Less than 20 years after the discovery of the first extrasolar planet, exoplanetology is rapidly growing with more than one discovery every week on average since 2007. An important step in exoplanetology is the chemical characterization of exoplanet atmospheres. It has recently been shown that molecular signatures of transiting exoplanets can be studied from the ground. To advance this idea and prepare more ambitious missions such as THESIS, a dedicated spectrometer named the New Mexico Tech Extrasolar Spectroscopic Survey Instrument (NESSI) is being built at New Mexico Tech in collaboration with the NASA Jet Propulsion Laboratory. NESSI is a purpose-built multi-object spectrograph that operates in the J, H, and K-bands with a resolution of R = 1000 in each, as well as a lower resolution of R = 250 across the entire J/H/K region.
