🌱 🧬 Plant (genetic) engineering lags ~15 years behind other organisms... While the first genetic circuits were built in bacteria in the year 2000, and mammalian circuits followed a couple of years after, it was only until the late 2010s that similar genetic engineering efforts started in plants. However,...

Day 144, orbit 2233 — Many of you noticed the pink glow in the recent timelapses done in Columbus… That’s thanks to Veggie 🌱, the International Space Station’s vegetable production system — our little space garden! The Veggie chamber glows magenta-pink because it emits a light spectrum that’s perfect for plant growth! During Expedition 74, Veggie hosted the Veg-06 experiment, with two main goals: to study how alfalfa plants and beneficial bacteria work together in microgravity to capture nitrogen from the air and turn it into nutrients plants can use… and to look at how lignin – the material that helps plants stand upright on Earth – changes in space. The alfafa plants 🌿 were successfully grown – watered and nurtured by all of us – then harvested (aerial parts and roots) and stowed in a freezer. They were sent back to Earth for further analysis on board the CRS SpX‑34 cargo Dragon. For us, working on Veggie is a real taste of home – a reminder of what a garden looks and smells like. There’s something very special about watching the plants grow and caring for them day after day. I loved working on this experiment 💚 It is clear that being able to grow fresh food 🌶 in space will be crucial for long exploration missions, not just for nutrition, but for crew morale as well. A better understanding of nitrogen fixation is also key to improving soil quality on Earth, while studying lignin may benefit agriculture and forestry in the long run.
