From Viking-Era TV-GC-MS to Next-Generation In Situ Biosignature Detection: Liquid-Based, Stand-Off, and Integrated Instrument Suites for Space Missions

To the point

Victor Abrahamsson and IKisik Kanik summarize how space missions are moving from Viking-era TV-GC-MS to next‑generation liquid methods, biosensors, nanopore sensing, and stand‑off spectroscopy for rapid, low‑mass life detection, emphasize that no single technique is enough, and stress that robust sample preparation and validation are essential to reach about 1 ppb detection of lipids, amino acids, and informational polymers in harsh matrices, while highlighting ongoing miniaturization, complementary optical methods, ion mobility, and automated end‑to‑end workflows in mission‑ready suites like EMILI, CMOLD, and MINAR to enable comprehensive in situ analyses for Ocean Worlds such as Europa and Enceladus.
