NASA Assigns "Living With a Star Missions" to APL
NASA has authorized the John Hopkins University Applied Physics Laboratory (APL), Laurel, Md., to proceed with the implementation of the Geospace missions under NASA's existing "Living with a Star" contract with APL. The Living with a Star (LWS) program seeks to address how the variability in the sun affects life on Earth as well as its affect on space weather. LWS sets out to quantify the physics, dynamics and behavior of the Sun-Earth system over the 11-year solar cycle and improve understanding of solar variability and disturbances on terrestrial climate change. It will also provide data and scientific understanding aimed at developing a predictive capability for space weather affects. In addition, LWS will give scientists a detailed characterization of radiation environments useful in the design of more reliable electronic components for air and space transportation systems. The two missions assigned to the APL make-up the LWS Geospace Project. These missions were recently identified in a study completed by the Geospace Mission Definition Team, a group tasked by NASA Headquarters to identify LWS Geospace Project goals and priorities. The two missions are the Ionosphere-Thermosphere Mapper Mission (ITM) and the Radiation Belt Mapper Mission (RBM). LWS is part of the Sun-Earth Connection theme within the Office of Space Science at NASA Headquarters in Washington. NASA's Goddard Space Flight Center, Greenbelt, Md. manages the LWS program.
