NASA's lab in the sky

NASA's flying science lab cruises the skies over fracking fields and oil rigs to measure their impact on climate change. On this week's episode of TechKnow, Phil Torres goes airborne to learn more about a NASA program called SEAC4RS (Studies of Emissions and Atmospheric Composition, Clouds, and Climate Coupling by Regional Surveys) and a fleet of jets that are being utilized as flying laboratories to study pollution, climate change and the atmosphere.
