March 2024 when the solid-fuel rocket exploded seconds after lift-off. A second try started off better only for the rocket to suddenly spiral downwards after engineers terminated the operation because of a technical problem. The latest launch had been slated to happen on Wednesday, only to be cancelled due to another glitch just 28.9 seconds before lift-off. (Bssnews)
