Influence of spacecraft outgassing on the exploration of tenuous atmospheres with in situ mass spectrometry

Wurz, P.; Altwegg, K.; Balsiger, H. +10 more

In situ mass spectrometry has been a powerful tool in many space missions to investigate atmospheres and exospheres of different bodies in the solar system. Applying new technologies, the mass spectrometers have become increasingly more sensitive. In this study, we show that spacecraft outgassing, which can never be completely prevented, will be t…
