    SpaceX = Space Exploration Technologies, Inc.
    List of Falcon 9 and Falcon Heavy launches - Wikipedia

    ASDS = autonomous spaceport drone ship
    Autonomous spaceport drone ship - Wikipedia, the free encyclopedia
    JRtI = Just Read the Instructions, the first of the ASDS fleet. Rebuilt and moved to West Coast.
    OCISLY = Of Course I Still Love You, the name of one of those ships, stationed in Florida.
    The names come from sentient ships in Iain M. Banks' Culture series of Sci-Fi novels.
    Mr. Steven = Newest ship used to recover the fairings

    SES = a particular satellite company SES - Global Satellite Services Provider - Your Satellite Company - SES.com

    NROL = National Reconnaissance Office Launch

    CRS = Commercial Resupply Services, the name of the program to resupply the ISS. SpaceX won this bid from NASA who pays them to deliver goods to the International Space Station (ISS). This is an official series of missions for SpaceX that will take place over a number of years.
    Commercial Resupply Services - Wikipedia, the free encyclopedia

    You'll also be hearing a lot about:
    Commercial Crew Development - Wikipedia, the free encyclopedia
    CCDev
    CCtCap

    Various types of orbits have different shortcuts as well:
    Orbit - Wikipedia, the free encyclopedia
    LEO = Low Earth Orbit
    GTO = Geostationary Transfer Orbit - A much harder to reach orbit, highly elliptical. Used to get to GEO.
    GEO = Geostationary Orbit, where the orbit takes 24 hours so the satellite appears stationary over a place. Always above the equator.

    SpaceX rocket terminology:
    Falcon, Falcon 1 = the original two stage, two engine rocket.
    Falcon 9 = F9 = SpaceX current rocket using Merlin 1D engines.
    Falcon Heavy = FH = SpaceX new heavy lifting rocket due out for testing by the end of this year (2016). SpaceX has already got orders to use this three core rocket.
    Dragon, Dragon 2 = capsules to go to the International Space Station, the latter being man-rated.
    FT = Full Thrust = The new designation for the Falcon rockets using the newest technology. The fuel is "superchilled" to allow for more fuel and more efficiency, and slightly enlarged tanks.
    Block 5 = A design designation. This is supposed to be the finalized design of the F9 with all of the updates learned from recovering boosters. It is designed for multiple reuses with little turnaround time.
    Core = Booster, first stage of F9; Falcon Heavy has three cores.
    Fairings = Two piece aerodynamic covers on the top of the rocket. They protect the payload in atmosphere and are discarded soon after MECO. SpaceX is attempting to recover these very expensive pieces.
    FPV = Flight Proven Vehicle = re-use of a booster or Dragon capsule.
    Octaweb = structure that holds the nine motors of the F9 (eight in a circle, one in center)
    BFR: Big ...ummm... Rocket, proposed successor to the current line. Previously referred to as MCT (Mars Colonial Transporter) and more recently, as ITS (Interplanetary Transport System).
    BFR: Now officially called Big Falcon Rocket. Formally introduced at the 2017 IAC. This name can be used for the overall system or just the booster since the second stage is called the:
    BFS: Big Falcon Ship. A multi-purpose smaller version of the ITS second stage. Is intended to be used for all space operations.

    Engines:
    Merlin, Merlin 1D (current version), nine in the core.
    Merlin 1D-Vac, one motor in the second stage, optimized for operation in vacuum.
    Raptor, proposed new motor for the proposed "BFR". It is a methalox engine and uses a Full Flow Staged Combustion cycle.
    Draco, hypergolic-fueled thruster used on early versions of Falcon 9/Dragon.
    SuperDraco, hypergolic-fueled thruster used for abort and soft landing of Dragon 2.
    Keralox: the Merlin motors burn RP1 (kerosine) and LOX (liquified Oxygen).
    Methalox: Raptor motors will burn liquid Methane and LOX.
    Hypergolic: two chemicals that ignite spontaneously when mixed. In this case, Monomethyl Hydrazine and Nitrogen Tetroxide.

    Places:
    Hawthorne, CA: headquarters, manufacturing. Other R&D in Palo Alto, CA, and Redmond, WA.
    McGregor, TX: Test firing and site of the old "Grasshopper" launches. The Raptor engine is being developed here.
    Boca Chica (near Brownsville) TX: Private spaceport under construction
    SLC-40 = Space Launch Complex 40 = The name of one of the launch facilities at Cape Canaveral that SpaceX uses. This pad is used for only Falcon 9 launches.
    LC-39A (historic pad for launching Apollo and Space Shuttle missions) Used for Falcon 9, Falcon Heavy, and Crew launches.
    Vandenberg, CA: Air force base, used for launching to high-inclination orbits (can launch to south).

