THEMIS: NASA's First Five Spacecraft Constellation Mission


Description:

Provided by: Laboratory for Atmospheric and Space Physics THEMIS, Greek goddess of justice, is also an acronym for Time History of Events and Macroscale Interactions during Substorms. The launch of THEMIS in 2007 marked the first time in NASA's history to launch five identical space probes on a single Delta-II launch vehicle. Among other things, the THEMIS mission has addressed crucial questions regarding a phenomenon called the magnetospheric substorm instability that contributes to the explosive release of solar wind energy within the space around Earth. In this LASP public lecture from April 7, 2009, Dr. Xinlin Li describes engineering challenges and the mission and science of THEMIS.
