In September 2007, NASA issued a proposal call for Astrophysics Strategic Mission Concept Studies, for missions that may be carried out in the next decade, or for which technology development funding is sought in the next decade. In February 2008, a total of 19 study proposals were selected for one-year studies.

Study results are expected to be provided as input to the upcoming Astronomy and Astrophysics Decadal Survey.
