The cosmic ray all-particles spectrum is a very important result obtained by the NUCLEON space experiment. This spectrum was directly measured up to energies near 500 TeV. The ground-based experiments provide very large statistics but their results depend on applied models. The NUCLEON experiment allows to compare results of direct measurements and data of ground-based experiments. The all-particles spectrum is presented. The shape of this spectrum differs from the power-law dependence. This difference is caused by the universal «knee» found in the rigidity spectra measured by the NUCLEON experiment. The obtained all-particles spectrum is well consistent with the data from ground-based experiments HAWC and TAIGA.
