NASA's ER-2 aircraft is prepared for a check flight by Eric Hintsa, scientist of the Unmanned Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS) instrument, on May 13, 2022.

An ER‑2 aircraft based at NASA’s Armstrong Flight Research Center in Edwards, California, carries a pod full of instruments for the INjected Smoke and PYRocumulonimbus Experiment (INSPYRE) on Thursday, July 9, 2026. This Earth science campaign studies wildfire‑generated thunderstorms. Researchers are seeking to better understand how these storms form, how high the storms send smoke, where this smoke travels, and the effect after the smoke reaches upper layers of the atmosphere.
