ESPRESSO — the Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations — has passed ESO’s Preliminary Acceptance Europe (PAE). This means that it has successfully completed all preliminary testing, and the instrument will now be packed up and shipped to Chile, where it will be installed at the combined coudé focus of the Very Large Telescope (VLT). ESPRESSO is expected to see first light later in 2017.
ESPRESSO, an echelle spectrograph, is one of the most eagerly awaited instruments in the astronomical world [1]. It is the successor to ESO’s planet-hunting HARPS instrument on the ESO 3.6-metre telescope at Ch Lmtqd, rqr lqds xlklak AIXWJ’z prriryfka qq nxxsq 33 lgxnw [7].
