Earth in Human Hands – Shaping our Planet’s Future

Sometimes when we are having personal or health problems, it helps to get an outside perspective: talk to other friends who have experienced similar problems and how they dealt with them, and other friends about how they avoided those problems.  Talk to experts.  Then using all that input, we try to make the best choice to solve the problems and to live a long and happy life.  This is perhaps the situation we find ourselves in now with the health of our environment and the long-term viability of the human race.  So where to we look for that “outside perspective” and expert help?  The answer may be: look to other planets and talk to those who study them.  This is the approach astrobiologist Dr. David Grinspoon takes in his new book: “Earth in Human Hands: Shaping Our Planet’s Future”. Dr. Grinspoon is a senior scientist at the Planetary Science Institute, an adjunct professor at the University of Colorado, and in 2013 he was appointed the inaugural Chair of Astrobiology at the Library of Congress.  We had a chance to talk with Dr. Grinspoon about how he compares Earth’s story to those of other planets, and how our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective.

The podcast of the show is below, and you also can hear the extended interview here.

2016 Retrospective

2016-resetFor this end-of-the-year How on Earth show, we look back to 2016 with clips from some of our features from the past year: selections from the Our Microbes, Ourselves series, research about Zika, gravitational waves, and carbon farming.  Those are just a few of the topics we covered in 2016, which also included: electric cars, electric airplanes, renewable energy, climate change, using the microbiome as indicator of length of time after death, star gazing, pesticides, life on other planets, planets around other stars, stars in other galaxies, eggs, plant diversity, marine animal sex, wildfires, recent science graduates describing their thesis work, PTSD, light pollution, pollinators, lead in water supplies, Alzheimer’s research, the Rosetta mission, the New Horizons mission, missions to Mars – past, present, and future, sleep, cell phones, and more!

The Rosetta Mission

rosetta_descent_smallRosetta [feature starts at 5:27]
The Rosetta Space Mission has been in flight for ever 12 years and will be ending with a dramatic crash this Friday morning around 10:40 UT (4:40 am Mountain time) – it’s an event that will be watched and talked about by people around the world.

Rosetta is run by the European Space Agency, with contributions from NASA. The mission’s goals have been to study a comet to learn not only about how comets work, but what comets can tell us about the origins of the solar system, and perhaps connections to water and life. Rosetta was the first spacecraft to orbit and escort a comet as the comet approached and flew past the Sun, and Rosetta also carried a smaller spacecraft, named Philae, that performed the first landing on a comet.

The Rosetta mission has a very strong Colorado connection, since one of the instruments – an ultraviolet spectrograph called “Alice” – was operated from the offices of Southwest Research Institute right here in Boulder.We have three members of the Rosetta team here in the studio to talk about Rosetta, comets, and the rather exciting ending planned for the spacecraft in just a few days. Our guests are Andrew Steffl from Southwest Research Institute, John Pineau from Stellar Solutions, and John Noonan who is a recent astronomy graduate from the University of Colorado and is working at Southwest Research Institute.

There’s more information on the Rosetta Blog about how to follow the final events of the Rosetta mission.

Gregory Benford – Science Fiction/Fact and Starshot

What are the qualities that make a good scientist?
What are the qualities that make a good science fiction writer?
515tlGA1GTL._UX250_Those skills do not necessarily overlap, but when they do, they not only can produce wonderful works of speculative fiction based on hard science, but they also can generate exciting new ideas for science research.

Our guest on today’s show inhabits both worlds; he is a professional scientist and a well-known science fiction writer. Dr. Gregory Benford is a professor of physics at the University of California, Irvin, where he has been a faculty member since 1971. Benford conducts research in plasma turbulence theory and experiment, and in astrophysics. He has published papers in fields of physics including condensed matter, particle physics, plasmas, mathematical physics, and even in biological conservation and geoengineering.

image3Dr. Benford also is a Nebula Award winning author of over twenty novels, including “Timescape”, “Jupiter Project”, “Artifact”, and “Against Infinity”, and the 6-book “Galactic Center Saga” series.  He also is an advisor on the Breakthrough Starshot project that has the goal to fly a spaceship to the nearest star.

In Colorado, a boom in methane development over the past few years has raised questions about whether the environmental impacts are outpacing scientists’ ability to measure them. Shelley Schlender and Daniel Glick discuss the current state of the science looking into fracking’s impacts.  Here is a compendium of scientific, medical, and media findings demonstrating risks and harms of fracking.

Across the Universe – You Can’t Get There From Here

grinspoon-perkowitz-galaxy
This special edition of How on Earth is produced in conjunction with the Conference on World Affairs.  Our guests are two of the participants of the Conference: astrobiologist Dr. David Grinspoon and physicist Dr. Sidney Perkowitz.  In keeping with the traditional format of the conference panels, our guests will start by talking about their interpretation of the topic “Across the Universe – You Can’t Get There From Here”, and we’ll go from there and see where in the universe we end up.

Pollinators and Insecticides (starts at 10:06).  Although they may be hidden in the chill of winter, crickets, bees and thousands of other insects play a critical role year-round in how we grow the food we eat. Dr. Jonathan Lundgren, a South Dakota-based entomologist, talks with host Susan Moran about how predator insects serve as biological pest controls. Dr. Lundgren’s research on adverse effects of a controversial class of insecticides, called neonicotinoids, on pollinators such as honeybees and monarch butterflies,  has made him the target of political pressure from his employer, the U.S. Department of Agriculture. A watchdog group has filed a whistleblower complaint on Lundgren’s behalf against the USDA. Dr. Lundgren recently started a research and education farm, called Blue Dasher Farm, which promotes regenerative agriculture.
