TL;DR: The detection of complex organic molecules with masses higher than 200 atomic mass units in ice grains emitted from Enceladus indicates the presence of a thin organic-rich layer on top of the moon’s subsurface ocean.
Journal ArticleDOI
Low-mass nitrogen-, oxygen-bearing, and aromatic compounds in Enceladean ice grains
Nozair Khawaja,Nozair Khawaja,Frank Postberg,Frank Postberg,Jon K. Hillier,Fabian Klenner,Fabian Klenner,Sascha Kempf,Lenz Nölle,Lenz Nölle,René Reviol,Z. Zou,Ralf Srama +12 more
TL;DR: In this article, a compositional analysis of CDA mass spectra from organic-bearing ice grains was performed on the Enceladus seafloor and the results indicated that low-mass amines, carbonyls, and aromatic compounds were the best candidates for the N- and O-bearing compounds.
Journal ArticleDOI
Analog Experiments for the Identification of Trace Biosignatures in Ice Grains from Extraterrestrial Ocean Worlds.

TL;DR: This work investigates with an analog experiment the spectral appearance of amino acids, fatty acids, and peptides in water ice grains, together with their detection limits, as applicable to spaceborne mass spectrometers, and finds the detection limits of these key biosignatures to be at the μM or nM level.
Journal ArticleDOI
Discriminating Abiotic and Biotic Fingerprints of Amino Acids and Fatty Acids in Ice Grains Relevant to Ocean Worlds.
Fabian Klenner,Fabian Klenner,Frank Postberg,Frank Postberg,Jon K. Hillier,Nozair Khawaja,Nozair Khawaja,Morgan L. Cable,Bernd Abel,Bernd Abel,Sascha Kempf,Christopher R. Glein,Jonathan I. Lunine,Jonathan I. Lunine,Robert Hodyss,René Reviol,René Reviol,Ferdinand Stolz,Ferdinand Stolz +18 more
TL;DR: The survivability and ionization efficiency of large organic molecules during impact ionization appears to be significantly improved when they are protected by a frozen water matrix, infer from the experimental results that encounter velocities of 4-6 km/s are most appropriate forimpact ionization mass spectrometers to detect and discriminate between abiotic and biotic signatures.
Journal ArticleDOI
Analogue spectra for impact ionization mass spectra of water ice grains obtained at different impact speeds in space.

TL;DR: It is shown that the analogue experiment can reproduce impact ionization mass spectra of ice grains obtained over a wide range of impact speeds, aiding the quantitative analyses ofmass spectra from space.
