Title: List of Acronyms used in Space Flight
Post by: pagheca on 05/22/2014 01:00 AM
I created a document (see attachment) listing all acronyms used in space flight. The list is still 99.9% a cut & past from the NASA Acronym list (http://spaceflight.nasa.gov/shuttle/reference/acronyms/). However, many acronyms currently used in this blog and elsewhere are not yet included.

I will keep it updated by asking people to supply a translation of any acronym used in a post.You can even add by posting here.

I will update the document time by time and attach the latest version to this post.

Please write me or post in the thread if you have any suggestion or

cheers,
pagheca

Well that's amazing work!

We'll make this thread sticky at the top after everyone has seen it on the normal listing! :)

 I guess two of the most common NSF ones, RUD and BFR aren't "official" NASA acronyms.

My aim is to supply a list to be used by people that, like me, is not directly involved in this business and find hard to understand a lot of posts here.

So, what those RUD and BFR means?

@Chris et al.: thanks, but I'm not happy with it. I couldn't find a way to make it easier to manage. The document is bulky and even a simple search may be difficult.

Any idea???

RUD is used when your test winds up strewn across the landscape. Explosion is such an unpleasant term, they call it a "Rapid Unplanned Disassembly"
 BFR is a term to describe a huge vaguely defined rocket.
 Both, obviously unofficial terms.

Then there are a few that are unofficial, to an individual/crew level or ones used by the public...
SOL comes to mind.  :o Heard that one at Ellington a while back. Also heard someone at NASA use that in reference to Lisa Nowak just before NASA and the Navy booted her.
Also, I've heard DT, meaning 'Deceleration Trauma' to mean someone smacking the earth at a high rate of speed from above (as in, "Man, that ol' boy's chute didn't open. Go grab a mop, man!").

Please, I really appreciate your comments, but remember to add the acronym explanation!!!

What does SOL and BFR means exactly? I mean something like Bxxxx  Fxxxxx Rxxx

Thanks again for your time. I'm updating the paper as I read, but it's really a nightmare! This site has a production rate for acronym that would overcome the capability of 10 human being working full time on that! :)

Edit/Lar: B R F->BFR

Someone can correct me if I'm wrong, but in the only context in which I've run across SOL, it means S*** Outta Luck, the S*** usage the same as in "Same s***, different day."

In this context, SOL would be used as follows:  "He thought he would be able to get through his task list today, but what with the subcontractors going out on strike, he was SOL."

Well, yeah, you didn't read the line I wrote right above that to explain it, apparently.  ???
It is a common-use term that IS indeed used by NASA. I've heard it more then once at Houston.

Used by a lot more people not in NASA.  I have heard many more others acronyms at NASA, but that does mean they are spaceflight related.  SOL is no different than FUBAR or SNAFU.  If you are going to include SOL, might as well include SOB, STFU, WTFO, MFWIC, etc.  Military slang does not equate to NASA or spaceflight slang.  Believe it or not Houston is not the center of the spaceflight universe.

ehm, while I agree that we probably shouldn't include the "racier" aspects of acro's and such I need to point out Jim that your statement:
Quote
Military slang does not equate to NASA or spaceflight slang

Is "applicably" not correct :) Military-speak and specifically the "slang" was present from the begining and tends to permeate the "language" used. I haven't looked over the list yet, but I'd be surprised if it actually included a few of the oft-used terms that derived directly from "mil-speak" such as SEMM, ("Steely-Eyed-Missile-Man" most times used to describe someone who got the job done under pressure, doing what it took to get it done, etc)

"Mil-Speak" acro's were hot and heavy from the start due to the Military's "influance" over and within NASA and rocket operations. And at times it was a direct "contest" on who's nominclature and designations would be used between "mil-speak" of the supervisors and techs and "geek-speak" of the scientists and researchers involved :)

Lest we forget the Mercury "capsule" was originally labled the "BPC" or "Biological Payload Container" even after the "man" replaced the "monkey" :)

My point was just because the military used it, does not mean it was used by spacecraft program workers.  There is some cross over but not the bulk of the military slang

My plan is to upload one update a month, and remove previous versions.

Please help me by posting here new acronyms with their explanation and the context (Apollo, SLS, ISS, etc...) where it is mainly used if any.

