Overview

Ball Aerospace built the Goddard High Resolution Spectrograph (GHRS) as one of the five, first-generation instruments installed on the Hubble Space Telescope.

GHRS was designed to detect ultraviolet light, which is emitted by all stars, planets, and galaxies. By looking at the ultraviolet light of stars, it can analyze the chemical composition and the gases that surround them to help researchers understand the first moments of our universe.

GHRS successfully collected data for seven years. It was replaced during Hubble’s second servicing mission by the Ball Aerospace-built Space Telescope Imaging Spectrograph in 1997.
