Methane gas samples from a variety of locations were collected and measured by gas chromatography-mass spectrometry, GC/MS, infrared and diode laser absorption techniques in order to test the feasibility of carrying out remote sensing of methane on other solar system bodies. A special open path near infrared diode laser spectrometer was built and tested during this study. It featured a high resolution tilt and pan mechanism and fiber optic cables to allow spectroscopic measurements to be made over wide areas and distances.
