Abstract

The Habitable Exoplanet Observatory (HabEx) is one of four concepts currently under study by NASA in preparation for the 2020 Astrophysics Decadal Survey. HabEx is designed to be the next-generation great observatory that has the capability to address physics of the cosmos, cosmic origins, and solar system and exoplanet science. HabEx is a space-based, four-meter diameter telescope with ultraviolet, optical and near-infrared imaging and spectroscopy capabilities, and at least 50 percent of the primary five-year mission will be dedicated to community involvement through a competed and funded Guest Observer (GO) program.
