The
European Space Agency
Mars Express: OMEGA
The OMEGA IR
Mineralogical Mapping Spectrometer determines the
mineral content of the Martian surface and the molecular
composition of the atmosphere by analyzing sunlight
reflected from the surface and diffused through the
atmosphere. It also performs similar analyses on heat
radiation emitted from the surface. Information from
Omega will contribute to our understanding of the
structure of the Martian landscape and the role played
by water over timescales ranging from seasons to
billions of years. The OMEGA
Principal Investigator is Dr. Jean-Pierre Bibring,
Institut d'Astrophysique Spatiale, Orsay, France.
The primary source for OMEGA data is the
ESA Planetary Science Archive.
Through a cooperative agreement between ESA and NASA,
the PDS Geosciences Node is hosting a copy of the OMEGA data
archive.
More information about OMEGA is on the
OMEGA
web site.
The
Mars
Orbital Data Explorer can be used to search for
OMEGA data.
April 10, 2007. This site now has OMEGA
data acquired from 19 February 2003 to 8 July 2005
(cruise phase through orbit 1899).
