message: I don't know that much about space, but don't the light and dark side of the earth represent night and day in the course of 24 hours, instead of being similar to lunar phases? Could anybody who knows verify this?  —Preceding unsigned comment added by 145.18.242.174 (talk) 15:44, 4 March 2008 (UTC)
replies: text: The light and dark side of the earth represent an earth day as the earth rotates about itself relative to the sun. A lunar phase is exactly same as as the moon rotates about itself (and orbits the earth) relative to the sun. So while the moon always has one face to the earth, it still has night and day relative to the sun. njaard (talk) 00:34, 25 August 2008 (UTC)

message: Hi all. I would love to see the "Geometry of Earthrise" rewritten in a way to make it more accessible to the greater audience. Most of the terms there left me stymied. Cheers. Shiningheart (talk) 06:07, 24 December 2009 (UTC)
thread_title: Laymen's Terms

message: I agree it is confusing, to me.  No matter the orientation of the camera, I would call a line perpendicular to the horizon and thru Earth, as "UP".  From the surface of the moon, that should be 'obvious' to everyone.  And because I presume the spacecraft orbits (and landings) are fairly equatorial (they don't have to be), the Earth equator should also be aligned with 'up'. (but some of the composite pics (accidentally?) show Earth's equator as almost horizontal!  This should only occur if the photo is taken from near a lunar pole!
BTW: Because the moon wobbles a bit, Earth, wherever it can be seen from the moon's surface, wobbles around by about 1/4deg (called nutation), which would only be noticeable from the small areas on the moon, where Earth is close to the horizon (also describable as near the 'edge' of the moon as seen from Earth).  173.66.81.65 (talk) 01:52, 24 December 2023 (UTC)
replies: text: Yes, I've always been unclear on the meaning of "original orientation" in this context. Is it relative to the label on the camera? Relative to the astronaut's head? Which astronaut? Spiel496 (talk) 16:36, 7 May 2024 (UTC)

replies: text: I was going to post the exact same comment, but since you already did I'll just say that I agree. If the article were about the general concept of the Earth rising over the Moon's horizon, it would be relevant. But this article, at least according to the note at the top, is supposed to be about a specific photograph that was taken from orbit. Still, the information is interesting and perhaps could be framed more explicitly as a digression. --Itub (talk) 17:13, 3 September 2010 (UTC)
thread_title: Add to biblography

message: It's notable that the image is almost always shown rotated 90 degrees compared to how Anders framed and took it. As far as he was concerned, the spacecraft was orbiting around the "waist" of the Moon, and "up" and "down" were aligned with the Moon's axis.
Borman, however, framed his shots as though they were flying over the Moon's surface as in an aircraft. See http://www.abc.net.au/science/moon/earthrise.htm

replies: text: You are confusing "up" with north, a common misconception.  In freefall, "up" is somewhat arbitrary, but should be defined as normal to the surface of the object being orbited, or opposite to the local gravitational vector. --96.236.44.24 (talk) 15:54, 24 December 2013 (UTC)
thread_title:  Which Way is Up? 

message: The idea for such a photograph seems to have came to one from a psychedelic state. I have read it in a quite-recent book about psychedelics, the title of which I cannot remember right now. If anyone gets more information about this, feel free to post more. Twipley (talk) 22:11, 7 January 2013 (UTC)

replies: text: The user is directly referring to the overview effect and indirectly to the original book upon which it is based, namely, The Overview Effect: Space Exploration and Human Evolution (1987).  When the overview effect is discussed, the Earthrise photograph is often used as an example.  According to the literature on this subject, when astronauts look back upon Earth from space (or in this case, from the Moon), they experience what has been described as an epiphany and a feeling of unity.  This experience is often described as a cognitive shift in awareness, and people who take psychedelic drugs (or entheogens) report similar experiences, except their physical bodies are on Earth not in space.  Stranger still, much of the drug literature describes the sensation of flying through space, flying through what can only now be described as "wormholes", seeing the Earth from above like a flying bird, and viewing the planet from space.  Anecdotally (and stranger even still), certain specific drugs may even produce visions of space travel, with users coming away from the experience with an imperative to begin planning the trip!  This was exactly what happened to Timothy Leary and others when they started promoting their beliefs in SMI2LE (space migration, intelligence increase and life extension).  Four decades later, this is all mainstream now, with companies like Google funding Google X and Calico.  For more information, see psychonautics. Viriditas (talk) 11:10, 25 December 2013 (UTC)

thread_title:  Earthset page? or make a more generic title 

message: The description of a simulation video (section 2013 simulation video), purporting to show what the mission crew saw as they came around the moon, is wrong. The orientation of the view seen by the astronauts was 90° to the left of the usual, misleading orientation of the published Earthrise picture. The actual view seen, and the original image photographed, shows the earth to the left of the moon, not above it. When NASA released the image to the public, they rotated the image 90° to the right to make it resemble a familiar terrestrial photograph. Therefore, contrary to the claim in the article, the simulation video does not in fact show the view as the astronauts witnessed it. — O'Dea (talk) 08:21, 26 December 2018 (UTC)
thread_title:  Simulation error 

message: I've never understood why the apparent size of the Earth from near the Moon, and showing the Moon's horizon for context in the famous Earthrise photo, appears to be no larger – or perhaps even slightly smaller – than the Moon appears to be in the sky from the surface of the Earth. One would naively think the Earth should appear much larger in the Moon's sky. Does anyone have an explanation for this illusion? Milkunderwood (talk) 08:31, 16 August 2019 (UTC)
replies: text: From this true-size comparison it seems to be accurate. But the same question from the opposite perspective: I've wondered why, compared to Earthrise, the Earth looks so large in this image. Randy Kryn (talk) 12:07, 16 August 2019 (UTC)

message: The boundary between day and night on our planet appears quite abruptly in this picture. It must be less than half an hour from totally day to darkest night.

message: People seeing this photo may try to identify the part of the earth not hidden beneath the clouds. I had hoped to find that info on this Wikipedia page, but eventually found the answer on Google Earth. It's the coast of Western Sahara and Mauritania: https://earth.google.com/web/@4.31023303,-12.11909962,-3708.76404606a,14619651.75135612d,35y,-137.1775918h,1.69205241t,-0r/data=OgMKATA.
