## Caption

Time for your glow up 🌟

Pictured here, NASAAmes teams use unsteady pressure sensitive paint (uPSP) to show how air pressure acts on different parts of the Space Launch System rocket.

During ascent through the atmosphere, a launch vehicle and its payload experience strong aerodynamic loads that are difficult to measure. During the design process, these loads must be estimated accurately, and wind tunnel buffet testing is still the best option.

The uPSP measurements are made by illuminating the painted model in the wind tunnel with blue light. The uPSP fluoresces red, and the brightness of the fluorescence is proportional to the pressure acting on the paint. Pressure fluctuations at up to 5,000 Hz can be resolved and measured.
