====Initial review punch list====
*Intro seems a bit verbose. Perhaps another picture of the Grasshopper - to illustrate the concept of a rocket landing - would help?
**Re: Grasshopper photo:  I very much agree.  Have been endeavoring to find a Wiki-licensable photo of Grasshopper flying for 18 months now.  See extensive discussion on Talk page.  [[User:Huntster]], who is both very wiki-photo knowledgeable and an Admin on the English Wikipedia tells us that there simply are not any wiki-allowable images that anyone has yet found of Grasshopper in flight.  (although there are lots of good Youtube videos released by the company).  I've wondered whether perhaps a fair use criteria might work, but editors strong in wiki-photo fu have told me no dice.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 01:25, 28 February 2014 (UTC)
***{{Yellow tick}}—Hey [[User:Jamesx12345|James]].  See what I said before (above) about the challenges of obtaining a WP-license-able photo, and let me know if you are okay with this for a GA review.  The editor who provided me the rather strict interpretation of ''fair use'' and the WP license practices did allow that some other editors might not take as hard a line on it as he does.  However, I've not gone and tried to pursue a consensus from a larger group on this.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 20:50, 12 March 2014 (UTC)
****I'm afraid I don't know much about image licensing. It doesn't actually need any images at all for the purpose of a GAR, but they do make it easier to understand. Ideally, somebody would pay for me to attend a launch and I'd take a few snaps :-) [[User:Jamesx12345|James]]<sup>x</sup>[[User talk:Jamesx12345|12345]] 21:34, 12 March 2014 (UTC)
*****{{question}}—Oh, that might work.  We have a LOT of photos of the <u>launches</u>.  Anytime a rocket launches from a US government leased facility (such as the pads that SpaceX leases from the US Air Force), the USG takes lots of photos, and they are released under quite acceptable licenses.  So we could definitely get more of those; there is one in the article already.  
:::::The problem is our EXTREMELY limited photoset from anything at all related to the <u>reusable technology</u> (e.g., Grasshopper v1.0 flying, or of the landing-over-water tests).  These are private, SpaceX takes lots of photos; releases a very few to the press, but none with Creative Commons-acceptable licenses.
:::::So do you think we should just insert another photo of the rocket launching?  (beyond the one we have in the article now?)  None of that is reusable tech tests etc.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:19, 12 March 2014 (UTC)


**Re: tightening up the prose:  The article just went through a [[WP:GOCE]].  But one idea I had is that we could delete the following sentence from the second paragraph, as it is only summarizing details presented in the article:  "Eight low-altitude flight tests were made in 2012 and 2013. The first booster return controlled-descent test from high-altitude was made in September 2013, and a second test is planned for March 2014.[2][3]"  Would you think that would help? [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 03:27, 28 February 2014 (UTC)
***I think so. Schedules seem like the kind of info best kept for the main body of the article.
****{{done}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 21:54, 28 February 2014 (UTC)

*"occur at a velocity of approximately" - km/s would be adequate here, I think.
**I would tend to agree, but what is there is a result of somewhat involved Talk page consensus; moreover, the original source only gives the velocities in Mach numbers, which are approximate, and so we felt we ought to leave those Mach nos. in the encyclopedia prose.  And generally, in spaceflight related articles, we give velocities in both SI units and in English measurment units for a global audience.  Do you think the GA criteria would trump the Talk page consensus?  I would be happy to revisit the topic with the previous discussants.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 01:25, 28 February 2014 (UTC)
***If there is a local consensus to have it one way, I see no problem with that. [[User:Jamesx12345|James]]<sup>x</sup>[[User talk:Jamesx12345|12345]] 21:42, 28 February 2014 (UTC)
****Cool, then that's {{Approved}} by you.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 20:50, 12 March 2014 (UTC)

*"It said this was an approximation." - this single sentence looks a bit odd. It also makes the use of refs 6 and 7 a bit unclear.
**{{Fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:08, 28 February 2014 (UTC)
*I've tagged 4 dead links using Checklinks. There's also a {{cn}} needing fixed, but that might be covered by ref 46.
**{{in process}}
***The WPO article is based on this video by AP [https://www.youtube.com/watch?v=RkvLQdzZRFo] - I think that might be a better ref. [[Template:Cite AV media]] could be used for this purpose. [[User:Jamesx12345|James]]<sup>x</sup>[[User talk:Jamesx12345|12345]] 17:27, 11 March 2014 (UTC)
****Thanks.  Unfortunately that link at the AP only has a couple minutes of the news conference on it.  But I was able to locate another link, on the National Press Club archive.  I've added that video link (as you suggested) to the NPC line to supplement the (very good, but now dead) WaPo article.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 18:47, 11 March 2014 (UTC)
*****I've just removed the link altogether. I think it's probably less confusing that way, and just as good as an unlinked ref to a paper source. [[User:Jamesx12345|James]]<sup>x</sup>[[User talk:Jamesx12345|12345]] 20:38, 11 March 2014 (UTC)
******That's a good solution.  I wasn't sure what the standard is for that sort of thing (leave the link?  take it out?  what sort of note to leave? etc.)  I'm very glad that you, as an experienced GA reviewer, knew what to do with that. 
::::::In the meantime, I think I still have a couple more of the deadlinks to crawl through, and a few more "in process" items to work.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 21:36, 11 March 2014 (UTC)
::::::*{{Yellow tick}}—[[User:Jamesx12345|James]], I've looked and believe there are no more dead links.  But I don't know how to use ''checklinks'', so if you would please take a look at this and then let us know if you are good to go.

