Short summary
During the double Lunar-Earth Gravitational Assist with the ESA/JUICE (Jupiter Icy Moons Explorer) spacecraft in August 2024, we acquired hyperspectral data cubes of both the Moon and Earth with the MAJIS (Moons And Jupiter Imaging Spectrometer) imaging spectrometer under challenging, real in-flight conditions. This allowed to characterize surface materials and thermophysical properties on the Moon, identify various cloud phases and gases in Earth's atmosphere, and thoroughly validate the performance of the instrument.
