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.

Goals:

  • 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

Observations:

  • 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
