[edit] Alterations of Feb 2007

Again, I have removed several of your changes, this time to Primary Life Support System. Firstly, according to the manual of style, prose is preferable to lists where possible. In addition, you removed important text and made the quality of the writing frankly poorer. I really recommend that you take some time to carefully look over the manual of style and its subpages, and read Wikipedia:Guide to writing better articles before arbitrarily changing articles around for the worse. Not only have I had to correct numerous innaccuracies, wording problems, and style deviations from you on several articles, but I have read several complaints about your editing style from other editors. If you want to contibute helpfully to the project, you should consider taking this as constructive criticism, read over the relevant policies, and try to edit more carefully and deliberatively in the future. — Swpb talk contribs 18:19, 4 February 2007 (UTC)

  • The big deletion that you complained about was not deliberate but an editing mishap. Sorry. Apart from that, I do not see that I have removed any information from Primary Life Support System.
I have read several complaints about your editing style from other editors.

Please, what complaints?

What need is there to keep this article as closely as possible to as it was apparently copied from http://www.snds.com/ssi/ssi/Applications/SpaceSuits/LSS.html ?

I put the list of parts into list format to make it clearer which parts the gas passed through.
Your revert took out two items of information that I inserted, that I found from http://www.hq.nasa.gov/alsj/plss100.jpg:-

The absorbent canister is surrounded by a circulating water jacket to remove the heat produced as the absorbent works.
The spacesuit has a plug-in point for an external oxygen feed to flush out atmospheric gases such as nitrogen after sealing the spacesuit before use.

That information was not cited. The source you're giving now refers to the Apollo PLSS, whereas this page primarily discusses the EMU PLSS. That information would belong in a section on the A7L PLSS. — Swpb talk contribs 22:24, 4 February 2007 (UTC)

[edit] How is the oxygen stored?

I can't tell from the cutaway if the O2 canisters are pressure vessels or cryogenic dewars. The article doesn't say, either. Did the LEM have cryogenic dewars, or also only pressure vessels? I presume the suit vessels could be re-charged from the LEM system for multiple moonwalks, as on Apollo 17. How did that work? SBHarris 18:34, 12 June 2007 (UTC)

[edit] SI Units Missing

Currently this article gives measurements only in imperial units. Someone needs to add equivalent measurements using SI units. R160K 19:57, 23 July 2007 (UTC)

I have now added °C alternative to °F temperature. It was 12.77777 recurring.

[edit] Related science and technology

Seems to me this could do with a lot more relating and linking to the science and similar technologies of life support systems generally. Rexparry sydney 05:02, 6 August 2007 (UTC)
