The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets.Of course, launching a rocket powered by radioactive material has its own risks as well.

Explorers have always brought stowaways with them on board. Thanks to our travels around the world, hardy creatures like rats, goats, pigs and starlings and more have found their way to every corner of the globe. Not to mention our plants, microbes and viruses. Wherever we go, life goes with us, whether we want it to or not. And when we travel to other worlds, it looks like the most extreme life Earth has ever cooked up is ready and willing to make the journey with us. Now that the big flybys are over, it’s time to dig into the regolith, search for life in underground lakes and oceans, return samples back to Earth. We’re going to give life every opportunity to contaminate other worlds.What can we do to prevent it?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/newsletterSupport 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 - http://instagram.com/universetodayTeam: Fraser Cain - @fcain / frasercain@gmail.comKarla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comReferences:https://planetaryprotection.nasa.gov/overviewhttps://nodis3.gsfc.nasa.gov/OPD_docs/NID_8020_109A.pdfhttps://spacescience.arc.nasa.gov/wp-content/uploads/2018/11/ReviewAssessmentPlanetaryProtectionPolicyDevelopmentProcesses.pdfhttps://planetaryprotection.nasa.gov/about-categories/https://www.nasa.gov/feature/where-on-mars-might-humans-first-landhttps://www.youtube.com/watch?v=94bIW7e1Otghttps://arxiv.org/abs/1905.13681Support Universe Today Podcast
