    <dct:description>&lt;p&gt;The Near-InfraRed Planet Searcher (NIRPS) is designed to be an&lt;br&gt; ultra-stable infrared spectrograph to be installed on ESO&amp;rsquo;s 3.6 m Telescope&lt;br&gt; in La Silla, Chile. NIRPS is an adaptive optics (AO) fiber-fed spectrograph&lt;br&gt; operating from 0.98 to 1.8 &amp;mu;m and will be operated simultaneously with the&lt;br&gt; optical high-resolution spectrograph HARPS. NIRPS can operate in two modes&lt;br&gt; fed by two different fiber links permanently mounted at the Cassegrain focus&lt;br&gt; that use either 0.4 arcsecond-fibers for the High Accuracy Mode (HAM) or 0.9&lt;br&gt; arcsecond-fibers for the High Efficiency Mode (HEM). The wavelength range of&lt;br&gt; NIRPS is optimal for low-mass M dwarfs and the simultaneous NIRPS and HARPS&lt;br&gt; observations will improve stellar activity filtering methods given their&lt;br&gt; different wavelength coverages. The NIRPS front-end and AO system were&lt;br&gt; already tested on-sky at La Silla. The spectrograph and back-end is to be&lt;br&gt; shipped to La Silla and installed by end of 2021. Already we have adapted the&lt;br&gt; state-of-the-art ESPRESSO data reduction pipeline for NIRPS, obtained&lt;br&gt; accurate wavelength solutions with a Uranium Neon lamp, and obtained drift&lt;br&gt; stability results below 50 cm/s with a Fabry&amp;ndash;P&amp;eacute;rot etalon. We discuss the&lt;br&gt; current and expected instrument performance and the expected science results&lt;br&gt; of NIRPS.&lt;/p&gt;</dct:description>
