Testing in a vacuum
Wraparound image from inside ESTEC’s Large Space Simulator. A vacuum chamber big enough to accommodate an upended double-decker bus, the LSS subjects spacecraft to the temperature extremes of space while in total airlessness for several weeks at a time. A dozen or more giant xenon lamps reflected in a mirror array simulate unfiltered sunlight. In everyday life, these lamps are more typically used individually, to illuminate IMAX movie projectors.
