 I'm Robert Cahalan and currently director of the Sun Climate Research Center at Goddard and also the project scientist for a space mission called Solar Radiation and Climate Experimental Source, SORCE, that's an acronym. And then we have a new launch of a satellite called Takati this summer and then a follow-on launch in 2016 of the Total and Spectral Solar Radiance Sensor, TESIS we call it. So things looking at the sun but trying to understand how they impact the earth.