    SpaceX

    Competitors:
    ULA = United Launch Alliance = A company combining Boeing and Lockheed-Martin rocket manufacturing. They use the Atlas V rocket which uses the Russian RD-180 engine. They also use the Delta IV rocket. Their upcoming rocket will be called Vulcan and will likely use a BO engine.
    CST-100 = Boeing makes this capsule for ferrying astronauts to the ISS in the CCtCap program.
    Orbital ATK = Makes the Cygnus cargo capsule for ferrying supplies to the ISS.
    Blue Origin = space tourism venture backed by Amazon's Bezos. Also designing new rocket motors for NASA and ULA.
    Virgin Galactic = space tourism venture backed by Virgin's Branson. Air-launched space planes.
    Roscosmos = Russia's launch company, currently the only way to launch people to the International Space Station. Launch from Baikonur in Kazakhstan.
    Arianespace = French launch company, gets lots of European Space Agency business. Spaceport in Guyana.
    CNSA = Chinese National Space Agency. Also provides commercial launch services.
    A number of other countries have launched satellites, but don't provide launches for third parties.
    SLS = Space Launch System. The heavy launch rocket funded by Congress and overseen by NASA. It uses old Space Shuttle engines and has eaten up over $20 billion in funding if you include the large capsule Orion. This rocket has never flown. A test article Orion was launched on a Delta IV and was recovered. The first launch is tentatively scheduled for 2019.

    I apologize for my ignorance in advance, but I love to pop into these threads and read about what is going on with SpaceX. Only problem is I don't know the lingo.

    I was wondering if you guys could set up a glossary of sorts, maybe above all the threads, that us noobs could click on and figure out what ASDS, SES, OCISLY etc... may stand for.

    As you can guess I am not a rocket scientist, nor do I pretend to be. Just a humble request. Thanks in advance!

    Thanks Doug and Grendal. I'm familiar with most of this information, but you guys have filled in some interesting gaps. The reference lists and acronym explanations are useful to help follow this thread on SpaceX.... JRTI! ;-)

    That's usually written JRtI, as it would be capitalized if written out.

    Also @Grendal, it's Full Thrust, not Full Throttle. The turbopumps move as much as they can, it's just that there's less of it if it isn't chilled. The "throttle" was always wide open. Except when throttling back for MaxQ (Maximum aerodynamic pressure).

    Octaweb - the support structure and plumbing used to attach the 9 Merlin engines to the rest of the first stage of the Falcon 9 v1.1 or Falcon 9 FT rocket. Sometimes the term is used to refer to the engines as well, once they are mounted on the rocket. The new pattern of 8 engines circularly arranged around a center engine is different than the original Falcon 9 v1.0 layout, where engines were in a 3x3 square grid pattern.

    For what it's worth, I'm the maintainer of the acronym expansion bot (Decronym) for Reddit's SpaceX community, so there's a fairly comprehensive list of acronyms here: Decronym

    Some of the expansions link to Wikipedia articles or (in one case) YouTube videos on the subject, but more links and more detail are always welcome.

    Isn't SpaceX short for space exploration technologies?

    Wow, thanks for that. Seems like a viable system for getting things done and having short words for spacex. The competitors are going to be shocked when spacex goes to mars and lands humans there first!

    Since we now have a bunch of used boosters. I believe SpaceX has designated them by their flights instead of their payload. So:

    F9-0020 was the first landed booster. It's on display outside the factory.
    F9-0023 was the first ASDS booster.
    F9-0024 was the max damage booster. It is being thoroughly tested and will not be re-flown.
    F9-0025 was the tilting booster.
    F9-0027 was the second RTLS booster.
    F9-0028 was the single engine burn GTO booster.

    And so on into the future. I expect a Falcon Heavy core will use an FH- designation.

    This is partially correct. SpaceX assigns two numbers - a four-digit production ID number, and a four-digit number assigned between production and flight. The former is used by everyone on the line.

    However, many of the production ID numbers are not public. Those that are can be found at this page (which is a pretty handy resource) --> reddit.com/r/spacex/wiki/cores <--

    I realize this isn't about SpaceX, but I'm hoping it's okay with everyone since it does have an impact on SpaceX and space. This is something that NASA puts out every year that documents 50 technologies and innovations that are a direct result of what is learned in space exploration and from space research. Here are 41 years worth of "spinoffs."

    NASA Spinoff 2017

    I find there is a fairly significant number of people out there that have no clue about how important space exploration, space travel, and space industry is to the future of humanity. Their big argument is that money spent on space would be better spent on infrastructure and more everyday necessities. So here are a vast number of important innovations to showcase how everyone's lives are improved from just the "spinoffs" from the space program.

    Here is what is known about the various cores out there and their designation as of this date:

    1019 - Orbcomm 2 - on permanent display in Hawthorne

    1020 - (best guess) SES9 - destroyed on landing

    1021 - CRS8 and SES10 - to be retired and on display at the Cape

    1022 - JCSAT14 - sent to McGregor for multiple full duration test firings, to be retired as the "fleet leader"

    1023 - Thaicom 8, then converted to the first FH side core. Was just test fired in McGregor after a Hawthorne refurbishment. Still in McGregor

    1024 (best guess) - Eutelsat and ABS 2A - destroyed on landing

    1025 - (best guess) CRS 9 - exact location unknown at the Cape

    1026 - (best guess) - JCSAT16 - presumably stripped of good parts and in outside storage near SpaceX leased hangars away from the launch pads

    1027 - FH structural test article without engines. tested at McGregor. Location unknown but likely at McGregor.

    1028 (best guess) - AMOS6 - destroyed during static fire fueling

    1029 - Iridium NEXT 1 from Vandenberg. Best guess on the Cape after a west coast recovery and cross country truck ride

    1030 - Echostar 23 - expended after stage separation

    1031 - CRS10 - at the Cape somewhere after a good landing

    1032 - NROL-76 - at the Cape being processed to fly

    1033 - FH center core, now being tested in McGregor

    1034 - Inmarsat-5 - at the Cape being processed to fly

    1035 - CRS11 - just arrived at the Cape at the LC39-A HIF
