It appears a programming error might have caused the scrub of Japan’s new Epsilon rocket launch yesterday.
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.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

But the “computer” was supposed to take care of the “simple” stuff…
The computer DID take care of the “simple” stuff. It saw a potential problem, stopped the launch, and alerted the ground crew. It is much better to clear up any confusions before launch than during launch or during the mission. If only the Mars Climate Observer (AKA Mars Surveyor), the first Ariane 5 rocket (Ariane 501), etc. had discovered their problems in time to do something about it…
There was no REAL problem. It shut things down, when it sould have let it launch. So the computer was the problem…
It is SO much better to not launch because of a false positive than to launch because of a false negative.
This business still has plenty of maturing to do.
Getting into space is difficult, expensive, and dangerous. Out of control rockets can — and have — crash into inhabited towns. I greatly prefer a delayed launch to a lost payload or mission – or crew. I do not laugh at or mock a launch crew that plays it safe or over-sensitizes its computer programs. The alternatives turn out to be too expensive.
