Mount, then a physicist in the WSU Department of Civil and Environmental Engineering, had been part of a team led by NASA’s Jet Propulsion Laboratory to develop the Orbiting Carbon Observatory (OCO), a sophisticated instrument to measure carbon dioxide from space.

It looked like a picture-perfect launch. The researchers had boarded buses from the launch site and were riding back to their hotel when they learned the news: The rocket carrying their satellite had failed to reach orbit. Instead, the … » More …

Science has been predicting and measuring our warming planet for more than a century now. But it was only in the last two decades that most Americans came to believe the earth’s temperature was indeed rising and that the main culprit is the growing amount of carbon dioxide in our atmosphere.

Now scientists are giving a lot of thought to another culprit: nitrogen. Like carbon dioxide, it’s seemingly benign—colorless, odorless, tasteless, and a foundation of life on our planet. Left alone, it tightly binds to itself in inert, two-atom molecules, or N2. It’s ridiculously commonplace, making up four-fifths of our atmosphere. It’s also a modern … » More …
