Chasing smoke is a round-the-clock business. Wildfire smoke can travel long distances and over several days, so NASA Explorers with the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) mission took to the field to find where it goes. From a plane directly above the Shady Fire in the middle of the afternoon to a valley in the Sawtooth Mountains at 1 in the morning, explorers are gathering important data about how fire smoke affects communities near and far.
