From Antarctica to Mars: Growing Food in Extreme Conditions

Even those of us with the greenest thumbs are baffled by the idea of growing food in Antarctica. From my tiny desk plant to my neighbor’s cabbage patch, plants generally have the same requirements: soil, sun and water. At the southern end of the planet, however, those are all scarce commodities. Nonetheless, on April 5, 2018, the team managing the EDEN-ISS greenhouse at Neumayer III announced that they had harvested 8 pounds of salad greens, 18 cucumbers and 70 radishes. This project has implications beyond just Antarctica, from moderate climates on Earth to future Mars missions. Continue reading

I’m not generally a space nut, but I do get a huge kick out of the work we’ve done to put rovers on Mars. I’ve felt pride and loneliness on behalf of the earlier rovers, Spirit and Opportunity, and cheered the unexpected longevity of their missions. They always felt so plucky and can-do; sort of a robotic extension of the American spirit on a daunting new frontier. Who’s a cute little robot pioneer doing incredibly valuable scientific exploration? You are! YOU ARE!

Earlier this month, hours after Mars Curiosity navigated it’s “seven minutes of terror” and successfully landed on the Red Planet, I laid in bed, having just soothed my daughter back to sleep. All that soothing had had the opposite effect on me: I was wide awake. I decided to try to wind myself back down by staring at the small illuminated screen on my phone and catching up on some tweets. What can I say? It makes me drowsy every…single…time…zzzzzzz. As I scrolled through my Twitter feed, I saw tweet after tweet from my friends and connections heralding the latest interplanetary achievement by NASA. Curiosity was on the ground! Successfully! They did it! The mood was nothing less than jubilant and awestruck, and I found myself getting completely sucked in. Yeah, this WAS super cool! I mean, we built a SKY CRANE? There was a guy with a MOHAWK? Whooo-hoo! USA! USA! USA! Continue reading
