Discussion
The Mars at sunset might also be reference to "alpenglow." A simple Google of "alpenglow" should suffice as explanation 172.68.54.126 (talk) (please sign your comments with ~~~~)
The explanation starts out saying that this list includes all the other planets in our system as well as a couple moons, however uranus and saturn are clearly left off the list. 108.162.238.37 15:16, 28 October 2016 (UTC)
- Retracted, I did not understand the hypen in the last line. 172.68.78.125 16:18, 28 October 2016 (UTC)
Actually, the upper atmosphere of Venus has Earthlike temperature and Earthlike pressure - it is, indeed, pretty much the only planetary location in the Solar System safer enough than deep space to be worth the gravity well (you need a balloon to keep you aloft, oxygenated air, and protection from the sulfuric acid, but Earth air is a lifting gas on Venus so the first two solve each other). So "do not go to Venus" and "nowhere is even close to survivable except Earth" aren't quite true. The surface of Venus is absurdly inhospitable even to machines, but one shouldn't write off the whole planet so quickly. Magic9mushroom (talk) 04:02, 29 October 2016 (UTC)
- I definitely think the part about Venus atmosphere is not only hot and dense, but also highly corrosive is worth mentioning. Sulfuric acid, phosphoric acid ... -- Hkmaly (talk) 17:53, 29 October 2016 (UTC)
This could also be a reference to the short movie Wanderers by Erik Wernquist and narrated by Carl Sagan. In the movie we can see imaginary scenes where humans are trekking the solar system for personal exploration. /LordSillion -

Someone who is good at this kind of things should also change the transcript to get rid of the table. --Lupo (talk) 12:16, 18 January 2019 (UTC)
