Cassini exploration of the planet Saturn: A comprehensive review
AP Ingersoll - Space science reviews, 2020 - Springer
Abstract Before Cassini, scientists viewed Saturn's unique features only from Earth and from

Search for Dark Matter Ionization on the Night Side of Jupiter with Cassini
We present a new search for dark matter (DM) using planetary atmospheres. We point out
that annihilating DM in planets can produce ionizing radiation, which can lead to excess …

Compositional measurements of Saturn's upper atmosphere and rings from Cassini INMS: An extended analysis of measurements from Cassini's Grand Finale orbits
The Cassini spacecraft's final orbits sampled Saturn's atmosphere and returned surprisingly
complex mass spectra from the Ion and Neutral Mass Spectrometer. Signal returned from the …
