  The decay $K^+\to\pi^+\nu\bar{\nu}$ is highly suppressed in the Standard
Model (SM), while its rate can be predicted with minimal theoretical
uncertainty. The branching ratio (BR) for this decay is thus a sensitive probe
of the flavor sector of the SM; its measurement, however, is a significant
experimental challenge. The primary goal of the NA62 experiment is to measure
${\rm BR}(K^+\to\pi^+\nu\bar{\nu})$ with 10% precision. NA62 took data in pilot
runs in 2014 and 2015, reaching the design beam intensity. The status of the
experiment and the prospects for the measurement of ${\rm
BR}(K^+\to\pi^+\nu\bar{\nu})$ are presented.
