The Imaging Ultraviolet Spectrograph (IUVS) for the MAVEN Mission

The Imaging Ultraviolet Spectrograph (IUVS) is one of nine science instruments aboard the Mars Atmosphere and Volatile and EvolutioN (MAVEN) spacecraft. MAVEN, launched in November 18, 2013 and arriving at Mars in September 2014, is designed to explore the planet’s upper atmosphere and ionosphere and examine their interaction with the solar wind and solar ultraviolet radiation. IUVS is one of the most powerful spectrographs sent to another planet, with several key capabilities: (1) separate Far-UV & Mid-UV channels for stray light control, (2) a high resolution echelle mode to resolve deuterium and hydrogen emission, (3) internal instrument pointing and scanning capabilities to allow complete mapping and nearly-continuous operation, and (4) optimization for airglow studies.

More than three-dozen managers, scientists, engineers, technicians, and instrument makers at the Laboratory for Atmospheric and Space Physics contributed to the design, fabrication, and test of IUVS. Their expertise, dedication, and hard work transformed the IUVS concept into a world-class scientific instrument.
