NASA’s airborne Lunar Spectral Irradiance, or air-LUSI, flew aboard NASA’s ER-2 aircraft from March 12 to 16 to accurately measure the amount of light reflected off the Moon. Reflected moonlight is a steady source of light that researchers are taking advantage of to improve the accuracy and consistency of measurements among Earth-observing satellites.

A new instrument with its eye on the Moon is taking off aboard a high-altitude NASA plane to measure the Moon’s brightness and eventually help Earth observing sensors make more accurate measurements.
