Beyond Earth (start time 5:10) Many have dreamt of colonizing other planets. It’s been a staple of science fiction for decades. Most often, people imagine creating a colony of humans on Mars, where people would live on a cold, dry planet with a thin, unbreathable atmosphere. Mars, however, may not be the best destination for future human colonization. In fact, Titan, a moon of Saturn, may hold greater hope for extending humanity’s presence in the solar system. Either way, humans face tough but surmountable challenges as we move beyond Earth. As a planetary scientist, Dr. Amanda Hendrix is actively involved in the scientific research and future mission planning that will enable humans to settle on other planets. She’s the co-author, with Charles Wohlforth, of the new book Beyond Earth: Our Path to a New Home in the Planets. Listen to How On Earth’s Alejandro Soto’s interview with Amanda Hendrix, where they discuss the opportunities and challenges for human space exploration.

NASA Visit // IPCC Report

wg2coverEarth Day gives us plenty of reason to reflect on the state of the planet and the impact we humans have had on it. This week’s show featured Dr. Linda Mearns, a senior scientist at the National Center for Atmospheric Research in Boulder, who is among hundreds of scientists who produced the latest report on global climate change. She’s a lead author of a chapter on regional climate change in the Fifth Assessment Report (AR5) of the United Nation’s Intergovernmental Panel on Climate Change. She also co-authored previous IPCC assessments – in 1995, 2001, and 2007. Dr. Mearns talks with How On Earth host Susan Moran about the science and implications of the IPCC report, including what it means for Colorado and the broader U.S. West.

Unfortunately, due to a technical glitch at the station, the recording of that live interview was lost. But we still have audio from our second feature.

Charles Bolden, the top administrator at NASA, was here in Boulder last week, touring the classrooms and facilities that earn the University of Colorado more space agency dollars than any other public university in the nation. We’ll hear what he has to say about CU’s role in the space program — past, present and future.

We’ve also recreated the Earth Day tribute that opened the show. These days it’s more like Earth Week, and it’s not too late to catch some of the planet-happy celebrations going on in the Boulder area this weekend. Listen for details.

We Are the Martians

(Start time 5:15) “The Men of Earth came to Mars. They came because they were afraid or unafraid, because they were happy or unhappy, because they felt like Pilgrims or did not feel like Pilgrims. There was a reason for each man. They were leaving bad wives or bad towns; they were coming to find something or leave something or get something, to dig up something or bury something or leave something alone. They were coming with small dreams or large dreams or none at all…it was not unusual that the first men were few. The numbers grew steadily in proportion to the census of Earth Men already on Mars. There was comfort in numbers. But the first Lonely Ones had to stand by themselves…”

That’s from Ray Bradbury’s great 1950 collection of short stories, The Martian Chronicles. Today, there are plans being made to send people to Mars, a fraughtful trip of a hundred and a half million kilometers and more than a year, each way. To learn whether we will be the Martians, we chat with Brian Enke. Brian is a Senior Research Analyst at the Southwest Research Institute in Boulder, a member of The Mars Society, and the author of the 2005 science fiction novel about Mars, Shadows of Medusa.
