NASA has selected five proposals for concept studies of missions to help improve understanding of the dynamics of the Sun and the constantly changing space environment with which it interacts around Earth. The information will improve understanding about the universe as well as offer key information to help protect astronauts, satellites, and communications signals – such as GPS – in space.
Each of these Medium-Class Explorer proposals will receive $1.25 million to conduct a nine-month mission concept study. Following the study period, NASA will choose up to two proposals to go forward to launch. Each potential mission has a separate launch opportunity and timeframe.
“We constantly seek missions that use cutting edge technology and novel approaches to push the boundaries of science,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “Each one of these proposals offers the chance to observe something we have never before seen or to provide unprecedented insights into key areas of research, all to further the exploration of the universe we live in.”
The Sun sends out a constant stream of particles and energy, which drives a complex space weather system near Earth and can affect spacecraft and astronauts. NASA has chosen five new mission concept studies for further development to study various aspects of this dynamic system.
