A group of students and NASA Armstrong scientists are developing a small inexpensive glider that could help deliver more accurate weather forecasts. The device is called Weather Hazard Alert and Awareness Technology Radiation Radiosonde (WHAATRR) Glider, and it's based on NASA's Mars-bound, boomerang-shaped Prandtl-m drone. According to the agency, it could save the National Weather Service up to $15 million a year compared to its current methods. WHAATRR can also deliver more reliable data a lot faster. The National Oceanic and Atmospheric Administration (NOAA) could use WHAATRR as an airborne platform for its experiments, as well.
