The Alien Hunter & SETI

Today’s show offers the following feature:
Extraterrestrial intelligence? (start time: 6:30): It’s mid-summer, a time when many of us like to spend leisurely time outside at night, gazing at the stars and planets, and asking the big existential questions, such as, Are we alone? Is there intelligent life waaay out there? Our guest today, science writer Sarah Scoles, has pondered these questions for several years. She discusses with hosts Susan Moran and Joel Parker her just-published biography, Making Contact: Jill Tarter and the Search for Extraterrestrial Intelligence. Tarter, an astronomer, directed the Center for SETI (Search for Extraterrestrial Intelligence) Research. Carl Sagan’s 1985 novel Contact” illustrates Tarter’s astronomical work. In the 1997 movie Contact (stemming from Sagan’s novel) actor Jodi Foster played a character who was loosely based on Tarter.

The Rosetta Mission

Rosetta [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.

Quantum Biology: Life on The Edge // Science and Art with Monica Aiello

Quantum Biology: Life on the Edge

What do Enzymes and photosynthesis have in common? Both are biological process that happen to rely on quantum mechanisims. That’s right, particles tunnling through walls, shifting between particle and wave states: The weirdness of the quantum world isn’t as isolated as we once thought. This past summer Life on The Edge, a book about the frontiers of quantum biology was released to US audiences. How on Earth corespondent Kendra Krueger caught up with one of the authors Johnjoe Mcfadden to talk more about the book and the weird science of quantum biology.

Science and Art with Monica Aiello

Monica Aiello is a visual artist who has worked with numerous scientific agencies to re-incorporate art into science. She and her husband work closely with earth scientists and NASA mission scientists, including scientists involved in NASA’s Voyager, Galileo, Messenger and Magellan missions. Their collaboration with scientists doesn’t just inform their art work, but is also part of their community outreach programs. Monica and Tyler Aiello’s work is featured in an upcoming exhibition called “Confluence” at the Space Gallery in Denver. Their work focuses on the Colorado River and the surrounding plateau.

Alcohol and weight gain (starts at 3:34): Science journalist Jill Adams shares the latest science on the connection between alcohol and weight gain. The science is murky, as she states in her recent column in the Washington Post.

Climate Clues in Coral (starts at 9:02): Despite certain appearances and rumors to the contrary, global warming has not been on holiday for the past decade. But increases in temperature at the Earth’s surface have slowed down, prompting scientists to work hard to figure out why. It seems that a lot of heat that has been building up in our planet’s climate system due to greenhouse gas emissions has winded up deep in the Pacific Ocean. Why? Diane Thompson, a post-doctoral scientist at NCAR and lead author on a new study, discusses with HOE’s Tom Yulsman how a sample of coral from a remote atoll in the tropical Pacific revealed some important answers.

Tropic forests love CO2 (starts at 16:04) It’s been known for some time that tropical forests are not only rich in biodiversity, but they also absorb a lot of carbon dioxide that humans spew into the atmosphere. But just how much greenhouse gases—namely CO2–these forests take up, say, compared with temperate and boreal forests, has been eluding researchers. Britton Stephens, an atmospheric scientist at NCAR, discusses with HOE’s Susan Moran a new study he co-authored. It suggests that tropical forests may be absorbing far more CO2 than many scientists had previously thought.

NASA Visit // IPCC Report

Earth 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.

2014 Science Stories // Spacecraft Experiments

For our first show in 2014 we offer two feature interviews:
Feature #1: We continue our conversation from Dec. 31 with science writer and CU professor Tom Yulsman about what “hot” stories 2014 holds in store regarding earth and planetary science, especially climate and weather. Yulsman, who also writes a regular blog for Discover magazine, called Imageo, talks with co-host Susan Moran.

Feature #2: In expectation of the first official cargo flight of the Cygnus spacecraft to the International Space Station, co-host Joel Parker interviews researchers David Klaus and Stefanie Countryman about their respective experiments: a biomedical antibiotic experiment and an educational K-12 experiment involving ant behavior in microgravity. The Cygnus spacecraft is built by Orbital Sciences Corporation, and follows the earlier, successful launch of a Cygnus demo flight on October 22. The experiments are built by the BioServe Space Technologies Center within the Aerospace Engineering and Sciences Department at the University of Colorado, Boulder.

