Dean Pesnell, the SDO Project Scientist, explains how the the Extreme Ultraviolet Variability Experiment (EVE) instrument will allow us to better measure solar irradiance in extreme ultraviolet wavelengths. This type of irradiance, which is absorbed completely by Earth's upper atmosphere, can be dangerous to astronauts and electronics in space.

SDO will help scientists better understand solar variability and aid in predictions of space weather. Ka band dishes at White Sands, New Mexico will be the go-between the satellite and the Mission Control Center at Goddard Space Flight Center.

For more info: http://www.nasa.gov/LRO The Autonomous Star Trackers provide attitude data and motion rate of the satellite. They are based on a radiation hardened design and proprietary algorithms that ensure accurate and robust 3-axes attitude determination. These same instruments most recently flew onboard NASA's Messenger and Mars Reconnaissance Orbiter missions.
