Ariel Waldman, the author of What’s It Like in Space? Stories from Astronauts Who’ve Been There, is a member of NASA’s Innovative Advanced Concepts program, which nurtures radical, sci-fi-esque ideas to enhance and transform future space missions. She also contributed to a congressionally-requested National Academy of Sciences study on the future of human spaceflight, and is the global director of Science Hack Day, a 24-hour worldwide event to get people excited about science. We exchanged emails about what space smells like, which of Saturn’s moons might be home to the most interesting life, and why we explore space at all. The interview has been edited for length and clarity.
What does space smell like?
Burnt almond cookies. Seriously! At least, that was what one astronaut reported after sniffing the inside of an air lock. In fact, no one can quite agree on what space smells like. Others have said everything from welding fumes to “wet clothes after rolling in snow.”
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