There are an endless number if you look into specific projects. However, here are some general ones which are missing:
ACT: attitude control thruster
AIT: Assembly, Integration and Test
AIV: Assembly, Integration and Verification
ECSS: European Cooperation for Space Standardization
SVT: system verification test
LEOP: launch and early orbit phase
SDB: satellite database
GNSS: global navigation satellite system
RO: radio occultation
RX: receiver
TX: transmitter
TC: telecommand
TM: telemetry
HPTC: high priority telecommand
OBCP: on-board control procedure
OGSE: optical ground support equipment
UQPSK: unsymmetrical quadrature phase shift keying

More next time. I've got loads but it takes an effort to think through what I know and check if it's general.

cheers,
Richard

Thanks a lot, RichardF! You are right: the number of acronyms in Space flight is almost infinite!!! (not just 26^x, for x reasonably large, as many of them have many different meanings...).

However, I think some of those in the list (AIT, AIV, RX, TX...) are really generic, and it maybe better not to add them to the list. (Yes: many in the original NASA list are generic too but filtering them would take too much time...)

LRD - stands for Landing and Recovery Division. This was abolished in 1972.

Not sure that Launch Recovery Division as listed is valid as the Landing and Recovery Division also prepared and had procedures for launch aborts.

The most exhaustive historical acronym list I've ever run across was one on a Czech site here:
<<http://www.lib.cas.cz/space.40/ACRONYMS/TACRON-0.HTM (http://www.lib.cas.cz/space.40/ACRONYMS/TACRON-0.HTM)>>

When I merged it into a list I already had and converted it to pdf it ended up being ~675 pages long.

Unfortunately the author seems to have stopped updating it in 2007.

I am not saying it wasn't used then (and was only used for a short while).  But it has been overshadowed for the last 35 years or more by the shuttle, it is Landing and Recovery Director.  And there are many more 'old timers' that worked in that.

http://science.ksc.nasa.gov/shuttle/countdown/lps/ab/ab.html

You got to let go of it.  Apollo existed for only 15 years and Saturn V had only 13 launches.  Only some facilities remain.  Its legacy is only in its accomplishments, its practices have been made OBE by the shuttle.   And actually, the real practices that remain are those done by the unmanned programs both launch vehicle and spacecraft, who have been chugging along since the early 60's.  The legacy of NRL and Bob Gray's Vanguard group along with the Air Force Atlas/Titan and Delta/Thor groups still lives on, unlike the Restone MFL and MSC spacecraft groups. 

You got to stop comparing everything to Apollo.  There has been a lot more happening since then.  The moon landing was a stunt.

What part do you disagree with? That there was an LRD for the shuttle or that there will be an Orion LRD? The shuttle LRD was responsible for the ground assets at all the landing sites (RTLS, AOA and TAL).

It's not me that's disagreeing. LRD (Landing and Recovery Division) is a valid acronym even if it is historic. My original post did say that it was abolished in 1972. By the same arguement as used by Jim, do we discard also FITH, FIDO, LOS and other acronyms from the Apollo era?

LRD is a valid acronym for Landing and Recovery Director, it was in use much longer and much more times as that so it is the primary definition. Landing and Recovery Division has now be relegated to a secondary or historical definition.

Yes,  we discard acronyms if they are no longer in use or if the original definition has changed.  The list here is for people to use going forward.  If there is a question about an acronym from the  past, it can go in the historical section.

I can't think why you're so intent on disagreeing with me on this. I've never suggested that Landing and Recovery Director wasn't a valid definition. All I've suggested that is that prior to 1972 a definition of Landing and Recovery Division was an equally good one also.

Let's leave it at that shall we? Or are you that determined to have the last word? Surely, in the context of this thread both should be listed.

the aim of my list was just to help not-particularly-informed readers like me to understand what particularly-informed writers say, as they usually use a huge number of acronyms and they do not care about explaining what even the most cryptics of them mean.

So, obsolete acronyms are welcome as well as news. Thanks.

Here are a few Apollo-era acronyms you don't have yet:

GCTA - Ground Commanded Television Assembly  (on the LRV, pronounced "gotcha")
LCRU - Lunar Communications Relay Unit  (on the LRV, pronounced "la-CREW")
LEVVA - Lunar Extra-Vehicular Visor Assembly  (Visors and sunshields worn over suit helmet)
SESC - Special Environmental Sample Container  (for collecting lunar samples w/associated gases)
SCB - Sample Collection Bag  (for putting small sample bags into, attached to side of PLSS)
LRRR - Lunar Ranging Retro-Reflector  (laser reflector, commonly called LR-cubed)

Just a few I notice you're missing...

While browsing elsewhere I was hung-up on "HEOMD" in several threads. It's missing from this grand list.

My Google-Fu was sufficient to discover that's NASA's "Human Exploration and Operations Mission Directorate," which apparently makes the short- to long-range mission planning timelines for HSF, both robotic and crew.
