Mars Express: PFS

The Martian atmosphere consists mainly of carbon dioxide and nitrogen with a very small proportion of water vapour and ozone. The PFS (Planetary Fourier Spectrometer) will measure the global atmospheric distribution of water vapour and other minor constituents with greater accuracy than previous missions. The PFS Principal Investigator is Dr. Vittorio Formisano, Istituto di Fisica dello Spazio Interplanetario, Rome, Italy.

The primary source for PFS data is the ESA Planetary Science Archive.

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node will host a copy of the PFS data archive on this web site when it becomes available. No PFS data have yet been received at the Geosciences Node.

More information about PFS is on the ESA web site.
