We're looking at Earth science observing our planet. Also space science looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level using ourselves as test subjects.

It's absolutely stupid that we live without an ozone layer. We have men we've got rockets we've got saran wrap - fix it!

We are near very near to an end to the eurozone crisis... The worst - in the sense of the fear of the eurozone breaking up - is over. But the best isn't there yet.

Despite Arizona's remarkable growth in recent years we have met the current federal health standards for ozone pollution and the Environmental Protection Agency recently approved our dust control plan.
