Specifically, that we could live on Mars.<\/p>\n Biologist Kelly Weinersmith and cartoonist Zach Weinersmith have spent the last four years researching what it would look like if we did this anytime soon. In their book A City On Mars, they get into all sorts of questions: How would we have babies in space? How would we have enough food? <\/p>\n They join host Regina Barber and explain why it might be best to stay on Earth. <\/p>\n![\"\"\/](\"https:\/\/media.npr.org\/assets\/img\/2025\/04\/18\/04.21.25-ep-96f156c6702c5058307c5ed2c5de1d243c166563.jpg?s=2600&c=100&f=jpeg\")
