Ultra high energy (UHE) neutrinos play a vital role in the new age of multi-messenger astronomy. While light can be bent or absorbed by intervening dust and cosmic rays can be significantly deflected by magnetic fields, UHE neutrinos make their journey to us nearly unimpeded, revealing a direct line to their source and providing insight into the mechanisms of their creation. With projects including IceCube, ARA, ANITA and ARIANNA, neutrino astronomy has made great strides in the past decade. However, energies beyond 100 PeV cannot cost efficiently be targeted with with optical sensors due to the relatively short attenuation length of light. Radio arrays searching for Askayran emission can cover a much larger effective area for a fraction of the price. The Radio Neutrino Observatory in Greenland (RNO-G) will be capable of detecting these cosmogenic neutrinos with a view of the northern sky, acting as a pathfinder for the radio component of IceCube Gen-2. We explore the inspiration, design, and rollout of this new observatory, which will deploy 35 stations over the next 3 years.