*"first stage is now being flight tested" - very liable to dating. Given that you and some other editors have focused on this article for a fair length of time, it should be OK, but an {{tl|As of}} or {{tl|Update after}} could be used.
**{{Fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:26, 28 February 2014 (UTC)
*"News of the new test rocket" - "News of the test rocket"
**{{Fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:40, 28 February 2014 (UTC)
*"re-entry database" - not sure what this is. From the context, it seems to be data that will allow a computer to work out where it will land, but I could be quite far off the mark.
**{{Fixed}}  It is really just a bunch of wind tunnel test data that shows how a very large rocket body (about 3.3 metres in diameter and over 50 metres long behaves at a bunch of different velocities and altitudes in the atmosphere, with the rocket body moving through the atmosphere in various orientations.  It's all quite essential for coding up the control algorithms to tell the engines and thrusters what to do based on where the returning rocket finds itself.  But I can really see how that esoteric info was quite unclear with the term "re-entry database".  Good catch! — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:40, 28 February 2014 (UTC)
*[[NASA]] can be linked in the first instance.

*"reusable rocket system that will be powered by LOX/methane, "an evolution of SpaceX's Falcon 9 booster", and reiterated SpaceX's commitment to develop a vertical landing breakthrough technology." - "reusable rocket system to be powered by LOX/methane, "an evolution of SpaceX's Falcon 9 booster", and reiterated SpaceX's commitment to develop a vertical landing technology." - update tense, rm "breakthrough" - don't think it's needed.
**This one is a bit more complex; principally because it is not a second LOX/methane technology; it is a second ''reusable rocket system'', and this one will be ''both'' much larger, and also will be powered by a different fuel (LOX/methane rather than LOX/RP-1 as in the Falcon 9 and Falcon Heavy).  At any rate, I've made a stab at making it more clear.  See what you think.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 22:54, 28 February 2014 (UTC)
***{{Yellow tick}}—[[User:Jamesx12345|James]]—Please me us what you think here.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 20:50, 12 March 2014 (UTC)

*"24-story" - this needs a source, preferably for the height in metres. In terms of buildings, the spelling should be storey.
**{{fixed}}.  Added a source, and eliminated the "24-story" reference completely.  BTW, in American English, the height of buildings is spelled "story", whereas it is "storey" in British and Canadian English.  There is one other reference to "12-story" in the article (about an earlier Grasshopper test flight).  Let me know if you think it might be better to eliminate that arcane sort of linear measurement as well now that I took out the "24-story" term. [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 00:15, 1 March 2014 (UTC) 
***I stand corrected. 
*"SpaceX made history in September 2013 when it relit" - "In September 2013, SpaceX successfully for the first time relit" - seems a bit promotional. My wording isn't great, it's just the "made history" that doesn't feel quite right.
**{{fixed}} — I've copyedited this, and eliminated the "made history."  Yes, sounds a bit promotional in that form.  It was an historic event, and something that had not been successfully accomplished with a booster rocket strictly under rocket-control (no aeronautical flight surfaces like wings or a lifting body, etc.) previously.  See what you think.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 23:51, 28 February 2014 (UTC)
*"for March 2014 at the earliest." - another ref needed. I'll stop referring to refs by number since they might change unpredictably as you add or move them.
**{{Fixed}} — and good idea on referring to them by some other means.  I'll just search for your textual clues.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 23:51, 28 February 2014 (UTC)
*[[Transonic]] can be linked.
**{{Fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 19:06, 1 March 2014 (UTC)
*There is inconsistent use of full stops in '''Technology.''' I think it's just 3 that are needed.
**{{Fixed}}, but recommend you take a look to see if the three remaining are the three you were thinking of. — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 19:06, 1 March 2014 (UTC)
*"and upon introducing space launch customers to the idea of putting a payload in space with a used stage" - quite colloquial "and upon space launch customers being willing to put a payload in space with a used stage" is a bit clearer, maybe.
**{{in process}}—not quite sure how to reword this...  The idea in the source is that this is ''very'' new thinking to the sorts of large customers who might buy launch services, and that customers may very well not warm to the idea of utilizing a "used" booster to carry their precious cargo to orbit ('they've never done it that way before' ... it has never been an option since government-designed space programs, in all nation-states that have gotten to space, have only built expendable systems, and even with that, they can only get a very small percentage of the liftoff weight (something like 3%) to orbit.  This really is a huge paradigm shift for the industry, '''if''' SpaceX are even successful in getting this expensive project to work at all.  At any rate, that is the idea behind "introducing space launch customers to the idea of putting a payload in space with a used stage" -- but I'm thinking on some ways to rephrase that.
***{{Yellow tick}}—[[User:Jamesx12345|James]]—please note my comment above and see what you think now. [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 20:50, 12 March 2014 (UTC)
****It looks OK now on second reading. If anything, I think more could be made of concerns about reliability (have any agencies said anything for example? I don't think the JWST would go up on a used booster, for example.)
*****Cool, one more down.  {{Approved}} by you.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 16:48, 13 March 2014 (UTC)

