Exploration by Cassini

From 2004 to 2017, the Cassini spacecraft, a collaborative mission involving NASA, the European Space Agency, and the Italian Space Agency, extensively studied Saturn and its moons. The mission unveiled Enceladus' remarkable features, including geysers at its south pole that eject gas and ice grains into space.

Simulation of Detection  Methods

Klenner's team conducted laboratory experiments to simulate the detection of extraterrestrial cells in ice grains. By employing mass spectrometry techniques, they assessed the feasibility of identifying cellular material using spacecraft dust analyzer instruments.

Potential Signatures of Life

The study demonstrated that instruments onboard spacecraft could detect amino acids and fatty acids, indicative of cellular material. These findings contribute to the development of advanced instruments for future missions to Enceladus and Europa.
