Astronauts at the International Space Station have to work out every day to keep themselves healthy. This means they exercise two hours per day on three different machines—a bike, a treadmill, and the so-called Advanced Restive Exercise Device, ARED—to prevent loss of bone density and muscle mass. On the ISS there is enough space for these machines, but what about the less roomy deep-space vehicles like the Orion Spacecraft, on which NASA wants to send astronauts on long journeys to the moon and Mars?
Preparing a Thanksgiving feast in space is a lot easier than here on Earth, but the end after dehydration, irradiation, and rehydration aren’t exactly the height of appetizing. Still, the environment more than makes up for it, and apparently the cornbread dressing is (relatively) fantastic.
Interesting to see what microgravity teaches us about agriculture!
Don’t know why they use the word “microgravity”? If it’s in orbit, the effects of gravity have to be zero by definition… Because there is no such thing as “zero gravity”! There’s gravity from the sun all the way out here, it’s really more like no relative acceleration. As in microgravity, you’re actually in perpetual free fall.
I swear this is not a Hitchhikers guide reference…
This is a real question. Whale oil is a wonderful industrial lubricant and remains liquid at extremely low temperatures. It was almost certainly used in some NASA technology over the decades. But how much whale oil have we sent out into the cosmos?
Myanmar’s Inle Lake is one of the largest lakes in the country, but in the last 20 years, satellite images have been revealing what looks like a smaller surface area. The lake, however, is still there — it’s just hidden beneath a sprawling, floating tomato farm.
Salman Rushdie talks about these in Kashmir in Haroun and the Sea of Stories. I had no idea they were still a major agricultural practice. I seem to remember something similar in Lake Titicaca in Bolivia as well – but again, not as a major commercial player.
I didn’t fall asleep – I was trying to suffocate a fly in my eye…
Not all naps are created equal. Some naps have been shown to rejuvenate where others boost creativity. What’s more, when you nap can be as important as how you nap. Here’s how to nap like a professional, nap-taking machine. Here’s how to nap like you MEAN IT.
Sleep has been something I’ve come to respect more now that I train/exercise more. I’d been testing my training plan in September, and by mid November/December I was noticing I was getting run down. I’d have energy for a physical workout, but at my desk at work? I was powering down around 10 AM, after having difficulty waking around 6:30. I’d been passing it off as having to do with the days getting shorter and less light.
Although astronaut cuisine has improved considerably over the decades, this year’s Thanksgiving menu aboard the International Space Station still consists mostly of freeze-dried and dehydrated dishes. But future missions will likely have access to one fresh vegetable: sweet potatoes.
According to exobiologists at NASA, these mysterious shrimp and its symbiotic bacterium may hold clues “about what life could be like on other planetary bodies.” It’s life that may be similar—at the basic level—to what could be lurking in the oceans of Europa, deep under the icy crust of the Jupiter moon.
