The Imaging Ultraviolet Spectrograph (IUVS) aboard the MAVEN spacecraft is one of the most powerful spectrographs sent to another planet, with several key capabilities:
- Separate Far-UV & Mid-UV channels for stray light control;
- A high resolution echelle mode to resolve deuterium and hydrogen emission;
- Internal instrument pointing and scanning capabilities to allow complete mapping and nearly-continuous operation; and
- Optimization for airglow studies.
The images and videos collected here represent just some of the highlights from the IUVS instrument, since it began collecting science observations at Mars in October 2014.
