Humans to Mars. That’s the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. It’s a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least.But there are two places humans can go which are a stepping stone between Earth and Mars. Base camps that would let us gather our resources in relative safety before dropping down into that gravity well.I’m talking about the moons of Mars: Phobos and Deimos.Our Book is out!https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport 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/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comReferences:https://www.youtube.com/watch?v=MZD5nnScDkshttps://solarsystem.nasa.gov/moons/mars-moons/phobos/in-depth/https://solarsystem.nasa.gov/moons/mars-moons/deimos/in-depth/https://pdfs.semanticscholar.org/85b0/1edc59d0667525bb546281b3a12997f32204.pdf?_ga=2.250002438.1632319045.1568499640-640080446.1568499640https://space.nss.org/media/2003-Space-Colonization-Using-Space-Elevators-From-Phobos.pdfhttp://www.csc.caltech.edu/talks/hopkins.pdfhttps://www.geekwire.com/2019/safest-bet-space-settlers-believe-inside-mars-moon-deimos/Support Universe Today Podcast

We’re learning more and more about extrasolar planets, and for the first time, astronomers have discovered water vapor in the atmosphere of a planet orbiting another star. The planet is located in the habitable zone of its star, so this might even be rain.Of course, it’s not all good news, it’s much more massive than Earth, with higher gravity, and is probably bathed in radiation from its red dwarf star. But, it’s a good start in the search for habitable places in the Universe, places where there might be life.Our Book is out!https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport 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/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comReferences:https://www.spacetelescope.org/news/heic1916/https://www.theguardian.com/science/2019/sep/11/rocky-super-earth-k2-18b-named-most-habitable-known-world-beyond-solar-systemhttps://arxiv.org/abs/1707.04292http://exoplanet.eu/catalog/k2-18_b/https://www.wolframalpha.com/input/?i=surface+gravity+calculator&assumption=%7B%22F%22%2C+%22GravitationalAcceleration%22%2C+%22r%22%7D+-%3E%226371.000+*+2.2+km%22&assumption=%7B%22FS%22%7D+-%3E+%7B%7B%22GravitationalAcceleration%22%2C+%22g%22%7D%7D&assumption=%7B%22F%22%2C+%22GravitationalAcceleration%22%2C+%22M%22%7D+-%3E%225.972%C3%9710%5E24+kg+*+8%22&assumption=%22FSelect%22+-%3E+%7B%7B%22GravitationalAcceleration%22%7D%7Dhttps://sci.esa.int/web/cosmic-vision/-/59796-esa-s-next-science-mission-to-focus-on-nature-of-exoplanetshttps://www.youtube.com/watch?v=XR_uEh0qhk4https://www.youtube.com/watch?v=8PstUvHlKEghttps://www.youtube.com/watch?v=uCTGIxmM-e4Support Universe Today Podcast

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-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport 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/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comReferences:https://www.youtube.com/watch?v=0WN7lS9bpB4https://map.gsfc.nasa.gov/mission/observatory_l2.htmlhttps://hal.archives-ouvertes.fr/hal-00568378/documenthttps://www.nasa.gov/mission_pages/stereo/main/index.htmlhttps://www.nasa.gov/mission_pages/stereo/news/entire-sun.htmlhttps://www.youtube.com/watch?v=598UtgxFd1Ehttps://map.gsfc.nasa.gov/https://wind.nasa.gov/http://sci.esa.int/herschel/https://www.esa.int/Our_Activities/Space_Science/Herschel/The_largest_infrared_space_telescopehttps://www.esa.int/Our_Activities/Space_Science/Planckhttp://sci.esa.int/gaia/https://www.youtube.com/watch?v=lxgdcG_NQyAhttp://www.russianspaceweb.com/spektr_rg.htmlhttps://www.bbc.com/news/science-environment-49504866https://www.theatlantic.com/science/archive/2018/07/nasa-james-webb-space-telescope-northrop-grumman-cost/566186/https://www.jwst.nasa.gov/http://sci.esa.int/euclid/https://www.nasa.gov/content/goddard/wfirst-wide-field-infrared-survey-telescopehttp://sci.esa.int/plato/https://www.youtube.com/watch?v=uCTGIxmM-e4https://www.youtube.com/watch?v=p0SMNucXwgohttp://sci.esa.int/athena/https://arxiv.org/ftp/arxiv/papers/1211/1211.3462.pdfhttps://www.universetoday.com/142896/the-lunar-gateway-will-be-in-a-near-rectilinear-halo-orbit/https://www.youtube.com/watch?v=q2c7nZB-040Support Universe Today Podcast

Thanks to gravity, there are places across the Solar System which are nicely balanced. They’re called Lagrange Points and they give us the perfect vantage points for a range of spacecraft missions, from observing the Sun to studying asteroids, and more.Various spacecraft have already visited Lagrange Points, used them for some or all of their missions, and there are fascinating plans in the works that could put new missions and even space colonies into these balanced places in the Solar System.Let’s explore the Lagrange Points.Our Book is out!https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport 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/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comReferences:https://solarsystem.nasa.gov/resources/754/what-is-a-lagrange-point/http://www.planetary.org/blogs/emily-lakdawalla/2014/02070836-isee-3.htmlhttp://sci.esa.int/lisa-pathfinder/47363-fact-sheet/https://neocam.ipac.caltech.edu/page/Orbithttps://www.pnas.org/content/103/46/17184.full#sec-7https://phys.org/news/2017-03-nasa-magnetic-shield-mars-atmosphere.htmlhttps://www.researchgate.net/publication/268569275_Terraforming_Venus_A_Challenging_Project_for_Future_Colonizationhttps://www.nasa.gov/pdf/604657main_4-%20GER%20Stakeholders%20Workshop%20Earth-Moon%20L1_L2%20Bobskill.pdfhttp://www.niac.usra.edu/files/library/meetings/fellows/mar05/1032Pearson.pdfSupport Universe Today Podcast
