Abstract
MINOS is a long baseline neutrino oscillation experiment designed to make precision measurements of the neutrino mixing parameters associated with the atmospheric neutrino mass splitting. Using a high powered neutrino beam from the Main Injector (NuMI) facility at Fermilab, it compares the neutrino energy spectrum for charged current muon neutrino interactions observed in two large detectors located at Fermilab and in the Soudan mine in northern Minnesota at a distance of 735~km. We present the $\nu_{\mu}$ disappearance analysis of the final data set from the first year of data corresponding to $1.27\times 10^{20}$~protons on target. In June 2006 MINOS started its second year of data-taking and as of now it has accumulated over $2\times 10^{20}$~protons on target, the largest sample of neutrino interactions collected to date, current status and performance will be presented.
