Abstract
The Fourier-Kelvin Stellar Interferometer (FKSI) mission is a two-telescope infrared space interferometer with a 12.5 meter baseline on a boom, operating in the spectral range 3 to 8 (or 10) microns, and passively cooled to about 60 K. The main goals for the mission are the measurement and characterization of the exozodiacal emission around nearby stars, debris disks, and the atmospheres of known exoplanets, and the search for Super Earths around nearby stars. We discuss progress on this mission in the context of the upcoming Decadal Survey, in particular how FKSI is ideally suited to be an Exoplanet Probe mission in terms of crucial observations which should be done before a flagship mission can be undertaken, as well as technical readiness, cost, and risk.
