No present or approved spacecraft mission has the capability to provide high angular resolution imaging of solar or magnetospheric radio bursts or of the celestial sphere at frequencies below the ionospheric cutoff. In this presentation, we review a NASA MIDEX-class mission to perform such imaging in the frequency range 30 kHz to 15 MHz. The focus of the mission, the Solar Imaging Radio Array (SIRA), is solar and exploration- oriented, with emphasis on improved understanding and application of radio bursts associated with solar energetic particle (SEP) events and on tracking shocks and other components of coronal mass ejections (CMEs). The data stream will also permit high angular resolution mapping of the celestial sphere at frequencies below 15 MHz, permitting detection of numerous astrophysical objects and extension of their observed spectra to much lower frequencies. SIRA will require 12 to 16 micro-satellites to establish a sufficient number of baselines with separations on the order of kilometers. The constellation consists of microsats located quasi-randomly on a spherical shell, initially of radius 5 km. The baseline microsat is 3-axis stabilized with body-mounted solar arrays and an articulated, Earth-pointing high gain antenna. The constellation will likely be placed at L1, which is the preferred location for full-time solar observations. Detailed mission science and technology goals will be reviewed.
