Talk:Mesosphere

message: I noticed that the "coldest temperature" is listed as 200 K, but in fact the temperature in the summer mesopause gets much colder, down to about 100 K.  The temperature at the summer mesopause is thought to be a sensitive indicator of global change, and greater thermal energy in the lower atmosphere.

replies: text: 50 miles = 80.467 kilometers. (1 mile = 1.609344 kilometers) Therefore, 80 kilometers better represents 50 miles. DAK4Blizzard (talk) 02:19, 4 June 2009 (UTC)

thread_title: Particles in Mesosphere

message: Does anyone know at what altitude the sky turns from blue to black? Then again, the altitude probably varies with latitude (because the altitude of the layers of the atmosphere vary with latitude), so perhaps a better question is in what layer of the atmosphere does the sky turn from blue to black?

replies: text: In 2004, a pilot set an altitude record for a private spaceship. He reached a maximum altitude of 212,000 feet (64.62 km), which is in the mesosphere. The sky turned from blue to black for him somewhere during his flight (the article fails to specify where). He took off from the Mojave Desert, so he was presumably in a mid-latitude area of the atmosphere. From experience of flying up to 40,000 feet in mid-latitudes, I know the sky is obviously still blue in the lower part of the stratosphere. Therefore, it seems that the sky turns from blue to black somewhere between the lower stratosphere (40,000 feet) and middle mesosphere (212,000 feet). So now the question is, where in that range does the sky turn from blue to black? DAK4Blizzard (talk) 00:10, 24 May 2009 (UTC)
replies: text: I'll answer my own question from a year ago. The sky turns black at around 60,000 feet (~11.5 miles or ~18.5 km) altitude, which is in the lower to middle stratosphere. This makes sense, because there really isn't much air (which causes the sky to appear blue) above where commercial planes fly at ~35,000 feet. (See the video, Ride on a U2 spy plane and this website.) DAK4Blizzard (talk) 22:32, 20 May 2010 (UTC)
replies: text: Confirmed. It's about 60k feet. I searched all over the net for an answer to this question and was faced with a lot of unhelpful know-it-alls who failed to answer the question. At 60,000 feet 99% of the atmosphere is below you...and the sky is black.  — Preceding unsigned comment added by 209.193.21.1 (talk) 05:31, 8 July 2012 (UTC)

message: It's the second time I restore the sequence:
: [ mesosphere ] [typically refers ] to the range of altitudes below which commercial airliners fly but above which satellites orbit the Earth.
It's the second time someone flipped the "below" and "above", leading to airliners flying above mezosphere and satellites orbiting below. Sharpfang (talk) 15:11, 15 November 2021 (UTC)
replies: text: It's poorly worded, sounding confusing. The edit warriors probably weren't ill-intended. A better expression would be "refers to the space between the altitude commercial airliners fly at and the lowest altitude satellites (are able to) orbit at". 2001:4BC9:A43:39DB:FC2A:92F5:D58E:B48E (talk) 11:58, 29 August 2022 (UTC)
