FLEX takes on mutants

25.08.2016 by Kaido Reivelt

Because a plant isn’t green doesn’t mean it can’t photosynthesise as well as its more usual counterpart, but when measured by satellites, these non-green varieties skew results on plant health. FLEX is different. Experiments using ‘mutants’ show that colour won’t be an obstacle in this new mission’s task of mapping plant health from space.