*"If all aspects of the test program go very well, and if a customer is interested, SpaceX said in September 2013 that the first reflight of a Falcon 9 booster stage could be done in late 2014." - "in September 2013, SpaceX said that if all aspects of the test program are successful and a customer is interested, the first reflight of a Falcon 9 booster stage could be done in late 2014."
**{{Fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 19:18, 1 March 2014 (UTC)
*"have a major impact on the cost of access to space" - not sure about the use of the quote here. I think there is probably some scope for expansion with regard to what it would mean for putting things in orbit.
**{{fixed}} — I have removed the direct quotation and rewritten the prose.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:03, 11 March 2014 (UTC)
*The '''Technical Feasibility''' section is a bit odd. I think it would be better if it were integrated into '''Technologies''', with the problems and solutions in one place.
**{{in process}} Two comments for now:  1) I believe the difficulty of this undertaking is of such a magnitude, and so many have thought quite impossible, that it probably does warrant a section on ''Technical feasibility'' to address this.  Moreover, while this sort of return/landing and reuse have been hypothesized for decades in Science Fiction and a few academic papers, none of the current space programs have even attempted full and rapid reuse.  2) Having said that, I do not believe the prose that was in the section adequately covered the problem nor the topic.  I have made several edits to broaden the explication of the problem, and how SpaceX has (to date) only a theoretical understanding that it can be done, and may be economic to do so.  I will look to make a few more changes here in the coming days.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:03, 11 March 2014 (UTC)
***{{Yellow tick}}—[[User:Jamesx12345|James]]—Okay, I've made a few more changes.  See what you think.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 21:28, 12 March 2014 (UTC)   
****{{question}}  I think maybe you didn't see this one yesterday.  [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 16:48, 13 March 2014 (UTC)


*The bullet points in '''Test program''' are also inconsistent re. full stops.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:42, 11 March 2014 (UTC)
*"tests of post-mission (spent) Falcon 9 booster stages" - that link is a bit confusing. I think that whole bullet could be made somewhat clearer, perhaps by starting with "September 2013..."
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:42, 11 March 2014 (UTC)
*"Grasshopper is a set of experimental technology-demonstrator..." - the two refs in that paragraph not at the end of the sentences - currently 33 and 34 - could be moved to the end.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:52, 11 March 2014 (UTC)
*"...flight tests of the vehicle are to occur in Texas." - ref needed.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 17:52, 11 March 2014 (UTC)
*"...and did so." - this is quite abrupt, and also needs a ref. I can't help but feel that there is a nicer way to say it.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 18:03, 11 March 2014 (UTC)
*"Four additional test flights were made in August 2013." - another ref, or instance of ref.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 18:03, 11 March 2014 (UTC)
*"Grasshopper version 1.0... and is 106 feet (32 m) tall." - is quite clumsy. Perhaps "Grasshopper version 1.0, the company's first test vehicle, consisted of a Falcon 9 [v1.0] first stage tank and pressuriser with a single Merlin-1D engine. It had four steel landing legs and a support structure, and stood 106 feet (32 m) tall." or something like that.
**{{fixed}} — [[User:N2e|N2e]] ([[User talk:N2e|talk]]) 18:36, 11 March 2014 (UTC)
*"In an arrangement unusual for launch vehicles,[18] some first stages of the SpaceX Falcon 9 v1.1 versions of the rocket are testing propulsive-return, over-water aspects of the reusable rocket technology." - this is quite confusing, and it is unclear what the ref supports - I would move it to the end of the sentence.

:::I did some further copyediting on this.
