What colour is an asteroid? The latest instrument being prepared for ESA’s Hera mission for planetary defence will observe its target Dimorphos asteroid in a range of colours far beyond the limits of the human eye. In the process Hera’s HyperScout H hyperspectral imager will help prospect the asteroid’s mineral makeup – in the process helping to deduce how best to deflect future asteroids which might one day endanger Earth.
