Mission Architecture Study Results for a Space-Based Gravitational-Wave Observatory (SGO)
Abstract
The low-frequency band (0.0001 - 1 Hz) of the gravitational wave spectrum has a rich collection of astrophysical sources, and the Laser Interferometer Space Antenna (LISA) concept has been the key mission to cover this science for over twenty years. Although highly ranked in the 2010 Decadal Survey for the spectacular science return, tight budgets have forced NASA to consider a reformulation of the LISA mission concept at a lower cost point, even if at the expense of some of the science. We report the results of a mission architecture study that considered various options according to cost, risk, technical readiness, and the ability to address the Decadal-endorsed science goals.
