  The NOvA long-baseline neutrino oscillation experiment is currently under
construction and will use an upgraded NuMI neutrino source at Fermilab and a
14-kton detector at Ash River, Minnesota to explore the neutrino sector. NOvA
uses a highly active, finely segmented detector design that offers superb event
identification capability, allowing precision measurements of \nu_e/\nu_e-bar
appearance and \nu_\mu/\nu_\mu-bar disappearance, through which NOvA will
provide constraints on \theta_13, \theta_23, |\Delta m^2_atm|, the neutrino
mass hierarchy, and the CP-violating phase \delta. In this article, we review
NOvA's uniquely broad physics scope, including sensitivity updates in light of
the latest knowledge of \theta_13, and we discuss the experiment's construction
and operation timeline.
