[1][2][3] The NESSI instrument was mounted in 2014 on a 2.4 meter telescope at the Magdalena Ridge Observatory in Socorro County, New Mexico, USA,[4] achieving first light on 7 April 2014.

It is partly funded by NASA's Experimental Program to Stimulate Competitive Research, in partnership with the New Mexico Institute of Mining and Technology.

[2] The NESSI spectroscope was mounted on the institute's 2.4 meter telescope at the Magdalena Ridge Observatory in Socorro County, New Mexico, USA,[4] and its first exoplanet observations began on April 7, 2014.

NESSI achieved first light on the Hale Telescope in Feb, 2018 and was undertaking a series of observations to establish its sensitivity and precision for exoplanet spectroscopy.

The novel technology is expected to achieve high definition readings by using algorithms to calibrate and compensate for time-variable telluric features and instrumental variability throughout an observation.
