For the August 20 How On Earth show we offer two features:
Kepler Spacecraft’s Uncertain Future: (start time 5:48) Are we alone in the cosmos? Are there other planets out there, and could some of them support life? Or, is Earth somehow unique in its ability to support life? The Kepler mission was designed to start addressing that question by searching for planets around other stars. Since its launch in March 2009, the Kepler spacecraft has discovered many diverse candidate planets around other stars, but recently the spacecraft has run into some technical problems. Dr. Steve Howell from NASA’s Ames Research Center talks with co-host Joel Parker about Kepler’s past, present and future.
Cancer’s Impact on Fertility: (start time 14:52) It’s tough enough to receive a cancer diagnosis. For many patients, an added insult is that chemotherapy treatments can render them infertile. However, there are many options for cancer patients who want to have children, or more children – both men and women. A key problem has been that many of them aren’t educated by oncologists about their fertility options and they jump right into drug treatments. Dr. Laxmi Kondapalli, an assistant professor of reproductive endocrinology and infertility at the University of Colorado Denver and head of the CU Cancer Center’s Oncofertility Program, talks with co-host Susan Moran about the medical science of take cancer therapies and the latest in fertility-preservation options.

Today we’re joined by Dr. William Alley and Rosemarie Alley to learn about the nuclear waste crisis in the United States. Bill Alley, a distinguished hydrologist, was in charge of the USGS’s water studies at 
Buzz Aldrin’s Vision for Space Exploration (starts at 6:14) Dr. Buzz Aldrin advocates that the United States should not enter a space-race to the moon against the Chinese, or a race to Mars against the Russians, but rather show leadership by cooperating with the major space-faring nations to systematically step across the great void to the Red Planet. This is his personal Unified Space Vision. He is also working toward an independent council, a United Strategic Space Enterprise, that would advise American citizens about the nation’s space policy. USSE experts would draw on a deep knowledge of America’s previous successes and failures to present a unified plan of exploration, science, development, commerce, and security within a national foreign policy context. Buzz shared these visions with How On Earth’s Jim Pullen. Here’s an excerpt from his hour-long discussion with Jim. Stay tuned for the rest of his discussion, in which he shares little-known insights into why Apollo 11, not Apollo 12, was first to land humans on the moon, and never-before-shared honors for Neil Armstrong and Pete Conrad.
Good & Bad Calories (starts at 4:50) Ever since the 1970s, the rise of obesity in the United States has an epidemic. Researchers around the world are trying desperately to figure out why so many of us get fat, and what we can do to change that. A large amount of funding, and support from public health policy, goes toward the hypothesis that we get fat because we eat too many calories and do not exercise enough; when someone eats more calories than they need, the instructions go, they should exercise. That’s “Calories in, Calories Out.” But recently, an expert with a different point of view spoke to a packed audience of doctors, staff and medical students at the University of Colorado Medical Center. The expert is 
Feature #1 – China’s Environmental Impact (start time 4:46): China’s meteoric economic rise is causing harmful side effects, ranging from choking air pollution domestically to threatened forests, wildlife and air quality around the globe. Of course China’s per capita greenhouse gas emissions still pale in comparison to those in the United States, and roughly one-third of China’s CO2 emissions are generated to manufacture goods that are exported to the U.S. and other nations. Craig Simons, a former journalist and author of a recently published book, 
Feature #2 – 100 Year Starship (start time 15:35): Science and exploration tend to be long-term commitments. That’s well-known by fans of the “Hitchhiker’s Guide to The Galaxy” series, where the computer Deep Thought did calculations for 7.5 million years to find the answer to The Ultimate Question of Life, the Universe, and everything. However, projects on our world tend to be limited by shorter-term political and funding cycles. So it is hard enough to consider projects that require thinking a decade into the future, beyond many political lifetimes. What about projects that require thinking a century or more into the future, many generations from now? Well, that is exactly what one group of space exploration advocates is working toward. The project is called the
