RUD - rapid unscheduled disassembly

[Delrey]

As stated by Elon regarding the failed landing last week. That acronym definitely has a place on and around kerbin

[Alshain]

No disrespect to Elon, but that acronym has been used in hobby rocketry for a long time. It's similar to a golfer yelling "fore" or a lumberjack yelling "timber". If you hear someone yelling it, you need to find cover.

[Delrey]

Never heard it

One presumes, in terms of spaceX last week, that this happened shortly after the booster underwent 'HydroBraking'.

Awesome name.

I think you meant HydraBraking. HAIL HYDRA

yes I blame hydra for last week

[StrandedonEarth]

I wasn't aware it was used in hobby rocketry (doesn't surprise me), but I do know Mr Musk was using it as far back as the initial Merlin 1a testing.

[DirtyHarry]

His last tweet (after sharing the photos from the "RUD" in question) was even more "Kerbalish":

Next rocket landing on drone ship in 2 to 3 weeks w way more hydraulic fluid. At least it shd explode for a diff reason.

You can't make this stuff up.

So, when people curse about their ruddy ships, this is where the term comes from. Example: "That ruddy rocket won't make it out of the atmosphere!"

"Ruddy" is now a more colloquial term used to describe general dissatisfaction about something. But when used to describe a space-craft, in particular, the term "ruddy" really indicates the person's opinion that it just might blow up at any time.

It originally derived from the acronym "R.U.D." which stands for "Rapid Unscheduled Dis-assembly." An RUD can occur for many reasons, not necessarily an explosion, although explosions are common for these incidents regarding space-craft. Another common cause of a RUD is descending too quickly, breaking up in reentry, or hitting the ground too hard from insufficient use of parachutes or controlled landings.

Thus, "ruddy" can be used to describe any general way that the speaker thinks the craft might fail. Lately, "rudding", "rudd'n", or "rut'n" can be heard in certain dialects, as variant adjectives to describe the same thing. E.g. "That ruddy ship..." or "That rudd'n ship..."

Right up there with "CATO," Catastrophe At Take Off, which refers mainly to various, er, "failings" on or near the launchpad.

[dryer_lint]

Let's not forget how the massive Antares explosion was first referred to as a "launch anomaly".

[RCgothic]

I prefer Rapid Unplanned Disassembly, but that's just a mater of taste.

[Boris_T_Roach]

When something has gone wrong on the launch pad, I've always thought of them as SMEF events

Ie My latest single stage to Jool rocket had a Spontaneous Massive Existence Failure because some moron started the SRBs and failed to notice the radial decouplers for the same were on the same stage.....

I've been saying yard sale which is what we say skiing when you eat $#!% and all your gear is scatter about the hill side

[Skorpychan]

http://www.planetary.org/blogs/jason-davis/2015/20140116-falcon9-rapid-unscheduled-disassembly.html is the best I could find with a (very) quick google search for spaceX.

Seems about right. Since he didn't really expect it to work ANYWAY, he can learn from the mistake and move on.

For knowing is half the battle.

[cptdavep]

I've also heard "reaching ocean synchronous orbit" which cracks me up every time.

Did anyone see SpaceX's vine of the actual crash they just put on twitter. That's a Run Like Hell moment!

Reminds me of most of my Tylo "landings"

Yes, that rolls off the tongue much more easily.

[Mistake Not…]

The Guardian's attributing the phrase to fans of Kerbal Space Program - so we should take the credit, regardless of any previous documented usage!

Yard sale is a lovely euphemism. Very fitting when your gear is strewn across a mountainside too.

[longbyte1]

You guys have it all wrong. Rapid unscheduled disassembly is usually part of a lithobraking maneuver.

Also may I remind you that if you see a bomb technician running, follow him.

I think this warrants a set of images demonstrating rocket failure euphemisms. Time to mine my screenshot folders, and take more for posterity.

[Yukon0009]

How about Laytheobraking?

[LameLefty]

RUD, lithobraking and others have been used in real-life aerospace for decades (I know we used them in the 90's in industry, and they were old terms even then). I expect they go back to the Cold Ward/Steely-Eyed Missile Man days.

I think we (KSP player base) stole them from the aerospace industry.

Single Stage Rockets don't have SRBs, and if they did, they wouldn't be able to detach.
