The NUCLEON space observatory is a direct cosmic ray spectrometer designed to study cosmic ray nuclei with Z = 1−30 at energies 10 12 −10 15 eV. It was launched as an additional payload onboard the Russian Resource-P No. 2 satellite. In this work B/C, N/O and subFe/Fe ratios are presented. The experiment has worked for half of its expected time, so the data have preliminary status, but they already give clear indications of several astrophysical phenomena, which are briefly discussed in this paper.

“…2) are four planes of the charge measurement system, a carbon target, six planes of the energy measurement system using the KLEM method (KLEM system tracker), three double-layer planes of the scintillator trigger system, and a small aperture ionization calorimeter (25 × 25 cm 2 ). Details of the detector design are provided in the articles [33,34,35,36,37]. On December 28, 2014, the NUCLEON detector was launched into a sun-synchronous orbit.…”

“…It is expected that the systematic errors of the data are mainly related to uncertainties of the event trigger operation and they are estimated to be approximately 25% in absolute intensity and ±0.06 in the common spectral index of the spectra. The systematics related to energy determination by the both methods were tested in CERN beam tests experiments [36] and expected to be ∼5%. The IC method and the KLEM method of energy measurement are in fact two different experiments with different physics of generation of the trigger, jointed in one experimental setup.…”

Data from the NUCLEON space observatory give a strong indication of the existence of a new universal cosmic ray "knee", which is observed in all groups of nuclei, including heavy nuclei, near a magnetic rigidity of about 10 TV. Universality means the same position of the knee in the magnetic rigidity scale for all groups of nuclei. The knee is observed by both methods of measurement of particles energy implemented in the NUCLEON observatory-the calorimetric method and the kinematic method KLEM. This new cosmic ray "knee" is probably connected with the limit of acceleration of cosmic rays by some generic or nearby source of cosmic rays. *
