• Fourier Spectrometer PFS
  The Planetary Fourier Spectrometer (PFS) orbiting Mars on ESA s Mars Express works by breaking down light into a spectrum of individual wavelengths, in the same way that a glass prism converts white sunlight into a rainbow of its component colours. Instead of the light we see, PFS is built to study a range of radiation from short wavelength infrared just beyond the threshold of the human eye up to longer infrared – which is the heat radiation we feel with the nerve endings in our skin. PFS covers the widest infrared range of any instrument ever to orbit Mars or the Earth.
