Talk:Falcon X

Is Falcon X truly a "proposed spaceflight launch system"?

Based on a news source that has clarified SpaceX intentions, or rather, non-intentions, with the Falcon X today (10 Aug 2010), I believe we ought to initiate a discussion as to whether or not this topic is really sufficiently notable for a Wikipedia article as things currently stand. I'll say why in the next paragraph. But do note, I am not yet making a proposal for deletion, nor nominating the article for AfD, I just think all editors need to step back and consider whether the sources really support all the current assertions in the article and whether or not such assertions about the plans of SpaceX, if verified/verifiable, are notable at this point in time.

I do think the information published today (2010-08-10) at this news source, and the accompanying Spacevidcast video of a recent interview with Elon Musk, may offer a compelling reason for not (yet) having a SpaceX Falcon X article in Wikipedia. According to that source, "Elon emphasizes that the SpaceX heavy lift slides shown at the recent propulsion conference are just rough concepts and not part of any grand long term plan." IF that is true, appropriately verified to WP:V standards, etc., THEN I would think it calls into question the entire basis for this article, at least at this point in time. I am most interested in what others think on this matter. Cheers. N2e (talk) 22:05, 10 August 2010 (UTC)[reply]

Any opinions from the editors following this page? Otherwise I may propose the article for AfD to get input from the broader wiki-community. With the stories now published in major media (including Aviation Week) showing that Musk and SpaceX currently have no formal plans for either a Falcon X or Falcon XX, and that both rockets are mere concepts, I don't believe a consensus will be able to successfully argue that we need the two recently-created new Wikipedia articles on the (now) purely speculative future heavy-lift rockets.

I'm torn multiple ways on this. On one hand, the description of Falcon X and Falcon XX is entirely sourced off of one presentation which is more of a concept than any actual plan for vehicles. On the other hand, there is enough detail to create several paragraphs of description in the two articles. On the gripping hand, what information we have available on the Falcon X and XX concepts could be covered in a section of the parent SpaceX article, perhaps a "Future Concepts" section which could say where the X and XX came from and what the basic descriptions entail. I'd support taking this to AfD but my vote will be to merge some of the content into a section of the SpaceX article. --StuffOfInterest (talk) 01:32, 16 August 2010 (UTC)[reply]

Another alternative would be to merge the smaller XX article into this one, leaving the original as a redirect to it. -Arb. (talk) 22:20, 16 August 2010 (UTC)[reply]

According to http://images.spaceref.com/news/2010/SpaceX_Overview_TEM.pdf Falcon X is "all RP heavy lift", it's not an LH2 second stage. The XX given on page 13 has lower lift-off thrust but higher payload. This implies the second stage on the XX has a much higher ISP than the second stage on the X, and hence it would appear to be the candidate for LH2.

125,000 lb or 125,000 kg?

The article claims that Falcon X Heavy can put both 125,000 lb and 125,000 kg to LEO. Which one is correct? Remember that 125,000 lb = 56,700 kg = 56,7 metric tons. Urvabara (talk) 16:17, 22 August 2010 (UTC)[reply]
