[edit] Neofuel
The Neofuel references ( 4 and 5 currently) need deleting or putting in some kind of perspective - its far from present technology levels - perhaps a 'futuristic proposals' section is needed? Comments? sbandrews (t) 18:37, 18 March 2007 (UTC)
- The Neofuel concept is lower technology level than any of the other technologies. Extracting water is called 'distillation' and putting water through a rocket is a 'hot water rocket', these are not high tech operations. This is not in any sense 'far from present technology levels'; this is so far inside that it is laughable. The article currently talks about glass fibre production on the moon. FFS glass fiber production on the earth requires an entire factory. In what sense is melting and distilling ice a far future proposal in comparison???? The only problem with the neofuel concept is simple, we don't know where the ice is. That is not a technology problem, that's an exploration issue.WolfKeeper (talk) 16:37, 29 November 2007 (UTC)
- Yes, I think this exemplifies how the article would benefit from having more structure. ISRU topics can be divided up a number of ways -- near-term vs. futuristic is an important one. Dividing by location (as the "examples" section has now) is also important, and the "Classificiation" section briefly outlines another way to think about it. But having discussion of a single topic spread out among the different ways its classified is just asking for duplication of text (at a minimum). Perhaps a section describing the different classification schemes could be followed by individual sub-topic sections that describe how that particular sub-topic would be classified?
- Specifically as regards neofuel, referencing some *other* source that describes the neofuel website author and his ideas would be the encyclopedic way to go. Sdsds 21:56, 18 March 2007 (UTC)
- Self published sources are permitted if the author has proven expertise on the subject he writes about. Are you challenging his credentials?WolfKeeper (talk) 16:40, 29 November 2007 (UTC)
- good, added a new section 'beyond current technology'.sbandrews (t) 22:14, 18 March 2007 (UTC)
- That classification is OR. On what are you basing it?WolfKeeper (talk) 16:37, 29 November 2007 (UTC)
- I'm going to try and reorganize the whole thing with Moon-Mars as two big sections, feel free to revert mercilessly :) sbandrews (t) 16:24, 23 March 2007 (UTC)
[edit] Mars
Is NASA even thinking about using ISRU for the return trip - we need to put their position here if they have one - kind of reminds me of the Moon landing debate about direct or moon orbit rendezvous :) sbandrews (t) 22:28, 18 March 2007 (UTC)
- The google search http://www.google.com/search?hl=en&q=%22mars+sample+return%22+isru+site%3Anasa.gov shows some interesting material. Sdsds 22:37, 18 March 2007 (UTC)
- nice - from there I found my way to here - which seems to me to indicate a direct approach - Exploration of Mars puts it delayed to 2016 or 2025 - at least that gives plenty of time to develop the technology :) sbandrews (t) 23:07, 18 March 2007 (UTC)
[edit] it is likely
The lead currently includes, "it is likely missions to planetary surfaces will also use solar power." I don't understand the tense used here. The Mars Exploration Rovers are already being very successful using solar power on a planetary surface! Sdsds 17:19, 23 March 2007 (UTC)
[edit] Title
The capitalization of the article title is questionable. I'm guessing the departure from the Wikipedia Manual of Style is based on the use of the phrase to derive the acronym, ISRU. I think this is insufficient reason, but maybe that's just me. I don't want to disturb other editors who may have different opinions so I won't "boldly" make the change, but I would appreciate some discussion, perhaps a poll? Paul D. Anderson 04:59, 13 May 2007 (UTC)
- I see the point. Are there many places in the referenced literature that use "In-situ resource utilization"? (Sdsds - Talk) 05:53, 13 May 2007 (UTC)
- support - I'd be happy with moving to "In-situ resource utilization" sbandrews (t) 07:24, 13 May 2007 (UTC)
[edit] Article structure by location or by resource
The article might be more compelling if, rather than structuring the sections by location, they were structured by resource. So for instance, "Water" is immediately understood by the reader as a resource which, if found in-situ, would be utilizable. So too "Oxygen". "Methane", "Carbon-dioxide", etc, would perhaps need more motivation. To my reading the article goes into some ideas (e.g. the manufacture of solar cells or glass in-situ) way too soon compared with the mining of basics like life-support and propulsion supplies. (Sdsds - Talk) 18:40, 13 May 2007 (UTC)
- I strongly concur Paul D. Anderson 20:31, 13 May 2007 (UTC)
[edit] Other locations
I noticed that someone added this section, with sources, and then another user deleted it, simply stating "no". No, what? What was wrong with the section? (I really hate it when people delete material without taking it to the talk page or at least giving more than "no" as to the reason for deletion — even if I agree with the deletion, which here I do not.) Ben Hocking (talk|contribs) 14:34, 22 August 2007 (UTC)
- I agree. It looked pretty good to me. I propose we reinstate it. At present the article only refers to Moon and Mars, but there are many other locations to consider. Especially for example the asteroids, both main belt and NEO, as well as Phobos and Deimos.Charles 20:26, 26 August 2007 (UTC)
[edit] Out of Date Reference
The link in reference 13 "NASA Capability Roadmaps Executive Summary. NASA." is out of date and please update. Andrew Swallow (talk) 08:19, 29 November 2007 (UTC)
[edit] Criticism section unreferenced
I removed this section from the main article until it can be supported with references:
- (Heading: "Criticism") While it is without doubt that ISRU will provide a spur to technological innovation that will one day prove useful, a question mark hangs over whether it is a cost effective technique for accelerating present exploration of space. One critique points out that the rather long lead in time proposed for lunar ISRU means that for the first decade of lunar base build up ISRU may actually hinder the program by taking up valuable cargo space for little return. However, lunar resources are only one of those available for use.
It appears to be original research (i.e., the personal opinion of the editor) rather than documentation of public criticisms.Sanddune777 (talk) 00:33, 6 February 2008 (UTC)
- the ref was this, taken out by a recent edit, probably as the link is/has been broken for a while,
