The European Space Agency
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. Marco Giuranna, Istituto di Astrofisica e Planetologia Spaziali, 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 is hosting a copy of the PFS data archive.

April 13, 2023. PFS Extended Mission 6 data through 31 Dec 2018 are now online.

October 10, 2018. PFS Extended Mission 6 data through 31 Dec 2017 are now online.

June 28, 2017. PFS Extended Mission 5 data through 29 Dec 2016 are now online.

February 12, 2016. PFS Extended Mission 4 data through 31 Dec 2014 are now online.

November 6, 2013. PFS Extended Mission 3 data through 31 Dec 2012 are now online.

September 27, 2011. PFS Extended Mission 3 data through 31 Dec 2010 are now online.

April 7, 2011. This site now has PFS data acquired between 23 June 2003 and 30 June 2010.
