NIRPS is a new fiber-fed high spectral resolution spectrograph assisted by adaptive optics installed on the 3.6m telescope of ESO at La Silla, Chile. Operated simultaneously with HARPS, NIRPS covers the Y, J, and H bands. In this talk, I will describe the objectives of the NIRPS consortium that has been allocated 725 GTO nights over 5 years. A third of this time is dedicated to in-depth spectral characterizations to provide detailed high-fidelity high signal-to-noise transmission and emission spectra as well as large comprehensive atmospheric and orbital architecture surveys that will be done for more than 75 exoplanets from ultra-hot Jupiters to temperate terrestrial planets. Over the program's first two years, we have prioritized the best exoplanets, including many JWST targets. I will present the first results obtained since the start of operation, including the detections of escaping atmospheres and the presence of molecules and atoms in the atmospheres of warm Neptunes to hot Jupiters. These results showcase the potential of NIRPS to deliver high-fidelity atmospheric spectra to constrain the formation and evolution of exoplanets at the statistical level.
