Since the FAI uses the term Karman line wouldn't it make sense to create a page to that effect and to redirect one of these to the other?

Ooops, I see that's been done already. JimD 21:24, 2004 Jun 21 (UTC)

[edit] The U.S. definition

Most of the following is copied from Reubenbarton's and my discussion pages:

Reubenbarton, I'm just writing to tell you that I feel it was extremely rude of you to add this change to the Boundary to space article. What I'm fired up about is not as much that I feel that this info doesn't belong there, but the fact that you submitted this as a "minor" change (which it clearly wasn't).

Regarding the Gagarin/FAI statement itself: I don't know whether it's true or not, and frankly, I cannot be <behind>ed to check (any resonable person would consider Gagarin's flight a spaceflight). In any case, this info just doesn't belong in that article. I understand how the preceding paragraph might have prompted you to add it, but it still doesn't belong in that article. Besides, nobody in their right mind would take the reported cynic's claims seriously anyway and the info on it is more of an attempt to refute it than anything else.

And yes, I know I shouldn't get protective of articles I started because I don't own them after submitting, but there you go.

The sources for the Gagarin statement are:
 The Encyclopedia Astronautica - Vostok 1:
 http://www.astronautix.com/flights/vostok1.htm

"...Gagarin ejected after reentry and descended under his own parachute, as was planned. However for many years the Soviet Union denied this, because the flight would not have been recognized for various FAI world records unless the pilot had accompanied his craft to a landing."

and the FAI Sporting rules on Astronautics: http://www.fai.org/sporting_code/sc08.pdf

"2.12.4 The pilot and crew of an aerospacecraft shall remain inside the vehicle during descent and landing. For spacecraft any method of descent and landing is acceptable provided the method is described in detail in the pre-flight plan."

What is the reference for this statement?

"Some cynics argue that the U.S. definition exists solely for historical reasons, because after the Yuri Gagarin PR disaster the U.S. needed an astronaut, and fast, so they might have decided to lower the bar a bit." Rusty 22:54, 25 Jul 2004 (UTC)

Hm. I noticed that the above FAI pdf is dated 25 April/1 August 2003, so this particular document isn't proof that the Soviets "cheated against FAI rules" (because it doesn't say what the rules were in 1961.) But anyway. Maybe they did, maybe they didn't. This particular issue/clause certainly wouldn't make me consider Gagarin's flight less of a spaceflight. If you've got clear proof then maybe this could... oops, ok, I see you have added this info to the Vostok 1 article. So then I think it can't hurt to back up this change/charge with some bulletproof evidence.
Talking of bulletproof evidence, I don't have such for the paragraph reporting the cynic's view on the U.S. definition. It's just something I heard people say, like, repeatedly over here in Germany. I could of course start looking for proof on the web now, but I cannot be bothered. Again, I didn't mean to have a go at the U.S. To fully quote the related sentences:
Some cynics argue that the U.S. definition exists solely for historical reasons, because after the Yuri Gagarin PR disaster the U.S. needed an astronaut, and fast, so they might have decided to lower the bar a bit. If that were true however, it would have been an unnecessary step: Alan Shepard, the first U.S. astronaut, travelled 185 km (115 miles) up.
Again, my intention was not to slander the US, but to put the cynic's claims into perspective: Alan Shepard travelled 185 km up, which kinda tells something about the aforesaid cynic's interpretation.
All that said, I wouldn't scream murder if the above sentences got removed. It's only vaguely related trivia anyway and doesn't offer hard and fast evidence on how the U.S. definition was arrived at. To play it fair, you could e.g. call a vote (to potentially facilitate which I copied this stuff to/wrote my response (here) at Talk:Boundary to space.)

No I wouldn't think of changing the statement. You insist on including it and your admission that you can't be bothered looking up facts and to placing POV unsubstantiated statements in the article should stand on their own. These kinds of facts should help readers to decide on the value of the article.Rusty 03:07, 27 Jul 2004 (UTC)
Oh come on! Do you absolutely, positively WANT to believe that I'm "teh enemeh"? Are you so keen on believing that my intention was sinister and not to inform of alternative and/or non-US point of views? Is it so hurtful to you to even learn of the existance of such views? Do you have to shoot at the messenger because you think the messenger agrees with the message? Despite me making it very clear that if anything, the opposite is the case? Listen: I've removed the said sentences. If people want to put them back in, fine, but I'm not going to touch them anymore. I cannot help but feel sorry: It must be really frightening to live with a frame of mind where the world appears to be out to get you. Ropers 18:53, 27 Jul 2004 (UTC)
Just remember, it is not I who have removed a single word from the article. It is you that chose to practice censorship and I didn't make a move to reverse it. I just expressed my views in the discussion page after being attacked and called "rude" for just doing what Wiki is about. You mentioned Gagarin in the edge of space article and so did I. I backed my statement with sources (here are additional sources: Encyclopedia Astronautica, BBC Science page, WWW.Worldspaceflight.com, WWW.Space.com) and you did not. I ask for a source and get a aspersions and false pity heaped on me. That must mean you don't have a source. I invite you to read the latest version of the Vostok 1 article. I believe it has a neutral POV. It states the facts of the flight. I have also built a timeline of the flight from various internet sources. Have a nice day. Rusty 21:36, 27 Jul 2004 (UTC)
Right. So marking a real change as a minor edit is "doing what Wiki is about"? Are you at all familiar with this Wikipedia policy? And since when does removing off-topic info from a specific article equal censorship? I felt your initial action was rude against the backdrop of accepted Wikipedia policy. You accuse me of practicing censorship based on what? Show me I've behaved badly and I'll apologize. Ropers 13:46, 28 Jul 2004 (UTC)

