The electromagnetic spectrum, spanning energies and wavelengths from radio waves to gamma rays, encompasses all forms of light. Infrared radiation, located in the range just beyond visible light, is emitted by all matter and is very useful in gathering data about Earth and space. In this video segme
How Would You Turn a Bolt in Space?
Tools such as saws, hammers, and levers are designed to make work easier. Sometimes, the environment in which a person works dictates whether or not a certain tool will get the job done. In the microgravity environment of space, astronauts are often required to do experiments or simple repairs. On Earth, gravity helps anchor a person to the ground, making tightening a bolt a rather simple activity. In this video segment from NASA Brain Bites™, learn why engineers have had to develop different types of bracing systems—a whole new set of tools—to assist astronauts working in space. This video is available in both English and Spanish audio, along with corresponding closed captions.

This video adapted from Spanner Films describes the effects of changes to permafrost, the frozen layer of soil and ice that underlies much of Alaska, caused by a warming climate. Permafrost, some of which has persisted since the last ice age, more than 10,000 years ago, is melting rapidly. In affect
