I remember the "unscheduled disassembly" of a SpaceX rocket after launch a year or two ago. Only that didn't come from a news copy desk, it came from the SpaceX spokesflacks themselves.The exact line from USA Today is:
Let's see if it will hold together today. Launch is scheduled for 9:20 AM EDTI remember the "unscheduled disassembly" of a SpaceX rocket after launch a year or two ago. Only that didn't come from a news copy desk, it came from the SpaceX spokesflacks themselves.
Every profession has it's own lingo, often euphemistic. Somewhere along the line prison and jail guards became "corrections officers." (Sounds like a group of proofreaders. Inmate slang for them in some places was "screws.") Prisons became correctional institutions and jails detention facilities.I wonder if it was due to suboptimal quality control or performance limiting design factors.

I like that! *copies phrase* Now if I can find something in my life that I can use that excuse‘performance limiting design factor’
It makes it sound like the rocket had been talking to Marvin the Paranoid Android, and just given up."The rocket terminated the flight after judging that the achievement of its mission would be difficult," company president Masakazu Toyoda said. That's from the recent SpaceX attempted launch by a private company in Japan. The innuendo that the rocket terminated the launch because the mission was hard is laughable. Why didn't they just admit the truth, the damn thing blew the hell up, and we don't get a hint of a clue as to why?
Allowing for some language differences and understatement, I'd interpret that statement as what @cdstefi said: the rocket was veering off course, it was clear the launch had failed, so it was intentionally blown up either by remote command or by some automatic fail-safe process."The rocket terminated the flight after judging that the achievement of its mission would be difficult," company president Masakazu Toyoda said.

This happens quite often. A rocket that loses control for some reason is extremely dangerous. You can't shut off a solid-fuel engine once it's lit, and a rocket built to reach orbit can go a long way from the launch site before hitting the ground and exploding any remaining fuel. Worst case for this particular one, it flies into North Korea and gets interpreted as an attack.
Best mitigation for that is to blow them up in mid-air, letting as much as possible of the energy dissipate in the air rather than on the ground, near the launch site which hopefully is not near populated areas.
Why did Space One's Kairos rocket explode?
The small, solid-fuel rocket was designed to self-destruct when it detects errors that could trigger a crash and put people on the ground at risk.
However, it was not immediately clear what caused Wednesday's explosion and company officials have not specified what triggered Kairos to abort the mission so early into its launch.
:
Speaking to reporters at a Wednesday news conference, Space One Director Mamoru Endo declined to specify why company officials believe the rocket triggered its self-destruction after the first-stage engine ignited. An investigation into the malfunction is underway, Masakazu Toyoda, the company’s president, told reporters.
They got all mission goals accomplished, now they need to stick the landingThough today they did get a successful launch. If, at first, you don't succeed, spend a couple of billion more and see what happens.
So which "joint" do you work for? Is it municipal, county, state, or Federal level?I have to change my job title on LinkedIn...
Don't think asbestos had anything to do with it. It was rubber O-rings that got too brittle when it got too cold. They did too many cold launches, but only compared defect events amongst that cluster of launches, and couldn't see a pattern.FWIW, I was told by an insider that Challenger was brought down by a ‘performance limiting design factor’ when the asbestos O-rings were replaced with non-asbestos.

It was only when a young graduate said, why don't you compare ALL defects from ALL launches, including the hot weather ones? that it become obvious. Failures only occurred below a certain temperature. You gotta take a wider sample!
Correct. I had a fascinating book written about the whole thing, which went into the change in mindset that went on - written by a behavioural psychologist from memory - I loaned the book to someone, and no longer have it.Part of the tragedy is that some folk in NASA knew exactly what had gone wrong, they knew the O-rings weren't safe in cold weather, but risked being fired if they spoke openly. Sally Ride passed a report on to Donald Kutyna, who nudged Richard Feynman (Nobel-winner, independent member of the Commission, bongo drums player) and planted some seeds that got Feynman to rediscover the O-ring problem for himself, and Feynman could then publicise it (which he did very effectively). It was only afterwards that Feynman realised he'd been steered towards that discovery.

In essence, the engineers were asked to say, "It's not safe to launch" versus "It's safe to launch", which is a complete reversal of the question and of the mindset.
The most fascinating thing for me is that the engineers only deeply investigated those launches where they had detected issues. It wasn't until a young non-engineer came along and said "But you're not looking at EVERY launch, only those that leaked." When you see every launch plotted out on a temperature graph, the problem leaps off the page. Only those launches below a certain temperature showed leaks, but if you can't see the "no problem" high temperature launches, there's no obvious pattern down the bottom of the chart.
