Electrical power lines pose a serious crash hazard to helicopters and other air-based vehicles, especially small aerial vehicles such as unmanned aircraft systems (UAS). This is because power lines are so widespread, hard to see, and strung at roughly the same height above the ground at...

The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to non-target gases. Infrared (IR) absorption spectroscopy gives highly specific...

Over the past 60 years, NASA scientists and engineers have developed many advanced technologies and processes. But NASA has also partnered with industry, using commercially available products to complete its missions. Here, some of those companies join NASA in celebrating these collaborative successes.
