Rachel Jacoby Zoldan is a beauty, health and lifestyle writer based in New York City. Her work has also appeared Refinery29, Men's Journal, Redbook, SELF, InStyle, HGTV Magazine and the Huffington Post. When she's not writing or editing, she's probably running, taking a yoga class or on a Spin bike somewhere. Thinking about really great leggings. (Also, maybe, the couch, too.)
The camera in your phone, the insulation in your walls, and that oh-so-comfortable mattress you sink into nightly: You can thank NASA for these—and more.
