CU-Boulder Extreme Ultraviolet Variability Experiment, or EVE

A $32 million University of Colorado Boulder instrument package set for launch Feb. 10 by NASA should help scientists better understand the violent effects of the sun on near-Earth space weather that can affect satellites, power grids, ground communications systems and even astronauts and aircraft crews. The CU-Boulder Extreme Ultraviolet Variability Experiment, or EVE, will fly on NASA's Solar Dynamics Observatory known as SDO, the space agency's first mission as part of its "Living With a Star" program. EVE will measure rapid fluctuations in the sun's extreme ultraviolet, or EUV, output that can have profound effects on Earth's upper atmosphere.
