Summary:
Johns Hopkins and NASA engineers will collaborate on developing a space-based fiber optic laser system to track atmospheric changes caused by global warming.

Mounted inside a satellite high above the Earth, a powerful fiber-optic laser system, no larger than a laptop computer, fires an ultraviolet beam toward the planet. The beam strikes gas molecules such as ozone, sulfur and carbon dioxide, then bounces back to the satellite, carrying critical information about the health of the atmosphere.
