It appears a programming error might have caused the scrub of Japan’s new Epsilon rocket launch yesterday.
The computer controlling the launch from the ground detected an abnormality in the rocket position but it was later found to be normal. “It may have been an elementary, but not serious, problem, ” said one of the experts, quoted by the Kyodo News agency. An inspection after the canceled launch found no abnormality with the attitude sensors mounted on the rocket or with the computer feeding the data to the ground, according to the Japan Aerospace Exploration Agency (JAXA).
This is a preliminary report, but sounds credible. The report also suggests that the Japanese are in no immediate hurry to launch but instead want to very carefully investigate the issue first. And as I said yesterday, this is really all good news for this new rocket.
