Canadian firm to develop interferometer for Mars mission


Quebec City, QC – Power and automation technology group ABB says it has been chosen by the Canadian Space Agency to develop a main component on a satellite that will be launched in 2016 to the planet Mars.

ABB will supply a spatial interferometer that will constitute the main part of an instrument in the satellite that will probe the atmosphere of Mars in search of biological sources of methane. The instrument, known as MATMOS (Mars Atmospheric Trace Molecule Occultation Spectrometer), is a partnership between the California Institute of Technology (Caltech), the CSA and NASA’s Jet Propulsion Laboratory (JPL).

MATMOS has been chosen by NASA and the European Space Agency for launch on board the ExoMars Trace Gas Orbiter, slated for launch in 2016. Its destination will be to orbit around the red planet.

The first objective of the mission is to characterize the chemical composition of the Mars atmosphere. The spectrometer, which contains the interferometer designed and built by ABB, will detect methane molecules and trace them in the Mars atmosphere. It will be able to measure the distribution of methane and determine the type (biological or geological) and will also measure other trace gases.

The development of the interferometer in MATMOS was inspired by the ABB-built payload supplied to the Canadian Space Agency in their ACE/SciSat-1 satellite. This satellite has been in orbit for more than seven years and ABB says its performance has far exceeded the expectations of the scientific community.
