EVE Rocket Program
EUV Variability Experiment
Calibrating the EVE instrument in space
The EVE Rocket Program’s objective is to calibrate the EUV Variability Experiment (EVE) instrument on the Solar Dynamics Observaotry (SDO) mission. Built and controlled by LASP, the EVE instrument measures solar extreme ultraviolet (EUV) irradiance, or the energy from the Sun that heats most of Earth’s thermosphere. Sounding rocket under-flight calibration flights are planned annually throughout the SDO mission’s duration to ensure the accuracy of EVE-collected data by measuring any changes to the EVE instrument in space. The LASP rocket payload was rebuilt in 2006 to better accommodate the SDO EVE channels. This rebuild included larger rocket skins and a new control section.
