  Recent results a future prospects of the NA62 experiment at CERN SPS are
presented. The NA62 experiment performed the most precise measurement of the
ratio $R_K$ of the $K^+\rightarrow e^\pm\nu$ and K^+\rightarrow \mu^\pm\nu$
decay rates using the full data set collected in 2007. The result is in
agreement with the Standard Model expectation. The ultra-rare decay
$K^+\rightarrow\pi^+\nu\bar{\nu}$ is an excellent processes to make tests of
new physics at the highest scale complementary to the LHC thanks to their
theoretically cleanness. The NA62 experiment at CERN SPS aims to collect of the
order of 100 $K^+\rightarrow\pi^+\nu\bar{\nu}$ events in two years of data
taking, keeping the background at the level of 10%.
