The London Marathon was held earlier today, and among its runners? Astronaut Tim Peake, orbiting above the Earth on the International Space Station, and he set the world(?) record for running a marathon in space.
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.
