Astrophysical hypotheses suggest the existence of neutrinos beyond the energy range currently
reached by optical detectors (> 10 PeV). The observation of such particles by capturing the
coherent emission of their interaction in ice, i.e. Askaryan radiation, is the aim of the Radio
Neutrino Observatory in Greenland (RNO-G). Located at Summit Station, RNO-G represents the
first neutrino detector oriented towards the Northern sky, and it will play a role in the future shaping
of the larger IceCube-Gen2 Radio Array. The first installed stations of RNO-G are currently active
and collecting data, while the full array will reach completion within the next years. The plan
includes a grid of 35 radio stations, each designed to be low powered and autonomous. Learning
from previous radio detectors, each station includes both shallow antennas mainly for cosmic-ray
identification, and in-ice deep antennas with a phased array trigger for detection and reconstruction.
We present the motivation, design and current status of the detector.
