Lagrange Points. Stable spots in space that you just can't stop thinking about. What spacecraft work best in which places? What are some amazing ideas that could utilize these regions across the Solar System?In the last episode, I gave an overview of the Lagrange points, and then went into the details of spacecraft missions sent to L1, the perfect place to constantly observe the Sun, the Earth, or to block radiation coming from the Sun. The best place for a lunar elevator, or a spot to put a space station at the Moon.This week, we're going to talk about L2 and L3, the other meta-unstable spots that you can park a spacecraft at.Our Book is out!https://www.amazon.com/Universe-Today...Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/u...RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list...Weekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-K...Astronomy Cast:https://www.youtube.com/channel/UCUHI...Support us at: http://www.patreon.com/universetodayMore stories at: http://www.universetoday.com/Twitch: https://twitch.tv/fcainFollow us on Twitter: @universetodayLike us on Facebook: https://www.facebook.com/universetodayInstagram - https://instagram.com/universetodayTeam: Fraser Cain - @fcain / frasercain@gmail.comKarla Thompson - @karlaii / https://www.youtube.com/channel/UCEIt...Chad Weber - weber.chad@gmail.comReferences:https://www.youtube.com/watch?v=0WN7l...https://map.gsfc.nasa.gov/mission/obs...https://hal.archives-ouvertes.fr/hal-...https://www.nasa.gov/mission_pages/st...https://www.nasa.gov/mission_pages/st...https://www.youtube.com/watch?v=598Ut...https://map.gsfc.nasa.gov/https://wind.nasa.gov/http://sci.esa.int/herschel/https://www.esa.int/Our_Activities/Sp...https://www.esa.int/Our_Activities/Sp...http://sci.esa.int/gaia/https://www.youtube.com/watch?v=lxgdc...http://www.russianspaceweb.com/spektr...https://www.bbc.com/news/science-envi...https://www.theatlantic.com/science/a...https://www.jwst.nasa.gov/http://sci.esa.int/euclid/https://www.nasa.gov/content/goddard/...http://sci.esa.int/plato/https://www.youtube.com/watch?v=uCTGI...https://www.youtube.com/watch?v=p0SMN...http://sci.esa.int/athena/https://arxiv.org/ftp/arxiv/papers/12...https://www.universetoday.com/142896/...https://www.youtube.com/watch?v=q2c7n...
