Q&A WITH A LUNAR HABITABILITY EXPERT

What is the LEAF experiment?

LEAF stands for Lunar Effects on Agricultural Flora and is essentially a plant growth chamber, similar to those in an indoor farm on Earth. LEAF provides the plants with everything that they need to survive – water, nutrients, light, a comfortable climate – but also protects them from the extreme environment in space. The instrument will observe plants as they grow,environment in photosynthesis. We'll also conduct investigations at a biomolecular level to look at how the plants change their behaviour to protect themselves in space environments.
