Imaging Ultraviolet Spectrograph (IUVS)
The Imaging Ultraviolet Spectrograph (IUVS) is a part of the Remote Sensing (RS) Package and measures global characteristics of the upper atmosphere and ionosphere via remote sensing.
- Provides global-scale measurements of major molecules, atoms, ions and isotopes in the Mars atmosphere & corona, while deriving key properties such as exobase and ionosphere altitudes
- IUVS provides major constraints on escape processes and measures the lower atmosphere
- Vertical profiles to characterize composition & structure
- Global images to characterize spatial distribution & variability
- Coronal Scans for “Hot Oxygen” and D/H ratio determination
- Stellar occultations for vertical CO2 profiles to characterize the underlying lower altitude atmosphere
Technical details and heritage:
- Imaging spectroscopy from 110-340 nm, with resolution of 0.5 – 1.0 nm.
- Vertical resolution of 6 km on limb, horizontal resolution of 200km
- Detectors: Image-intensified 2-D active pixel sensors
- Most recent heritage from AIM CIPS
Nick Schneider (LASP) is the instrument lead for the IUVS. For more about Schneider, visit: http://bit.ly/NSchneider.
