Hello fellow Wikipedians,

I have just modified one external link on Free-return trajectory. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20160308063028/http://www.braeunig.us/apollo/free-return.htm to https://www.braeunig.us/apollo/free-return.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

I'd like to recommend adding a chapter for an Earth-Venus return trajectory. The reason I do this is because Venus is much easier to get to, as going inward and outward is easier than doing an outward-inward trajectory. I also propose this because Venus is shockingly more promising in interplanetary colinization than Mars, as the upper atmosphere (roughly around 50-55 kilometers above the surface) is actually the most earth like place in the solar system: the atmospheric pressure is similiar, the temperatures are manageable with climatizing technology, and humans would be shielded from solar radiation by the planet's thick ionosphere. What's more, tantalizing signs of life in the Venusian cloud decks have started appearing, and it just so hapoens to be at the height where proposals of extraterrestrial blimps to allow for astronauts to float above the venusian surface. All in all, an Earth-Venus return trajectory is worth discussing, and I highly recommend its own chapter in the article. GabMen20 (talk) 17:58, 4 December 2024 (UTC)[reply]