Wildfires & Water Reservoirs // Comet ISON

For the Sept. 3rd How On Earth show we offer two features:

Wildfires Threaten Water Supplies: (start time 5:45) The wildfire burning in and around Yosemite National Park is now the fourth-largest in California’s history. Covering nearly 350 square miles, the Rim Fire is threatening the Hetch Hetchy Reservoir, which supplies residents in the San Francisco Bay Area with most of their water and power. It’s a lot like the 2012 High Park Fire—which sent ash and debris into the water supply of Fort Collins. These fires offer lessons on the risks wildfires pose to reservoirs. Dr. Bruce McGurk, a former water manager for Hetch Hetchy and a water consultant, speaks with How On Earth contributor Brian Calvert about the risks and future prospects.

Comet ISON Cometh: (start time 12:50) Comets have fascinated humans for millenia. Aristotle argued comets were hot, dry exhalations gathered in the atmosphere and occasionally burst into flame. Some people thought that comets replenished Earth’s air. Still others believed they were a source of disease. Scientists today study comets because some are thought to be relatively pristine leftover debris from the formation of the solar system. And studying what comets are made of can provide us a glimpse back to the beginning of the solar system 4 billion years ago. Comet ISON, as scientists call it, is one that scientists predict will be relatively easy to view later this year. Dr. Carey Lisse, a senior research scientist at the Johns Hopkins Institute Applied Physics Laboratory in Maryland, speaks with co-host Joel Parker about comet ISON and its fascinating tails. For more information on ISON, go to NASA’s ISON toolkit, and this cool interactive model.

Planetary Sciences Budget // Curiosity’s RAD

Curiosity’s RAD (start time 7:14). To design a successful manned mission to Mars, we’ll have to know a lot about the radiation environment between the Earth and Mars and on the planet’s surface. The Radiation Assessment Detector (RAD) instrument on Curiosity is designed to make those measurements. We talk with Southwest Research Institute’s Dr. Donald Hassler, the RAD instrument Principle Investigator, about RAD’s purpose, how the instrument works, and the joys and scary moments that come with working on Mars.

Planetary science budget (start time: 15:49). Despite the successes of the Mars missions and voyages to our other planetary neighbors, the White House decided that NASA’s planetary science budget should be drawn down. The hit would be substantial, a twenty percent reduction from 2012. 300 million dollars would be removed from a baseline one and a half billion dollars. We ask Dr. Alan Stern, who has served as the chief of the Science Mission Directorate at NASA, about why the planetary science budget should be restored.

Pluto’s Moons // Wildlife Preservation

(credit: NASA, ESA, M. Showalter, Z. Levay)”]Feature #1:
Last month, astronomers working on the Hubble Space Telescope announced the discovery of another, fourth moon around Pluto; this moon is so small that it could fit easily inside Boulder County (a pretty tricky thing to find at a distance of three and a half billion miles). The researchers who found the new moon were making observations in support of NASA’s New Horizons spacecraft, which is en route to fly by and study Pluto in 2015, and continue onward to explore the mysterious region beyond Pluto’s orbit known as the Kuiper Belt. How On Earth’s Ted Burnham recently met with Alan Stern, principal investigator on New Horizons, to talk about what the discovery means for that mission. [An extended version of the interview also is available.]

Feature #2:
The significant loss of species on Earth is primarily due to human destruction of habitats, forests and other wild nature, to make room for new development and agriculture. Climate change is also accelerating the rate of species extinction. Among the efforts worldwide to protect wilderness and nature so wild animals can survive is a Boulder-based nonprofit called The WILD Foundation. Harvey Locke is the organization’s vice president for conservation strategy and he helped launch the Yellowstone to Yukon Conservation Initiative (Y2Y) several years ago and oversees a global campaign called Nature Needs Half. Y2Y’s goal is to create a continuous 2,000-mile corridor for wildlife from Yellowstone National Park in the U.S. to the Yukon in Northern Canada. Harvey joins us in the studio to talk about that campaign and the science behind wildlife preservation targets.
