Growing organs in microgravity was the experiment that hooked me. Apparently, they’re experimenting on the space station with 3D printers that grow human organs, like hearts, in zero gravity. The difficulty with growing organs on earth is that soft tissue (“biomaterial”) tends to collapse while it’s being printed, unable to hold a shape and turning to mush before it’s completed. In space, the replicated tissue can hold its shape long enough for cells to growth more tightly together in a culture, eventually becoming strong enough to return to earth’s gravity. That’s the theory, anyway.
I learned about this while digging further into the amazing experiments performed by Astronaut Christina Koch, who just completed a record 328 days in space. As the NY Times reported today, she came home safely after a near-year on the international space station. She also completed three all-female spacewalks.
However, it’s the number and breadth of experiments she conducted that may make the most difference to future generations of spacefarers. After all, if we’re going to check out the interstellar neighborhood, we’re going to need to know how to eat real food, practice medicine, and put out fires. You know, domestic affairs. Who better to do all that than Christina Koch, given the old saying that a woman’s place is in the home.
Do You Think that Spacesuit Makes You Look Fat?
The faces of the early space pioneers were all male, of course, selected from the military, which excluded the likes of notable female pilots Amelia Earhart and Harriet Quimby from its ranks. Actually, to be fair, this bias was in the American space program, since Valentina Tereshkova of the USSR was the first woman in space way back in 1963, only two years after the first American man had gone up.Continue reading “A Woman’s Place Is…In Space”
