Abstract Edison is a proposed large-aperture, radiatively-cooled space observatory planned to operate at wavelengths between 2 and 130μm or longer. Current estimates for the telescope allow an aperture of 1.7 m which will achieve a final equilibrium temperature of about 30 K, although use of cryocoolers may permit temperatures below 20 K.Edison will be a powerful tool to investigate our Solar System, as well as planetary material around distant stars. At near- and mid-infrared wavelengths, where planetary material emits most of its radiation,Edison will be the most sensitive photometric and spectroscopic observatory under current consideration by the space agencies. With its large aperture,Edison will be able both to resolve the structure in nearby circumstellar “Vega disks” and to discriminate faint IR emission in the crowded environment of the galactic plane. With its long lifetime,Edison will allow extensive follow-up observations and increase the likelihood of catching transient events. We proposeEdison as a precursor to elements of a future space-based IR interferometer.
