This site has information on instruments and data related to our research in visible-infrared spectrometer studies of Mars and Earth.

Mars data sets include:

(1) 1969 Mariner Mars Infrared Spectrometer (IRS)

(2) 1971 Mariner Mars Interferometer Spectrometer (IRIS)

(3) 1989 Phobos 2 Imaging Spectrometer for Mars (ISM)

(4) 1996 Mars Global Surveyor TES

(5) 2001 Mars Odyssey THEMIS.

For these data sets, we also examine the instrument calibrations, recover missing data and documentation, and make all recovered information publicly available to help open these investigations to everyone.

Our terrestrial measurements include:

(1) Airborne: SEBASS (7.5-13.5 �m). SEBASS is the only airborne hyperspectral imager that measures with a sensitivity and spectral resolution comparable to laboratory data, making it most suitable for detailed studies of spectral behavior.

(2) Field spectrometers (hyperspectral). Our field spectrometers are the only instruments used for planetary work that measure in a manner very similar to the 2003 lander Mini-TES.

(3) Laboratory spectrometer (hyperspectral) measurements of field samples. Our laboratory spectrometer is the only instrument used for planetary research independent of the TES/THEMIS/Mini-TES team that measures the full wavelength range measured by TES.

IRS Data

Spectra acquired of Mars by the 1969 Mariner Mars 7 Infrared Spectrometer (IRS) spanning the wavelength region 1.8 - 14.4 �m have recently been recovered and calibrated in the region from ~5 - 14.4 �m, and are available to all interested researchers. IRS spectra remain an important resource because of their unique range of spectral coverage, unique temporal coverage, and high quality.

IRS History

Members of the original 1969 Mariner Mars Infrared Spectrometer (IRS) team met near Berkeley, CA in Aug. 1999 to collaborate on recovery of the IRS data set, history, and equipment. IRS was the first infrared spectrometer flown to another planet. The data set remains a unique and valuable research resource, and the project is an important part of the history of spaceflight, and of the exploration of Mars.

This work is continuing, and is sponsored by the Lunar and Planetary Institute and NASA. Additional information is available here.
