PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.




GCMS - Gas Chromatograph Mass Spectrometer

Overview

The Huygens Gas Chromatograph Mass Spectrometer (GCMS) was designed to provide an accurate analysis of Titan's atmospheric composition along the descent trajectory of the Huygens Probe. It measured the altitude profiles of the atmospheric constituents, isotopic ratios, and trace species.



Data Example


Plot of methane mole fraction as a function of time (and therefore altitude) as measured by Huygens/GCMS.




The GCMS Tabs
