Check out some of NASA’s newest experiments on PopSci.
What happens when a spacecraft catches on fire?
Scientists have lit tiny flames on the ISS before, but the Spacecraft Fire Experiment (Saffire-I) will explore what happens during a larger fire.
For the safety of the ISS crew, the experiment will take place inside a special box on the empty Cygnus vessel, which would burn up in the atmosphere anyway after dropping off the ISS supplies. While the spacecraft fire burns, Saffire will measure temperature, flame growth, oxygen use, and more.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