[edit] Boundary of Space

Wouldn't Boundary of Space make a much better title? I have never heard anyone say "boundary to ________", only "boundary of __________". Besides, it is the boundary of space. Or perhaps if you'd rather the "Boundary of Earth's Atmosphere"? Well, I will let you decide, and perhaps if no one replies I will move it. Moogle 05:41, 30 Sep 2004 (UTC)

[edit] Space does not equal orbit

There has been a tendency to document so-called "common misunderstandings" in these space and orbit related pages on Wikipedia. For every fact, it seems to me, there are a hundred possible misunderstandings. We are having enough difficulty documenting the facts, nevermind supposedly "common" misunderstandings. This is not supposed to be an encyclopedia of common misunderstandings.

But even if it were, the "common misunderstanding" documented in this article, that "space does not equal orbit" is not "common" in my experience. I have never, ever heard or read that reaching space was misunderstood as reaching orbit. I think possibly what is happening is that an editor (or editors, but I think there is only one) is documenting his own misunderstanding or the misunderstandings of a colleague or family member.

It also seems to me that a "common misunderstanding" which can be resolved by simply referring to a dictionary should rarely, if ever, be documented here for the well established reason thet Wikipedia is not a dictionary: We do not provide dictionary definitions. Nobody who is prepared to refer to a dictionary could confuse entering space with performing an orbit.

We must provide encyclopaedic articles on both Earth orbit and this subject, the boundary to space. That some may confuse the two is no more likely than many other confusions. If there are 1000 distinct, unrelated facts then 1,000,000 false connections between them could possibly be arrived at by the ignorant. We can document the 1000 facts not the 1,000,000 false connections: We cannot hope to double guess the wilfully ignorant by deciding which of the 1,000,000 possible misconceptions we must debunk.

Were I to trawl through Wikipedia recording all of my previous misconceptions I would create a lot of useless noise and annoyance, even if I just did the ones I felt were common. F'rinstance: I once thought, a long time ago, that Spain was the capital of France. Once of my other childish misunderstandings but apparently one which is fairly common was that you see in a radar-like fashion by emiting a beam from one's eyes. In a similar theme I also was convinced, as are many, that electricity travelled outbound along the red wire and the black wire until it met at the lightbulb where the collision caused the light. And a more serious misunderstanding, commonly held, was that wood came from stuff sucked up from the ground whereas mostly the mass of wood comes from the air. But these misunderstandings, and many others like them, I am not going to document in the articles here at Wikipedia unless someone starts an article of common and comical misuderstandings

For these reasons I intend to replace the section with a simple reference such as See also: orbit. But I also intend to remove it because it is plainly off topic. Comment invited.

[edit] Uses of External links

Also see the article on the Kármán line under External links below, which has an excellent explanation on how this boundary was determined.

The explanation should be incorporated into the article, not mentioned in passing. --[[User:Eequor|η♀υωρ]] 01:48, 5 Oct 2004 (UTC)

[edit] Boundary to space / Karman line as title

(William M. Connolley 17:38, 28 Nov 2004 (UTC)) It seems very odd to me to use Karman line as the "main" title for this page rather than the far-more-obvious boudary to/of space.

Boundary to space is certianly more clear and specific, but is there such a thing? Duk 18:29, 28 Nov 2004 (UTC)
(William M. Connolley 19:44, 28 Nov 2004 (UTC)) If there isn't such a thing, then the article is in need of revision: The boundary to space or edge of space, according to definitions by the Fédération Aéronautique Internationale (FAI), lies at a height of 100 km (about 62 miles) above Earth's surface (ie. in technical terms 100 km above mean sea level).
Yes, good point. Further down in the article there is a note;FAI apparently doesn't itself use the precise words "boundary to space" or "edge of space". Duk 19:58, 28 Nov 2004 (UTC)
Some of the sections should be moved to outer space.

[edit] image

it would be neat if the image were broken up and displayed on each of the pages for spheres, and each section of the image were clickable and went to the article on that sphere. but still looked the same as it is. probably possible with a table. like an "atmosphere taxobox". - Omegatron 01:08, Jan 8, 2005 (UTC)

It would also be better if the image showed the Karman line. User:Zntrip00:44, 15 August 2005 (UTC)

yeah, I agree. am I allowed to edit the image to include the karman line? (not sure about copyright issues) --75.108.173.67 10:34, 17 October 2006 (UTC)

[edit] Karman line equivalents

Has anyone ever calculated the equivalent of the Karman line for other planets, such as Mars, for example.

[edit] AP magnetic index

Hi. The article uses the term "AP magnetic index", which is mysterious to this casual reader, and which Wikipedia doesn't have an entry for. Reading this page I'm thinking a better substitute is "fluctuations in the Earth's magnetic field". Does that seem right? William Pietri 06:21, 20 September 2006 (UTC)
