Hasso Niemann (1933-2013) was a pioneer in the application of mass spectrometry to the study of planetary atmospheres and surfaces, from early pioneering research in the Earth's upper atmosphere, to the upper atmosphere of Venus, an entry probe of the Jovian atmosphere, and both the atmosphere and surface of Saturn’s moon Titan. For more than 30 years Hasso led the mass spectrometry group at Goddard which today is operating a multi-technique chemical laboratory on Mars—including a mass spectrometer.

Papers will be entertained on the subject of mass spectrometers and closely related instruments (gas chromatographs, tunable laser spectroscopy…) deployed in planetary environments. Papers on past, present and future instruments on planetary missions will be entertained.
