A planet is a planet is a planet. Unless it’s Pluto – then it’s a dwarf planet. But even then it’s a planet, according to experts. So what was behind the unpopular re-classification of Pluto by astronomers, and were they justified? As the New Horizons spacecraft closes in on this small body, one planetary scientist says that this dwarf planet could be more typical of planets than Mars, Mercury, and Saturn. And that our solar system has not 8 or even 9 planets, but 900. Also, meet a type of planet that’s surprisingly commonplace, although we don’t have one in our solar system: super Earths. Could they harbor life? And the DAWN mission continues its visit to the two most massive residents of the asteroid belt: Vesta and Ceres. Discover what these proto-planets may reveal to us about the early solar system. Guests: Alan Stern – Planetary scientist, Southwest Research Institute, Principal Investigator of the New Horizons mission Marc Rayman – DAWN Mission chief engineer and mission director David Stevenson

Hi ho, hi ho … it’s out with work we go! As you relax this holiday weekend, step into our labor-atory and imagine a world with no work allowed. Soft robots help us with tasks at home and at the office, while driverless cars allow us to catch ZZZZs in the front seat. Plus, the Internet of Everything interconnects all your devices, from your toaster to your roaster to … you. So there’s no need to ever get off the couch. But is a machine-ruled world a true utopia?

Who’s watching you? Could be anyone, really. Social media sites, webcams, CCTV cameras and smartphones have made keeping tabs on you as easy as tapping “refresh” on a tablet. And who knows what your cell phone records are telling the NSA? Surveillance technology has privacy on the run, as we navigate between big data benefits and Big Brother intrusion. Find out why wearing Google Glass could make everything you see the property of its creator, and which Orwellian technologies are with us today. But just how worried should we be? A cyber security expert weighs in. Also, the benefits of an eye in the sky. A startup company claims that their suite of microsatellites will help protect Earth’s fragile environment. And Gary catches a cat burglar! Guests: Robert Gehl – Professor in the Department of Communication, University of Utah. His article, “A Mind Meld with the Surveillance State” appeared in an online issue of The Week. Hal Rappaport – Technology consultant for businesses, author of the paranormal thrill

Face it – humans are pattern-seeking animals. We identify eyes, nose and mouth where there are none. Martian rock takes on a visage and the silhouette of Elvis appears in our burrito. Discover the roots of our face-tracking tendency – pareidolia – and why it sometimes leads us astray.

You are surrounded by products. Most of them, factory-made. Yet there was a time when building things by hand was commonplace, and if something stopped working, well, you jumped into the garage and fixed it, rather than tossing it into the circular file. Participants at the Maker Faire are bringing back the age of tinkering, one soldering iron and circuit board at a time. Meet the 12-year old who built a robot to solve his Rubik’s Cube, and learn how to print shoes at home. Yes, “print.” Plus, the woman who started Science Hack Day … the creation of a beard-slash-cosmic-ray detector … the history of the transistor … and new materials that come with nervous systems: get ready for self-healing concrete. (Photo is a model of the first transistor built in 1947 at the Bell Telephone Labs in New Jersey that led to a Nobel Prize. Today’s computers contain many million transistors … but they’re a lot smaller than this one, which is about the size of a quarter. Credit: Seth Shostak.) Guests: Lucy Beard – Founder of

Alien life. A flurry of recent discoveries has shifted the odds of finding it. Scientists use the Kepler telescope to spot a planet the same size and temperature as Earth … and announce that there could be tens of billions of similar worlds, just in our galaxy! Plus, new gravity data suggests a mammoth reservoir of water beneath the icy skin of Saturn’s moon Enceladus … and engineers are already in a race to design drills that can access the subsurface ocean of another moon, Jupiter’s Europa. Meanwhile, Congress holds hearings to assess the value of looking for life in space. Seth Shostak goes to Washington to testify. Hear what he said and whether the exciting discoveries in astrobiology have stimulated equal enthusiasm among those who hold the purse strings.

What goes up must come down. But it’s human nature to want to put things back together again. It can even be a matter of survival in the wake of some natural or manmade disasters. First, a portrait of disaster: the eruption of Tambora in 1815 is the biggest volcanic explosion in 5,000 years. It changed the course of history, although few people have heard of it. Then, stories of reconstruction: assembling, disassembling, moving and reassembling one of the nation’s largest T. Rex skeletons, and what we learn about dinos in the process. Also, the reanimation of Gorongosa National Park in Africa, after years of civil war destroyed nearly all the wildlife. And a handbook for rebuilding civilization itself from scratch.
