- Who coined the phrase Rapid Unscheduled Disassembly?
Usually simply abbreviated as a RUD, and also sometimes expanded as Rapid Unplanned Disassembly, and being a way of understating that a rocket exploded I saw it attributed recently to Elon Musk, but although he has popularized the phrase among the public, when he mentioned it once in a speech I saw he simply said it is how the engineers on the

- launch - What exactly makes Red Dragon costly - Space Exploration Stack . . .
Except for its enormous amount of ambition and its relatively large risk of failure (e g Falcon Heavy RUD, a SuperDraco failure on Mars, mixing imperial and metrical units etc ), it seems to be relatively straightforward: Stuff Dragon II with enough fuel for re-entry and landing; Put onto Falcon Heavy; Aim and shoot
- How does a modern day satellite fall apart in space?
This generic question is answerable They blow up, aka rapid unplanned disassembly (RUD) but due to a large number of causes Or parts fail slowly and the vehicle eventually loses structural integrity There are lots and lots of things that can go wrong on objects in space
- Why was the SpaceX abort test not initiated by real booster failure?
Often the RUD comes later (see the Soyuz inflight abort - issue, followed by escape, followed by issue escalating into RUD) This would cover anything from a pump failing, engine gimbaling failing, unplanned engine shutdown, inability to stage etc etc etc $\endgroup$
- Super Heavy explosion, how much TNT equivalent would that be?
How does this compare to the N1 RUD's and to other non-nuclear explosions? Please assume the current specifications If not enough information is available, please keep this question open at least until Sep 28, 2019
- What is the advantage of doing a static test fire before launch?
But with the payload in place, RUD during the test fire is hardly a better outcome than RUD during launch I would also expect there to be at least some "bad luck" failure modes that occur only rarely, and are difficult to detect before they do occur (meaning that a test fire before launch effectively just doubles the risk of those failure modes)
- Did Starship Ship 25 burn up on re-entry? - Space Exploration Stack . . .
SpaceX Starship Ship 25 launched and managed a successful separation from the booster and reportedly made it into space before the autonomous flight termination system activated, destroying the veh
