The results, they say, could tell us more about the cores of giant planets.<p>"Diamonds have very special properties, besides being very expensive and used for jewelrey etc.," says <a href="https://www-pls.llnl.gov/?url=about_pls-scientific_staff-smith_r">Raymond Smith</a>, a researcher at <a href="https://www.llnl.gov/">Lawrence Livermore National Laboratory</a> in California. "It's the hardest substance known to man."<p>And diamonds aren't just here on Earth.

The satellite could revolutionize our understanding of where this greenhouse gas comes from and where it goes.

The <a href="http://oco.jpl.nasa.gov/">Orbiting Carbon Observatory-2</a> (OCO-2) will be the first U.S. spacecraft dedicated to seeing the greenhouse gas from orbit, and could pave the way for new technology to enforce future global warming treaties.<p>But first OCO-2 needs to make it off the ground.
