NASA operations engineer Daniel Velasquez, left, is reviewing the Mobile Vertipad Sensor Package system as part of the Air Mobility Pathways test project at NASA's Armstrong Flight Research Center in Edwards, California on October 17, 2023. The portable system allows Advanced Air Mobility researchers to test and evaluate several factors involved in monitoring takeoff and landing conditions at vertipad sites. "Vertipads" or "vertiports" will be where future air taxis will land and take off to transport passengers.
