These colourful composite images of Mercury aren’t actually the result of NASA’s experiments with mind-altering substances: it’s what happens if you overlay spectral data about Mercury’s surface, collected with the Mercury Atmosphere and Surface Composition Spectrometer, with monochrome images captured by NASA’s MESSENGER spacecraft.
MESSENGER’s historic mission to Mercury is set to come to an end this month: after four years of orbit, it’s running out of fuel and can no longer combat the Sun’s push. This is a pretty good legacy to leave. [NASA]
