#ExplainTheSun  - The Largest Migration on The Planet

In The Martian, Matt Damon plays an astronaut stranded, Robinson Crusoe-style, on the surface of Mars. Left for dead by his NASA crewmates and with limited food and water, Mark Watney’s situation looks dire. To stand any chance of survival, this STEM-savvy astronaut knows he’ll have to “science the s*** out of this” (as he puts it in the film’s trailer.) On this edition of “Science Goes to the Movies,” Ira talks with NASA’s “Mohawk Man,” JPL engineer Bobak Ferdowsi, and astronaut Don Pettit about their take on this Hollywood thriller, where space geekery takes center screen.

Science Goes to the Movies: The Martian

Once, there was the ordinary incandescent light bulb. It shone brightly, but wasted much of the energy put into it as heat. Then came the compact fluorescent. And as costs have dropped, consumers have increasingly been switching to light-emitting diode (LED) technology for many lighting applications, in an ongoing search for a more efficient bulb. Now, in work published in the journal Nature Nanotechnology, researchers report that nanophotonic devices may be able to breathe new life into old incandescent technology. Marin Soljačić and Ognjen Ilic, two authors of the study, explain how they’ve been able to “recycle” some of the incandescent bulb’s wasted heat and re-emit it as visible light, boosting efficiency.
