For the first astronauts to visit Mars, what to eat on their 3-year mission will be one of the most critical questions. It’s not just a matter of taste. According to one recent estimate, a crew of six would require an estimated 10,000 kilograms of food for the trip. [...]
Robert Jinkerson, a chemical engineer at the University of California (UC), Riverside, thinks the answer is for astronauts to grow their own on-board garden—in the dark, with plant growth fueled by artificial nutrients rather than sunlight. [...]
Jinkerson believes it can be done by reawakening metabolic pathways plants already possess—the same ones that power the germination of seeds buried in the ground and then shut off once a seedling’s leaves start to reach for the Sun. In his vision of the future, electricity from solar panels could transform water and carbon dioxide (CO2) exhaled by a spacecraft’s crew into simple, energy-rich hydrocarbons that genetically modified plants could use to grow—even in the darkness of space or the dim light on Mars, which receives less than half as much sunlight as Earth. [...]
“It could be implemented in places like the South Pole, in places where agriculture is not possible,” says Jinkerson, whose team has already won two rounds of a NASA competition. [...] “It allows us to reimagine what agriculture can be,”
Death Stranding. Bought it a while back, but wasn't in the mood for a more contemplative/atmospheric game then. Now seems to be a good time to appreciate running errands!
