@peterrhague A couple of semi-scholarly links: https://t.co/tWiCEiuZK1 https://t.co/L3YVmhZgiH ... If we're talking about sustaining 6 people in a little Mars can for a few months, maybe. But a real city-sized colony? I just can't see any of the mitigation
@FuSchmu @Stonekettle Ain’t nobody going to grow up ON Mars. Maybe UNDER the surface of Mars, because with no magnetosphere life ON Mars is bombarded with 15 to 50 times the ionizing radiation of Earth. That includes crops, which do not thrive. https://t.c
@electronluke @MikeBenchCapon The same paper points out: ‘biomass growth was significantly decreased by 32% for cress and 48% for rye during the first 4 weeks after germination.’ https://t.co/heGI83nkNr
